Custom Fit Mouth Guards vs Boil & Bite Mouth Guards

When it comes to choosing which mouth guard to have you generally have two options a custom-fitted mouthguard or a commercial boil and bite mouthguard.

Custom Mouth Guard

Custom-fit mouth guards provide the best fit and protection possible for your teeth. Custom-fit mouth guards are moulded specifically with your teeth in mind, where are a boil and bit mouthguard comes in a standard shape that you need to mould at home.

Creating a custom-fit mouth guard, normally requires a kit, which will allow you to create impressions of your teeth, which you then send to a dentist for it to be moulded and created to exact dimensions.

It is typical, when getting a custom mouth guard to first receive a kit, which should contain everything you need to create your first impression. You then send the impressions off to the manufacturer, which will then form the finished product. Alternatively, you can go to the dentist, who can provide the service for you.

Boil and Bite Mouth Guards

Boil and Bites and by far the most common type of commercial mouth guard. These a significantly more affordable and available than custom-moulded mouth guards. However, with their price comes features that you don’t get with a custom mouthguard.

Boil and Bites are made out of specialised plastic, that when submerged in hot water will become malleable and will take the form of something until it cools, where the shape will keep. This plastic is what makes boil and bite mouth guards so easy to produce, all the person has to do is follow the manufacturer instructions and they have a well-formed mouth guard that is ready to use quickly.

Most people will choose a boil and bite mouthguard due to their affordability, however a poorly formed boil and bite can damage you teeth rather than protect them, so it’s always important to follow directions closely.[/vc_column_text][/vc_column][/vc_row][vc_row css=”.vc_custom_1521623617379{margin-top: 20px !important;}”] [vc_column][vc_column_text]

The History of the Mouth Guard

While we’re unsure the exact origin of the mouthguard, there are a number of historical references that suggest they were introduced around the turn of the century. The first that seemed to use mouthguards fully was boxing, here boxers originally fashioned a primitive mouthguard out of cotton, tape, sponge and even small pieces of wood. A London dentist named Woolf Krause developed a mouthguard in 1890 to help protect boxers from lip lacerations. These injuries were quite common, especially with primitive mouthguards and often hindered boxing matches.

The original mouthguards from Krause were made from gutta petcha and were actually held in place by clenching the teeth together. Later, Woolf’s son Philip Krause modified the design and remade the mouthguard from Vella rubber. The earliest recording of a mouthguard that resembles’ today’s equipment was in 1916 when Thomas Carlos, a Chicago-based dentist, designed a mouthpiece for U.S Olympian Dinnie O’Keefe. Over the next few years, other dentists claimed to originally design the mouthguard, causing controversy.

Mouthguards became more common during 1927 during a boxing match between Mike McTigue and Jack Sharkey. McTigue was winning the fight, however a chipped tooth, during the match, severely cut his lip and forced him to forfeit the fight. After that match, mouthguards become commonplace during boxing matches and a new era for more modern and affordable mouthguards was born.

A new era

In 1947 an incredible breakthrough was made when in Los Angeles a dentist named Rodney O. Lilyquist used a transparent acrylic resin to form the first splint. This mouthguard was moulded to fit over the upper and lower teeth and was a much more awkward object than today’s modern gumshields. During this time injuries in American Football was around 40% dental.

During the 1950s the American Dental Association started researching and promoted mouthguard benefits for the public. In 1960 the ADA recommended the use of latex in mouthguards in all contact sports. By 1962 all high school football players in the United States were required these to wear these mouthguards.

Presently, mouthguards are required to be used in 29 different sports by the ADA.

Commercial vs Dental mouthguards

Nowadays there is a huge range of mouthguard options available, from different sizes, forms and colours. Modern commercial mouthguards and known as boil and bite and can be purchased from athletic stores and online retailers such as Amazon.

Commercial mouthguards are readily available and you can buy them quickly and fit them efficiently. However, these are not custom and sometimes will not fit a person’s mouth properly, meaning a lack of protection for the wearer.

A dental mouthguard allows a much more customized fit for a fighter, however, it comes at a much steeper price. These mouthguards can also be customized with different colours and prints and will help the person breathe, talk and drink more easily than commercial brands.

Mouth Guard Selection Criteria

Deciding between a commercial boil and bite and a custom mouthguard is only the beginning. When you’re shopping for a new mouthguard there a few more things you need to consider.


Fit is the most important thing when it comes to choosing the right mouthguard. An ill-fitting mouth guard is going to cause more damage than good and a mouth guard that is too tight is going to cause severe discomfort.

If you’re going the custom route, keep a note of any discomfort, over time, especially if you’re still growing, your teeth formation can change over time, which could cause your mouthguard from not fitting correctly.

If you’re going to boil and bit route, make sure you have bought the right size, normally Adult or Youth and the main two sizes, however, it’s always important to be sure. Make sure you follow the instructions carefully for a good fit.


When it comes to commercial mouth guards, the rule of thumb is, the thicker the mouthguard, the more protection it provides, there are the exceptions with products such as SISU, however.

However with a thicker mouth guard, comes breathing and drinking difficulties, so it’s all about choosing the right size for the right job. One factor to consider is your breathing. If you’re struggling to breathe during some heavy sessions, you may need to consider a different mouthguard.


Because mouthguards are made of plastic, this also allows the opportunity for some pretty crazy designs! Dan Hardy’s vampire teeth are a common example when it comes to stylish mouth guards, but there are thousands of different styles. Want a hot pink mouthguard? Easy, want something plainer, like black? No problem. However, you should always choose fit and protection over style. Style is just a nice thing to have, it doesn’t protect you from anything.

Whatever you decided, make sure that you find the best mouthguard for MMA that will fit your mouth well and help protect your teeth.
