What should i use to stop grinding my teeth at night besides a splint?

There are many: Oral devices that are helpful in this regard. Two of the most common ones are the nti and the bitesoft devices - both of which cause posterior disclusion - prevent your back teeth from touching so there is a space between your back teeth. Consult with your dentist to see which device would be best suited for your condition. Hope this helps.

Many causes: Someone may grind their teeth for a number of reasons. Often, the problem occurs because the muscles of the face and jaw are trying to get the teeth in a comfortable position. The muscles may be in spasm, you may have a tmj/tmd problem, stress, infection. Best to see a dentist asap. Often the cause is difficult to determine, so may have to treat the symptoms with a mouthpiece.
