Do you enjoy snorkeling but experience a sore jaw when you are done? This can be caused by a number of reasons but it usually relates to the mouthpiece of your snorkel. Many snorkels of lesser quality use mouthpieces that are made of a hard plastic or PVC material. This puts the jaw in an uncomfortable position and is a major cause of jaw fatigue. Those with smaller bite radii may want to consider a smaller size mouthpiece made of silicone which is 100 percent more comfortable than the hard plastics. If you already own a snorkel and you know that the mouthpiece is replaceable, then definitely consider this mini silicone mouthpiece. It is specifically designed for those with smaller bites and is made of 100 percent hypoallergenic silicone. You will be glad you did.
