You can get a night guard through your dentist’s office, through a mail-order company that sends you an at-home impression kit, or off the shelf at a pharmacy. The route you choose affects the fit, durability, and price, with costs ranging from as little as $15 for a basic store-bought guard to $1,500 or more for a custom one made at a dental office. Here’s what each option involves and how to decide which one makes sense for you.
Start With a Dental Exam
Before you invest in any type of night guard, it helps to know what you’re dealing with. A dentist checks for the telltale signs of grinding and clenching: flattened or chipped teeth, worn enamel that exposes deeper layers, tooth sensitivity, and soreness or tightness in the jaw muscles. They’ll also press along your jaw and face to check for tenderness. This exam matters because jaw pain and tooth wear can have other causes, and a night guard won’t fix all of them. If your dentist confirms bruxism, they can also recommend the right type of guard for how severely you grind.
Getting a Custom Guard From Your Dentist
A dentist-made night guard is the gold standard for fit and protection. The process typically takes two visits. At the first appointment, your dentist takes an impression of your teeth using a tray filled with a soft molding material. You bite into it and hold still for a couple of minutes while it sets. That impression gets sent to a dental lab, where technicians pour it with high-strength stone to create an exact replica of your teeth.
The lab then heats a sheet of thermoplastic material and uses either vacuum pressure or high-pressure lamination to mold it precisely over that stone model. Once cooled, the guard is trimmed, polished, and shaped to fit your bite. At your second appointment, the dentist places the finished guard in your mouth, checks how your teeth come together while wearing it, and makes small adjustments until the fit feels right.
The whole process from impression to final fitting usually takes one to three weeks, depending on the lab. Custom guards from a dental office run $300 to $1,500 or more, but they last significantly longer than cheaper alternatives, typically three to five years with proper care.
Choosing the Right Material
Night guards come in three main material types, and each suits a different level of grinding.
- Soft guards are made from a flexible, rubbery material. They’re the most comfortable at first but wear down fastest, making them a better fit for mild or occasional clenching.
- Hard acrylic guards are rigid and extremely durable. They’re the go-to for heavy grinders because they resist wear and hold their shape over time. They can feel bulky at first, but most people adjust within a week or two.
- Dual-laminate (hybrid) guards have a firm outer shell for durability and a thin soft inner layer for comfort. These work well for mild to moderate grinding and split the difference on lifespan, lasting longer than soft guards but not quite as long as hard acrylic.
Mail-Order Custom Guards
Direct-to-consumer companies offer a middle ground: a custom-fitted guard without the dental office price tag. These typically cost $95 to $175. The company mails you an impression kit, you take your own molds at home, and send them back. A lab fabricates your guard and ships it to you, usually within two to three weeks.
The at-home impression process is straightforward but requires some care. You’ll get trays and two colors of putty that you knead together quickly (it starts hardening within about 30 seconds). Roll the mixed putty into a coil, press it into the tray, then push the tray up over your teeth with your fingers until the putty reaches your gumline. Hold completely still for about three and a half minutes. Don’t bite down into the tray or wiggle it. When the time is up, pull the tray straight off without twisting.
The most common mistakes are moving the tray while the putty sets, not covering the back molars completely, or pressing so hard that your teeth push through to the plastic tray itself. A bad impression means a bad fit, and most companies will send a replacement kit if your first attempt doesn’t work out. The resulting guard won’t be adjusted in person by a dentist, so the quality of your impression is everything.
Over-the-Counter Options
Pharmacies and online retailers sell two basic types. Stock guards ($15 to $40) come in preset sizes and offer the least precise fit. Boil-and-bite guards ($25 to $60) let you soften the plastic in hot water, then bite into it to create a rough mold of your teeth.
Both are inexpensive and available immediately, which makes them tempting. But a guard that doesn’t fit well can cause soreness in your teeth, gums, or jaw. Cleveland Clinic notes that store-bought guards are less effective than custom options for protecting against grinding. They also wear down much faster, often within six months to a year. If you’re using an over-the-counter guard as a short-term solution while you arrange something better, that’s reasonable. As a long-term strategy for significant grinding, they fall short.
What Insurance Covers
Most dental insurance plans cover night guards that are labeled medically necessary for bruxism. Your dentist’s office handles the billing using specific procedure codes that distinguish between hard, soft, and partial-arch guards. Coverage typically falls under your plan’s major services category, which means it counts against your annual maximum benefit.
There are exceptions. Discount dental plans, some HMOs, and policies with cosmetic-only riders often exclude night guards. If your guard is classified as a TMJ splint rather than a standard occlusal guard, coverage rules may differ. Call your insurance before your appointment and ask specifically whether occlusal guards for bruxism are a covered benefit, and what percentage they’ll pay after your deductible.
Making Your Night Guard Last
A custom night guard can protect your teeth for years if you take basic care of it. Rinse it with cool water every time you take it out in the morning. Hot water can warp the plastic, so always stick with cold or room temperature. You can brush it gently with a soft-bristle toothbrush and toothpaste, or give it a quick rinse in mouthwash to kill bacteria. Don’t soak it in mouthwash for extended periods, as that can damage the material over time.
Store it in the protective case it came with. Leaving it on a nightstand or in a drawer exposes it to dust and bacteria, and pets seem magnetically attracted to chewing on them.
When to Replace Your Guard
Even with good care, every night guard eventually wears out. Watch for cracks, chips, or spots where the material is visibly thinner. A guard that once fit snugly but now feels loose has lost its shape. If you start hearing grinding noises at night again, or if jaw pain and tooth sensitivity come back after a period of relief, the guard is no longer doing its job. Yellowing and persistent odor that won’t clean off are also signs it’s time for a new one. Hard acrylic guards generally last the longest, with soft guards needing replacement sooner. Plan on replacing a professionally made guard every three to five years on average.
