Cecilia Wedenberg has written: 'Development and morphology of internal resorption in teeth'
It is very rare for people to be born with teeth, though it does happen. People are generally born with tooth buds that later develop into 20 primary teeth. As people loose these teeth, they are replaced with up to 32 permanent teeth, depending with how many of the four wisdom teeth they get.
Wisdom teeth are the last of the adult teeth to come through the gum, usually between the ages of 18-25. Some people never develop any wisdom teeth whilst others develop one wisdom tooth in each of their four dental arches.
one has external teeth the other has internal teeth
Regular braces have been known to cause what is called "root resorption". This essentially means that the roots of your teeth are eaten away at. While this is not always the case with regular braces, it does occur. That's what makes Invisalign a better choice. The force applied to your teeth to straighten them, is far smaller than that of regular braces, making the likelihood of root resorption next to nothing.
because they don't develop when you are a kid. they form as you are growing and they are most likely finished developing at the ages 20-24. some people develop their teeth bones early, some late. hope this helped.
We have four, two on the top and two on the bottom. i was a really weird case but i had 3 on the top and 4 on the bottom, so 7 in total i got mine out last week, all of them, and it has been a total nightmare. Normally there are four. But there are exeptions, some people have wisdom teeth missing. Other people have surnumerary teeth, meaning extra wisdom teeth.
Wolf pups are not born with teeth. But they will develop deciduous teeth or (baby teeth) after three or four weeks. They have about 28 baby teeth. They will loose their baby teeth between 14 and 30 weeks.
A tooth has many surfaces and some people describe the decay by where it is on the tooth. The cavities the dentist can see by a clinical exam are on the chewing surfaces of the teeth and on the gumline area. There are some tooth decay cavities that are formed between the teeth due to lack of flossing. For these cavities, the dentist must take an x-ray to find them. You cannot see them by looking or feeling with the "pick". Another type of tooth decay is something that happens to an injured tooth called "internal resorption". The dentist also needs to take an x-ray to find this, unless the decay eats it way out of the tooth and shows at the gumline.

None, though you are born with the "buds" for all of them. Around week 6 of gestation you develop the buds for baby teeth, and around the 20th week, you develop the buds for permanent teeth. If the teeth buds do not form at these times, chances are, a person won't have any teeth.
