Preformed Mouthguard: As the name implies, the shape of this type of mouthguard has been pre-made. Users only need to choose the right size to wear it. Basically, no adjustment is needed. If you feel uncomfortable after wearing it, there is no other way except to use a knife to make fine adjustments. Preformed mouthguards have gradually faded out of people's sight because they are not very fit and are relatively bulky. They may hinder breathing and speaking. They are now rarely seen on the market.
Thermoplastic Mouthguard: The material used in this type of mouthguard (thermoplastic EVA material) is elastic under normal conditions, and becomes pliable and bendable once heated. Put the mouthguard in hot water until it softens, then bite it to fit the wearer's mouth shape so that it fits tightly against the teeth and gums. After repeating this process several times, the mouthguard will be completely fixed. This type of mouthguard is the most popular mouthguard on the market and is suitable for ordinary sports enthusiasts and semi-professional athletes.
Customized Mouthguard: It requires a regular dentist to make a model of the teeth, or to scan the mouth and then design and make it according to the actual shape of the individual's teeth and dental arches. It fits your mouth better than preformed braces and thermoformed braces, and is more comfortable. Relatively speaking, it also provides more comprehensive protection for teeth, gums and other periodontal tissues.
