I don’t recommend the boil and bite guard. Because the guard is soft and will not be perfectly fitting, they can cause a person to clench and grind even more. A night guard that is well-fitting and is made out of hard plastic material is the best choice. This type of guard makes the experience of clenching or grinding less pleasurable. These hard-plastic guards can withstand pressure and will not wobble, which could result in causing more clenching and grinding.Â
