Moreover, significant amounts of people who fear the dentist avoid visiting until they really need to. But there is good news on the horizon as well—recent research also suggests that we might soon be able to refill the holes in our teeth with healthy, living tissue, giving our permanent teeth a second chance. Compared to other species, you may think we humans are extraordinarily unlucky to have to depend on the same set of adult teeth for the majority of our life. Shark enthusiasts are familiar with the fact that sharks have unlimited sets of teeth during their lifetimes.
Is a Third Set of Adult Teeth Possible? | Ottawa Dentist - Dr Pamela Li
Hyperdontia is a condition that causes too many teeth to grow in your mouth. These extra teeth are sometimes called supernumerary teeth. They can grow anywhere in the curved areas where teeth attach to your jaw. This area is known as the dental arches. The 32 adult teeth that replace them are called permanent teeth. You can have extra primary or permanent teeth with hyperdontia, but extra primary teeth are more common. The main symptom of hyperdontia is the growth of extra teeth directly behind or close to your usual primary or permanent teeth.
The following chart shows when primary teeth also called baby teeth or deciduous teeth erupt and shed. As seen from the chart, the first teeth begin to break through the gums at about 6 months of age. Usually, the first two teeth to erupt are the two bottom central incisors the two bottom front teeth.

The vast majority of mammals grow two sets of teeth during their lives. Our young are born toothless because mammals produce milk for their young, and mothers definitely don't want to be nursing babies with rows of sharp teeth.
