Why Night Guard Materials Matter
Grinding your teeth at night, known as bruxism, affects about 8% of adults. Without protection, bruxism can damage your teeth, causing cracks, wear, or even tooth loss. The material of your night guard impacts its:
- Comfort
- Durability
- Effectiveness in protecting your teeth
Choosing the right material ensures your night guard works well and feels good.
Types of Night Guard Materials
There are three main types of night guard materials:
1. Hard Night Guards
Made from acrylic or zirconia, these are rigid and highly durable.
Best for:
- Heavy grinders
- Those needing long-lasting protection
- People with dental restorations (e.g., crowns)
Not ideal for:
- Those preferring soft materials
- People with a sensitive gag reflex
A custom hard night guard can last 3-5 years or more.
2. Soft Night Guards
Made from dental-grade silicone or EVA (ethylene-vinyl acetate), these are soft and cushioned.
Best for:
- People with jaw pain (TMJ disorders)
- Light to moderate clenchers
- First-time night guard users
- Children with bruxism
Not ideal for:
- Severe grinders
- Those needing long-term durability
A custom soft night guard for teeth grinding is comfortable but may need replacement every 6-12 months.
3. Hybrid Guards (Dual-Laminate)
These combine a soft inner layer with a hard outer shell, offering both comfort and strength.
Best for:
- Moderate to heavy grinders seeking comfort
- People with both grinding and jaw pain
- Those unsatisfied with fully hard or soft guards
The night guard with soft inside hard outside is a popular choice among dentists.

Hard vs. Soft Night Guards: Which Should You Choose?
Here’s a comparison:
Feature | Hard Guards | Soft Guards | Hybrid Guards |
---|---|---|---|
Durability | 3-5+ years | 6-12 months | 2-3 years |
Comfort | Takes time to adjust | Immediate comfort | Comfortable soon |
Protection Level | Very high | Medium | High |
Cost | $$$$ | $$ | $$$ |

People with allergies should request hypoallergenic materials.
