Had tooth #13 pulled 3 weeks ago. simple extraction, healing okay. the 2 adjacent teeth have been sore and sensitive ever since. does this seem normal?

Yes: It is very possible that during the extraction, pressure was exerted on the adjacent teeth causing temporary soreness. If it does not improve over several days, you should contact the surgeon.

Yes: There may be some root exposure that may lead to this soreness and sensitivity. I would have it evaluated by a dentist.

Perhaps: It is common for teeth adjacent to an extraction site to be sore for a short period of time. However, 3 weeks would seem longer than average. You should follow up with the treating dentist/oral surgeon to have the area evaluated.

Go back: Make sure there was nothing but irritation to the adjacent teeth. They should be getting better everyday.

It is normal: After an extraction it is not uncommon for the neighboring teeth to be sensitive and even a little loose. This is generally caused by the forces of the ext process. Also the gum tissue is going to move on the neighboring teeth as well which can expose additional root surface. This part of the tooth can be sensitive to cold, hot and sweets.

Yes this is normal: Sometimes the adjacent teeth close to where an extraction of a tooth was performed can become sore and sensitive. If there are cavities or gum diseases on the adjacent teeth, then see your dentist to have them treated. Contact your dentist for a follow up visit from the extraction of the tooth.

No and yes: It is not uncommon for dentists ti use adjacent teeth for leverage. It is not a good idea but many do this. Hopefully the dentist did not luxate the adjacent teeth and tear the nerve at the toot apex. Sorry you are going through this. This is why I use the european ogram technique. It uses different instrument system that does not allow this to happen. Hopefully you do not need root canal.
