If you grind your teeth at night—what dentists call bruxism—you’re not alone. Millions deal with chipped enamel, jaw tension, and even migraines, all caused by nighttime grinding or clenching. Left unchecked, it can cost you thousands in dental repairs. That’s where affordable night guards for grinding come in: low-cost, high-impact solutions that protect your teeth while you sleep.
Contrary to what some believe, you don’t need a $400+ guard from your dentist to get relief. Today’s market offers reliable, custom-fitted guards under $100—without sacrificing quality or comfort.
This guide ranks the top 5 night guards for grinding under $100, based on comfort, material, customization, and customer satisfaction.
What to Look For in an Affordable Night Guard
1. Material Quality
Go for BPA-free, FDA-approved materials. Whether you prefer soft or firm, make sure the night guard is safe for prolonged oral use.
2. Custom Fit
Boil-and-bite guards can work short-term, but a custom-fit night guard made from your dental impression provides better protection and comfort.
3. Durability
Affordable doesn’t mean disposable. Look for reviews or descriptions that mention how long the guard lasts under regular grinding.
4. Return Policy & Guarantee
Even under $100, a night guard is an investment. Opt for brands offering at least a 30-day satisfaction guarantee.

Best for: Mild to moderate grinding, all-day comfort
This slim, soft night guard is made from flexible, BPA-free materials and custom-moulded for your smile.

The discreet design ensures clear speech and a relaxed fit without jaw fatigue.

2. Plackers Grind No More Dental Night Protectors
Price: ~$22 (pack of 10)
Best for: Very short-term use or travel backup
Disposable, one-size-fits-most guards designed for convenience. No boiling or molding required. They’re ready to go out of the box—but they only last about 3 nights each.
- Extremely low price
- Not custom-fit
- Lacks long-term durability
3. DenTek Professional-Fit Maximum Protection Night Guard
Price: ~$25
Best for: Beginners trying their first night guard
This over-the-counter guard offers a decent fit through a boil-and-bite process. It’s thicker than some people prefer, but good for strong grinders who want a quick solution.
- Affordable and accessible
- Includes forming tray for better fit
- Not as slim or durable as custom-fit options
4. Oral-B Nighttime Dental Guard with Scope Flavor
Price: ~$30
Best for: Those who want a minty fresh guard experience
Oral-B adds a twist with Scope-infused material, offering freshness alongside grinding protection. The fit is boil-and-bite, so not custom, but it’s one of the most reviewed OTC guards on the market.
- Mint flavor
- Trusted brand
- Not a long-term solution for heavy grinding
5. Neomen Professional Dental Guard
Price: ~$20–$30 (set of 4)
Best for: Budget-conscious families or couples
This package includes multiple guards in various sizes, which is great if you're unsure what fit works best. Like other boil-and-bite styles, these aren’t custom-moulded from impressions, but they’re solid for light to moderate use.
- Multiple guards included
- Re-moldable
- Less protection than dentist-grade options
Why Slim Fit from DentalNightGuard Stands Out
While all five night guards provide some level of protection under $100, the Slim Fit Night Guard from DentalNightGuard is the only one on this list that:
- Offers a true custom fit based on your dental impression
- Uses dentist-grade materials without a clinic markup
- Is designed for dual use—night and day
- Comes with a 100% satisfaction guarantee and free shipping
It blends affordability and professional quality in a way that OTC options just can’t match.
