As the alveolar bone undergoes resorption and the facial structures collapse due to the loss of vertical dimension, wear and tear of the old dentures, and other intraoral changes which arise due to prolonged denture use without proper aftercare, some people will experience something called a sunken lip. This is evident when your lip is starting to fall in, resulting in creation of new facial wrinkles under your nose and lower lip. This can be prevented with proper denture build up on the denture base flanges, giving you the facial support you need, while providing you with a more youthful appearance. Please inquire about such options.
