Gingivitis Gang

The Gingivitis Gang - A group of monsters, a bird, and a bug who are the secondary antagonists of the series. Much exactly evil like the Cavity Goon, and mean and plain bad. They spend most of their time looking for trouble and harassing Timmy and his friends. Despite antagonizing Timmy and his friends, the Gingivitis Gang would never side with the Cavity Goon and sometimes have to side with Timmy to stop the Cavity Goon (as seen in some episodes).
