Mouth Guards for Combat Sports: What Gyms Should Stock

Published 2026 · 6 min read

Mouth guards are a small line item on a wholesale order sheet but a high-repeat-purchase product for any boxing, MMA, or BJJ gym pro shop. Here is what to evaluate before placing a bulk order.

1. Single vs Double Mouth Guards

Single mouth guards cover the upper teeth only and suit boxing, Muay Thai, and general sparring. Double (dual-arch) mouth guards cover both upper and lower teeth and are typically required for MMA competition where jaw protection from both directions matters.

2. Material: EVA vs Silicone

EVA (ethylene-vinyl acetate) is the industry standard — it is boilable, moldable, and offers reliable shock absorption at a low cost per unit. Silicone options exist but are less common in wholesale gym supply due to higher cost and less consistent moldability.

3. Boil-and-Bite vs Custom-Fitted

Boil-and-bite mouth guards are the standard wholesale offering — the wearer softens the guard in hot water and bites down to form a fit. This covers the vast majority of gym and retail demand. Custom-fitted (lab-molded) guards are a premium, higher-cost category usually sold separately through dental providers rather than gym pro shops.

4. Thickness and Impact Protection

Thicker guards (4mm+) offer more impact absorption but can affect breathing and speech comfort. A mid-range thickness is generally the best-selling option for gyms stocking a single SKU, balancing protection with wearability.

5. Hygiene and Case Options

Every mouth guard should ship with a ventilated hard case to prevent bacteria buildup between uses. For pro shop resale, a branded case adds a visible touchpoint for your gym or brand logo beyond the guard itself.

6. Custom Branding for Gyms and Retail

Mouth guards and their cases can be private labeled with:
