Levodopa/Carbidopa (Sinemet) and dental care
Parkinson's patients on levodopa face a layered dental picture: the medication itself can cause dry mouth and altered taste, while the disease causes tremor, swallowing difficulty, and reduced dexterity that affect both oral hygiene and dental procedures. Drooling is also common (paradoxically, despite reduced saliva, because of impaired swallowing). Each piece needs its own approach.
Never start, stop, or change a medication based on what you read here. Bring questions to your dentist, physician, pharmacist, or prescribing clinician.
