From The Manufacturer

The most unique feature of the SISU Aero is its super-slim, ultralight design. At a lean 1.6 mm, the Aero is 50% thinner than a standard mouthguard. Combined with its quick, custom and remoldable fit, it's easy to forget there's something awesome and plastic inside the mouth. Sisu Aero is available in 3 sizes; Small, Medium, and Large. SISU guards are made from a material that absorbs and diffuses impact throughout the entire mouthguard, meaning that much less impact force is transferred to the teeth. Using one-of-a-kind Diffusix Technology, the impact force is distributed over larger areas, which means less risk of dental injury during competition. Conventional mouthguards are made from a material that's too soft to fully protect teeth from harm.

What experts didn't like

Probably won't fit younger children (recommended for 11 and up). On the pricey side. Some users said they had a difficult getting to mold properly to their mouth
- Heavy
Not recommended for extremely high impact sports. Material can get bitten into to cause holes to form. Slightly pricier than other boil and bite mouth guard. Material can fold onto itself during the molding process if you aren't careful!

An Overview On Lacrosse Mouthguards

Mouthguards are responsible for so much more than just preventing injury to your teeth. They actually help protect your jaw and soft tissues and may even decrease your chances of suffering a concussion. If you play a contact sport, like lacrosse, you’ll need to purchase a mouthguard before you set foot on the field.

Lacrosse players who currently wear orthodontics will need a special mouthguard that fits over their braces. The Shock Doctor Double Braces Lacrosse Mouthguard is an excellent choice. It’s made from a medical-grade silicone using an ergonomic design that fits directly over the braces without requiring any special molding. The silicone is also comfortable against teeth and gums and free of BPA and latex.

Athletes who don’t wear braces will have a wider selection available to them. For example, the SISU Aero Lacrosse Mouthguard comes in three different sizes and 16 different colors. Small is the best choice for individuals under 5 feet in height, while medium is for players who fall between 5 and 6 feet. Anyone taller than 6 feet would need to order a large.

Lacrosse players who don’t want to risk losing their mouthguards in the middle of a game may want to consider a model that has an attached strap, like the Oral Mart Strapped LAX Mouthguard With Vented Case. This strap wraps around the bar of your headgear, so that if the mouthguard got knocked loose, it would simply hang from the bar.

Consider going with a lacrosse mouthguard that has a little something extra to offer. The Redline Sportswear Custom Molded Lacrosse Mouthguard comes with a ventilated storage case that has an attached carabiner. This feature allows you to quickly clip the case to a backpack or equipment bag.

The Lacrosse Mouthguard Buying Guide

  • It’s important that you take care to follow the lacrosse mouthguard’s molding instructions exactly, as the material can fold over onto itself during the molding process. Typically, the molding process involves placing the lacrosse mouthgaurd in boiling water for a designed period of time and then moving it to a bowl of cold water for a few seconds. Next, the player needs to align and bite down on the mouthguard while sucking out excess water and air. After waiting the recommended amount of time, the mouthguard can be removed.
  • If you don’t get a perfect fit the first time you attempt to mold your mouthguard, you can repeat the process and try again.
  • Thinner mouthguards aren’t always ideal, as one can bite through them during a crash.
  • Not all mouthguards are created for athletes with braces, so check the product packaging for compatibility if you wear orthodontics.
  • Every time you use your lacrosse mouthguard, you’ll need to clean it. After rinsing the mouthguard with a little cold water, brush it gently using a mild soap and a toothbrush. Once you have the mouthguard clean, you need to rinse it again and place it in a ventilated mouthguard container for safe storage.
  • Heat damages molded mouthguards, so you’ll need to store the mouthguard in a cool dry location. Keep it out of the path of direct sunlight and never clean it with hot water.
  • The price for a lacrosse mouthguard varies slightly based on design, size and the intended user. Both the Redline Sportswear Custom Molded Lacrosse Mouthguard and the Oral Mart Strapped LAX Mouthguard With Vented Case are extremely affordable options. Players will pay a moderate price for the Shock Doctor Double Braces Lacrosse Mouthguard. The SISU Aero Lacrosse Mouthguard is able to command the highest price, as it offers a custom fit and over 16 color choices.
