It could hurt if you pulled it out hard. But if you wiggle it everyday, it would not hurt then.
they probably won't pull out all 12 teeth.
no
Yes, baby teeth can hurt, and most of the time will hurt. The reason they hurt is because you are exposing tender gums and you are ripping roots out of the gums.
If everything is just right, there is no need, but sometimes it is done. They usually only pull them if they are baby teeth, to make room for things to move around. Baby teeth don't hurt as bad to have removed. It will just be tender for the first day or two.
Only your baby teeth will be replaced with other teeth when they are pulled or fall out. A human has 20 baby teeth total. If you pull out human adult teeth they will not come back.
The injections sting, its not that bad though. Then when they pull your teeth out its fine.
A reputable dentist would not pull baby teeth without a reason he could back up with X-rays and published research. The most common area of a dentist pulling baby teeth is the upper incisors and canines. He would be concerned, if there was evidence via X-rays, that the permanent teeth were becoming impacted or twisting because of the late eruption of the permanent teeth, and may make the decision to help nature along.
Baby teeth have no nerves or "feet" like permanent teeth, so when they come out, it's just the tooth.
I believe this is because your adult teeth are there all the time and just move up to replace your baby teeth. It is not that adult teeth suddenly start growing when your baby teeth fall out. If an adult tooth is lost, there is nothing there to replace it.
There's no exact date. They just come loose and you pull them out.
Pulling baby teeth out does not usually cause a person any pain. Baby teeth have a very small root or no root and are usually painless to remove. If your baby teeth are causing you pain when you pull them out, you should probably check with a dentist to be sure that the teeth and gums are healthy.
If the dentist says that they have to pull out your baby teeth, then there must be something very wrong with the teeth. Either they have holes, or they are rotting and could spread an infection...then they would have to pull them out. If your teeth have none of these problems, then you should be able to pull them out yourself when they are ready.
