While they do take some getting used to, dentures are a great solution to tooth loss. Many people believe that once you receive dentures, you're set for life. However, Dr. Alin Alkass notes that this isn't actually the case. Dentures stain and wear down and, because the bone and muscle structure in your face is always changing, they need frequent adjustments to ensure that they fit properly and work as efficiently as possible.If you have dentures, you should visit your dentist at least once a year for a refitting, and you should replace your dentures every five to seven years. Are your dentures loose? Do they shift when you eat? Are you using an excessive amount of denture paste? There is a way to secure your dentures using dental implants. Usually two to four implants are surgically placed in the jaw and special adapters connect the dentures to the implants!
