If you grind your teeth at night, you need protection—but should you choose a boil-and-bite night guard (affordable and quick) or a custom night guard (precise and long-lasting)?
This guide breaks down the key differences, pros, and cons of each type, so you can decide which is best for your needs and budget.
Feature | Boil-and-Bite Night Guards | Custom Night Guards |
---|---|---|
Fit | Self-molded at home | Professionally made from dental impressions |
Cost | 20–60 | 150–600 |
Durability | 3–12 months | 2–5 years |
Comfort | Can feel bulky | Thin and tailored to your bite |
Protection Level | Moderate (for mild grinding) | Maximum (for severe grinding/TMJ) |
Adjustments | Can re-mold if needed | Requires dentist visit for adjustments |
✔ Affordable – Great for trying out night guards before investing in custom
✔ Immediate availability – No need to wait for a dentist appointment
✔ Adjustable – Can reheat and re-mold if the fit isn’t perfect
✖ Less precise fit – May feel bulky or slip at night
✖ Wears out faster – Material degrades in months, not years
✖ May encourage chewing – Some people subconsciously bite down on the soft plastic
💡 Best for: Occasional grinders, travelers, or those testing if they need a night guard.
✔ Perfect fit – Made from dental molds for optimal comfort
✔ Superior protection – Distributes grinding forces evenly
✔ Long-lasting – High-quality materials last years, not months
✔ TMJ-friendly – Can be designed to reduce jaw strain
✖ Higher upfront cost (though cheaper long-term)
✖ Requires dentist visit for impressions (or at-home kit)
✖ Takes 1–2 weeks to make
💡 Best for: Frequent grinders, TMJ sufferers, or anyone wanting the best protection.
