If you or someone you know is on Ozempic, Wegovy, Mounjaro or another GLP-1 medication, you have probably seen the phrase "Ozempic teeth" pop up on social media. The videos make it sound like these drugs are wrecking people's smiles. The reality is more nuanced, and a lot less scary, than the headlines suggest. GLP-1 medications are now part of everyday life for many Canadians. A 2026 Leger survey on GLP-1 medication use estimated that around three million Canadian adults are taking them. So it makes sense that patients in Newmarket and across York Region are asking their dentists what these drugs mean for their teeth and gums.

Key Takeaways

• "Ozempic teeth" is a social media term, not an official dental diagnosis.
• There is currently no strong evidence that GLP-1 medications directly damage healthy teeth.
• Side effects like dry mouth, nausea, vomiting and reflux can raise your risk of cavities and enamel erosion.
• Staying hydrated, using fluoride and rinsing after vomiting make a real difference.
• Always tell your dentist about every medication you take, including GLP-1 drugs.

What Is "Ozempic Teeth," Really?

The term grew out of the same online trend as "Ozempic face," which describes facial changes after rapid weight loss. People began sharing stories of cavities, sensitivity or worn enamel after starting a GLP-1 drug and connected the two. Dentists point out that "Ozempic teeth" isn't a recognized condition, and current research hasn't shown that semaglutide or similar drugs attack tooth enamel on their own. Researchers are still studying how these medications affect the mouth, and Oral Health Group has covered early research into Ozempic and oral health for Canadian dental professionals. What the evidence does support is that some common side effects of these drugs can create conditions where dental problems are more likely.

How GLP-1 Side Effects Can Affect Your Mouth

Dry Mouth

GLP-1 drugs reduce appetite, and many people end up eating and drinking less overall. Less fluid can mean less saliva. Saliva is your mouth's natural defence system. It washes away food particles, neutralizes acids and delivers minerals that help repair early enamel damage. When your mouth is dry for long stretches, bacteria have an easier time causing cavities and gum irritation.

Nausea, Vomiting and Acid Reflux

Nausea and vomiting are among the most common side effects, especially when starting a GLP-1 medication or increasing the dose. Some people also experience heartburn or reflux. Stomach acid is very strong, and repeated exposure can slowly soften and wear away enamel, a process called acid erosion. Erosion often shows up as sensitivity to hot or cold, teeth that look more yellow (as the thinner enamel lets the dentin show through), or edges that look slightly see-through. Our guide to tooth enamel loss prevention explains why enamel doesn't grow back once it's gone.

Changes in Eating Habits

Some people on GLP-1 drugs eat small amounts throughout the day instead of regular meals, or sip on sports drinks and juices to stay energized. Frequent snacking and sugary or acidic drinks keep your teeth under constant attack, even if your overall food intake has dropped.

Simple Ways to Protect Your Teeth While on a GLP-1

The good news is that a few small changes go a long way:

• Drink water regularly. Keep a bottle nearby and sip throughout the day, even if you don't feel thirsty.
• Chew sugar-free gum. Gum with xylitol stimulates saliva and helps with dry mouth.
• Rinse, don't brush, right after vomiting. Swish with water or a mix of water and a little baking soda, then wait about 30 minutes before brushing so you don't scrub softened enamel.
• Use fluoride toothpaste twice a day. Fluoride helps strengthen enamel against acid. Your dentist may also suggest a fluoride rinse or in-office varnish.
• Limit sipping on sugary or acidic drinks. If you need an electrolyte drink, choose a sugar-free option and drink it with a meal.
• Brush gently with a soft brush. Hard scrubbing can make erosion worse. Here are common brushing mistakes to avoid.

What to Tell Your Dentist

Your dentist can only spot medication-related risks if they know what you're taking. At your next visit, mention:

• The name of your GLP-1 medication and when you started it
• Any nausea, vomiting or reflux you've had
• Whether your mouth feels dry, especially at night
• New sensitivity, sore gums or changes in how your teeth look

This matters for more than cavity risk. Because these medications slow down how quickly your stomach empties, your dentist and medical team may want to know about them before sedation or certain procedures. Being upfront helps them plan your care safely. If you've noticed changes, don't wait for your next routine cleaning. Early erosion and small cavities are much easier and cheaper to fix than advanced damage. You can find a dentist in Newmarket through our directory and book a check-up.

Frequently Asked Questions

Does Ozempic directly damage teeth?

Current evidence doesn't show that GLP-1 drugs directly damage healthy teeth. Problems that people link to these drugs are usually tied to side effects like dry mouth, vomiting or reflux, which can be managed.

Should I stop my medication if I'm worried about my teeth?

No. Don't stop or change any prescription without talking to your doctor. In most cases, simple oral care habits are enough to protect your teeth while you continue treatment.

Can a dentist repair enamel erosion?

Enamel doesn't regrow, but dentists can protect and restore affected teeth with fluoride treatments, bonding, fillings or crowns, depending on how much damage there is.

The Bottom Line

"Ozempic teeth" makes for a catchy headline, but it isn't a diagnosis, and there's no strong proof that GLP-1 medications harm healthy teeth on their own. The real risks come from side effects you can manage with water, fluoride, gentle brushing and smart rinsing. Keep your dentist in the loop about your medications, and if something feels off, get it checked early. Search our Newmarket dentist directory to find a dental office near you.
