Snorkel Mouthpiece Guide: Types, Fitting & Replacement

Snorkeling is a fun water activity that lets you glimpse the beauty of underwater worlds. But all that enjoyment hinges on having a well-fitted, comfortable snorkel mouthpiece that allows you to breathe freely through the snorkel tube while swimming along the surface with your face in the water.

Choosing the right style and fit is crucial for a frustration-free snorkeling experience. This guide will cover the different types of snorkel mouthpieces, how to get the ideal fit, how to use them properly, replacement options, and care tips.

What is a Snorkel Mouthpiece?

A snorkel mouthpiece is the portion of the snorkel that you put in your mouth to breathe freely via the tube while floating face-down on the surface of the water.

The mouthpiece is typically made of soft, flexible and comfortable materials like silicone or rubber, designed to fit comfortably in your mouth creating a tight seal that keeps water out of your mouth.

It has a bite grip/tab/lug to keep it securely in place while allowing you to breathe through the snorkel tube without having to remove it from your mouth. The bite tabs also help in reducing jaw fatigue.

Types/Designs of Snorkel Mouthpieces

There are many types and styles of snorkel mouthpieces including;

Non-detachable mouthpiece

This is a type of mouthpiece that is permanently fixed or integrated into the snorkel tube. In other words, it cannot be removed or replaced separately from the snorkel. This design is common in many traditional snorkels

Replaceable/Detachable Mouthpiece

Most modern designs of snorkels have a detachable mouthpiece that can be replaced when it becomes worn or damaged. This can extend the lifespan of your snorkel.

For a truly personalized fit, some individuals opt for custom-molded snorkel mouthpieces. These are typically made by a dentist or professional and are molded to the exact shape of your mouth for maximum comfort.

This is the most common type of snorkel mouthpiece. It’s typically made of soft, durable silicone and has a simple design with a bite grip.

Children’s Mouthpiece

Snorkel mouthpieces designed for children are typically smaller and may have bright colors or fun designs to make snorkeling more appealing to kids.

Orthodontic Mouthpiece

These mouthpieces are specially designed for individuals with braces or dental issues. They have a design that accommodates dental work, ensuring a comfortable and secure fit.

Ergonomic Mouthpiece

Some snorkel mouthpieces have ergonomic or contoured shapes that are designed to fit the natural shape of your mouth more comfortably. They may have features like extended bite tabs for added comfort.

Types of mouthpieces can also vary depending on the shape of the snorkel tube;

  • Type A is a flanged mouthpiece with twin lugs at the end of a length of flexible corrugated hose designed for a flex-hose snorkel.
  • Type B is a flanged mouthpiece with twin lugs at the end of a short neck designed for a J-shaped snorkel.
  • Type C is a flanged mouthpiece with twin lugs positioned at a right angle and designed for an L-shaped snorkel.
  • Type D is a flanged mouthpiece with twin lugs at the end of a flexible U-shaped elbow designed to be combined with a straight barrel to create a J-shaped snorkel.
  • Type E is a flanged mouthpiece with twin bite plates offset at an angle from a contoured snorkel.

How to Use and Fit a Snorkel Mouthpiece

Here is a step-by-step guide on fitting a snorkel mouthpiece well to prevent any gaps that might cause water to seep in while breathing underwater.

  1. Hold the mouthpiece and inspect it. Ensure it is clean and free of debris such as soil dirt or any damage.
  2. Place the mouthpiece in your mouth. The curved part should be facing outward. Your teeth should line up with the bite tabs on the mouthpiece.
  3. Gently bite down on the mouthpiece. It should create a comfortable seal around your lips, which will prevent water from entering.
  4. Test your breathing. Inhale and exhale through the mouthpiece. Make sure air flows freely via the snorkel tube without any obstructions.

Fitting Tips:

  • Size matters: Choose a mouthpiece that conforms to your mouth size. It should feel snug but not too tight or too loose.
  • Proper alignment: Align the mouthpiece with your teeth, ensuring it sits comfortably and doesn’t cause any discomfort or strain.
  • Jaw position: Relax your jaw while biting down on the mouthpiece. Avoid clenching or forcing your jaw into an uncomfortable position.
  • Trial and error: If the initial fit did not go quite well, try different mouthpiece sizes or shapes until you find the one that suits you best.

Common mistakes you should avoid:

  • Overbiting: Avoid biting down excessively on the mouthpiece, as it can lead to jaw fatigue and discomfort. A gentle bite is sufficient to create a seal.
  • Breathing through the nose: Some beginners make the mistake of breathing through their nose while using a snorkel mouthpiece. Remember to breathe only through your mouth, utilizing the snorkel tube for airflow.
  • Unnecessary tension: Keep your facial muscles relaxed while using the mouthpiece. Tension in your jaw or facial muscles can lead to discomfort and cause you to open your mouth; this way, water will seep in.
  • Ignoring discomfort: If the mouthpiece feels uncomfortable or causes pain after extended use, take a break and readjust it. Continuing to use an ill-fitting mouthpiece can cause soreness and jaw fatigue.

How to Replace a Snorkel Mouthpiece

Snorkel mouthpieces are not designed to last forever and may require replacements periodically. Over time, the mouthpiece loses its original function due to wear and tear, exposure to the elements, and regular use.

Signs indicating the need for replacement:

  • Visible wear and tear: Check for signs of deterioration, such as cracks, tears, or significant discoloration on the mouthpiece.
  • Hygiene concerns: Mouthpieces accumulate bacteria or develop an unpleasant odor over time. If cleaning no longer resolves these issues, replacing the mouthpiece is advisable.

There are a few options available for choosing when replacing your snorkel mouthpiece, including:

  • Buy a pre-made mouthpiece: These are ready-to-use mouthpieces that you can purchase online from retailers. They come in different sizes and materials to suit your preferences.
  • Custom-fit mouthpiece: These mouthpieces are made from moldable materials that can be shaped to fit your unique mouth contours.
  • Universal mouthpiece: Universal mouthpieces are designed to fit most snorkels and are a convenient option if you want a replacement that fits various snorkel models.

Here is how you can replace your snorkel mouthpiece:

  1. Remove the existing mouthpiece: If your snorkel has a detachable mouthpiece, gently pull or twist it to separate it from the snorkel tube. Some mouthpieces may require unscrewing or releasing a locking mechanism.
  2. Clean the snorkel: Clean the snorkel tube thoroughly before attaching the new mouthpiece. Rinse it with fresh water and ensure it’s free from debris or residues.
  3. Prepare the new mouthpiece: If you’re using a pre-made mouthpiece, it should be ready for use. If you’re using a custom-fit mouthpiece, follow the manufacturer’s instructions to mold it properly before attaching it to the snorkel.
  4. Attach the new mouthpiece: Align the new mouthpiece with the snorkel tube, ensuring it fits securely. If it’s a detachable mouthpiece, follow the instructions provided to lock it in place.
  5. Test the seal: Place the mouthpiece in your mouth and bite down gently to create a seal. Inhale and exhale through the mouthpiece to ensure there are no leaks or obstructions. Adjust the position if necessary.
