Ozempic teeth describes a cluster of dental and oral health changes — dry mouth, enamel erosion, accelerated cavities, gum inflammation — reported by an increasing number of dentists seeing GLP-1 patients. The medication does not chemically damage teeth directly. Four indirect mechanisms do: GLP-1 receptor activation suppressing salivary gland function, dehydration from suppressed thirst compounding dry mouth, stomach acid from reflux and vomiting eroding enamel, and nutritional deficiencies from reduced food intake depleting the minerals teeth need. Unlike most GLP-1 side effects, dental damage from enamel erosion is not reversible when the medication stops. This article covers all four mechanisms, the seven-point oral protection protocol, and the one thing most people do wrong after vomiting that actively accelerates enamel damage.
