Teeth Gridning/Night Guards Vancouver
Often patients who grind their teeth at night are unaware of their habit, but the forces exerted on both the teeth and the Tempromandibular Joint (TMJ) can be quite destructive. A custom‐made night guard can protect the teeth and relieve pressure on the TMJ.
Bruxism is an oral parafunctional activity which commonly occurs with most people at some point in their lives. The two main characteristics of this condition are grinding the teeth and clenching of the jaw. These actions usually occur during a person’s sleeping hours, but occasionally they occur during the day.
Bruxism is one of the most common known sleep disorders. Chewing is a neuromuscular activity controlled by a subconscious process, but more highly controlled by the brain. During sleep, the subconscious process may become active while the higher control is inactive (asleep), resulting in bruxism. The most common symptoms are earaches and headaches, depression, eating disorders, anxiety, and tooth wear.
There is no definitive treatment for bruxism, mouth/night-guards can protect teeth and restorations under involuntary jaw movements.

Since retention is poor, the athlete holds the mouthguard in place by clenching his or her teeth together.
