Mouth Guard

Mouthguards are made of plastic meaterial and used by many to protect their teeth from injury or excessive wear.

Who would need to use a mouthguard?

  • Anyone who participates in contact sports should wear mouthguards. Mouthguards should be used when there is a risk of injury either from colliding with another athlete, or when there is risk of accidental injury from sporting equipment. Adult and chlidren who participate in games such as football, boxing, hockey and cricket, to mention a few, would benefit from the use of mouthguards.
  • Mouthguards could also be recommended by a dentist when one experiences night-time tooth grinding (bruxism). This would usually be custom-made for the individual to prevent excessive tooth wear.

There are three types of mouthguards available.

  1. Prefabricated mouthguards

    These can be obtained from pharmacies or sporting goods stores. It is very affordable and can be used right away by the wearer.

    The drawback of the prefabricated mouthguard is that, as it may not fit the wearer well, it can be uncomfortable. A point of note is that when the mouthguard does not fit well, it does not protect the teeth.

  2. Thermoplastic mouthguards

    These can also be obtained from pharmacies or sporting goods store. It provides a slightly better fit when compared to the prefabricated mouthguard. This is because the material can be warmed up in moderately hot water and then shaped to fit the wearers’ jaw.

  3. Custom made mouthguards

    Custom made mouthguards are made specifically for the wearer. A dentist would first make a mould of the jaw. This would be sent to a dental labarotory where a mouthguard is constructed upon the mould. Hence, this type of mouthguard provides the best fit and protection
