Can be useful for
A product can support daily care but can’t treat a dental problem on its own. See a dentist if symptoms persist.
Choosing night guards and mouthguards
- Ask your dentist about a custom-made mouthguard – especially for regular contact sport.
- If you use a self-fit guard as a stop-gap, follow the fitting instructions carefully and check it stays in place.
- Children may need a new guard more often as their jaws grow.
- Clean the guard after each use, dry it and store it in a hard plastic case, away from heat.
- For grinding, see a dentist rather than relying on an over-the-counter guard.
