Referring a Patient for Dental Clearance in Houston or Katy: What to Send and What Comes Back

When a surgeon, cardiologist, oncologist or transplant team needs to know whether a patient's mouth is ready for a major medical procedure, the request usually starts with a form and a deadline. This dental clearance referral guide is written for the people who send that request in the Houston area: physicians, physician assistants, nurse practitioners, nurse navigators and surgery schedulers in Houston, Katy, Cypress, Sugar Land, Richmond, Fulshear and the Memorial area. It is also for patients who were handed a form and asked to "get dental clearance" before a surgery date.

It covers what to send, how to word the question, what a clearance letter usually contains, how timelines work when treatment is needed, and which medication and anesthesia questions may come back to the prescribing physician.

If you want the patient-side version, organized by procedure (transplant, chemotherapy or radiation, joint replacement, heart valve surgery), our guide to dental clearance before major surgery covers that. This page is the referring-office side, and it does not repeat that material.

The short answer

A good referral sends four things: the planned procedure and its date, the specific question the medical team needs answered, a current medication list, and a way to reach the person who will read the reply. What comes back is a short written answer to that question, plus a treatment plan and timeline if treatment is needed first. The dental team documents findings and completes needed treatment when appropriate. The decision to proceed with the medical procedure stays with the treating physician or surgical team. Dental clearance does not guarantee a medical outcome, and dental disease does not always prevent treatment.

Who sends these referrals, and why

Most clearance requests come from teams whose patients face a real risk if an untreated oral infection is carried into surgery or a period of lowered immunity.

Our dental clearance service page lists the physicians who most often ask, from orthopedic, cardiac, transplant, bariatric and neurosurgical teams to oncologists, rheumatologists, endocrinologists and primary care physicians.

The reasons differ. A joint surgeon worries about infection reaching a new implant. A cardiac team worries about bacteria reaching a heart valve. An oncology or transplant team worries about an infection flaring when the immune system is suppressed. That difference matters because it changes the question the dental office should answer.

Our short articles on conditions that may require dental clearance and how dental clearance communication with physicians works cover the basics; the sections below cover the practical details.

When a full-arch specialty team is a good fit, and when it is not

A routine clearance for a patient with healthy teeth can be done by the patient's own general dentist. A specialty team makes more sense when there are many failing teeth, extractions under sedation, a complex medical history or a patient who will need teeth replaced afterward.

A patient's regular dentist may be the fastest route to a simple "no active infection" letter. Referring to a team like ours tends to help when:

• The patient has several loose, broken or infected teeth, or advanced gum disease, and may need multiple extractions before the medical date.
• Treatment will likely need IV sedation or general anesthesia, and the patient's heart, lung, kidney or liver history makes anesthesia planning important.
• The patient has already lost most teeth, wears an ill-fitting denture, or will need a plan for eating and smiling after extractions.
• Bone loss, prior failed dental work or a sinus problem may complicate surgery.
• The patient will eventually want implants, and the medical team wants the clearance work and the long-term plan to fit together.

A specialty office is not always the right setting. A patient too medically unstable for office-based care, or already in the hospital, may be better served by a hospital dental service, and a patient who needs only a cleaning and a filling does not need a surgical team. Telling us the situation helps us say quickly whether we are the right fit.

What to send with the referral

The fastest clearances start with a complete referral packet, so nothing has to be chased later.

You do not need everything on day one. A phone call with the procedure, the date and the medication list is enough to start, and patients can bring the form to the first visit.

Word the question so the answer is useful

The clearer the question, the clearer the letter. Vague requests tend to produce vague answers.

Published hospital clearance forms tend to ask one or more of these:

1. Is there any active dental or gum infection? This is the core question for most joint, cardiac and transplant teams.
2. Has the patient had a dental exam and x-rays within a set window? One published cardiac surgery form from a large health system asks for an exam with full-mouth x-rays or a panoramic image within six months of the surgery date.
3. If treatment is needed, when will it be finished? A published cardiothoracic surgery form from another health system asks that needed treatment be completed two weeks before surgery, and asks for a new letter once it is done.
4. Is any dental treatment expected in the months after surgery? Some teams, especially in joint replacement, prefer to avoid elective dental work during early recovery and ask whether any is likely.
5. Is the patient's mouth stable for a period of immune suppression? Oncology and transplant teams often care most about sources of infection that could flare months later.

If your team has a policy, such as no elective dental work for a set period after a joint replacement, put it in the referral. If your team does not need some of these answers, say so; it keeps the visit focused and may shorten the timeline.

Some institutions exempt patients who have no natural teeth. The cardiac form mentioned above, for example, states that patients whose teeth have all been removed or who wear dentures do not need clearance for that program. Whether your team follows the same rule is up to your team, so check before the patient books.

