No, you are born with the crown portion of the teeth even though you can't see them yet. The root forms last. The first tooth comes in at about 6 months of age, which is the bottom central incisor.

This is a long article but it starts with a great x-ray showing tooth developement. There are 3 molars in the picture. The one on the right is fully formed and in the mouth. The middle one (called the second molar) is developing. It's almost erupted in mouth, and the root is partially formed. That's about mid-develpement for a tooth. As the root is forming, the crown erupts further into the mouth. That's part of what makes a tooth erupt is the devolping rooth, the other parts are too boring and technical to really go into.
The molar on the left (the one that looks like a weird donut) is the 3rd molar or wisdom tooth. It's just beginning to form. The crown has formed first (that's the center part). As time goes on the root will form and the tooth will look like it's neighbors to the right. The outside rim of the donut is the follicle. It's what contains all the stuff (cells) to form the new tooth.
When your born all your teeth look like this one on the x-ray. Some are even less pronounced. As time goes on they all start looking like regular teeth as they keep growing.
So to answer your question, no, you're not born with all the roots completely formed. They all start out looking like this and then start growing their roots from there.

You are born first with the tooth buds in which the cells will differentiate to form the crown of the tooth and then the roots will form and close at the apex (root tip) last. Babies have been born with teeth in uncommon instances but for the most part they are still forming underneath the gums at birth and then the first teeth will normally erupt between 6-12 months old (the lower central incisors). And baby teeth are much smaller roots than your permanent teeth. Good luck!

No as a matter of fact your baby teeth never form roots. It's your primary teeth or adult teeth that form as a crown first then develops roots as it pushes your baby teeth out of the way.

Everyone is born with what are called tooth buds and they will develop into the teeth. As the tooth bud grows and develops into a tooth the gum swells and opens and the tooth emerges which is why some babies are cranky when this happens. Not sure where the dental student goes to school but I'd steer clear where my mouth is concerned.

you are born with you deciduous teeth (baby teeth) almost fully formed in the jaw bones and the beginnings of your permanent adult dentition. by the time you are 13-14 all your teeth are fully formed, if you have third molars (wisdom teeth) the roots of these may still be forming at this time.

the roots are usually well formed and you can immediately crash a bone if at all you happen to realise. the only problem that is there is that you are very tiny and most of the time your brain has not developed to know that you should eat food.

You're born with all of your teeth already formed, they're just not above the gum line yet.

I know that you are born with your wisdom teeth in your head already - cos I never was born with any!
