Most people who start Suboxone are focused on the big things: steadier days, fewer cravings, and a safer path forward. Teeth are rarely on the list. Then a dental warning appears in a pharmacy leaflet, a friend mentions a cracked tooth, or a dentist asks a question that makes you wonder what you should be doing differently.
The questions that follow are practical ones. Should I rinse after a dose? Should I brush right away or wait? Do I need to see a dentist? Does this mean I should stop? This guide answers those questions using what regulators have said about dental problems with medicines like Suboxone, and it breaks the topic into simple routines you can actually follow.
This article is general education, not personal medical or dental advice. It does not give buprenorphine doses. Do not stop or change Suboxone on your own. Stopping suddenly can cause withdrawal and serious setbacks. Bring any concerns to your prescriber and your dentist.
Key Takeaways
- In January 2022, the U.S. FDA warned that buprenorphine medicines dissolved in the mouth, including sublingual tablets and films used for opioid use disorder, have been linked to dental problems such as cavities, tooth decay, oral infections, and tooth loss.
- The FDA still considers these medicines an important treatment, and states that the benefits clearly outweigh the risks.
- Recommended steps include: let the medicine dissolve completely, then gently rinse with water and swallow, and wait at least 1 hour before brushing.
- See a dentist soon after starting treatment, tell them you take buprenorphine, and keep up regular checkups.
- Do not stop Suboxone because of a dental concern without speaking to your prescriber first.

What the FDA Actually Said
On January 12, 2022, the U.S. Food and Drug Administration issued a Drug Safety Communication about dental problems reported with buprenorphine-containing medicines that dissolve in the mouth. These include tablets and films placed under the tongue or against the inside of the cheek. Suboxone, which combines buprenorphine with naloxone, is one of the best-known examples, and similar sublingual tablets and generic films are covered by the same warning.
The key points, in plain language
- The problems. Reported issues include tooth decay, cavities, oral infections, and loss of teeth. They have been reported even in people with no previous history of dental problems.
- The numbers. The FDA reviewed its adverse event reports and medical literature and identified 305 cases of dental problems, 131 of them classified as serious. Because these come from voluntary reports, the FDA said it cannot determine how likely any one person is to experience them.
- The timing. Some cases appeared as soon as two weeks after treatment began, though the median time to diagnosis was about two years.
- The outcomes. The most common treatment reported was tooth extraction. Others required root canals, crowns, implants, or other dental surgery.
- The balance. The agency stressed that buprenorphine remains an important treatment for opioid use disorder, and that the benefits clearly outweigh the risks.
- The new requirement. A warning about dental problems was required to be added to the prescribing information and the patient Medication Guide for these products.
What the FDA recommended for patients
- Continue taking your medicine as prescribed. Do not suddenly stop without talking to your health professional.
- After the medicine has completely dissolved, take a large sip of water, swish it gently around your teeth and gums, and swallow.
- Wait at least 1 hour before brushing your teeth.
- Schedule a dentist visit soon after starting treatment, tell your dentist you take buprenorphine, and keep up regular checkups.
- Tell your prescriber about any history of tooth problems, including cavities.
- Report side effects to the FDA’s MedWatch program.

Why Teeth May Be Affected (and What Is Still Unknown)
It is natural to want a clear cause. At present, the honest answer is that researchers do not have a complete explanation. The FDA based its warning on reports and published cases, not on a settled mechanism. Several factors have been discussed in the clinical literature as possible contributors. None of them should be presented as proven, and more than one may play a part.
Possible contributors people discuss
- Contact time. Sublingual and buccal products sit in the mouth while they dissolve, so teeth, gums, and the lining of the mouth are exposed to the medicine and its additives for a period of minutes.
- Reduced saliva. Saliva protects teeth by washing away food and bacteria and neutralizing acids. Opioids as a group are associated with dry mouth, and less saliva makes cavities more likely.
- Acidity in the mouth. Some researchers have suggested that dissolving products may make the mouth more acidic for a time, which could soften enamel. This is one reason for the advice to wait before brushing, which is explained below.
- Sugar and snacking. Cravings for sweets and changes in eating habits are common in many life situations, including recovery, and frequent sugar exposure raises cavity risk.
- Existing dental neglect. Many people entering treatment have gone a long time without dental care, so decay may already be present and progress faster.
