Sports mouthguards are protective devices worn over the teeth to prevent injuries during physical activities. They are commonly used in contact sports like football, hockey, and boxing to reduce the risk of dental injuries, jaw fractures, and concussions. Mouthguards can be custom-fitted by a dentist or purchased as boil-and-bite options from stores. These devices work by absorbing and distributing the impact of blows to the face, helping to protect the teeth and gums. Wearing a mouthguard is essential for athletes of all ages, as it promotes safety and can prevent costly dental repairs in the event of an accident.
