A sports mouthguard needs another look when it is damaged, worn, or no longer fits comfortably. For children and teens, a guard that worked earlier may need replacement as the mouth grows and teeth change. Check it before the next practice rather than discovering a problem at the sideline.
Make fit part of sports preparation
A mouthguard helps cushion impacts and protect teeth and nearby soft tissues. The American Academy of Pediatric Dentistry's sports-injury policy supports properly fitted mouthguards for organized sports with a risk of injury to the mouth and face. Protection should be discussed as part of a child's dental visits, alongside the activities they enjoy.
Tell the dental team about practices as well as competitions, and mention recreational activities too. A team equipment list is a useful starting point, but it is worth asking about your child's particular sport and mouth.
Look at the guard and listen to your child
Before packing the sports bag, take out the guard and check for visible wear or damage. Ask your child whether the fit feels different and whether using it has become uncomfortable. Do not assume a complaint is simply reluctance to wear equipment.
The ADA's MouthHealthy mouthguard guide advises replacing guards that are worn, damaged, or ill-fitting. Children and teens may need replacements more often because their mouths are changing. Bring the current guard to a dental checkup so its condition and fit can be assessed.
A practical pre-season note can include the date the guard was obtained, changes in teeth or orthodontic treatment, and any complaints during use. This keeps the conversation specific without asking a parent to judge the exact fit alone.
Choose a type with help when needed
The ADA's review of athletic mouthguards describes custom-made, mouth-formed “boil-and-bite,” and ready-made stock options. A dentist can help compare the options for fit and use. Stock guards have a generic shape and may be less secure; custom guards are individually fitted.
If using a mouth-formed guard, follow that product's instructions rather than copying a heating time from another package or an online video. The ADA notes that improper preparation can affect fit and retention. Ask for help if the result is uncomfortable or seems unstable.
Keep it clean, dry, and away from heat
MouthHealthy recommends rinsing the guard before and after use, cleaning it regularly in cool, soapy water, and rinsing thoroughly. Store it in a sturdy ventilated container and keep it away from sun and hot water. Check for wear between games.
Give the case a consistent place in the sports bag. After use, make cleaning and storage part of putting equipment away, so the next practice does not begin with a search for the guard. Keep it out of pets' reach too.
FAQ: What if my child has braces?
Ask the dentist or orthodontist to select an appropriate mouthguard. MouthHealthy explains that a guard can help protect braces and the lips and cheeks around them. Do not assume the guard used before braces will still be suitable. Mention any recent orthodontic changes when asking for a fit check.