What happens when the patient arrives

The visit starts with the medical question, the history and an exam, then imaging when the clinical team decides it is appropriate.

Our article on what happens during a dental clearance evaluation describes the visit itself. When the clinical team decides 3D imaging is appropriate, cone beam CT lets the specialists study bone volume, nerve pathways, sinus position and jaw anatomy, which can show infection around root tips and bone loss that flat images miss.

The patient then hears what was found, what needs to happen before the medical procedure, what can wait, and how long each step is likely to take. If the answer depends on a medication decision or a physician's input, that question goes to you before the plan is final.

What you get back

Expect a short letter or completed form that answers your question, and a treatment summary when treatment is involved. Records and imaging can be sent when requested and authorized.

Our clearance service provides clearance letters, treatment summaries, records and supporting documentation to physicians, surgeons, specialists and medical teams when requested and authorized by the patient. In practice, the answer usually falls into one of three groups.

No active infection found. The letter states the exam date, the provider, what was examined and imaged, and that no active dental or gum infection was found. If the form asks whether dental treatment is anticipated soon, the letter addresses that too.

Findings that need treatment first. The letter lists what was found (for example, an abscessed tooth, teeth that cannot be saved or advanced gum disease), what treatment is recommended before your procedure, and an estimated completion date. After treatment, an updated letter or treatment summary confirms what was done, on which dates, and how healing is progressing. If your form requires a new letter after treatment, tell us when you refer.

Findings that can safely wait. Not every problem needs treatment before surgery. A cavity that is not infected, or a worn crown, may be noted with a recommendation to treat it later, at a time your team considers safe. The letter should say this plainly so the surgery is not held for something that does not need to hold it.

A clearance letter is a summary for the medical team, not the full dental chart. If you need the chart notes, specific images or the imaging report, ask for them by name. If the patient will have surgery in a hospital where an anesthesia team also needs information about the mouth, such as loose teeth that could be dislodged during intubation, say so; that detail is easy to include when we know it is wanted.

The final medical decision is always made by the treating physician or medical team, not by the dental office.

Timelines: plan backward from the procedure date

When no treatment is needed, clearance can move quickly. When extractions or other treatment are needed, the timeline depends on scheduling, healing and any medication changes, so earlier referrals are better.

Count backward from the medical date:

1. The procedure date. Your team's cutoff, for example "treatment complete two weeks before surgery", sets the last day for dental work.
2. Healing time. Extraction sites, grafts and gum treatment need time to heal before many medical procedures. How much time depends on the procedure ahead and on your team's policy; our procedure-by-procedure clearance guide covers typical windows before transplant, cancer treatment, joint replacement and valve surgery.
3. Treatment visits. Oral surgery may be completed in one visit or staged over time, depending on the patient and the plan, and that choice affects the timeline. Our article on when dental treatment is recommended before medical clearance explains what that treatment usually involves.
4. Medication and anesthesia planning. If a blood thinner, diabetes medicine or other drug needs a physician's decision, or if sedation planning needs your input, build in time for that exchange.
5. The first exam. This is the step the referring office controls most. Sending the patient weeks, not days, before the surgery date leaves room for everything above.

Common causes of delay are a missing form, an unclear deadline, an unanswered medication question, no ride or helper at home after sedation, and insurance preauthorization. All are easier to solve with a few weeks of lead time.

When the timeline is tight, tell us. A minimum plan that removes sources of infection before the procedure, and leaves the rest for later, may be possible. Whether it fits a given patient is a clinical decision made after the exam.

Medication questions that may come back to you

Most medication decisions around dental surgery belong to the prescribing physician. Expect a call or a note when a change is being considered, not a change made on our own.

These are the medication groups that most often lead to a question for the referring or prescribing physician:

