Levothyroxine and dental care: dry mouth, gums, dental work
Some medications affect oral health in subtle but accumulating ways: dry mouth that increases caries risk, gum changes, taste shifts, or interactions with anaesthesia and bleeding control during dental procedures. For Levothyroxine (Levothyroxine) at 25mcg, 50mcg, 75mcg, 100mcg, 150mcg, dental care matters more than is usually appreciated.
How Levothyroxine affects oral health
Common oral effects of medications include reduced saliva flow (dry mouth, xerostomia), gum overgrowth or recession, oral thrush in immunosuppressed users, and altered taste. Whether Levothyroxine affects oral health depends on its mechanism. Levothyroxine replaces deficient endogenous thyroxine, which is converted in tissues to the active hormone triiodothyronine (T3) by deiodinase enzymes. Reduced saliva is the most common and most consequential because it allows tooth decay and gum disease to progress faster.
Practical guidance for dental care
According to dental practice, patients on Levothyroxine at 25mcg, 50mcg, 75mcg, 100mcg, 150mcg should mention the medication at every dental visit. For chronic medications, more frequent professional cleaning and fluoride application protect against dry-mouth-related decay. For dental procedures, the dentist may need to coordinate with the prescriber regarding bleeding risk, anaesthesia interactions or temporary medication adjustment depending on Levothyroxine.
