Different Types of Scuba Mouthpieces
Standard/Basic
You will find basic and standard sized mouthpieces are the kind that comes with cheaper regulators and rental gear. As they generally feature two very ordinary tabs, you need to bite down a lot harder on them than other options, which means they don’t last nearly as long as others.
If you don’t dive as regularly as you would like, this might be a cost-effective option, though if you are going to be diving regularly, you might want to invest in something a bit better.
Cushioned Mouthpieces
As the name suggests, these mouthpieces have soft grips over the tabs you bite down on to increase the level of comfort and protect them against bite-through. Although a tiny bit pricier than standard models, these are extremely comfortable and allow you to concentrate on enjoying your time under the sea.
Long Bite Mouthpieces
Long bite mouthpieces (that often feature textured tabs too) offer you a bit more to bite into. Although many divers swear by them, if you don’t have a particularly long mouth, you may find they are not the most comfortable to use.
As a start mouthpiece, they are ideal because they are not usually very expensive.
Tooth Covering, Winged, and Bridged Mouthpieces
All these mouthpieces, bridged, winged and tooth-covering are designed to help secure your mouthpiece snugly in place. These are ideal for divers who like to or are in the habit of twisting around a lot. One issue with bridged-style mouthpieces is that the tabs are connected and when they rub on the inside of your mouth, they can be uncomfortable.
Similarly, with tooth-covering and winged-style mouthpieces, they grip onto your gums and can rub against the insides of your mouth. However, if you find one that fits you well, then they are worth it.

Custom Fit Mouthpieces
A customized mouthpiece is one that you can trim down easily to the length that suits your mouth best. You then need to place it in boiling water and then bite down on it to form a mold of your bite shape.
It can be a bit fiddly when you are first using one, but when you get it right, you have a mouthpiece almost perfectly molded to fit the size and shape of your mouth, making it incredibly comfortable to use.

Frequently Asked Questions about Scuba Mouthpieces
What is the mouthpiece called scuba diving?
The mouthpiece used in scuba diving is called a diving regulator mouthpiece. Regulator mouthpieces allows scuba diver to breath in air from their tank.
There are di different types of dive regulator mouthpiece. Some are made from basic silicone in a universal shape while others are a moldable scuba mouthpiece that creates a custom fit.
Is it worth buying your own scuba gear?
Buying your own scuba gear is an investment but one that is worth it. Most scuba diving equipment is meant to have a snug fit and can feel quite uncomfortable when it doesn’t suit your face and body just right.
Over time, buying your own gear will prove more affordable if you are a frequent diver. On the other hand, if you only occasionally dive then it might make more financial sense to rent the equipment.
Why do scuba divers wear snorkels?
Scuba divers mainly wear snorkels to be able to breathe at the surface level without using their air supply. This saves more of the air supply for when they are deeper underwater.
How do you change a regulator on a mouthpiece?
- Carefully cut off the zip tie on the old mouthpiece using a side cutter. Slide the cutter under the zip tie and then snip without damaging the mouthpiece or regulator.
- Pull off the old mouthpiece from the regulator.
- Slide the new dive mouthpiece into the same position.
- Take a zip tie and secure it exactly where the mouthpiece ends and the rest of the regulator tube starts.
- Pull the piece where the zip tie feeds through to left or right side of the mouthpiece so that it doesn’t bother your field of vision.
- Secure the zip tie tightly but it should not be so tight that the mouthpiece shape changes.
- Using the side cutter, cut off as much of the excess zip tie as you can.
- If the part where the zip tie feeds through feels too large, you can cut off a small piece using a box cutter. Make sure you are not loosening the zip tie by doing this.
