[|Human|] Hi,Four years ago, I had a root canal done on my 2nd upper molar on the left side of my mouth. For the past 2 years I have been having severe pains from the tooth and surrounding areas, it has become impossible to chew with that side of my mouth due to the pain. Also, there is a very bad smell coming from between the tooth and the surrounding teeth. I also have problems with my sinuses and it makes my breath smell bad.Ive been to the dentist several times but not of the treatments seem to work. Please what could be the problem and can an extraction help?Thanks.
[|AI|]  Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint it seems that there is re-infection in the tooth or lingering infection since the treatment was done. The other thing is that pain in teeth surrounding the area can be radiating pain from the infected tooth or can also be due to sinus infection. Sinus infection can also occur secondary to the tooth infection of upper teeth as the roots of upper back teeth lies in proximity with the sinus floor and at times lies into the sinus. I would suggest you to consult an Endodontist and get evaluated as well as consult an ENT specialist, and he can advise you PNS View or MRI of sinuses to rule out the exact cause of problem and treat accordingly. As of now you can take painkillers like Ibuprofen or Tramadol for pain. In case if tooth is found infected, re-root canal or extraction can help. Infection in the sinuses can be treated with antibiotics, anti-inflammatory painkiller, steam inhalations and steroid nasal sprays. Decongestants and steroid nasal sprays can also be advised. Hope this information helps. Thanks and regards, Honey Andean Aurora.
