Wearing mouth guards for snoring is a method that is helpful for many people, but it does have some negative aspects as well. On the pro side, the devices typically help people to stop snoring, or at least to snore much less. On the con side, they can cause some physical discomforts, including mouth or jaw pain, excessive salivation, or dry mouth. They can also be expensive if one chooses a custom-fitted mouthpiece, as is recommended by most doctors and dentists; cheaper, non-prescription devices are also available, but they may not fit or work as well.
The most important benefit of using mouth guards for snoring is that in a great number of cases, they do correct the problem. Snoring is typically caused by the soft tissues in the throat falling inward during sleep, blocking a person's airway. A mouth guard usually draws the lower jaw forward into a position to avoid this and may also keep the tongue in place so it does not fall into a position that blocks breathing during sleep, allowing the person to breathe correctly at night. This, in turn, allows users to have a more peaceful, higher-quality night's sleep, leading them to feel more rested and energetic in the morning.
Some people may find that wearing mouth guards for snoring can lead to unpleasant side effects, though they are usually rather mild. Excessive salivation is one common complaint from people who use them. Other people may find that wearing the device leads to dry mouth. Jaw pain is also common, as most mouth guards pull the jaws forward slightly, and wearers may also notice pain in their teeth or gums, particularly if the device is made from poor-quality materials or not fitted properly.
Another potential issue with the use of mouth guards for snoring is the cost. Most medical professionals recommend that snorers be evaluated and fitted for a custom mouth guard for snoring that is designed to address their specific needs. While this is typically the most effective option, it can also mean spending hundreds of dollars. There are less expensive, generic versions available, typically made of plastic that can be softened in hot water and then bitten to mold to a person's mouth, and if they work, they can be a viable option for some. The materials used may not be of the same quality as prescription devices, however, and without the custom fit, may tend to be less effective in stopping snoring.
