[|Human|] hi my dentist gave me cephalexin 500mg for tooth infection ,though I think its a sinus infection, : stuff nose face swelling , teeth pain and swelling , sensitive to hot more than cold . it started out 5 days ago , it started with teeth pain and clear liquid driping from nose . I called dentist ,though no one was open due to the holidays so I found one that gave me a prescription from the details I gave him. I did not take it until I got back in my home town when I saw the dentist and he said I should take the antibiotic  until I can see a specialist. I dont want to pay lots of money if its a sinus problem and not tooth infection. it is the #2 right upper tooth and the one next to it is sensitive as well. what is you opinion and advise? can this antibiotic help?
[|AI|]  Hi, As per your complaint if there is pain in one or two teeth and if sensitivity is more with hot than cold then it can be probably due to infection in teeth and when the infection reaches deep in to the nerves then there is pain. Secondly at times tooth decay can cause infection in sinuses as at times the roots of the teeth lies deep in the sinuses leading to infection progressing into the sinuses. If there is sinus infection then there is commonly generalized infection in all upper teeth on infected side and not single tooth. I would suggest you to consult an Oral Physician and get evaluated and a Panoramic x-ray and sinus x-ray can help in ruling out the exact cause and treatment can be done accordingly. In either conditions antibiotics is helpful therefore you can very much take it now. In case if deep tooth decay is ruled out the Root canal treatment of teeth or extraction of teeth depending on condition of tooth can be advised. In case of sinus infection, antibiotics, painkillers, decongestant nasal Chat Doctor. Hope this helps. Let me know if I can assist you further.
