Injectable treatments typically evoke images of wrinkle-free Hollywood celebrities, but advances in dental research have shown that these treatments can be just as effective at treating dental pain, tension headaches, and migraines due to teeth clenching. They work by relaxing the muscle responsible for the clenching habit. Injectables are non-toxic and a reversible treatment. The dentist always performs a thorough evaluation of the facial features to determine what treatment is best for your needs.
