Night guard insurance guide
Updated September 1, 2026.
Dental insurance may cover some of the cost of a custom night guard, but there is no universal coverage rule. Benefits depend on your individual plan, why the appliance is being provided, plan limitations and how the night guard is obtained.
Does dental insurance cover night guards? Sometimes. Some dental plans include occlusal guards as a covered benefit, while others exclude them or apply deductibles, frequency limits, documentation requirements, network rules or other conditions. Check your specific plan before assuming that a night guard will be reimbursed.
Does dental insurance cover custom night guards?
Some dental plans provide benefits for custom occlusal guards, particularly when the appliance is being provided for a documented dental condition such as bruxism. Other plans may provide no benefit at all.
Humana, for example, tells members that not all dental insurance plans pay for night guards and recommends checking with the individual plan to determine whether some or all of the cost may be covered.
UnitedHealthcare's 2026 dental clinical policy likewise lists the current occlusal-guard procedure codes, but specifically notes that the member's own benefit-plan document governs coverage.
The important distinction: a dental service can have a recognized procedure code without being a covered benefit under your particular insurance policy.
What affects whether a night guard is covered?
Insurance plans can differ substantially. When a plan does provide benefits for an occlusal guard, your final reimbursement or out-of-pocket cost may depend on several factors.
The plan must actually include an occlusal guard within its covered dental benefits.
A covered service does not necessarily mean the insurer pays the entire cost.
Some plans limit how often benefits are available for a new or replacement appliance.
Coverage may depend on who provides or bills for the appliance and whether that provider participates in the plan.
Some claims may require clinical documentation, a narrative, radiographs or other supporting information.
Deductibles, annual maximums and other benefit limitations may affect what the plan ultimately pays.
How much will insurance pay for a night guard?
There is no reliable percentage that applies to everyone.
Even if your policy lists an occlusal guard as a covered benefit, the insurer may apply its own allowed amount, deductible, coinsurance, network rules and annual maximum.
For that reason, the useful number is not simply the percentage shown in a benefits summary. It is the estimated amount your particular plan will pay and the amount you will actually owe.
If you plan to receive a night guard through your dentist, ask whether the dental office can submit a pre-treatment estimate or predetermination to your insurer before the appliance is made.
What should I ask my dental insurance company before buying a night guard?
Call the member-services number on your dental insurance card and ask specific questions rather than simply asking, “Do you cover night guards?”
If possible, tell the representative that you're asking about an appliance for bruxism or teeth grinding.
The current fabrication codes distinguish hard full-arch, soft full-arch and hard partial-arch occlusal guards.
This is especially important if you're considering purchasing a custom guard directly from a laboratory or online provider.
Ask whether your plan accepts member-submitted reimbursement claims and whether there are provider requirements.
Ask about an itemized invoice, treatment narrative, prescription, radiographs, clinical records or other supporting documentation.
Obtaining an estimate in advance can reduce surprises when reimbursement is important to your purchase decision.
Ask about any frequency limitation before replacing a guard that was previously paid for by the plan.
Ask how the deductible, coinsurance, allowed amount and annual benefit maximum apply.
Dental coding
What is the dental insurance code for a night guard?
Current CDT codes distinguish occlusal guards by construction and arch coverage:
Those codes describe dental procedures; they do not guarantee payment by an insurance plan.

Sentinel + dental insurance
Does Sentinel Mouthguards accept dental insurance?
Sentinel Mouthguards does not bill dental insurance directly.
Sentinel provides custom dental guards directly to customers rather than billing through your dental office. Because every dental plan has its own rules, Sentinel cannot determine whether your insurer will reimburse your purchase.
If you are considering a Sentinel guard and dental-insurance reimbursement is important to you, contact the insurer before ordering.
Specifically ask whether your plan accepts member-submitted claims for a custom occlusal guard purchased directly from an outside laboratory or online provider and what provider information or clinical documentation would be required.
If your insurer tells you that the appliance must be prescribed, delivered or billed through a dental provider in order to receive benefits, obtaining the guard through your dental office may be the appropriate route for using that coverage.
Can I submit a Sentinel receipt to dental insurance?
You can ask your insurer whether your particular plan allows you to submit a claim yourself.
An itemized receipt alone does not guarantee reimbursement. Depending on the plan, the insurer may also require provider information, clinical documentation or other records that Sentinel may not be able to supply as a treating dental office would.
Before purchasing specifically because you expect reimbursement, ask your insurer whether:
- A direct-to-consumer custom occlusal guard is eligible under your benefits
- You are allowed to file the claim yourself
- The claim requires a licensed dental provider's information
- A diagnosis, prescription, narrative or clinical records are required
- Radiographs or other documentation are required
- A replacement-frequency limitation applies
If the insurer cannot confirm that the purchase would qualify, do not assume that submitting a receipt later will result in reimbursement.
Dentist-provided guard vs. direct-to-consumer custom guard
Insurance can change the economics of the decision, so compare your actual expected out-of-pocket cost rather than the retail prices alone.
| Option | Insurance considerations | Service model |
|---|---|---|
| Custom guard through a dentist | May qualify for plan benefits depending on the policy, provider network and clinical requirements. | May include an in-person examination, impression or scan, clinical fitting and follow-up through the dental office. |
| Sentinel custom guard | Sentinel does not bill dental insurance. Any member reimbursement depends entirely on the individual plan. | Custom fabrication from a home dental impression or compatible digital scan, with Sentinel fit support and applicable product guarantees. |
Neither route is automatically right for everyone. If you have unexplained dental pain, significant tooth damage, extensive restorative work, bite concerns or are unsure whether a night guard is appropriate, consult a dentist before ordering an appliance.
What if my dental insurance does not cover a night guard?
Dental insurance and HSA/FSA eligibility are separate issues.
A purchase that is not reimbursed by your dental plan may still qualify for payment with HSA or FSA funds depending on the expense, your circumstances and applicable plan rules.
Sentinel offers a TrueMed checkout option for qualified customers. Rather than duplicating that process here, see our dedicated guide:

Dental insurance and night guard FAQs
Does dental insurance cover night guards for teeth grinding?
Some dental plans provide benefits for occlusal guards used for bruxism or teeth grinding, while others do not. Even when covered, benefits may be subject to deductibles, coinsurance, frequency limits, provider rules and documentation requirements.
Does dental insurance pay the full cost of a night guard?
Not necessarily. A covered benefit can still be subject to a deductible, coinsurance, an insurer's allowed amount, network rules and the plan's annual maximum.
Does insurance cover an online custom night guard?
It depends on the plan. Some policies may have provider or billing requirements that affect reimbursement for an appliance purchased outside a dental office. Ask your insurer specifically about direct-to-consumer or member-submitted claims before purchasing.
Does Sentinel Mouthguards bill dental insurance?
No. Sentinel does not bill dental insurance directly. Customers who want to seek reimbursement should first ask their insurer whether their plan permits a member-submitted claim for a Sentinel purchase and what documentation is required.
What dental code is used for a night guard?
Current CDT fabrication codes include D9944 for a hard full-arch occlusal guard, D9945 for a soft full-arch guard and D9946 for a hard partial-arch guard. Having the correct code does not guarantee coverage.
Do I need prior authorization for a night guard?
Requirements vary by plan. Ask your insurer whether preauthorization, a pre-treatment estimate, clinical review or supporting documentation is required before the appliance is made.
Can I use HSA or FSA funds if dental insurance does not cover my guard?
Possibly. HSA/FSA eligibility is separate from dental insurance coverage. Sentinel offers TrueMed for qualified customers; eligibility and reimbursement remain subject to the applicable requirements and plan administrator.
