Hi Ive had a root canal done and it wasnt finished. I ended up getting infected and was having numbess on the left side of my face. I went back to the dentist and he opened a hole in the tooth to let the infection drain out. He then put me on penicillin but im still experiencing numbess on the face. Could it be infected still?
Thanks for your query, I have gone through your query. The numbness in the face can be because of the tooth infection resulting in a cyst formation causing pressure over the nerve. Nothing to be panic, consult an oral physician and get it evaluated. Meanwhile you can take a nerve regenerating Chat Doctor.  At the same time if any cysts are there, then it has to be treated surgically. I hope my answer will help you, take care.
