Water splashing when dentist drilled my teeth?!
Question: is there water in the teeth?
also it kind of hurt when he drilled even though he injected anesthetics, why does it hurt when teeth dont have nerves in it? isnt it just bone?

1) The high speed drill sprays water to keep the drill bit cool, to debride the area the dentist is drilling, and to keep the tooth cool as the dentist is drilling. Friction and heat it creates can kill the nerve, therefore there must be water spraying constantly as your tooth is drilled.
2) If the tooth hurts when it is being drilled, the freezing was not effective. Either you needed more freezing or more time for the freezing to take effect. Another reason for freezing to not be effective is if the tooth is infected (abscessed).
3) Teeth DO contain nerves. In the middle of every tooth there is a chamber called the pulp chamber. It contains small capillaries that carry blood (therefore nutrients) in and out of the tooth. It contains nerves so that you can feel stimulus like hot, cold, pressure, etc. Without nerves, you would not know if you were doing something that could traumatize the tooth. Finally, the pulp chamber contains a lymphatic system. So, there is a lot going on in such a small space!
The crown of the tooth (the part you see when you look in the mirror) has enamel on the outside followed by a layer of dentin. Under the dentin is the pulp.
The drill, or handpiece, sprays water to keep the tooth cool since the rpms are so high... the water is not coming from the tooth.
If the area is numb, you shouldn't feel anything. Maybe the dentist didn't wait long enough or the decay was close to the nerve, causing you some sensation...
All teeth have nerves in them unless they've had root canal treatment... then the nerve (pulp) is removed, so the tooth is 'dead'.
Bone surrounds the teeth and keeps them in place.
