Types of Scuba Mouthpieces

The most important thing to consider when you start shopping for a mouthpiece is the type you're interested in.

Fortunately, several styles are designed for the specific needs of divers.

You should be able to easily find a comfortable model that gives you plenty of access to air.

Basic

Basic mouthpieces are the typical ones that come with rental gear, and they'll have two tabs on either side of the unit.

One of the most massive disadvantages to this design is that you'll have to bite down harder on them, reducing their longevity.

However, they are an excellent option for casual divers who don't own personal gear.

As a cost-effective and easily accessible option, they're highly recommended for infrequent divers.

Long Bite

Just as their name suggests, long bite mouthpieces are for people who have longer mouths.

If you've found that traditional mouthpieces force your jaw to overextend, these units are the better option to consider.

They're also far less expensive than some of the other types that you'll find at your local dive shop.

Not every diver will benefit from a long bite mouthpiece, especially if you don't have a long mouth.

You might find they will rub against the inside of your mouth and along your gums.

Above all else, they aren't recommended for divers who have a particularly sensitive gag reflex.

Cushioned

Your comfort is quite essential when it comes to diving, which is where cushioned mouthpieces excel.

With their unique design, you'll have soft tabs that your teeth will grip onto to help cushion them as you bite down.

This style is highly recommended for divers who experience tooth and gum discomfort and tension headaches from biting.

Cushioned mouthpieces are very well-rounded and can be beneficial for professional and casual diving.

You'll spend less time focusing on your mouth being uncomfortable and focus on enjoying your dive time.

Tooth Covering, Winged, and Bridged Mouthpieces

These three types of mouthpieces are the best option for divers who find it challenging to secure their mouthpieces.

They feature a unique design that allows the mouthpiece to fit snugly, whether you're biting down or not.

Also, if you're the type of person who moves around a lot in the water, these can be a preferable option.

Another exciting feature of these mouthpieces is that they grip onto your gums for added security.

However, this can cause them to rub against your gums and the inside of your mouth, causing discomfort.

Some divers prefer these models as they fit securely, but they can be irritating for long excursions.

Custom-Fit

By far, the most popular type of scuba regulator mouthpieces is custom-fit designs.

With these, you'll mold the silicone or rubber to your mouth's specifications, making them unique.

You'll dip them into warm water and hold the mouthpiece as you would while diving to mold it to your teeth.

With a custom-fit, you'll be far less likely to deal with jaw fatigue and discomfort, as they'll fit your mouth the best.

They can also be preferred by people who want a universal mouthpiece before and after dental work.

Interestingly, you can reform the mouthpiece by dipping it back into warm water if your teeth change.

The most significant challenge with custom-fit mouthpieces is they take extra effort to mold to the unique shape of your mouth.

Scuba Regulator Mouthpiece FAQs

1. Do scuba mouthpieces have sizes?

The mouthpiece that you use for your regulator won't come in a specific size, like clothing.

With that said, they will have measurements that you can review to determine if it would sit comfortably in your mouth.

Divers concerned about the unique shape of their mouth could be better off opting for a custom-fit mouthpiece.

Fortunately, most mouthpieces are designed to offer a universal fit, and the material can be trimmed to accommodate your mouth size.

2. Can mouthpieces be used with dentures?

You can easily find inexpensive mouthpieces that are designed for braces, unique mouth shapes, and more.

However, most divers prefer to take their dentures out when it comes to diving, as it can be more comfortable.

Otherwise, you might experience gum irritation from biting down on the device.

3. How long do scuba mouthpieces last?

The majority of high-quality scuba mouthpieces will last up to three years, depending on how often you dive.

You might be able to find the more expensive options for five years, but it's rare.

You'll likely see signs of the silicone wearing away well before the four-year mark.

Final Verdict

Our choice for the best scuba regulator mouthpiece is the Seacure X Type Mouthpiece, as it can be custom molded to your specifications.

You'll also appreciate the high-quality silicone that makes it far more comfortable for extended periods.