- Other substances and medicines. Past or current use of other drugs, tobacco, alcohol, and medicines that dry the mouth can all add to risk.
The practical point: you do not need to wait for science to settle before protecting your teeth. The recommended steps are inexpensive, simple, and reasonable regardless of the exact cause.
A Mouth Timeline: Following One Dose From Start to Finish
It helps to picture a single dose as a short sequence. Your own product label has the exact instructions, and your prescriber or pharmacist can clarify anything that is unclear. This is a general illustration built on the FDA’s advice and common label directions.
| Stage | What is happening | What to keep in mind |
|---|---|---|
| Before the dose | You prepare to place the tablet or film. | Follow your label. Some film instructions advise moistening the inside of the mouth with water first. Do not eat or drink during the dissolving period. |
| During the dose | The medicine dissolves and is absorbed through the lining of the mouth. | Do not chew, swallow, move, or cut the product, since that can change how much is absorbed. Avoid talking, eating, or drinking until it has dissolved. |
| Right after it dissolves | Residue and a changed mouth environment remain. | This is when the FDA advice applies: take a large sip of water, swish gently around the teeth and gums, then swallow. |
| The next 60 minutes | Saliva gradually restores the mouth to its normal state. | Hold off on brushing. Brushing sooner may harm enamel that is temporarily softened, according to the FDA’s reasoning. |
| After one hour | The mouth has had time to recover. | You can brush with fluoride toothpaste, then keep up with flossing and other oral care. |
Why not rinse before the medicine dissolves?
Rinsing too early could wash away medicine before it is fully absorbed, which is why the advice is specific: wait until it has completely dissolved. If you are unsure whether something is fully dissolved, ask your pharmacist what to look for with your specific product.
Why swallow the rinse water?
The FDA’s wording is to rinse and then swallow. Plain water is harmless, and swallowing means you are not spitting out residual medicine that may still be absorbing. Follow the exact wording on your Medication Guide.
The Rinse-and-Brush Decision Guide
Real life does not always match the ideal routine. The following scenarios cover common situations. Where your own label or clinician gives different instructions, follow theirs.
| Situation | A sensible approach based on the FDA advice |
|---|---|
| “My dose just dissolved. What now?” | Take a large sip of water, swish gently, swallow. Do not brush yet. |
| “When can I brush?” | At least 1 hour after the dose. |
| “I always brush right after my morning dose.” | Consider shifting your order. Brush first thing, take your dose, rinse, and then wait an hour before any more brushing. Many people find brushing before dosing easier to remember. Check with your dentist if you want a routine tailored to you. |
| “I have a bedtime dose.” | Plan your last brushing of the day so that it fits the rule. For example, brush, take the dose, rinse, and avoid brushing again for an hour, then go to bed without eating or drinking anything sugary. Ask your dentist to help with timing if this is tricky. |
| “I take more than one dose per day.” | The rinse-and-wait approach applies after each dose. Ask your clinician or pharmacist how to organize this practically. |
| “I forgot to rinse.” | Do it as soon as you remember, once the medicine is dissolved, and keep going with the routine next time. One missed rinse is not a reason for panic. |
| “I brushed within the hour by mistake.” | Do not worry about a single occurrence. Return to the routine and mention it to your dentist if you are concerned. |
| “Can I use mouthwash?” | Plain water is what the FDA specified for the post-dose rinse. If you want to use a fluoride or other mouthwash, ask your dentist which type and when. Some contain alcohol, which can dry the mouth. |
| “Can I chew gum afterwards?” | Sugar-free gum can stimulate saliva, but check timing with your dentist or pharmacist. Avoid sugary gum. |
Building a Daily Routine Around Your Doses
The best routine is one you can keep doing. Here are building blocks you can mix and match, ideally after talking to your dentist.
The core habits
- Rinse and swallow after each dose, once it has completely dissolved.
- Wait an hour before brushing. A phone timer helps.
- Brush twice a day with fluoride toothpaste. Fluoride strengthens enamel and is a cornerstone of cavity prevention.
- Clean between your teeth daily using floss or interdental brushes.
- Keep dental appointments. Regular checkups catch small cavities before they become large ones.
Habits that support saliva and enamel
- Sip water through the day. It helps keep the mouth moist.
