Lost feeling in tongu after root canal

I was with a dentist on Friday and he had to redo a crown which was done previously. Since the previous dentist did a root canal twice and I still had feeling in the tooth, this dentist redid the root canal a third time.

When he injected the needle to administer the local anesthetic, I felt tha usual needles and pins and directly aftera very sore and sharp stabbing pain, almost like being shocked by electricity and immediately the left side of my tongue went numb. The feeling in my mouth and cheeks return, but now, even after 6 days, I still have no feeling on the left side of my tongue. When I asked him about it, he said it is a side-effect of the anesthetic. I am worried that he damaged a nerve.

Could you please let me know what your thoughts are and if I can expect to recover the feeling in my tongue.

It is possible that the nerve is damaged. However in most cases such as these, the feeling will return. This may take a few weeks.
IF there is still no improvement after a month, see your dentist.
