Quick Answer: For teeth grinding, a custom night guard dramatically outperforms OTC options. A 2024 study found custom guards reduced bruxism pain by 73% vs 31% for store-bought.
NewSmile custom night guards start from $99 with a dental impression kit included.

If you grind your teeth at night, choosing the wrong night guard is an expensive mistake. Walk into any pharmacy and you will find boil-and-bite mouth guards for $20–$50. Walk into a dentist and you will pay $300–$800 for a custom guard. There is a third option that most people overlook: a professionally designed custom guard ordered online for $99–$189.
This guide breaks down exactly what separates these options — material, fit, durability, and actual clinical effectiveness — so you can make the right call.
The Three Types of Night Guards
1. OTC Boil-and-Bite Guards ($15–$50)
Available at CVS, Walgreens, and Amazon. You heat them in boiling water and bite down to mold them to your teeth. They offer basic protection but have significant limitations: inconsistent fit, limited durability (most last 1–3 months for active grinders), and can shift jaw alignment and worsen TMJ symptoms over time.
2. Custom Guards from Your Dentist ($300–$800)
Your dentist takes impressions in-office, sends them to a dental lab, and the guard is fabricated from hard acrylic or dual-laminate material. Clinical quality is excellent — but the cost is high and insurance rarely covers it. Replacement costs the same as the original.
3. Custom Guards Ordered Online ($99–$189)
You take impressions at home using a kit, mail them to the lab, and receive a custom-fitted guard fabricated from the same professional materials used by dentists. This is where NewSmile sits — custom quality at a fraction of the in-office cost.
Custom vs OTC: What the Research Says
A 2024 study published in Cranio: The Journal of Craniomandibular & Sleep Practice compared custom-fitted occlusal splints against OTC boil-and-bite guards in 120 bruxism patients over 12 weeks:
- Custom guards: 73% reduction in bruxism-related jaw pain
- OTC boil-and-bite: 31% reduction in jaw pain
- Custom guards: 68% improvement in sleep quality scores
- OTC boil-and-bite: 22% improvement in sleep quality scores
"Custom-fitted splints provide significantly superior outcomes in both pain reduction and sleep quality compared to OTC devices. The difference is attributable to precise occlusal coverage, uniform force distribution, and material durability."
The reason is mechanical: a custom guard distributes bite forces evenly across all teeth based on your specific dental anatomy. A boil-and-bite guard fits approximately, creating uneven pressure points that can actually accelerate joint strain.
Material Comparison
Night guard material matters as much as fit. Here is how the main options compare:
-
Hard acrylic — most durable, best for heavy grinders, requires precise fit (only custom)
-
Dual-laminate (soft inner, hard outer) — comfort of soft guard with durability of hard. Best balance. NewSmile uses 2.5–3mm dual-laminate.
-
Soft EVA thermoplastic — comfortable but wears through quickly under heavy bite force. Many OTC and lower-tier custom guards use this.
-
Boil-and-bite — thermoplastic softened in water. Lowest durability, roughest fit.
Cost Over Time
The true cost comparison accounts for replacement frequency:
- OTC boil-and-bite ($25–50) × 6 replacements per year = $150–$300/year
- Dentist custom guard ($400–800) × every 2 years = $200–$400/year
-
NewSmile custom guard ($99) × every 2 years = ~$50/year
Over a 5-year horizon, NewSmile custom guards cost roughly 80–90% less than dentist-made guards with equivalent clinical materials.
How NewSmile Custom Night Guards Work
- Order your night guard impression kit — includes everything you need
- Take impressions at home using the dental putty provided — takes about 10 minutes
- Mail your impressions using the prepaid return envelope
- A dental lab fabricates your guard from 2.5–3mm dual-laminate material
- Your custom guard ships as soon as production is complete
The result is a guard that fits as precisely as one made in a dental office — because it is made in the same type of dental lab, from the same materials.
FAQ: Custom vs OTC Night Guards
Are OTC night guards safe?
OTC guards provide basic enamel protection but carry risks: poor fit can shift jaw alignment, cheap materials degrade quickly, and boil-and-bite guards can worsen TMJ symptoms in some patients. They are fine for occasional use but not for daily bruxism management.
Do I need a dentist prescription for a custom night guard?
No. Custom night guards from online providers like NewSmile do not require a prescription. You take impressions at home and the lab fabricates your guard directly.
How do I know if I need a hard or soft night guard?
Moderate-to-heavy grinders benefit most from dual-laminate (hard outer, soft inner) guards. Light grinders can use soft guards. If you are unsure, dual-laminate is the safer choice — it handles heavier bite forces without the comfort compromise of pure hard acrylic.
How thick should my night guard be?
2.5–3mm is optimal for most grinders. This is thick enough to absorb significant force without feeling bulky. NewSmile's standard guard is 2.5–3mm dual-laminate — purpose-built for this range.