- Limit frequent sugary snacks and drinks. It is the frequency of sugar exposure, not only the amount, that feeds cavity-causing bacteria. Sodas, energy drinks, sweet coffees, and sticky candies are common culprits.
- Be careful with acidic drinks. Frequent sips of acidic beverages can wear enamel.
- Avoid tobacco and vaping products where you can. They raise the risk of gum disease and dry mouth.
- Limit alcohol, which can dry the mouth and irritate gums.
- Ask about extra protection. Dentists may suggest prescription-strength fluoride toothpaste, fluoride varnish at visits, or saliva substitutes for dry mouth. These are individual decisions.
A simple one-line tracker
If you find the routine hard to remember, try a note on your phone or a sticky note by the bathroom mirror: “Dissolve, rinse, swallow, wait one hour, then brush.” A short phrase is easier to follow when you are tired, rushed, or having a rough day.
Getting the Most From Your Dentist Visit
The FDA recommends that people starting transmucosal buprenorphine see a dentist soon after starting treatment, and that dentists perform a baseline evaluation, assess cavity risk, build a prevention plan, and encourage regular checkups. If you have not seen a dentist in years, this may feel daunting. It does not have to be.
Telling your dentist
Many people worry about being judged. Dental professionals treat patients in recovery all the time, and the information you give helps them protect your teeth. A simple opening line works well:
“I take Suboxone as a film (or tablet) dissolved in my mouth for opioid use disorder. I know the FDA recommends a dental baseline and a cavity prevention plan, and I would like help with that.”
What to share
- The product you use and how often
- How long you have taken it
- Your rinse and brush routine, so they can suggest adjustments
- Any dry mouth, sensitivity, pain, or gum bleeding
- Other medicines, since many cause dry mouth
- Past dental problems and when you last had a checkup
Questions worth asking
- What is my cavity risk, and how often should I come in?
- Would prescription-strength fluoride or a varnish help me?
- Do you recommend any products for dry mouth?
- How should I fit brushing around my doses?
- If I need treatment, how will you coordinate with my prescriber?
If cost or access is a barrier
Dental care can be expensive and hard to reach. Ask your treatment program or prescriber whether they can refer you to community clinics, dental schools, or sliding-scale services. Many areas have low-cost options, and some programs partner directly with dental providers.
Dental Pain, Procedures, and Suboxone
Dental problems can be painful, and pain management for someone on buprenorphine needs thoughtful planning. Here are the main principles, which you should always confirm with your own team.
- Do not stop Suboxone on your own before a dental procedure. Stopping suddenly can cause withdrawal and raises the risk of relapse. Any change should be planned with your prescriber.
- Tell the dentist you take buprenorphine before any procedure, and make sure your prescriber and dentist can talk to each other if needed.
- Non-opioid pain relief is commonly the first approach for dental pain, such as certain anti-inflammatory medicines, subject to your health history. Ask the dentist and your prescriber what is suitable for you.
- Local anesthetics are generally used as normal in dental care.
- If an additional opioid is being considered, it requires special coordination, because buprenorphine occupies opioid receptors and affects how other opioids work. Do not take leftover or borrowed pain medicine.
- Report severe or worsening pain promptly, since untreated dental infections can spread.
What About Other Forms of Buprenorphine?
The FDA’s warning concerned buprenorphine medicines that dissolve in the mouth. In its communication, the agency noted that there are buprenorphine products delivered by other routes, such as a skin patch and injection, and that it had not identified a dental concern for those other forms.
That is useful context, but it does not mean you should switch on your own. The choice of buprenorphine product depends on many things: your treatment goals, your history, how stable you are, practical issues like access and cost, and your preferences. If dental problems are a real worry, you can raise it with your prescriber and ask whether another form might suit you. That is a conversation to have, not a change to make unilaterally.
Dry Mouth and Its Overlap With Other Medicines
Dry mouth is one of the most important dental risk factors, and many medicines contribute. If you take Suboxone together with other drugs that dry the mouth, the effect may add up. Common culprits include some antidepressants, antihistamines, certain blood pressure medicines, and ADHD stimulants.
If you take a stimulant for ADHD, our articles on Adderall and dry mouth and Concerta and dry mouth explain the issue in more detail and offer practical ideas. If you are on methadone rather than buprenorphine, see our guide to methadone and QT prolongation, which covers a different safety topic with a monitoring plan of its own.
