**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.
The evolution of the scuba mouthpiece parallels the development of scuba diving itself. The early days of diving were marked by rudimentary equipment, with simple plastic tubes serving as the primary means of air delivery. But as technology advanced and diving became more sophisticated, so too did the design of the mouthpiece.
**The Bite Block:** This is the part that goes in your mouth, the point of contact between diver and equipment. It's typically made of high-quality silicone or rubber, chosen for its durability, flexibility, and comfort. The bite block is designed to be ergonomically shaped, allowing for a natural bite position that distributes pressure evenly and minimizes fatigue. It also incorporates a small lip or ridge, known as the **lip seal**, which helps create a tight seal around the diver's lips, preventing air from leaking out.
* **Customizable Designs:** The 1980s saw the emergence of customizable mouthpieces, allowing divers to choose the bite block size, lip seal shape, and even material that best suited their individual needs.
**6. ** **Cave Diving Mouthpieces:** Cave diving mouthpieces are often designed with a special feature called a ""saliva trap,"" which helps to prevent saliva from entering the regulator. This is important in cave diving because the regulator can become easily contaminated with saliva, which can lead to malfunctions.
