Hi.. Thanks for the query.. Well, it looks like there is deep infection in your tooth leading to inflammation of the nerves present in the centre of the tooth and it is leading to pain.. Other cause can be Cracked Tooth Syndrome.. There can also be pus formation below the root tips of the tooth leading to tooth abscess formation.. Applying Hurricane gel can give out temporary relief therefore you should take higher painkillers like Tramadol or Ketorolac for relief.. If still there is not much of relief you can consult an emergency room and get painkiller injection.. I would also suggest you to consult an Oral Physician and get evaluated and a clinical examination and investigation like x ray can help in diagnosis and treatment can be done accordingly.. If tooth is in condition to be saved then Root Canal Treatment can help.. If there is gross decay extraction is advisable.. Either of the treatment will be followed by a course of antibiotics like Augmentin and painkillers for relief.. Hope this helps.. Regards..
