Hello,
Thanks for the query. With your symptoms, it is clear that infection has spread from wisdom teeth.Deep
dental caries which has spread to third layer of the teeth called pulp should be treated with the
root canal procedure(RCT) in time. If it is not treated, it will spread to adjacent bone causing
abscess which will lead to severe pain, swelling, difficulty in mouth opening and discharge of pus. This is followed by
lymph nodes swelling of neck which is your symptom now. Further if not treated will lead to space infection.
Due to more infection, low dose or lower spectrum antibiotics does not act. I will suggest you to consult your
dentist for clinical examination and higher spectrum antibiotics through IV (Intra-venous) or IM(Intra-muscular) route that can effectively reduce infection faster acting against resistant bacteria's. Along with it, there is need to drain the abscess by access opening in the infected teeth.
Once the infection is completely subsided, treatment can be planned out for restoring the teeth.
Hope I have answered your query. If you need further clarification, feel free to ask. Thank you.
