4 Signs It Is Time To Replace Your Sports Mouth Guard

Jan 15, 2025

If you are an athlete or love participating in sports activities, you know how important it is to have the right protective care. To prevent the risk of dental injuries during sports, many dentists recommend getting a custom sports or athletic mouth guard. But how long does it last, and when should you consider replacing it with a new one? We’ll answer these questions below.

What Are The Benefits of Having A Sports Mouth Guard?

Sports injuries are one of the most common causes of tooth damage. In many cases, the damage is irreversible, such as if a tooth fractures or gets knocked out. This is why dental professionals suggest getting a sports mouth guard to prevent the risk of dental injuries.

A sports or athletic mouth guard is a special oral appliance that is designed to protect your teeth and oral tissues against injuries. It acts as a cushioning layer that absorbs high-impact forces during sports activities, preventing direct damage to your teeth and gums.

In addition to protecting your teeth, a mouth guard lowers the impact of injuries to your jaws and temporomandibular joints (TMJ). It also protects your dental work, such as braces, veneers, fillings, or crowns.

How Long Do Mouth Guards Last?

Custom-designed sports mouth guards are made of durable materials that can last a long time. If you maintain your mouth guard properly, it can last as long as 3 to 5 years. However, you may need to replace your sports mouth guard regularly to ensure that it fits your teeth perfectly.

Generally, it is recommended that children and teens get new mouth guards every 12 to 18 months. If you are an adult who already has fully developed teeth and jawbones, you may use the same mouth guard for a longer time.

When Should You Consider Replacing Your Sports Mouth Guard?

Here are some signs to know when it is the right time to replace your old mouth guard with a new one:

  • Loose fit: Over time, your mouth guard may become loose in your mouth. If it does not fit snugly or falls out easily, it is best to consider getting a new one.
  • Broken or damaged surface: Sports and high-impact activities can damage your mouth guard. If you notice a broken edge or too many cracks on the surface, it is time to discard it.
  • Bite changes: Your bite also changes as you grow. This is more noticeable in children and teenagers as their teeth and jaws are still developing. So, call your dentist if your old mouth guard feels too tight or loose.
  • Soft tissue damage: The whole point of a mouth guard is to protect your teeth and oral tissues. If you experience sores or soft tissue damage when wearing a mouth guard, it is definitely time for replacement.
