Sleep Bruxism: What a Night Guard Can and Cannot Do

Morning jaw fatigue or grinding sounds reported by a partner can raise questions about sleep bruxism. Buying an appliance is not a substitute for understanding the symptoms.

Describe the pattern

Grinding or clenching can be associated with tooth wear and jaw discomfort. Tell the dentist about daytime clenching as well as sleep symptoms, medications and existing restorations.

What a guard is for

A guard may protect teeth from grinding forces. It does not mean every underlying cause has been cured. Fit, use and follow-up should be checked.

Ask practical questions

  • Why is this appliance appropriate?
  • How should it be cleaned and stored?
  • What should I do if it hurts or changes how my bite feels?

Do not choose by thickness alone

A useful discussion focuses on your mouth and symptoms rather than a product's appearance. Mention crowns or implants and bring the appliance to reviews.

Frequently asked questions

Can a sports mouthguard replace a night guard?

Do not make that substitution without advice. The appliances serve different purposes.

How long should I wear it?

Ask for an individual schedule and review plan rather than following a generic online routine.
