Teeth problem. To break in same way.

Case is like I have teeth problem since childhood.  crown part of milk teeth broke into small pieces and root part used to remain inside only and was removed from dentist My each any every tooth was removed then  only if there was growth of new teeth. Two yrs back incisor tooth of lower jaw was replaced with a cap due to cavitiy. A month before I had opg and dentist told that almost all of the teeth are damaged. Root canal and capping of 4 teeth of upper jaw(incisor and canine) is completed two days ago and pain is reduced now. But the cap of the lower jaw  is broken with tooth inside it and in the same way as that of milk tooth, only root is remaining inside and according to the docs suggestion now I just put cap coz all other teeth are also going to break in same way.
