Hi.. Can understand your concern.. As per your complain if you have infection in your root canal treated and crown placed wisdom tooth and you take so much of pain to keep your infection at the bay, the best and the most appropriate treatment is to get it extracted. As a wisdom tooth serves no purpose in chewing and is just not considerable to keep an infected wisdom tooth.. As you had BELL S PALSY in the past, it is true that it happened to you as a result of the anaesthesia injection given to you for dental treatment and it has traumatized your nerve (Facial nerve) leading to paraesthesia of one side of the face.. But you should not be worried as this condition will happen again is not necessary.. I would suggest you to go to an ORAL AND MAXILLOFACIAL SURGEON and describe him the entire sequence and i am very sure he will suggest you the more accurate way of proceeding with your treatment and he will definitely extract your tooth with ease. The other part of your concern is to take antibiotics or not.. Ideally an antibiotic cover is given to every patient having infected tooth that is indicated to get extracted BUT you should take the antibiotics as described by the dentist and not yourself and taking antibiotics and painkillers specially after extraction is mandatory and you should take the medicines irrespective of any natural way you are using to heal up your infection for better results of your treatment. Hope your query gets solved.. All the best.. Regards.. Dr.Honey Nandwani Arora.
