Custom-made are individually created for you by a dentist. They provide excellent fit, comfort and protection for your teeth.
Boil and Bite.
Boil and bite mouthguards come from sporting goods stores. They’re boiled in water to soften the plastic. They are then inserted around the teeth while still hot, conforming to the shape of your mouth.
Stock mouthguards are pre-formed. They usually come in small, medium and large sizes that don’t fit particularly well and may create issues when speaking.
