An imbalanced bite may increase or speed up bone destruction. Adjusting the bite (carefully grinding a thin layer of the teeth that are hitting too hard) allows the teeth to meet properly and distributes stress to stronger teeth.
A biteguard (also called a nightguard) is a removable appliance that is typically worn at night to protect the teeth and to relax the jaw muscles. These are usually needed by people who clench or grind their teeth (bruxism), which is a common habit associated with stress or TMJ problems.
Splinting is occasionally needed to attach loose teeth together, making you feel more comfortable.
