What Happens to Your Dental Health When You Take Ozempic

The term “Ozempic teeth” has been circulating on social media because some GLP-1 users have noticed a troubling change: bleeding gums and general oral discomfort. Research hasn’t confirmed a direct link, but dentists note that common side effects of GLP-1s can cause dental problems.

1. Dry Mouth

One of the most common complaints among Ozempic users is dry mouth, or xerostomia, a side effect that can damage teeth and gums, according to Sandip Sachar, DDS, a general and cosmetic dentist at Sachar Dental NYC.

GLP-1 medications reduce appetite by slowing stomach emptying, said Sachar. That slowed digestion can also suppress thirst, reducing water and food intake, which accounts for some hydration, and can lead to dry mouth.

Without enough saliva, your mouth loses one of its most critical protective tools. Saliva neutralizes acids and flushes out bacteria, said Sachar.

“When you have less saliva, you are more prone to cavities, as saliva is one way the body helps clean debris off teeth,” said Meghan Garcia-Webb, MD, a triple board-certified internal medicine, lifestyle medicine, and obesity medicine doctor at Beth Israel Deaconess Medical Center.

Other symptoms of dry mouth include:

• Increased tooth sensitivity to hot and cold
• Enamel erosion
• Tooth fractures
• Receding gums
• Generalized oral discomfort

2. Acid Reflux

Alongside dry mouth, acid reflux is a common Ozempic side effect that can indirectly damage your teeth, said Garcia-Webb.

Acid reflux, also known as heartburn, occurs when stomach acid rises into your esophagus.

“If stomach acid makes it up to the mouth, this can be very irritating to the mucosal surfaces and damaging to the enamel that helps protect teeth,” said Garcia-Webb.

“This can, in turn, weaken tooth structure and increase tooth sensitivity,” putting you at higher risk for cavities and decay,” she added.

3. Bad Breath

Ozempic-related acid reflux and dry mouth can also work together to create another unpleasant side effect—bad breath. 

Sachar said that when the body produces less saliva, as is often the case with dry mouth, it loses one of its key defenses against odor-causing bacteria.

On top of that, acid reflux can worsen the situation. Stomach acid that rises into the mouth can leave a sour or metallic taste and distinct odor behind.

4. Irritated Gums

Dry mouth also reduces the saliva’s natural ability to protect the gums. Over time, this lack of protection can contribute to receding gums and irritation, said Sachar.

Acid reflux can likewise aggravate gum tissue. Stomach acid in the mouth can erode enamel and irritate the mouth’s soft tissues.

This leaves you at greater risk for gingivitis, an early stage of gum disease, though it’s important to note that research hasn’t confirmed a direct link between Ozempic and gum disease, said Sachar.

What You Can Do to Protect Your Teeth

“In my practice, GLP-1 medications play a relatively small contribution compared to other causes of oral problems,” said Sachar. “But it is still important to recognize symptoms and prevent long-term complications of tooth decay or worse.”

If you’re experiencing tooth sensitivity, Sachar recommends a proactive approach to oral care.

That includes:

• Maintaining good oral hygiene: Brush your teeth twice daily with fluoride toothpaste and floss daily.
• Staying hydrated: Drink water throughout the day to stay consistently well-hydrated, even if you don’t feel thirsty.
• Chewing sugar-free gum: This stimulates saliva production without further damaging teeth.
• Avoiding sugary, acidic, and sticky foods or drinks: Soda, candy, and other sugary or acidic snacks can cling to teeth and wear down enamel.
• Talking to your doctor: Alert your doctor immediately if you have persistent acid reflux or vomiting, as they can prescribe medication to control these side effects and prevent dental damage.
• Scheduling more frequent dental cleanings: If you’re experiencing symptoms like sensitivity, bad breath, or bleeding gums, visit your dentist to get ahead of larger oral health issues.
