Start with fit and use
Stock, moldable, and custom-made guards offer different fits and levels of individual adjustment. A guard should stay comfortably in place and allow you to breathe and communicate. If it is so bulky or loose that you routinely remove it, discuss another option. Bring the sport, position, and any league requirements into the conversation so the advice suits the activity you actually do.
Allow for a changing mouth
Children's growing mouths, new teeth, orthodontic treatment, and dental restorations can affect fit. A person with braces should ask the dentist or orthodontist which type of guard is appropriate. Do not assume last season's guard still fits because it looks intact. Bring it to dental visits and point out rubbing, chewing damage, or a place where it no longer seats properly.
Make care part of the routine
Clean the guard according to its instructions and store it in a protective ventilated case. Keep it away from heat and check for tears, distortion, and wear before use. Replace or reassess a damaged or poorly fitting guard. After a blow to the mouth, a guard's presence does not rule out injury; report pain, a changed bite, loose teeth, or damaged dental work for assessment.
GOOD QUESTIONS
A little more clarity.
Can I use my sports guard for nighttime grinding?
These appliances serve different purposes. Ask for an assessment before using one interchangeably with the other, particularly if you have jaw symptoms or a changing bite.
