Thai Boxing Mouthguard Buying Guide

Having a mouthguard is absolutely essential when you’re competing, sparring, or practicing clinching. A good mouthguard can prevent injuries to your mouth and teeth that could be absolutely devastating. Losing a tooth is not only painful, but it can cost thousands of dollars in repair. These types of injuries and costs can be prevented with proper gear.

If you’re training without a mouthguard, then you not only run the risk of losing or chipping a tooth, but a lot of other head injuries that you might not have even thought of.

Your mouthguard helps protect your jaw, your neck, your tongue and gums and even why to wear a mouthguard infographicreduces the risk of a concussion. By having the guard secured between your teeth, you put a cushion that reduces impact pressure in all of these areas. Plus, it is much more difficult to bite your tongue if you have your teeth covered with a guard.

Training without a mouthguard is irresponsible, so make sure you buy the right one for you. There are a few things to consider when purchasing a mouthguard. You want to make sure that the fit is right, that the quality is enough to keep you safe and whether or not you have any specific things to consider for your mouthguard (e.g. if you wear braces).

Find the right mouthguard is crucial to your training, so make sure that you have one that is exactly what you need.

Types of Mouthguards

Before you choose a mouthguard, make sure you are buying a high-impact product. There are mouthguards out there for a lot of things, and you want to have one that is designed to take impact opposed to one that is supposed to simply stop you from grinding your teeth.

A high impact mouthguard will ensure that you are protected when you take a hit to the mouth. There are two main types of high-impact mouthguards that you can buy. Either will work, so it will depend on which one you prefer and which one fits your budget.

Boil-and-Bite Style (Best Value and Protection)

 As the name suggests, this mouthguard requires that you mold it by boiling the product in hot water until the plastic is soft and then placing it in your mouth to make an impression of your teeth so it will fit your mouth comfortably. These mouthguards are relatively inexpensive, can be made at home and will do a decent job of protecting your teeth.

These take a relatively short time to make and they won’t break your budget if you buy one. The biggest downside is that you have to make it at home to fit your mouth, so if you don’t feel comfortable doing this or you think you might mess it up, then you want to opt for something different.

Also, if they don’t fit exactly right, they can come out of your mouth quite easily. This is very important for Thai boxing, because you don’t want your mouthguard to come flying out every time you take a hit to the face.

Custom Style (Most Expensive)

A custom mouthguard is created from a mold of your teeth. They can be expensive, especially because you will need someone to make the mold of your mouth and then make the guard from that mold. However, these mouthguards offer the most protection. They cannot be easily expelled from your mouth, even with your tongue or with a solid hit.

They lock onto your teeth, are made from a thicker and more protective plastic and are also easier to speak and breathe with. Unlike a boil-and-bite guard, a custom mouthguard locks into place, so you don’t have to suck on it to keep it on your teeth.

You will have a much easier time communicating and being comfortable while you’re training or competing. The biggest downside to a custom mouthguard is the price and the time it takes to make one.

How do mouth guards work?

Mouth guards can save much more than simply a tooth. If you are still in doubt about getting one, read the ways in which it can prevent a brain concussion and more.

An impact or a direct blow can send shockwaves running through your jaw line up to the skull. If you happen to experience a direct impact to the front of you teeth, you might have a fracture. If the impact is extreme, it might even lead to a brain concussion.

This is where mouth guards have a role to play. They are designed in a way so as to absorb shock effectively. It distributes the impact of the blow evenly. This helps in prevention of injuries at any one particular place. Mouth guards come along with outer cushions that also prevent upper and lower jaws from colliding.

Our Final Thoughts of Protecting You Face and Jaw

Before you even begin training Muay Thai, you should have a proper mouthguard. Nothing is more important than your safety, and having the right guard could mean the difference between a strike to the face that just shakes you a bit and a broken tooth or jaw. We recommend that you look hard and long at the types of mouthguards available before you choose which one to buy.

It is important that you recognize that you will need a mouthguard for high impact. Don’t buy a cheap, stock mouthguard that is for sleeping or low-impact sports. You will be taking punches and kicks to the face, and a flimsy mouthguard will not offer you the protection you need.

Choose either a boil-and-bite mouthguard or a custom mouthguard to ensure that you have the best protection for you. There are a lot of styles and colors for either kind, so feel free to find something that fits your personality. Be smart when buying. This is one item of your gear that it is not worth going the cheapest route on.
