A mouthguard is a protective device worn over the teeth to prevent injuries during sports or other activities. They are especially important for athletes involved in contact sports like football, boxing, or hockey, where the risk of dental injuries is high. Mouthguards help cushion blows to the face, reducing the chance of broken teeth or jaw injuries. There are different types of mouthguards, including stock mouthguards, which are pre-made and ready to wear, and custom mouthguards, which are tailored to fit an individual's mouth perfectly. Wearing a mouthguard not only protects teeth but also helps prevent concussions by absorbing some of the impact during a hit.
