Quick Answer
If you've ever been quoted $400 to $800 for a custom night guard at your dentist's office, you're not alone.
At first glance, a night guard can seem like an expensive piece of plastic. But the price reflects much more than the material itself.
When you purchase a professionally made custom night guard, you're paying for:
- A custom fit based on your teeth
- Dental-grade materials
- Skilled fabrication
- Precision trimming and polishing
- Quality control
- Protection against costly dental damage
The good news? While custom night guards are worth the investment for many people, they don't necessarily have to cost hundreds of dollars.
If you're still deciding whether a custom night guard is worth it, our Choosing the Best Custom Night Guard guide can help you compare your options before you buy.
Why Do Dentists Charge $400–$800 for a Night Guard?
There isn't one single reason.
Several costs contribute to the final price.
1. The Dental Exam
Before recommending a night guard, your dentist typically performs an examination.
They may evaluate:
- Tooth wear
- Jaw pain
- Bite alignment
- Existing dental work
- Signs of teeth grinding (bruxism)
Part of your fee helps cover the dentist's time and expertise.
2. Taking Dental Impressions or Digital Scans
Your guard must match your teeth precisely.
Your dentist may use:
- Traditional dental impressions
- A digital intraoral scanner
Either method requires equipment, staff time, and materials.
3. Dental Laboratory Fabrication
Contrary to what many people assume, most dentists do not manufacture night guards in their office.
Instead, impressions are sent to a dental laboratory where technicians fabricate your appliance.
The process often includes:
- Creating a model of your teeth
- Heating dental-grade thermoplastic
- Pressure or vacuum forming
- Trimming
- Polishing
- Final inspection
Each guard is made specifically for one patient.
4. High-Quality Dental Materials
Custom night guards aren't made from ordinary plastic.
Most professional laboratories use medical or dental-grade thermoplastics designed to withstand nightly use while remaining comfortable.
Different materials are used depending on whether the patient has:
- Mild grinding
- Heavy grinding
- Jaw clenching
- TMJ symptoms
- Tooth sensitivity
The material itself represents only a portion of the total cost—but quality matters.
Different materials affect comfort, durability, and lifespan. If you're unsure which material is right for you, read our guide comparing soft vs. hard night guards.
5. Dentist Overhead
Perhaps the biggest factor many patients don't consider is overhead.
Dental offices must cover expenses such as:
- Office rent
- Clinical staff
- Sterilization
- Equipment
- Insurance
- Administrative personnel
- Utilities
- Continuing education
These business costs are built into many dental procedures—including custom night guards.
Does a More Expensive Night Guard Mean It's Better?
Not necessarily.
Higher prices don't automatically mean higher quality.
Two custom night guards may be made from similar dental-grade materials in comparable laboratories, yet differ significantly in price depending on:
- Where you buy
- Business overhead
- Distribution model
- Warranty
- Customer service
This is why consumers increasingly compare dentist-provided guards with direct-to-consumer custom laboratories.
People who grind heavily often wear through thin appliances much faster.

Why Are Cheap Night Guards So Inexpensive?
Boil-and-bite guards often cost between $20 and $50.
They can work as a temporary solution for some people, but they're very different from custom-made appliances.
Common drawbacks include:
- Generic fit
- Bulkier design
- Less comfort
- More movement during sleep
- Shorter lifespan
- Reduced protection for heavy grinders
Because they're mass-produced, manufacturing costs are much lower.
Are Custom Night Guards Worth the Money?
For many people, yes.
A properly fitting custom night guard may help protect your teeth from:
- Excessive enamel wear
- Chipped teeth
- Cracked dental restorations
- Broken crowns
- Tooth fractures
Considering that repairing one damaged tooth can cost hundreds—or even thousands—of dollars, a custom night guard may help prevent much more expensive dental treatment later.

Final Thoughts
Although custom night guards may seem expensive at first, much of the cost reflects the expertise, materials, and craftsmanship required to create an appliance that fits your teeth precisely.
If you're comparing options, remember that price alone doesn't determine quality. Consider factors such as the manufacturing process, materials, warranty, customer support, and whether the appliance is custom made specifically for your smile.
