This is an interesting question.There is a belief that the milk teeth do not have roots but they do. These roots 'dissolve' when the permanent teeth push through. I must say that I have not heard of a child of 5 years having root canal treatment. This does sound a bit drastic especially as his permanent molar tooth has already started pushing upwards under his milk molar tooth although this tooth is still going to take at least two years or longer before it comes through.It would be best to get a second opinion as soon as possible.
