**3. ** **Dry Suit Mouthpieces:** Dry suit mouthpieces are designed for use with dry suits, which keep divers warm and dry in cold water conditions. These mouthpieces have a special feature called a ""dry valve"" that prevents water from entering the mouthpiece and lungs. The dry valve is a small, one-way valve that opens only when the diver inhales.

Just like a pair of shoes, a scuba mouthpiece needs to fit correctly to be comfortable and effective. A mouthpiece that's too small or too large can lead to a variety of problems, from discomfort and fatigue to air leaks and even a weakened grip on your regulator.
**2. Lip Seals:** These are the soft, flexible rubber parts that seal around your lips, creating a tight seal that prevents air from leaking out during breathing. Lip seals are often made from a comfortable, hypoallergenic material that minimizes irritation and discomfort.
Here's a brief timeline of some key milestones in mouthpiece innovation:
* **Ergonomic Shapes:** Mouthpiece designers began to focus on ergonomics, creating bite blocks that were contoured to the natural shape of the mouth. This significantly reduced jaw fatigue and improved comfort.
* **The Advent of the Bite Block:** In the mid-1950s, the first bite blocks were introduced, offering a more comfortable and secure fit in the mouth. These early bite blocks were often made of hard plastic, which could still cause discomfort and jaw fatigue.
