There are a few different types of mouth guards that can be used to help with teeth grinding, and it really depends on the individual’s needs as to which one would be best. If you have mild to moderate teeth grinding, a boil-and-bite mouth guard may be all you need. These are made from a thermoplastic material that you soften in boiling water, then bite into so it molds to your teeth. They’re relatively inexpensive and can be found at most drugstores.
If you have more severe teeth grinding or clenching, you may need a custom-fitted mouth guard. This type is made from a hard acrylic material and is fit specifically to your bite by a dentist or other dental professional. Because they’re individually made, they tend to be more expensive than boil-and-bite guards. But they’re also much more comfortable and effective at preventing damage to the teeth.
No matter which type of mouth guard you use, it’s important to clean it regularly with soap and water (or toothpaste for custom-fitted guards) and store it in a cool, dry place when not in use.
