<human>: 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?
<bot>: 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.
