Rugby Mouthguards: Boil-and-Bite vs Custom-Fitted

How boil-and-bite and custom-fitted rugby mouthguards compare on fit, breathing and protection, how to fit one, and when to replace it.

Quick answer

A mouthguard protects teeth, lips and jaw in contact. Boil-and-bite guards are inexpensive and molded at home; custom-fitted guards are made from a dental impression and fit more closely, which most players find easier to breathe and talk through. Many unions and competitions require mouthguards, especially in age-grade rugby. Replace a guard when it no longer fits snugly, when it is damaged, or as teeth change in growing players.

The right mouthguard is the one a player actually keeps in. Fit decides that.

Fitting a boil-and-bite guard

  1. Read the instructions; times vary between brands.
  2. Soften in hot water.
  3. Cool for a few seconds so it is not too hot.
  4. Place, bite gently and suck to pull the material onto the teeth.
  5. Cool in cold water and check the fit.

Care

Rinse after use, store in a vented case, and keep away from heat, which can warp it. Replace when worn, torn or loose.

Braces

Players with braces need a guard made for orthodontic use. Ask the orthodontist.

Other protection

Approved headguards and padding are covered in Regulation 12 explained. For contact training, see tackle bags and shields.

Common questions

Are mouthguards required in rugby?

Many unions and competitions require them, especially for youth players. Check your union's rules.

Do mouthguards prevent concussion?

There is no clear evidence that mouthguards prevent concussion. Their proven benefit is protecting teeth and mouth.

How do I fit a boil-and-bite mouthguard?

Follow the maker's instructions: soften in hot water, cool briefly, then bite and suck to mold it. Many can be refitted if the first attempt is poor.

How often should young players replace mouthguards?

Often, as teeth and jaws grow. Check the fit each season.
