A night guard (occlusal guard) is a custom appliance a dentist makes to protect teeth from bruxism — grinding and clenching during sleep. Because it treats a diagnosed condition, many dental plans cover it, paying a percentage of the allowed cost after any deductible or waiting period, up to the annual maximum.
Coverage isn't universal. Some plans exclude occlusal guards entirely or classify them in a way that pays little, and most cap how often they'll cover a replacement (commonly once every three to five years). A guard tied to TMJ (jaw joint) treatment may fall under separate TMJ provisions or be excluded altogether.
Over-the-counter guards aren't billed to insurance. Whether your custom night guard is covered, at what percentage, and how often it can be replaced is set out in your plan's schedule of benefits.
What people typically pay
When a plan covers the guard, you usually pay your deductible plus the remaining share after the plan pays its percentage up to your annual maximum. The exact patient responsibility varies widely by plan, the allowed fee, and how much of your annual maximum is left — a pre-treatment estimate is the reliable way to see your share.
Paying entirely out of pocket, the cost of a custom dental night guard varies widely by region, dentist fees, and the type of guard. Over-the-counter guards cost far less but aren't billed to insurance.
Ranges vary widely by plan, region, dentist fees, and the type of guard — a pre-treatment estimate is the reliable way to see your actual share.
How to actually get it covered
Have your dentist diagnose bruxism (or the relevant condition) and note the grinding or wear on your chart — coverage hinges on treating a documented condition, not just a request.
Ask the office to submit a pre-treatment estimate to your insurer for the occlusal guard so you see the expected payment and your out-of-pocket share before anything is made.
Confirm the replacement-frequency limit and that you haven't had a guard covered within that window; ask the insurer directly if you're unsure of your last claim date.
Verify whether your plan treats the guard as a standard dental benefit versus a TMJ appliance, since TMJ rules or exclusions can change the answer.
Proceed with the custom guard once the estimate confirms coverage, and keep the itemized claim and diagnosis notes in case you need to appeal.
If it's denied, request the specific reason in writing and file an appeal with the dentist's diagnosis and treatment notes attached.
Common questions
What percentage of a custom night guard does dental insurance usually pay?
When a plan covers occlusal guards, it typically pays a set percentage of the allowed amount after any deductible — the exact share varies by plan and by whether your plan classifies the guard as a basic or major service. That coverage applies up to your annual maximum, so a guard billed near the end of a year when your maximum is used up may leave you paying most of the cost yourself.
How do I find out if my plan covers night guards before I commit?
Look for "occlusal guard" or "night guard" in your plan's schedule of benefits, or call the member number on your card and ask whether it's covered, at what percentage, and how often. Your dentist's office can also submit a pre-treatment estimate to the insurer, which comes back showing the expected payment and your share before the guard is made.
How often will insurance replace a night guard?
Many plans cover a replacement only once every few years (commonly once every three to five years), and some are stricter. If you lose or break your guard sooner, or need a new one because your bite changed, the plan may deny it until the frequency window resets — leaving that replacement as an out-of-pocket cost.
Does it matter whether the guard is for grinding versus TMJ jaw problems?
Yes. A guard prescribed to treat bruxism (grinding and clenching) is usually handled under standard dental benefits, while a guard tied to TMJ treatment may fall under separate TMJ provisions or be excluded entirely. How your dentist codes and diagnoses the appliance can determine whether it's paid, so the reason for the guard matters as much as the guard itself.
Is a store-bought night guard ever reimbursable?
Over-the-counter boil-and-bite guards aren't billed to dental insurance, since coverage applies to custom appliances a dentist fabricates. You generally can't submit an OTC guard for reimbursement, and note that IRS Publication 502 lists nonprescription items generally among expenses that aren't includible — so check current rules before assuming an OTC guard qualifies for FSA or HSA use.
