I have had a tooth distracted 1 week ago n still hurt really bad in my head, ear n through, went back to dentist but still hurt! is that normal?

Probably not: Keeping in mind that everybody's pain tolerance is difference, i would say this probably isn't normal. Could be a dry socket, or if you had a prosthesis placed in the area, it may need to be adjusted. Also possible for small fragments of bone to work their way out after the extraction, but if i had to guess, either a dry socket or an infection would be at the top of my list.

Could be TMJ related: If a dry socket is ruled out and the pain is generalized, you could be experiencing myofascial pain dysfunction which basically means that the mucsles that control your mandible were overworked and are in spasm. Usually nsaids and heat will alleviate the pain and over a few weeks the discomfort will subside. It is essential that you seek follow up with your dentist.

Probably Dry Socket: If you have severe discomfort a week after an extraction you may have an infection of the socket- its called osteomyelitis otherwise known as "dry socket". This is something that can be treated by your dentist or an oral surgeon. The good news is that it will go away. Dry socket is unpredictable and not caused by anything that the dentist did, it's just the way that your body reacted.

Many possibilities: All my colleagues gave you reasonable possibilities and i agree with them. What is important is that you should be feeling better each day and the dentist who actually extracted the tooth should be the best one to know what is the most likely cause of your pain and about how long it should take to go away. If not, consider seeing another dentist for second opinion.

Perhaps not: If a rather invasive extraction of a lower third molar, it may be reaching the end of a normal healing/pain cycle. If it was a routine extraction it is possible that the clot was dislodged and a dry socket is causing you significant pain. Also, if IV sedation was used, it is sometimes found that over-stretching of your jaw muscles may have caused temporary inflammation of the jaw joint(s).
