How Custom Mouth Guards Work

Custom mouth guards are designed to fit your mouth perfectly. They are made from a mold of your teeth, which ensures comfort and protection.

When you grind your teeth, the mouth guard acts as a barrier. It helps absorb the pressure and reduces the impact on your teeth and jaw. This can prevent damage and lessen discomfort.

To create a custom mouth guard, a dentist takes impressions of your teeth. Then, the mouth guard is made from durable materials that can withstand grinding.

  • Fits securely in your mouth
  • Helps prevent tooth wear
  • Reduces jaw pain

  • Thickness: Consider a guard that balances protection and comfort. Too thick may feel bulky.
  • Breathability: Some designs allow for easier breathing, which can help you feel more comfortable.
  • Easy to Clean: A mouth guard that is easy to clean will help maintain good oral hygiene.
