Custom vs. Boil-and-Bite Mouthguards: What's the Difference?

Protecting your teeth doesn't have to be complicated — but choosing the right mouthguard can feel that way. Whether you're at the gym, on the field, or just skating in the park, the right guard makes your experience safer and more comfortable. In this blog, we'll break down custom vs. boil-and-bite options, cover their pros and cons, clear up common myths, and show how ClearClub can help you find your perfect fit.

Do You Really Need a Custom Mouth Guard?

Sports injuries happen — about 8.6 million a year in the U.S., to be exact. And yes, your teeth and jaw are not off the hook: orofacial injuries are more common than you might think. Studies show that dental injuries are among the most common sports-related mishaps, with broken or knocked out teeth topping the list. That's why experts recommend wearing a mouthguard — it protects your teeth from collisions and helps you play with confidence.

Custom mouthguards are molded to fit your teeth perfectly, giving you a snug, comfortable fit. That means better protection during high-impact activities, whether it's contact sports like football or soccer, or non-contact ones like skateboarding and mountain biking. The American Dental Association notes that a properly fitted mouthguard can reduce both the likelihood and the severity of dental injuries while you're in the game.

Custom vs. Boil-and-Bite: Head-to-Head Comparison

When it comes to choosing a mouthguard, understanding the differences between custom and boil-and-bite can help you make the right choice.

What is a Custom Mouth Guard?

The Cleveland Clinic explains that a custom mouthguard is made to fit your teeth precisely, providing better and more comfortable protection during sports. The process involves capturing an impression of your teeth, which is then used to create the guard. Custom-made options come in two types: dentist-made and direct-to-consumer. Some direct-to-consumer brands provide at-home impression kits, making the process more accessible to athletes and recreational players alike.

What is a Boil-and-Bite Mouth Guard?

A boil-and-bite mouthguard is an easy alternative to a custom one. You soften it in hot water and then bite down so it molds to your teeth. They're affordable and easy to grab at most pharmacies or sports stores, and they fit better than a basic stock guard. They can feel a bit bulky, though, so they're usually best if you're just trying a mouthguard for the first time or don't need it every day.

What is the Difference Between Custom and Boil-and-Bite Guards?

To make things easier, here are the key factors to consider when choosing your mouthguard.

Common Misconceptions About Sports Guards

Don't let misinformation guide your choice. Here are the five most common myths about athletic mouthguards — and the truth behind them.

1. All sports mouthguards are basically the same. False. There are four main kinds: stock, boil-and-bite, and direct-to-customer. They differ in comfort, fit, and protection, so the right choice depends on your needs and activity.
2. Boil-and-bite mouthguards fit just as well. Incorrect. Boil-and-bite guards aren't precisely molded to your teeth — biting alone can't fully capture your teeth's shape.
3. Custom mouthguards are only for professional sports players. That's a myth. Custom mouthguards aren't only for pros — anyone who wants solid protection, whether for practice, games, or just playing for fun, can benefit from a custom fit.
4. Boil-and-bite mouthguards are better than custom ones because they're cheaper. They do cost less upfront, and that's appealing. But that lower price often means they won't last long, may not feel as comfortable, and won't protect against hard hits as well as a custom-made guard.
5. All custom mouthguards are expensive. False. While dentist-made guards can be costly, some direct-to-consumer options are more affordable while still offering a precise, custom fit.
