Boxing Gum Shield FAQs

What is the best gum shield for boxing?

The best gum shield depends on your budget and training level. For most boxers, a quality boil and bite guard from Opro or Adidas provides excellent protection at an affordable price. For those who want maximum comfort and breathability, the SISU slim-fit guard is a popular choice as it allows easier breathing and speaking during training. For the highest level of protection and fit, a custom-fit mouthguard is the professional choice.

How do I fit a boil and bite gum shield?

To fit a boil and bite gum shield, bring a pan of water to the boil and remove from the heat. Submerge the gum shield for the time specified in the product instructions (usually 30–60 seconds). Remove carefully, allow to cool for a few seconds, then place in your mouth and bite down firmly while pressing the shield against your teeth and gums with your fingers and tongue. Hold for the recommended time, then remove and cool in cold water. Check individual product instructions as fitting times vary by brand.

What is a SISU gum shield?

SISU is a brand known for its innovative slim-fit mouthguards, which are significantly thinner than traditional boil and bite guards. Despite their low profile, SISU guards provide strong protection and allow easier breathing, drinking and communication during training. They are popular with experienced boxers and fighters who find traditional guards bulky or uncomfortable. SISU guards are available in junior and adult sizes.

Do children need a special gum shield for boxing?

Yes — children should use a junior-sized gum shield designed for smaller mouths and developing teeth. Junior gum shields are available in smaller sizes and are easier to fit and mould for younger boxers. A properly fitted gum shield is essential for any child taking part in sparring or contact boxing sessions. Check individual product listings for recommended age ranges, or contact us for advice.
