If you grind or clench your teeth at night, you may have heard about a device called a “night watch.” More commonly known as a night guard, occlusal guard, or bite splint, this appliance can be a lifesaver for protecting your teeth from the damaging effects of bruxism (teeth grinding). It also helps alleviate jaw pain, headaches, and other symptoms of temporomandibular joint (TMJ) disorders.
Once you realize you need one, the next question is inevitable: will my dental insurance help pay for it? The answer, like so many things in the world of insurance, is “it depends.” This guide will explore the complex relationship between dental insurance and night guards. We will clarify what “night watch” means in a dental context, explain how insurance companies classify these devices, and give you the tools to navigate your own coverage.
Does Dental Insurance Cover Night Watch Costs?
Clarifying the Term “Night Watch”
First, let’s be clear. The term “night watch” is not a standard dental or insurance term. When people use this phrase, they are almost always referring to one of the following:
-
A Night Guard for Bruxism: A custom-fitted, removable appliance worn over the teeth (usually the upper teeth) to prevent them from grinding together during sleep. This is the most common meaning.
-
A CPAP Machine for Sleep Apnea: Continuous Positive Airway Pressure (CPAP) is a medical treatment for obstructive sleep apnea. The machine delivers a constant stream of air through a mask to keep your airway open. This is a medical device, not a dental one.
-
A Mandibular Advancement Device (MAD): This is a dental appliance that fits over the upper and lower teeth and moves the lower jaw forward. It is used to treat snoring and mild to moderate sleep apnea.
The distinction is critical because insurance coverage for each is very different. For the purpose of this guide, we will focus primarily on the dental night guard for grinding, while also clarifying coverage for the other devices.
Night Guard for Grinding: A Dental Insurance Issue
A night guard for bruxism is considered a dental treatment. Therefore, whether it is covered depends on your specific dental insurance plan.
How Dental Insurance Classifies Night Guards
Most dental insurance plans categorize services into three classes: Preventive, Basic, and Major.
-
Preventive: Cleanings, exams, X-rays (often covered at 100%).
-
Basic: Fillings, simple extractions (often covered at 70-80%).
-
Major: Crowns, bridges, dentures (often covered at 50%).
An occlusal guard or night guard for bruxism is usually classified as a Major service. This means a few things for your coverage:
-
You will likely pay a co-insurance of 50% or more.
-
Your plan’s deductible will apply.
-
The cost of the guard will count against your annual maximum.
The Typical Cost of a Custom Night Guard
Before we discuss coverage, it helps to know the cost of the device itself. A custom-made night guard from your dentist is far superior to a boil-and-bite one from the drugstore. It fits precisely, is more comfortable, and is more effective at protecting your teeth.
-
Dentist-Made Hard Acrylic Night Guard: $400 – $800
-
Dentist-Made Soft or Dual-Laminate Guard: $300 – $600
If your insurance covers this as a Major service at 50%, you would still be responsible for $150 to $400. You may also have to pay the full cost if you have not met your deductible.
Important Note: Many dental insurance plans have “missing tooth clauses” or “replacement clauses,” but they also often have specific frequency limitations for night guards. For example, a plan might only pay for a new night guard once every three or five years. You cannot simply get a new one every year and expect it to be covered.
When Medical Insurance Might Be Involved
In some rare and specific cases, a night guard might be billed to your medical insurance, not your dental insurance. This happens when the bruxism is a symptom of a broader medical condition, or when the treatment is for something other than just protecting the teeth.
-
TMJ Disorder Treatment: If you have been diagnosed with a temporomandibular joint (TMJ) disorder, and the night guard is part of a comprehensive treatment plan for that medical condition, your medical insurance might provide some coverage. This is complex and often requires a lot of documentation from your dentist or doctor.
-
Post-Surgical or Trauma: If the guard is needed as part of recovery from a jaw injury or surgery, medical insurance might be involved.
This is not the norm. Most of the time, a night guard is a dental expense.
Coverage for Sleep Apnea Devices
If you were referring to a device for sleep apnea, the coverage picture is completely different.
1. CPAP Machine (Medical Insurance)
A CPAP machine is a medical device used to treat a medical condition: obstructive sleep apnea. Therefore, it is covered by medical insurance (Medicare Part B or private health insurance) , not dental insurance.
Coverage for CPAP typically falls under “Durable Medical Equipment” (DME). You will need a sleep study to get a diagnosis, and the machine and supplies must be prescribed by a doctor. With medical insurance, you will likely pay a portion of the cost, subject to your deductible and co-insurance. The machine itself can cost $500 to $3,000.
2. Mandibular Advancement Device (MAD)
This is a gray area. A MAD is a dental appliance, made by a dentist. But it is used to treat a medical condition (sleep apnea). This can lead to a billing tug-of-war between your medical and dental insurance.
-
Dental Insurance: May cover the MAD as a Major service, similar to a night guard.
