We just learned about the Supernumerary Teeth.
Another thing that can happen in the mouth is Hypodontia, which means teeth that are missing, that never grew in the mouth.
This means when a person grows up and for some reason some of their teeth never came in.
They could be missing molars or incisors or canines.
If a lot of teeth are missing, it is called oligodontia.
If someone is missing all of their teeth, it is called anodontia.
