Custom-Fit Mouthguards vs. Boil-and-Bite: which is best for your smile? 

Sporting competitions are about to kick off for another season, so while checking if your boots and shorts still fit, don’t forget to check if your custom mouthguard is over 12 months old and if it still fits correctly.  If it is over 12 months old or is not fitting correctly, it may be time for a new one. 

Wearing a mouthguard during sports helps minimise damage to the face, mouth and jaw from accidental trauma. An accidental hit to the mouth is also just as likely during training as it is during the game, so it’s important to protect your teeth with a custom mouthguard made to fit your teeth perfectly.  

What sports require mouthguards to be worn?

Mouthguards are compulsory for AFL, hockey, boxing and rugby union and league and are recommended for most other sports where there is a risk of direct contact to the face such as soccer and martial arts.  

In our recent Are Media Healthonomics survey we found that while 20% of respondents know that mouthguards are recommended for soccer, only 14% of those who play soccer actually wear one. 

Even accidental elbows in low-impact contact sports can cause facial injuries. Although mouthguards are not mandatory for all contact sports, some sports clubs are dedicated to minimising the risk of dental injuries that may occur during play. These clubs implement the ‘no mouthguard, no play’ mouthguard policy, developed by the Australian Dental Association and Sports Medicine Australia.  

With dental trauma rates as high as 41% in basketball^ and over a third of rugby players^ experiencing injuries, a custom-fit mouthguard is an essential protection for your smile. 

Custom-Fit Mouthguards vs. Boil-and-Bite

To achieve the best protection, mouthguards should be custom-made and professionally fitted by your dentist. During your custom mouthguard fitting your dentist will make an impression of your mouth from which the mouthguard will be made to fit securely around each of your teeth.   

Benefits of custom-made mouthguards

• Provide maximum protection by cushioning teeth, jaws and surrounding soft tissue against impact, absorbing and distributing the force of a hit to the mouth.  

• Protect individual teeth and reduce the likelihood of teeth being knocked out.  

• Reduce soft tissue injury – the teeth being covered by the mouthguard lowers the risk of teeth going through lips, tongues or inner cheeks.  

• A comfortable custom fit helps custom mouthguards stay in place, allowing athletes to speak and breathe more easily.   

• Help to lower the risk of bone fractures and concussions during impact.  

Caring for your custom-made mouthguard  

After each use, rinse your mouthguard with cold water and store it in the provided case, away from direct heat. Regularly inspect your mouthguard for any defects or wear to ensure maximum protection.   

Did you know that mouthguards have a use-by date?

Our recent Are Media Healthonomics survey found that 50% of respondents didn’t know a mouthguard should be replaced every 12 months or sooner if damaged*.  

For children, it’s important to check the fit of their mouthguards regularly, especially when baby teeth are lost, adult teeth erupt, and jaw structures change as they grow. Because of these changes, children typically require a new mouthguard each season. Your dentist can assess your child’s mouthguard at their regular six-month check-up.