-
Medical Insurance: May cover it if you have documented sleep apnea, have not tolerated CPAP, and the MAD is deemed medically necessary.
In many cases, patients are able to get coverage from one or the other, but it requires persistence and good communication between your dentist’s office and your medical doctor.
How to Get Your Night Guard Covered
If you need a night guard for grinding, don’t just assume it won’t be covered. Take these steps to maximize your benefits.
1. Get a Proper Diagnosis
The first step is a dental exam. Your dentist needs to document the signs of bruxism. This includes worn-down tooth enamel, chipped teeth, a scalloped tongue, and reports of jaw pain or headaches. A simple request for a “night guard” without a documented need is likely to be denied.
2. Ask for a Pre-Authorization
This is the most important step. Your dental office should submit a pre-authorization (also called a pre-determination) to your insurance company. They will send X-rays, photos, and a narrative explaining why the guard is medically necessary. The insurance company will then send you a written answer stating exactly how much they will pay.
3. Understand Your Plan’s Limitations
Call your insurance company directly. Ask these specific questions:
-
“Is an occlusal guard (night guard) a covered benefit on my plan?”
-
“Is it classified as a Basic or Major service?”
-
“What is the co-insurance I will have to pay?”
-
“How often will you pay for a new night guard?”
-
“Do I have a deductible I need to meet first?”
4. Consider a Dental Discount Plan
If your insurance does not cover night guards at all, or if you don’t have insurance, a dental discount plan can help. These plans charge an annual fee and provide a list of dentists who have agreed to charge lower rates. You can often save 20-40% on a night guard this way.
The Cost of Not Getting a Night Guard
When weighing the cost of a night guard, it is essential to consider the cost of not getting one. Teeth grinding is destructive. Over time, it can lead to:
-
Severe Tooth Wear: Your teeth will become flattened, short, and sensitive.
-
Cracked and Fractured Teeth: The pressure from grinding can crack healthy teeth. A cracked tooth that cannot be saved requires extraction.
-
Crowns and Root Canals: Damaged teeth need expensive repairs. A single crown costs $1,000 or more.
-
TMJ Problems: Chronic jaw pain, clicking, and locking can develop.
-
Headaches and Migraines: The muscle tension from grinding can cause chronic pain.
A $500 night guard is a bargain compared to the thousands of dollars you could spend repairing the damage caused by years of untreated grinding. It is a classic example of an ounce of prevention being worth a pound of cure.
| Expense | Typical Cost | Long-Term Cost of Skipping It |
|---|---|---|
| Custom Night Guard | $400 – $800 | Protects against all costs below |
| Dental Crown (1 tooth) | $1,000 – $2,500 | Required for cracked/worn teeth |
| Root Canal + Crown | $2,000 – $4,000 | Required if grinding exposes nerve |
| Tooth Extraction + Implant | $3,000 – $5,000 | Required for unrestorable tooth |
| TMJ Treatment | Varies widely | Can be thousands of dollars |
Conclusion
Dental insurance often covers a portion of the cost of a night guard for teeth grinding, but it is usually classified as a Major service. This means you will likely pay a significant co-insurance. The key is to get a proper diagnosis, request a pre-authorization, and understand your plan’s specific rules. If your “night watch” refers to a CPAP machine for sleep apnea, that is a medical device covered by medical insurance, not dental. Regardless of coverage, investing in a night guard is a wise financial decision that can prevent thousands of dollars in future dental repairs.
Frequently Asked Questions (FAQ)
1. Why did my insurance deny my night guard claim?
The most common reasons for denial are: 1) the insurance company determined the guard was not “medically necessary” based on the documentation provided, 2) your plan has a frequency limitation and you got a guard too soon after the last one, or 3) you have not met your deductible for the year. Ask your dental office to submit more documentation or appeal the decision.
2. Are over-the-counter night guards a good alternative?
Over-the-counter (OTC) guards are much cheaper ($20-$50), but they are not custom-fit. They are often bulky, uncomfortable, and can even cause jaw pain because they don’t position your bite correctly. They can be a short-term solution for occasional grinding, but a custom guard from your dentist is the gold standard for protection and comfort.
3. What is the difference between a night guard and a sports guard?
A sports guard is designed to protect your teeth from sudden, traumatic impact during athletics. A night guard is designed to protect your teeth from the sustained, heavy forces of clenching and grinding. They are made from different materials and for different purposes. Do not use one in place of the other.
4. Will a night guard stop me from grinding?
No, a night guard does not stop the grinding habit. It simply provides a protective barrier between your upper and lower teeth, absorbing the force and preventing wear and damage. The grinding behavior itself will likely continue.
5. My dentist says I need a night guard for my jaw pain. Will my medical insurance cover it?
It is possible, but not common. If your dentist can document that the guard is part of a treatment plan for a diagnosed TMJ disorder, your medical insurance might consider it. However, medical insurers often have exclusions for TMJ treatment. Your dental insurance is the first place to try.
