Welcome back to Dentist Camberwell’s  blog. Today you will find out what the difference between custom fitted mouthguards and counter fitted mouthguards are. Also, how to care for your mouthguard.


Over the counter mouthguards or “bite and boil” are far less effective than those that are custom fit by your dentist.

Bite and boil mouthguards only require you to place the mouthguard in boiling water then self fit by biting into the mould.

This results in ill-fitting mouthguards consequently ending in dental trauma and injuries that could have been prevented, if only it was fit to your mouth’s individual needs.

Poor fitting mouth guards require the user to constantly be holding the mould in position, resulting in distractions from the sport that may end in injury.

On the other hand, custom fitted mouthguards are made by your dentist and designed so that it is fits YOUR mouth.

The dentist will take impressions of your teeth to create a plaster model. This allows the dentist to properly assess your mouth and teeth, therefore providing a mouthguard made to solely suit your individual needs.

Custom fit mouthguards will not shift or fall out, therefore it is comfortable, well fitted and allows you to speak clearly, without restricting your airways.

The best mouthguards are those made by your dentist and although they are more expensive than its store bought counter part, it is more comfortable and protects you better. The cost of a custom fitted mouthguard is far cheaper than the expense of complex and lengthy dental treatment that is a product of an ill fitting mouthguard or no mouthguard at all.


Always store in a rigid container (supplied by your dentist on completion of your mouthguard).

Always rinse your mouthguard after use.

Mouthguards may change shape in hot temperatures so always ensure that it is stored in a cool place.

On occasions rinse your mouthguard with mouthwash.

Ensure that your mouthguard is checked regularly by your dentist to make sure that it is fitting correctly.

You may need a replacement mouthguard after your secondary teeth have come through or if you have damaged the mouthguard
