Frequently asked questions

Every AlienGuard is made from an impression of your own teeth. You order, we ship you an at-home impression kit, and we form your guard on a model of your bite. There is no size chart to guess from.

Origin is our combat guard for boxing, MMA, Muay Thai and kickboxing. Both are 5 mm, the industry standard for competitive combat sports. Origin Pro is more breathable and comfortable, with an optional High Impact 6mm upgrade for super high-impact training and fights. NanoBite is ultra-slim for wrestling, BJJ, football and team sports like hockey and basketball. PowerBite is built for lifting. See the model comparison.

Non-combat guards are 4 mm thick. Combat guards are 5 mm thick to absorb more force from direct, heavy hits.

Yes. Athletes with braces can get AlienGuards, but your dentist needs to take the impression instead of using our at-home kit, so your braces don't get damaged. Your dentist can take an impression or 3D scan, then ship it to us or email it to impressions@alienguards.com. If you have another dental appliance or loose teeth, talk to your dentist before taking an impression.

Custom mouthguards are thin and precise, so most athletes breathe and talk normally. NanoBite is our lowest-profile option if breathing and talking matter most.

Follow our step-by-step impression guide. It takes about 10 minutes, and the putty sets in 2 minutes 30 seconds.

Email a photo to support@alienguards.com and we will let you know if it can be used. You can also order a replacement impression kit or extra putty.

Your custom mouthguard is crafted within 10–14 business days after we receive a good impression, then shipped with tracking.

Rinse it in cool water before and after each use. Brush it gently with a soft toothbrush and mild soap, not toothpaste, which is abrasive and can scratch and dull the guard. For a deeper clean, soak it in an effervescent denture or retainer tablet in cool water as the label directs, then rinse. Air-dry it in a ventilated case, and keep it away from hot water, dishwashers, hot cars and direct sun so it keeps its shape. No mouthwash, alcohol or bleach.

We recommend replacing it every year, or sooner if it becomes damaged or worn.

Choose Impression Storage when you build, and we keep your model on file for future reorders.

Mouthguards help protect against chipped, cracked or knocked-out teeth during sports and activities with a high risk of falls or contact, such as football, basketball, hockey, gymnastics and martial arts.

A custom mouthguard is made from an impression of your teeth, so it is more comfortable and secure. It doesn't slip or fall out, and it is easier to wear for long sessions.

Yes, custom mouthguards usually cost more than over-the-counter options. The comfort, protection and durability make them a worthwhile investment.

Stock guards are pre-formed and offer basic protection. Boil-and-bite guards are softened in hot water and bitten into for a closer fit. Custom-fit guards, like AlienGuards, are made from an impression of your teeth for the most comfortable and secure fit.

A mouthguard can help reduce stress on the jaw joint, which may relieve TMJ pain linked to clenching or grinding. Ask your dentist about your situation.
