When do you need a night guard for teeth grinding?

Many patients do not realize they grind or clench until they notice tooth wear, jaw soreness, headaches, or a cracked restoration. In some cases the signs are subtle and show up first during a dental exam rather than in the way the patient feels.

That is why the conversation often starts with visible wear or bite stress rather than a dramatic symptom.

A night guard may be worth discussing when the teeth are taking repeated stress, restorations are breaking down, or morning jaw tension is becoming a pattern. It is not a cure for every problem, but it can be an important protective step for the right patient.

The reason for using one should be clear, not automatic.

A dentist can help tell the difference between ordinary wear and a level of grinding that is more likely to damage teeth or existing dental work. That matters because some patients need monitoring, while others benefit from more active protection.

The more clearly the problem is explained, the easier it is to decide what to do next.
