Night guards and insurance
Why night guards are often limited or excluded, what plans that do pay usually want, and how to quote one.
Coverage for a night guard (an occlusal guard) varies more than most services. Many plans list it under limitations or exclusions; others pay it only for a specific diagnosis such as grinding.
What decides the payment
- Exclusions. Check whether guards are covered at all.
- The reason. Plans that pay usually want the diagnosis and a narrative saying what the guard treats.
- Frequency. Plans that pay often limit replacements to one in a set number of years.
- Medical plans. A device for sleep apnea is a different appliance and is often a medical claim, not a dental one.
Before the visit
- Check exclusions and limitations for guards.
- If it's covered, note the diagnosis and the reason in the chart for the claim.
- If it isn't, quote the full fee up front.
This is how plans usually work, not how every plan works. The patient's own plan documents and the insurer decide what's paid.
