Baby’s Dentist in Los Angeles Eruption cysts: What are they?

Q: My baby has a painful, dark bump on his gums. What is it?

A: It’s most likely an eruption cyst, also known as an eruption hematoma. An eruption cyst is a swelling over a primary or permanent tooth that is coming out. It contains fluid that collected around the erupting tooth, and it may be pale, blue or purple-colored due to some blood in the fluid.

Parents are often most concerned about the dark cysts, but eruption cysts usually aren’t anything to worry about. Once the tooth erupts the cyst will go away, so typically there’s no need for treatment. If the cyst remains for more than two weeks or the child is in a lot of pain, you should definitely see your dentist.
