How mouth guards can prevent mouth injuries

Sponsored content

Sports mouthguards are like crash helmets for your teeth. Mouth guards are strongly recommended to prevent tooth damage or loss, especially if playing a contact sport. They reduce the risk of cuts to the lip, mouth and tongue, jaw fractures and concussion.

Mouthguards are U-shaped pieces of plastic that fit between the upper and lower teeth, protectively moulding around the upper teeth.

Custom-made mouthguards by your dentist provide an excellent fit and protection, but are much more expensive than an off-the-shelf product. If the off the shelf product is properly fitted, the mouth formed (thermal) guard can virtually match the efficacy and comfort of the custom-made guard.

Boil-and-bite mouth guards are made of a thermoplastic material that softens when boiled and will then mould around the teeth when bitten down on. Boil-and-bite mouth guards are a good choice for children who are losing and growing teeth and have an ever-changing bite.

Elastoplast Sports Mouthguards are high-quality thermal guards that are:

  • durable
  • inexpensive
  • easy to fit using the boil-and-bite method

How to Fit a Mouthguard

A correct fit is essential to ensure your mouthguard is effective.

Step 1: Select the correct size – Junior (under 10 years), Youth (11-15 years) and Adult (16 years and over). (Please note that these ages are approximate as mouth sizes can vary).

Step 2: Place the Elastoplast Sport Mouthguard over the upper teeth to test for size.

Step 3: If too large, trim back using scissors until a comfortable size is achieved.

Step 4: Practise pressing the mouth guard firmly to the roof of the mouth with the tongue whilst biting down gently.

Step 5: Place the mouth guard in near-boiling water for 10 seconds. Remove with a large spoon and shake off the excess.

Step 6: Insert mouthguard immediately into position and bite firmly, but gently, to obtain an even bite. The guard will feel warm, but will not burn the mouth.

Step 7: Whilst in this position, suck the guard into place by exerting pressure with the tongue against the roof of the mouth.

Step 8: Mould the guard around the side of the teeth with the forefinger to ensure a tight fit.

Step 9: If the fit is not right, repeat until it feels correct.

    These high quality yet economically friendly boil and bite options sound like a great idea! My, now 10, son did contact sparring through Taekwondo for a few years and he had a mouthguard that we got from the supermarket. It never seemed to fit him properly and he hated wearing it, although he always did for safety. Having these instructions, that are listed above, back then would have made fitting the mouthguard a lot easier I’m sure!

    Our son has needed mouth guards for rugby (rippa, touch and tackle) for the past four years. I used mouthguards when I played sport as a child and I completely forgot about the boil and bite technique! Will definitely remember it for coming years for the kid’s sports ūüôā

    My son used a mouth guard when he played hockey, it was good that we had a friend who played rugby as a teen and he was able to mold and fit it comfortably. They are great to help prevent mouth injuries in our young ones.

    My son played soccer and did Tae Kwon Do so his mouthguard was very well used and I am so glad it was, I would hate so see what mouth injuries he would have suffered without it!

    My daughter would definitely be using a mouthguard when she played sports! Very important. I played netball and soccer when I was younger and I got smacked in the gob a few times! Really have to protect your teeth and jaw, the boil and bite mouth guards are really good.
