Can I drink coffee after a resin filling?

You can drink coffee after a resin filling, but you do need to manage staining. The surface of resin has microscopic pores, so deeply colored foods such as coffee, curry, and wine can discolor it over time. 1) Rinse your mouth with water right after drinking, and 2) brush 30 minutes to an hour later, and staining will be reduced. Resin that has already discolored can be improved by polishing the surface or replacing it, so have its condition checked at your regular check-up.
