How unhygienic are sports gum shields?

Sports mouthguards, also known as gum shields, can become unhygienic if they are not cleaned properly. The accumulation of bacteria, saliva, and food particles can lead to the growth of harmful microorganisms, such as mold and bacteria, which can cause bad odors, infections, and other health problems.

A study published in the Journal of Clinical Dentistry found that sports mouthguards can harbor high levels of bacteria, including Streptococcus mutans (a type of bacteria that can cause tooth decay) and Candida albicans (a type of yeast that can cause thrush and other infections). The study also found that sports mouthguards can be contaminated with mold and other microorganisms, especially if they are not cleaned properly.

It's important to note that you should clean your mouthguard after each use, and avoid using abrasive cleaning products or hot water, as these can damage the mouthguard. Also, make sure to store the mouthguard in a clean and dry place, and avoid storing in a closed bag or container.

In addition to cleaning, it's also important to inspect your mouthguard for signs of wear or damage before each use, and replace it if it's showing signs of wear or damage. A worn or damaged mouthguard may not provide the same level of protection as a new one.
