Many people are not aware that by not making frequent visits to their Denturist Office (every 2-3 years), their overall oral health may be jeopardized making their denture wearing ability and comfort harder to achieve. Changes occur in both the bone structure and soft tissues of your mouth. However, between the 5-8 year mark, the actual denture teeth may be worn down enough to cause damage to your tempo mandibular joint from over closing. This can also lead to cracking of the corners of the lips, aging of the face, or even headaches.
