Why Does My Mouthguard Smell?

Many people who use mouthguards for sports or teeth grinding may notice an unpleasant smell coming from their mouthguard. This can be a frustrating and embarrassing problem, but there are several reasons why mouthguards can develop an odor. In this article, we will explore some of the common causes of mouthguard odor and what you can do to prevent it.

Poor Oral Hygiene

One of the most common causes of mouthguard odor is poor oral hygiene. If you are not brushing and flossing your teeth regularly, bacteria can build up in your mouth and transfer to your mouthguard. This can cause an unpleasant smell to develop over time. To prevent this, make sure you are brushing and flossing your teeth at least twice a day and cleaning your mouthguard regularly.

You can clean your mouthguard by rinsing it with water after each use and brushing it with a soft toothbrush and toothpaste at least once a week. You can also soak your mouthguard in a solution of water and vinegar or mouthwash to help kill bacteria and eliminate odors.

Wearing the Mouthguard for Too Long

If you wear your mouthguard for extended periods of time, it can become a breeding ground for bacteria and develop an unpleasant odor. This is especially true if you are wearing your mouthguard while eating or drinking, as food particles can get trapped in the mouthguard and cause bacteria to grow. To prevent this, make sure you are only wearing your mouthguard when necessary and remove it when eating or drinking.

You should also replace your mouthguard every six months to a year, depending on how often you use it. Over time, mouthguards can become worn and lose their shape, making them less effective and more likely to develop an odor.

Storing the Mouthguard Improperly

If you are not storing your mouthguard properly, it can develop an unpleasant odor. Mouthguards should be stored in a clean, dry place when not in use. If you leave your mouthguard in a damp or dirty environment, bacteria can grow and cause an odor to develop.

You should also avoid storing your mouthguard in direct sunlight or high temperatures, as this can cause it to warp or lose its shape. Instead, store your mouthguard in a case or container that allows for proper ventilation and air circulation.

Using the Wrong Cleaning Products

If you are using the wrong cleaning products on your mouthguard, it can cause an unpleasant odor to develop. Some cleaning products, such as bleach or alcohol, can damage the material of your mouthguard and cause it to break down over time. This can lead to an odor and make your mouthguard less effective.

Instead, use a mild soap or toothpaste to clean your mouthguard, or try a specialized mouthguard cleaner that is designed to kill bacteria and eliminate odors.

Medical Conditions

In some cases, mouthguard odor can be a sign of an underlying medical condition. Certain medical conditions, such as dry mouth or gum disease, can cause an unpleasant odor to develop in the mouth. If you are experiencing persistent mouthguard odor despite proper oral hygiene and cleaning, you should consult with your dentist to rule out any underlying medical conditions.


Mouthguard odor can be a frustrating problem, but there are several steps you can take to prevent it. By maintaining good oral hygiene, wearing your mouthguard for the appropriate amount of time, storing it properly, using the right cleaning products, and addressing any underlying medical conditions, you can keep your mouthguard clean and odor-free.
