Does Suboxone damage your teeth, and what can you do about it?

Yes, Suboxone — a medication for opioid use disorder — can damage your teeth, but you don't have to choose between recovery and oral health. Its active ingredient, buprenorphine, dissolves in your mouth and exposes your teeth to acid while reducing protective saliva, which can lead to decay, cavities and tooth loss. The FDA has warned about this risk since 2022.¹ With the right care, much of this damage can be prevented or treated.

What you'll learn in this article:

• Suboxone can damage your teeth in two ways: it exposes them to acid while it dissolves and reduces the saliva that helps protect your enamel.

• Rinsing your mouth with water right after each dose is one of the simplest and most effective ways to help protect your teeth.

• Tooth sensitivity, persistent dry mouth and small white or brown spots on your teeth are early warning signs that shouldn't be ignored.

• You don't need to stop taking Suboxone to protect your teeth. With the right care, you can manage your oral health while staying on your recovery plan.

If you're taking Suboxone and haven't seen a dental provider recently, schedule an appointment with your Aspen Dental provider to evaluate your oral health and build a prevention plan that works alongside your treatment.

What is Suboxone and how does it affect your teeth?

Suboxone is taken by dissolving it under your tongue or against your cheek, which usually takes 15 to 30 minutes — long enough for the medication to stay in direct contact with your teeth and gums.

It affects your teeth in two ways. First, Suboxone is acidic, and repeated exposure gradually wears away tooth enamel (the hard outer layer that protects your teeth). Once enamel is lost, it can't grow back, making your teeth more vulnerable to tooth decay.

Second, buprenorphine can reduce saliva production. Saliva does more than keep your mouth moist; it helps neutralize acids, wash away bacteria and repair early enamel damage. When saliva levels drop, bacteria grow more easily and acid stays on your teeth longer, which can speed up decay.²

What kinds of dental problems can Suboxone cause?

Suboxone-related dental damage tends to follow a few common patterns, from rapid cavities to increased sensitivity and weakened enamel.

Why am I getting so many cavities so quickly?

People taking sublingual Suboxone face a meaningfully higher risk of cavities and tooth loss than those on other OUD medications — more than 1.5 times higher, according to one large study.³ The acidic oral environment and reduced saliva allow decay to progress much faster than it would under normal conditions, often within months of starting the medication.

Why are my teeth suddenly so sensitive?

Sensitivity to cold, heat or sweet foods often signals early enamel loss. As enamel thins, the inner layers of the tooth respond more easily to temperature and pressure changes. Addressing sensitivity early, before a cavity develops, leads to simpler treatment.

Can Suboxone cause teeth to crack or break?

Weakened enamel is more brittle. Some patients notice chips or small fractures while chewing ordinary food. This is a sign that tooth structure has been compromised and should be evaluated as soon as possible.

Steps you can take to protect your teeth

You don't need to stop taking Suboxone to protect your oral health. These easy-to-adopt habits make a real difference.

Rinse with water after each dose

Once your film or tablet has fully dissolved, swish water around your mouth for 30 to 60 seconds and spit. This clears residual medication and reduces the acidity lingering on your teeth.

Wait before brushing

Enamel softened by acid is temporarily more vulnerable to abrasion. Wait at least 30 minutes after your dose before brushing, as brushing sooner can cause additional wear.

Sip water throughout the day

Staying hydrated helps compensate for reduced saliva and keeps your mouth from becoming too dry between doses.

Use fluoride toothpaste

Fluoride strengthens enamel and slows decay. Brush twice daily and consider a fluoride rinse before bed for added protection.

Try sugar-free gum with xylitol

Chewing gum stimulates saliva flow. Xylitol also helps reduce the bacteria responsible for cavities.

See your dental provider regularly

Early-stage problems are far easier to treat than those that have advanced. Let your provider know you're taking Suboxone. It helps them monitor the areas most likely to be affected and tailor their approach to your care.

Can Suboxone-related dental damage be treated?

Yes. Most dental problems linked to Suboxone can be treated, and the sooner they're found, the simpler treatment usually is.

Fillings can repair early cavities. Crowns can restore and protect teeth that have lost a lot of structure. If gum disease has developed, a deep cleaning may help bring it under control. A dental provider can evaluate your oral health and recommend the treatment that's right for you.

One thing is especially important: don't stop taking Suboxone without medical guidance. It's not necessary to protect your teeth, and stopping the medication on your own can be dangerous. Talk to your prescribing provider before making any changes. With the right care, you can protect both your oral health and your recovery.

If you're taking Suboxone, your dental provider can evaluate your teeth for early signs of damage, recommend ways to protect your smile and treat problems before they become more serious.

Does Suboxone damage your teeth, and what can you do about it? FAQs

If you're still wondering how Suboxone affects your teeth or what you can do to protect them, these answers cover some of the questions patients ask most often.

Should I brush my teeth before or after taking Suboxone?

Brush before your dose, not immediately after. Brushing before taking Suboxone cleans your teeth without disturbing temporarily softened enamel. After your film or tablet fully dissolves, rinse your mouth with water and wait at least 30 minutes before brushing again. This timing protects your enamel at both points in your routine.

Do I need to tell my dental provider I'm taking Suboxone?

Yes, this is a genuinely important detail to divulge. Knowing you're on Suboxone helps your dental provider recognize patterns of decay, sensitivity or gum changes that are consistent with the medication's effects. It also allows your dental provider to customize your prevention plan and monitor the right areas at each visit. Your dental provider's focus is your oral health — there's no need to hesitate.

Will my teeth get better if I stop taking Suboxone?

Stopping Suboxone is not necessary (or recommended) to improve your dental health. Some damage, like active cavities or gum inflammation, can be treated and halted with the right care. However, enamel that has already worn away cannot grow back, which is why early intervention matters.

The more important step is telling your dental provider you're taking Suboxone so they can build a prevention plan and catch problems before they progress. Any decision about your medication should always be made with your prescribing provider — not based on concerns about your teeth.
