Do GLP-1 peptides damage teeth?

Not directly. The peptide doesn't attack teeth. The conditions around it can.

THE CASCADE

The American Dental Association's October 2025 guidance for patients on these peptides spells out the cascade: GI side effects (nausea, vomiting, reflux) lower the pH inside the mouth, and lower oral pH eats at tooth enamel.

Saliva normally buffers the acid; when saliva drops, the defense drops with it. So the path is peptide → GI side effects → low oral pH → enamel erosion.

THE FRAMING

The "Ozempic teeth" framing names a real cluster of dental problems, but with the wrong cause. The dentist-facing literature treats the issue as preventable through routine dental care and attention to reflux.

There isn't a peptide-specific dental mechanism in the evidence. The chain is the GI side effects.

What this means

The popular framing names a real cluster of problems with the wrong cause.

The peptide isn't doing the damage. The cascade is.
