Review: Finally a reasonably priced mouth guard that fits a childs mouth and will protect their teeth - I have four children aged 14-7 years who all play rugby or hockey. About three years ago after trying every brand of boil and bite mouth guard I decided that the only way to really protect their teeth was to pay out £45 each for a custom made mouth guard at the beginning of the season. This is expensive but also frustrating if they loose a tooth halfway through the year. The problems I have found with the boil and bite style mouth guard are they don't seem to fit a child's mouth, they either don't mould enough to the mouth shape or they bite right through them while fitting. I have never found one that passes the test of staying in place when the child opens its mouth. It took me a while to understand that this is the crucial thing with a mouth guard, its unlikely that the mouth will be closed at the time of impact and if the mouth guard doesn't stay in place when the mouth is open it offers no protection to the teeth. The other big factor is comfort, children won't' wear a mouth guard that hurts them or makes them gag. I have often witnessed children tucking their mouth guard into their sock as play begins. Recently my youngest daughter started playing hockey. I had neither the time or the justification for a £45 custom fitted mouth guard so I decided to resort to the boil and bite type. I carefully read the reviews and ordered a strawberry flavoured £10 one. It arrived and the case to keep it in was the most useful thing about it. Despite multiple tries with boiling water it didn't stay in place and was clearly too big. It fitted my 42 year old mouth a treat despite being the junior size. I was ready to give up and pay for a fitted one. Then I discovered the Sisu mouth guard. There were only five reviews and it was £16. If it didn't work I was now halfway to a fitted mouth guard. But reading the reviews and the specifications I decided to give it a try. Yippee! its great. Surprisingly its arrives as a flat, thin piece of plastic but a quick dunk in hot water and it moulds perfectly to the mouth. We had to have a couple of goes to get it right but it is now perfect. A light weight, comfortable custom fitted mouth guard which stays in place when the mouth is open and as an extra bonus it comes in cool colours. My only criticism is it doesn't come with a proper plastic case but then I have loads of those from all the discarded, poorly fitting mouth guards I have tried over the years! And if that's not enough they claim that it can be refitted if a tooth falls out by putting it back in hot water and remoulding. Can this really be true? I haven't had to try yet but will certainly get back to you if it is.
Review: Fantastic mouth guard - My 10 year old son does BJJ and this mouth guard is perfect for rolling sessions in class and for competition use. Extremely low profile, enabling him to speak whilst still wearing the mouth guard. The ability to remold it numerous times is also super useful for kids whose teeth are still growing. Highly recommended.

### ⭐⭐⭐⭐ Different but good
*by A***N on 24 June 2025*

Can be difficult to fit. It feels strange at first due to the hard texture but it works well and is less intrusive because of the compact design.
