A supernumerary tooth is an extra tooth. Typically, humans have sets of 20 baby teeth and 32 permanent teeth (assuming all four wisdom teeth develop), as shown in the diagrams below. If a person has one or more teeth that are additional to these typical sets of teeth, the person is said to have hyperdontia, and the additional teeth are known as supernumerary teeth.#Dentistry #Tooth #teeth
