Is gingiva (gum) an organ?

Your gums are also known as your gingiva.

If they erupt you can have things such as inflammation or tearing of the gum.

Furthermore, an infection can occurs if it happens for an extended period of time.

This commonly occurs in people within the age group of about 17 to 25 years old. That's why we take out our wisdom teeth.

By the time you gain a little bit of wisdom, you start having all four of your third molars erupt right through your gingiva. You want to get them removed before you can have some type of bad reaction like inflammation or infection that can occur that can mess up the neighboring teeth that have erupted or grew out so well.