• Anticoagulants and antiplatelet drugs. The American Dental Association summarizes evidence that most patients on warfarin, antiplatelet drugs or the newer direct oral anticoagulants need no change before dental procedures, with bleeding controlled locally. For higher-risk patients or more extensive surgery, any change should be made on the advice of the patient's physician, and for patients with coronary stents the cardiologist should be contacted before any antiplatelet drug is stopped. Our article on dental implants with heart disease covers this for patients.
• Antibiotic prophylaxis. Under current American Heart Association guidance, as summarized by the ADA, antibiotics before certain dental procedures are reasonable only for a small group of cardiac patients, including those with prosthetic valves or valve repair material, prior infective endocarditis, certain heart transplant situations and certain congenital heart conditions. For patients with prosthetic joints, the ADA's guideline states that, in general, antibiotics are not recommended before dental procedures to prevent joint infection. When antibiotics are considered for a joint patient, the ADA says it is most appropriate for the orthopedic surgeon to recommend the regimen and, when reasonable, write the prescription.
• SGLT2 inhibitors. An American College of Cardiology review notes that the FDA recommends stopping canagliflozin, dapagliflozin and empagliflozin 3 days before scheduled surgery, and ertugliflozin at least 4 days before, because of the risk of ketoacidosis. If a patient on one of these drugs is having extractions under sedation, the prescribing physician's instructions matter.
• GLP-1 receptor agonists. Multi-society guidance released by the American Society of Anesthesiologists in 2024 says most patients can continue these drugs before elective procedures, while those at highest risk of delayed stomach emptying (early dose escalation, higher doses or stomach symptoms) may need a 24-hour liquid diet or other changes, decided together by the anesthesia provider, the proceduralist and the prescribing team. This applies to deep sedation and general anesthesia, not just hospital surgery.
• Bone-modifying drugs. Bisphosphonates and denosumab change the risk of jaw surgery, especially at cancer doses. The dose, the reason and how long the patient has taken them all matter. Our article on implants after radiation or cancer bone drugs explains the risk for patients.
• Steroids and immune-suppressing drugs. These can slow healing and raise infection risk, and timing around transplant or rheumatology treatment is usually set with the prescribing team.

We do not ask patients to stop or change any of these medications on their own. If a change is being considered, the question comes to you, and the decision is yours.

Anesthesia notes: what we need from you, and what you can ask for

When treatment needs IV sedation or general anesthesia, the anesthesia plan is built around the patient's medical history, so a few details from the referring physician help the planning.

Depending on the procedure and health history, options may include local anesthesia, IV sedation or general anesthesia, and the doctor discusses the safest and most appropriate option with the patient. In our RISE Protocol, the anesthesia provider is a separate role from the surgeon: the oral surgeon focuses on the surgery and the anesthesia provider focuses on the patient. Our Hutto office has a dentist anesthesiologist on site. Our anesthesia and patient comfort page describes monitoring of oxygen levels, breathing, heart rate and blood pressure when sedation is used, and our article on why dedicated anesthesia professionals matter explains the reasoning.

Before sedation is planned, the anesthesia provider may ask for the most recent cardiology note or testing, any sleep apnea diagnosis and CPAP use, kidney and liver function for patients with known disease, recent blood sugar control, any history of difficult airway or anesthesia reactions, and clear instructions on blood thinners, diabetes medicines and GLP-1 or SGLT2 drugs.

After treatment, you can ask for a summary that covers what was done, the type of anesthesia used, any notable events, medications prescribed at discharge, and when the patient was told to resume any held medication. If your team wants this sent automatically after treatment, say so in the referral. Our article on advanced anesthesia monitoring describes what is watched during sedation.

Sedation is not right for every patient, and no anesthesia is free of risk. A patient whose condition makes office-based sedation unsafe may need care in a hospital setting instead, and we would rather say so early.

When the teeth are failing: clearance and the long-term plan

When most of a patient's teeth are failing, the clearance work and the tooth-replacement plan should be planned together, with the medical procedure coming first.

Some referred patients have one bad tooth. Others have many failing teeth, and treating one tooth at a time can leave the problem in place. Our short article on full-mouth rehabilitation before medical procedures describes how a more organized plan works.

In practice, the plan often splits in two: removing sources of infection before the medical procedure, with a way to eat and smile while healing, and replacing teeth for the long term once the medical team says elective dental care is safe. Both of our offices offer traditional dentures, snap-on implant overdentures and fixed full-arch teeth. For selected patients with severe upper bone loss, Dr. Dan Holtzclaw and Dr. Enrique Tabarini perform zygomatic and pterygoid implants. Not every patient is a candidate for implants, and the right choice can change after a major medical event.

Under our RISE Protocol, a prosthodontist plans the bite and final teeth before surgery, the digital planning team studies the anatomy, the oral surgeon and anesthesia provider handle the surgical phase, and dental technicians shape the teeth with support from our in-house lab at the Katy office. For a referring physician, the benefit is that clearance extractions are planned with later tooth replacement in mind. Whether implants can be placed at the same surgery as the extractions, before a medical procedure, is decided case by case with the medical team.

If the patient has a long-standing infection, our article on chronic tooth infection and dental implants may help them understand the plan.

Sharing records and protecting privacy

Records can move between dental and medical teams for treatment purposes, and our practice sends clearance documentation when it is requested and authorized.

HHS guidance under the HIPAA Privacy Rule states that health care providers may share health information such as x-rays, lab reports and diagnoses with other providers for treatment purposes, including referrals and consultations, without the patient's written authorization, using reasonable safeguards. Our practice provides clearance letters and records when they are requested and authorized, so the patient's wishes about who receives what still matter. A signed release, plus a confirmed fax number or secure address for your office, keeps the letter from going to the wrong place. If your team receives letters a specific way, such as a particular fax line or portal, include it with the referral.

