How to Mold a Mouthguard for Your Child

A well-fitted mouthguard is essential for protecting your child’s teeth, gums, and jaw during sports. If you're wondering how to mold a mouthguard at home, the good news is that it only takes a few simple steps with the right guidance.

Why Fit Is So Important

Mouthguards that are too loose or bulky can slip, cause discomfort, or offer less protection. A secure fit helps the mouthguard stay in place during movement, lets your child breathe and speak comfortably, and improves overall safety.

How to Mold a Mouthguard at Home

If your child’s mouthguard is a boil & bite model, here’s a general guide:

  • Boil water and remove it from the heat.
  • Submerge the mouthguard for the recommended time, usually 30 to 60 seconds.
  • Remove carefully and let it cool slightly.
  • Place it in your child’s mouth and press it around their teeth using fingers and tongue.
  • Have them bite down gently to shape the fit.
  • Cool in cold water to set the shape.
  • Test the fit: the mouthguard should stay in place without biting down. Remold if it feels loose or uncomfortable.

Always follow the instructions that come with your specific model. Boiling time and technique can vary slightly.
