SOVA 3D Night Guard | Teeth Grinding Guard for Moderate Bruxism

You've probably tried to ignore it. The tight jaw in the morning, the headache that's there before the day even starts, the dentist mentioning your enamel is wearing down faster than it should. Moderate teeth grinding can cause real damage over time, and a slim guard that barely touches the surface won't cut it.

The SOVA 3D sits at 2.0mm — thick enough to absorb meaningful grinding force, slim enough that you'll actually sleep in it. It's the most popular guard in the SOVA range for a reason: it hits the balance between protection and comfort that most people need. You mould it at home in under five minutes, and if the fit isn't right, you remould it up to 20 times.

Best for

• Adults and children (6+) with moderate teeth grinding or jaw clenching
• People who've tried slim guards and found they wore through too quickly
• Anyone waking with moderate jaw pain, headaches, or tooth sensitivity
• Those wanting reliable nightly protection without the bulk of a traditional mouthguard
• Anyone quoted hundreds by a dentist for a custom splint

What makes it different

• 2.0mm profile — the ideal balance of slim comfort and grinding protection
• Diffusix Technology absorbs and disperses grinding forces across the full guard surface
• Custom-fit at home in minutes using warm water — no dentist visit needed
• Remouldable up to 20 times — adjust until the fit is right
• Open-front design allows natural breathing during sleep
• BPA, latex, phthalate, and PVC free — 120-night durability warranty

How to fit it

Place the guard in hot water until it softens. Bite down firmly to mould it to your teeth, then rinse in cold water to set the shape. Done in under five minutes. If the fit isn't perfect, repeat — you have up to 20 attempts. Wear each night before bed and rinse with warm water each morning.

How the SOVA range compares

Is this the right one?

The 3D suits moderate grinding. If you're a light grinder or first-time user, the slimmer Aero may be more comfortable. If you're waking with significant jaw pain or have chewed through guards before, the SOVA MAX offers heavier-duty protection. For snoring or sleep apnoea, our Somnofit range is worth looking at instead.
