For the athletes in your family, we recommend that everyone wears a sports guard to protect his/her teeth, jaw, lips, cheeks and gums from serious injury.
When purchasing a mouth guard for sports, remember not all sports guards are treated equally. The amount of protection a mouth guard provides is based on the quality of the mouth guard placed in the mouth.
A typical off-the-shelf mouth guard is generally loose and does not offer full protection. There are mouth guards that can be custom-fitted at home through a heat and set method, but these also do not provide full protection. A custom-made mouth guard from a dentist office offers full protection for the entire mouth and can be ultra-thin so as not to be a hindrance or nuisance.