Signs of dry mouth
- A sticky, dry feeling in the mouth or throat
- Trouble chewing, swallowing, or speaking
- A burning sensation on the tongue
- Cracked lips or sore mouth corners
- Bad breath that does not go away
- A need to sip water frequently, especially at night
Tell your dentist if you notice these. There are many things they can suggest, from salivary stimulants to protective products.
Warning Signs to Act On
Contact your dentist soon if you notice:
- New tooth sensitivity to hot, cold, or sweet foods
- Brown, black, or white spots on teeth
- A chipped, cracked, or crumbling tooth
- Gums that bleed, swell, or pull away from teeth
- Persistent bad taste or bad breath
- A lost filling or crown
- Pain when biting
Seek urgent care if you have:
- Facial swelling, especially spreading toward the eye or neck
- Fever with dental pain
- Difficulty swallowing or breathing
- Pus or a pimple-like bump on the gum
- Pain that is severe or rapidly worsening
A dental abscess is an infection that can spread, so facial swelling and fever should never be ignored. If swelling affects breathing or swallowing, call emergency services.
Reporting side effects
The FDA encourages patients and health professionals to report side effects involving buprenorphine through its MedWatch program. Your pharmacist or dentist can help you submit a report.
Myths and Misunderstandings
- Myth: “Suboxone destroys your teeth, so it is not worth taking.” The FDA has stated that the benefits of buprenorphine clearly outweigh the risks, and the agency recommends continuing treatment while taking dental precautions. Dental problems can usually be prevented or treated, whereas opioid use disorder carries risks to life.
- Myth: “If I brush harder and sooner, I will wash it all away.” The advice is the opposite: rinse gently with water and wait an hour before brushing.
- Myth: “Only people with bad teeth are affected.” The FDA noted cases in people with no previous dental history.
- Myth: “It takes years to show, so I have time.” The typical diagnosis was around two years in, but some cases appeared within weeks. Early dental contact helps.
- Myth: “The injection has the same problem.” The FDA stated it had not identified a dental concern for non-dissolving forms such as injections and patches, but that is a topic to discuss with your prescriber, not a reason to change medicine independently.
- Myth: “A dentist will judge me or refuse to treat me.” Dentists see patients in recovery regularly, and honest information helps them care for you.
Frequently Asked Questions
Should I rinse my mouth after Suboxone?
The FDA advises that once the medicine has completely dissolved, you take a large sip of water, swish gently around your teeth and gums, and swallow it.
How long should I wait to brush my teeth after Suboxone?
At least 1 hour, according to the FDA. This gives your mouth time to return to its natural state and avoids brushing teeth that may be temporarily vulnerable.
Can I brush before taking Suboxone?
Yes, many people brush first and then take their dose, which can fit the routine more easily. Ask your dentist to confirm a schedule that suits you.
Does Suboxone cause cavities in everyone?
No. The FDA could not determine how likely any person is to be affected. The warning exists because serious problems have been reported, even in people without prior dental issues.
Should I see a dentist if I just started Suboxone?
The FDA recommends scheduling a dental visit soon after starting, telling the dentist you take buprenorphine, and keeping regular checkups.
Is it safe to take Suboxone while having dental work?
Usually treatment is continued, but plans should be coordinated between your dentist and prescriber. Do not stop or skip doses on your own.
Do I need special toothpaste?
Fluoride toothpaste is the standard recommendation. Whether you need a prescription-strength product is a decision for your dentist based on your cavity risk.
Where can I get help finding treatment or dental care?
In the United States, the SAMHSA National Helpline offers free, confidential referral information for substance use treatment. Ask your treatment provider about local dental referral options as well.
Putting It All Together
The dental warning about Suboxone and similar medicines is real, and it deserves attention. It also comes with a reassuring message from the FDA: these medicines remain an important treatment with benefits that clearly outweigh the risks, and simple habits can help protect your teeth. Let the medicine dissolve completely, rinse gently with water and swallow, wait at least an hour before brushing, use fluoride toothpaste, keep sugar frequency down, and see a dentist early and regularly.
If you take Suboxone and have not seen a dentist since starting, a good next step is to book a checkup and share this article’s talking points. If you have dental pain or swelling, do not wait. For more guides on medicines and everyday safety, browse our health blog.
