Plan B 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 Plan B (Levonorgestrel) at 1.5mg, dental care matters more than is usually appreciated.
How Plan B 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 Levonorgestrel affects oral health depends on its mechanism. Plan B's primary mechanism is delaying or preventing ovulation when taken before the LH surge. 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 Plan B at 1.5mg 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 Levonorgestrel.
Frequently asked questions
Does Plan B cause dry mouth? ▾
Some users on Plan B experience dry mouth at 1.5mg; the prescribing information for Levonorgestrel lists frequency when documented. Dry mouth is manageable with frequent water sipping, sugar-free gum, saliva substitutes and consistent dental hygiene.
Do I need to stop Plan B before dental work? ▾
For most dental procedures and most medications, no — Plan B continues at 1.5mg during routine dental work. For some agents (anticoagulants, immunosuppressants, certain Hormones and Birth Control medications), the dentist coordinates with the prescriber on whether a temporary adjustment is needed.
