Why Does My Mouthguard Keep Falling Out?

Wearing a mouthguard is essential for protecting your teeth and preventing injuries during physical activities. However, if your mouthguard keeps falling out, it can be frustrating and ineffective. There are several reasons why this might be happening, and understanding them can help you find a solution. In this article, we will explore the various factors that can cause your mouthguard to fall out.

1. Incorrect Fit

One of the most common reasons for a mouthguard falling out is an incorrect fit. If your mouthguard is too loose or too tight, it will not stay in place properly. A mouthguard should fit snugly over your teeth, providing a comfortable and secure fit. If it is too loose, it may slide around or even fall out during physical activity.

There are two types of mouthguards: stock mouthguards, which come pre-formed and are the least expensive option, and custom-fit mouthguards, which are made specifically for your mouth by a dentist. Custom-fit mouthguards offer the best fit and are less likely to fall out compared to stock mouthguards.

If your mouthguard is not fitting properly, it may be time to consider getting a new one. Consult with your dentist to ensure you get the right size and fit for your mouth.

2. Poor Material Quality

The quality of the material used to make your mouthguard can also affect its ability to stay in place. Cheap or low-quality mouthguards may not have the necessary grip or retention to stay securely in your mouth during physical activities. These mouthguards may be more prone to slipping or falling out.

Investing in a high-quality mouthguard made from durable materials can significantly improve its ability to stay in place. Look for mouthguards that are specifically designed for sports and have good reviews regarding their fit and retention.

3. Improper Mouthguard Care

Proper care and maintenance of your mouthguard are crucial for its longevity and effectiveness. If you are not cleaning and storing your mouthguard correctly, it may become warped or lose its shape, leading to a poor fit and increased likelihood of falling out.

After each use, rinse your mouthguard with cool water and brush it gently with a toothbrush and toothpaste. Avoid using hot water or abrasive cleaners that can damage the material. Store your mouthguard in a clean, ventilated case to prevent it from collecting bacteria or becoming misshapen.

4. Jaw Clenching or Teeth Grinding

If you have a habit of clenching your jaw or grinding your teeth, it can affect the stability of your mouthguard. Excessive jaw movement can dislodge the mouthguard, causing it to fall out during physical activity.

If you suspect that jaw clenching or teeth grinding is causing your mouthguard to fall out, consider discussing this with your dentist. They may recommend a custom-fit mouthguard specifically designed for teeth grinding or suggest strategies to manage the habit.

5. Age and Wear

Over time, mouthguards can wear out and lose their shape, making them more prone to falling out. If your mouthguard is old or showing signs of wear and tear, it may be time to replace it.

Regularly inspect your mouthguard for any signs of damage, such as cracks, tears, or a loose fit. If you notice any issues, it is best to replace your mouthguard to ensure optimal protection.

6. Breathing or Saliva Flow

Some individuals may experience mouthguard slippage due to excessive saliva flow or difficulty breathing while wearing the mouthguard. This can cause the mouthguard to become dislodged or uncomfortable, leading to it falling out.

If you find that your mouthguard is consistently falling out due to saliva flow or breathing issues, consult with your dentist. They may be able to recommend a different type of mouthguard or provide solutions to improve your comfort and reduce slippage.


When your mouthguard keeps falling out, it is important to identify the underlying cause and address it promptly. Whether it is an incorrect fit, poor material quality, improper care, jaw clenching, age and wear, or breathing and saliva flow issues, understanding the reasons can help you find a suitable solution.

Remember, a well-fitting and properly maintained mouthguard is crucial for protecting your teeth and preventing injuries during physical activities. Consult with your dentist for personalized advice and recommendations to ensure you have a mouthguard that stays securely in place.
