A nightguard or "occlusal guard" is shaped by Dr. Maddahi so that it fits most comfortably. It is placed on one jaw – generally the bottom - and it acts as a protective layer between the two sets of teeth. Nightguards look similar to mouthguards, but are much less bulky and act only as protection for grinding.
[Bruxism caused this patient to wear down his front teeth. After Dr. Maddahi restored his teeth to normal size with crowns and veneers, he provided this patient with a nightguard to ensure that the new teeth would not be damaged.]
It is a good idea to use a nightguard to avoid major, permanent damage to one's teeth that is often associated with bruxism.
Beyond the head or jaw pain often caused by bruxism, damage may be caused to the teeth by the constant grinding: cracks, fissures, chipping, weakening, and removal of protective tooth enamel that can lead to increased sensitivity to cold and heat.
