You walk into your dentist’s office with jaw pain, headaches, or worn-down teeth — and the solution they give you is a night guard. Then comes the gut punch: $500, $700, sometimes over $1,000 for a piece of plastic. Insurance usually won’t cover it (see our full guide: [Does Insurance Cover a Dental Night Guard?], leaving you wondering: why are dentist night guards so expensive? And is there a difference between paying your dentist and ordering a custom guard online?
At Sentinel Mouthguards, we’ve worked with thousands of people who felt the same frustration — and found out there’s a better way. Before you spend a small fortune at the dentist, here are 5 reasons to think twice (and what to do instead).
This article is part of our [Complete Guide to Custom Night Guards].
1. Dentist Overhead Costs Drive Prices Sky High
Your dentist isn’t making every night guard in-house. Most impressions are sent to a third-party dental lab — the same type of lab we run. By the time you pay, you’re covering not only the lab fee but also your dentist’s overhead costs: staff salaries, rent, expensive equipment, and markups. That’s why a guard that costs $100–$200 to make suddenly costs you $500–$1,000.
2. Premium Materials & Care (But Often More Than You Need)
Yes, dentists use safe, durable materials — but so do we. In fact, our guards are made from the same FDA-approved EVA and copolyester used in dental offices. The truth? You’re not paying for “better materials” — you’re paying for the middleman.
3. Convenience & Time Delay
A dentist-made guard can take weeks between appointments, lab turnaround, and adjustments. Meanwhile, you’re still grinding your teeth at night. Ordering online means you can skip the appointments and get your guard crafted in just days — without leaving home.
4. Modern At-Home Options Put You in Control
With today’s technology, at-home impression kits are simple and accurate. You take your mold at home, mail it back, and our lab creates a guard just like your dentist’s — without the markup. It’s the same dental-grade product for a fraction of the cost.
5. Pricing Transparency & Satisfaction Guarantee
When you buy through a dentist, you rarely see the breakdown of what you’re paying for. With Sentinel, it’s simple: clear pricing, no hidden fees, and a satisfaction guarantee. If your guard doesn’t fit, we’ll make it right.
✅ What to Consider Instead
Instead of overpaying at the dentist or settling for a flimsy drugstore guard, look for:
-
FDA-approved materials (EVA or copolyester — not PVC or cheap acrylics)
-
A trusted U.S.-based lab (with reviews and transparency)
-
Guarantees & replacement policies (so you’re not left stuck if it doesn’t fit)

Quick FAQs
Are online night guards safe?
Yes — if made from dental-grade, FDA-approved materials in a professional lab. Sentinel guards use the exact same materials dentists use.
Can a guard be too cheap?
Absolutely. OTC $20 guards often use low-grade plastics, wear out in months, and can even trigger allergies. Custom is the safer, smarter option.
How long will a Sentinel guard last compared to a dentist guard?
The same. Soft guards: 6–12 months. Dual laminates: 1–2 years. Hard guards: 2–5+ years.
Our guards are made from FDA-approved EVA and copolyester — the same materials we cover in our [Night Guard Safety Guide].
