Is it normal for a child’s gums to look bruised when their teeth are coming in?
It is not uncommon for the gums to appear bruised and swollen just prior to the tooth breaking through the gums. This bubble-shaped lesion is called an eruption cyst, and it usually requires no treatment. Often, the eruption cyst will last anywhere from a few weeks to a month. If it does not resolve in over a month, a dentist should evaluate it. Sometimes the lesion needs to be lanced, or cut open slightly, in order for the tooth to be able to erupt properly.
