The short answer is individuals who clench or grind their teeth in their sleep. In fact, around 10% of the population grinds their teeth while sleeping, resulting in temporomandibular pain, facial muscle discomfort, and headaches. For many people, night guard devices provide integral protection by preventing the painful symptoms that often accompany teeth clenching, grinding, or bruxism. Moreover, night guards lessen the wearing down of the teeth by inhibiting such grinding.
Furthermore, post-orthodontic patients or even individuals in general find night guards useful in preventing teeth from shifting over time as well as inhibiting the ability to clench and grind the teeth while sleeping. By keeping the teeth in place and alleviating facial muscular and joint pain, night guards force users to bite evenly. Facilitating an aligned bite helps to evenly distribute concentrated muscle stress and tension that people often endure. In addition, keeping the teeth in place disperses the pressure from chewing and biting instead of allowing a few teeth to absorb the impact. In inflamed gum tissue, individual tooth or teeth taking more pressure than normal (trauma from occlusion) can accelerate bone loss. Night guards help prevent such bone loss by lessening trauma from occlusion.
One type of implant-supported denture that I place is called an “overdenture.” This type of dental implant forms a gum-supported base onto which a removable denture can be placed; overdenture implants are typically performed on the bottom teeth. But what are the fundamental differences between a standard denture and an overdenture, and why would someone choose an implant overdenture as opposed to a full or partial traditional denture?
