Occlusal splint or Nightguard

Nightguards / Occlusal Splint


A nightguard, which can be also known as an occlusal splint, is a device worn at night to protect teeth from grinding.


An occlusal splint can also assist with pain and discomfort related to the jaw muscles and jaw joint. The use of an occlusal splint can be the first line therapy for tempero-mandibular joint pain (TMJ). They can be constructed to be worn either in the top jaw or bottom jaw.


An occlusal splint is recommended for people who grind their teeth at night. For it to be effective, it must be worn every night. They usually last around 2 years. If you are a heavy grinder you may need to replace the occlusal splint every year.


If you grind your teeth at night and you don’t wear an occlusal splint, you risk wearing away your teeth, fracturing or breaking teeth, fillings, crown and implants.