Insurance and documentation

Physician notes can matter for the medical-insurance side of dental surgery, but coverage depends on the plan, and it is worth checking early rather than assuming.

When dental surgery is tied to a medical procedure, some medical plans will review part of it. At our offices, medical insurance is reviewed only for surgical professional services, such as extractions, bone grafting and alveoloplasty. Implants, temporary teeth and the final prosthesis are billed to the patient separately. Only PPO plans work for our out-of-network oral surgery benefits, and we cannot bill Federal Employee Program (FEP) Blue Cross Blue Shield plans. If the patient has a PPO plan with oral surgery coverage, a medical claim for the surgical part is worth checking, but please verify with the plan before treatment; coverage is never guaranteed.

What helps on the documentation side is a clear record of why the dental treatment is needed for the medical care: the referral itself, the planned procedure and the physician's note explaining the concern. Through Insurance Advantage, our team reviews dental and medical benefits when appropriate. Our article on medical insurance for the oral surgery part of full-arch treatment explains how those claims work. Financing through third-party partners may be available to qualified patients, subject to approval.

How our Katy office works with Houston-area physicians

Our Houston-area office is in Katy and serves patients referred from across Greater Houston. Referrals can start with a phone call to (832) 632-7037.

Our office is at 707 S Fry Rd, Suite 150, Katy, TX 77450, and sees patients from Katy, Houston, Cypress, Sugar Land, Richmond, Fulshear, the Memorial area and the rest of the region. We do not have offices in those other cities; our two offices are in Katy and Hutto. The Katy location page has directions, and our full-mouth dental implants in Katy page explains the full-arch side of the practice for patients who end up needing it.

What referring offices can expect from our practice:

• A clinical team that includes oral surgeons and a prosthodontist, so surgical findings and the long-term restorative plan are considered together
• Imaging when the clinical team decides it is appropriate
• Oral surgery services such as extractions, bone grafting and alveoloplasty, listed on our oral surgery page
• An anesthesia plan built around the patient's medical history, with physician input when it is needed
• Written documentation for your team when requested and authorized
• Our in-house dental lab at the Katy office, for patients who go on to tooth replacement

After full-arch treatment, long-term care runs through a required maintenance program rather than a traditional warranty; our implant warranty page explains why. That matters for medical teams who want to know a patient will be seen regularly after surgery, for example after a joint replacement or transplant.

A one-page referral checklist

Before the patient calls or arrives, it helps to have:

1. The clearance form, or the exact wording your team needs
2. The procedure and date, plus the latest date dental treatment can be completed
3. The question: active infection only, or also expected dental needs after surgery
4. A current medication list, with any instructions you already have about blood thinners, diabetes medicines, SGLT2 or GLP-1 drugs
5. Key diagnoses, cardiac history and devices, allergies and any anesthesia history
6. Recent labs relevant to bleeding, healing or sedation, if available
7. Your contact name, phone and secure fax or portal for the reply
8. Whether you want a treatment summary or anesthesia summary after treatment

Frequently asked questions

What should a referring physician send for a dental clearance?

Send the clearance form or the wording you need, the planned procedure and date, the specific question you need answered, a current medication list, relevant diagnoses and devices, and a contact for the reply. A phone call with the procedure, date and medication list is enough to start; the rest can follow.

What does a dental clearance letter usually include?

It usually includes the exam date, the dental provider's contact information, what was examined and imaged, whether active infection was found, any treatment completed with dates, any treatment still recommended and when, and any dental reason to wait. It is a summary for the medical team, not the full chart. The decision to proceed stays with the treating physician.

How long does dental clearance take?

If no treatment is needed, the letter can follow the exam quickly. If extractions or gum treatment are needed, the timeline depends on scheduling, healing time and any medication decisions. Many surgical teams want treatment finished a set number of weeks before surgery, so referring weeks ahead of the date gives the most room.

Should patients stop blood thinners before dental extractions?

Usually not without a physician's direction. The American Dental Association summarizes evidence that most patients on warfarin, antiplatelet drugs or newer oral anticoagulants do not need changes for dental procedures, with bleeding controlled locally. For higher-risk patients or more extensive surgery, any change should be made by the prescribing physician.

Can a patient with failing teeth be cleared and still plan for implants later?

Often, yes. Many plans remove sources of infection before the medical procedure and leave tooth replacement for later, once the medical team says elective dental care is safe. Options include dentures, snap-on implant overdentures and fixed full-arch teeth. Implant candidacy depends on health, bone and timing, and not every patient qualifies.

Refer a patient or ask a question

If you have a patient who needs dental clearance before a medical procedure, or whose failing teeth need a plan that fits around their medical care, call our team at (832) 632-7037 with the procedure, the date and the medication list. Patients can also schedule a consultation or book directly with our Katy office.
