The little round ridges on new front teeth are called mamelons. These ridges make it easier for the teeth to break through the gums and come into the mouth. They typically wear down within a couple of years with normal chewing and biting.

Ridges on the biting edges of adult front teeth are called mamelons. They help the teeth erupt into the mouth, and they usually wear away within a few years.

How do you grow new tooth in age 17?

You can not grow a new tooth. All your teeth are present at birth. Your first teeth come in while you are a baby but your second teeth are all ready there as small 'buds" ready to form and come in as you loose the first teeth. As you know, your last teeth do not come in until you are 17-20. Because they come in last and you are older, they are called wisdom teeth.
