If your partial fits well and feels comfortable, kissing with dentures is almost the same as kissing with natural teeth. If your partial feels loose, secure it in place with denture paste or adhesive strips.
With a few precautions, denture wearers can kiss, eat and perform most other activities with ease. Keep your dentures fresh and clean by gently brushing them twice a day. Soak dentures in water when they are not being worn. If you plan to kiss, ensure the snug fit of your partial with a dab of denture adhesive paste, and then move your lips around to verify that they are secure.
