Night Guard vs Sports Guard: What's the Difference?

Design difference

• Night guard: hard or semi-hard, thin (1–2 mm), fits one arch (usually upper). Designed to cushion grinding/clenching forces.
• Sports guard: thicker (3–5 mm), softer material, covers one arch plus extends over gums. Designed to absorb blunt impact.

Night guards — purpose and types

Purpose

• Protect teeth from grinding wear
• Protect restorations (veneers, crowns)
• Reduce jaw muscle soreness from clenching
• Prevent fracture of cracked teeth

Types

Hard acrylic (recommended for most)

• Hard, distributes force evenly
• Barely perceptible once adapted
• Lasts 3–5 years

Soft silicone

• More comfortable initially
• Can encourage clenching in some patients
• Typically lasts 6–18 months

Dual-laminate (hybrid)

• Soft inside, hard outside
• Good compromise for first-time wearers

Cost in Dubai

Sports guards — purpose and types

Purpose

• Absorb impact forces in contact sports (football, rugby, martial arts, boxing)
• Protect against chipped or knocked-out teeth
• Cushion against tongue bites during impacts
• Reduce concussion risk (some evidence)

Sports that need them

• Football, rugby, basketball, hockey
• Martial arts, boxing, MMA
• Motocross, cycling (off-road)
• Skateboarding, BMX
• Wrestling, lacrosse

Types

Stock (boil-and-bite)

• AED 30–80
• Poor fit, falls out easily
• Only for very casual use

Custom-fit

• AED 600–1,200
• Dentist takes scan or impression, lab makes the guard
• Tight fit, stays in during heavy impact
• Allows clear speech and breathing

Can I use one for both?

No. A night guard is too thin to absorb impact; a sports guard is too thick to wear all night. Active lifestyle patients who grind need one of each.

Custom vs over-the-counter — the quality gap

For sports that put any real impact on the face, a custom guard is significantly more protective. Studies show custom guards reduce dental injury risk by 50–80% over stock guards. For a child doing twice-weekly football, the AED 800 custom guard is the best insurance you can buy.

Care

• Rinse with cool water after each use
• Clean gently with mild soap weekly
• Store in a vented case (no airtight — growth of bacteria)
• Replace sports guards annually or after any significant impact
• Bring nightguards to hygiene visits for professional cleaning

When to replace

Night guard

• Visible wear patches on the biting surface
• Cracks or holes
• Doesn't fit snugly any more
• Typically 3–5 years

Sports guard

• Any tear or puncture
• Loose fit
• After any impact that cracked or deformed it
• Typically annually for active athletes
