Why do your gums swell when you use a night guard?

Gum swelling when using a night guard can be caused by several reasons:

- Poorly fitted night guard: If your night guard is too tight, it can press against your gums and cause them to become irritated and inflamed.

- Allergic reaction: Some people may be allergic to the material of the night guard, such as acrylic or latex. This can also cause gum swelling.

- Gum inflammation (gingivitis): Gingivitis is an inflammation of the gums that can be exacerbated by the use of a night guard if it is not cleaned properly. Bacteria and food particles can accumulate on the night guard and cause the gums to become inflamed and swollen.

- Bruxism: Bruxism, or teeth grinding, can put additional pressure on the gums and cause them to swell. A night guard can help reduce bruxism but may not completely eliminate it.

- Excessive saliva production: Some people experience increased saliva production when using a night guard. This can lead to gum irritation and swelling.

If you experience gum swelling when using a night guard, it's important to consult with your dentist. They can determine the cause of the swelling and recommend the appropriate treatment. In some cases, it may be necessary to adjust the night guard or use a different material to alleviate the gum swelling.
