Does Insurance Cover Custom Mouth Guards for Teeth Grinding?

March 20, 2026 9:00 am

Many people grind their teeth for years without realizing it. The clues often show up gradually. A patient might mention waking up with jaw soreness, or noticing that cold drinks suddenly make certain teeth feel sensitive. During an exam, the dentist may see flattened chewing surfaces or small enamel fractures—subtle signs that the teeth have been under steady pressure.

When grinding or clenching becomes a concern, dentists often recommend a custom nightguard, sometimes called an occlusal guard. These appliances are worn while sleeping and are designed to protect the teeth from the forces created by nighttime grinding.

That recommendation usually leads to a practical question: does dental insurance cover a custom mouth guard?

The answer depends on the details of your specific dental plan. Some insurance policies provide partial coverage for nightguards when they are prescribed to protect teeth from grinding damage, while others do not include them as a covered benefit at all. Because plans vary so widely, it’s worth looking at the details before moving forward.

Why Nightguards Are Recommended for Teeth Grinding

Teeth grinding, also known as bruxism, can place a surprising amount of pressure on the teeth and jaw joints. Even though the grinding itself usually happens during sleep, the effects often show up during the day.

Patients with bruxism may experience:

  • Worn or flattened teeth

  • Small cracks or chips in enamel

  • Jaw soreness or muscle fatigue

  • Headaches near the temples

  • Increased tooth sensitivity

A custom nightguard works by creating a protective barrier between the upper and lower teeth. Instead of the teeth pressing directly against one another, the appliance absorbs and spreads out that pressure.

Think of it less as stopping the grinding entirely and more as protecting the teeth from the damage grinding can cause. Over time, this protection can help prevent further wear and reduce stress on the jaw muscles.

How Custom Nightguards Are Different from Store-Bought Guards

Patients sometimes wonder if a store-bought mouthguard could serve the same purpose. Those over-the-counter guards are easy to find and usually cost less upfront, so the comparison makes sense. The main difference comes down to fit and bite balance.

Store-bought guards are usually “boil-and-bite” designs that soften in hot water and then mold loosely around the teeth. While they can offer some cushioning, they rarely match the bite precisely.

A custom nightguard, on the other hand, is made from a detailed impression or digital scan of your teeth. This allows the appliance to fit securely and distribute bite forces evenly across the arch.

In practice, that more precise fit tends to feel more comfortable and makes the guard easier to wear consistently.

How Dental Insurance May Cover a Nightguard

Insurance coverage for nightguards varies quite a bit from plan to plan.

Some dental insurance policies provide partial coverage when a nightguard is prescribed to protect teeth from grinding damage. In those cases, the appliance may fall under major restorative benefits or protective appliances.

However, not every insurance plan includes nightguards as a covered service. Certain plans classify them as elective appliances, which means patients would be responsible for the full cost.

When coverage is available, a few factors often come into play, such as:

  • Documentation of grinding or tooth wear in the dental record

  • Deductibles that must be met before benefits apply

  • Frequency limits for replacing the appliance

Because policies vary, it’s usually helpful to review your benefits ahead of time rather than guessing how coverage might apply.

Why Protecting Teeth Early Matters

Teeth grinding tends to develop slowly, and the damage can accumulate just as gradually. At first, the changes may be difficult to see—slight flattening of the biting edges or small areas of enamel wear.

Over time, though, the pressure from grinding can lead to larger cracks, broken restorations, or chronic jaw discomfort. A nightguard does not stop the grinding itself, but it can help shield the teeth from the long-term effects of that pressure. Many patients also notice that once they begin wearing a properly fitted nightguard, morning jaw tension and tooth sensitivity become less noticeable.
