You had a back tooth extraction 3 days ago but it is really sore and swollen you there bad taste in your mouth seems to be getting worse?

It is normal for a back tooth extraction site to be sore and swollen for a few days after the procedure. However, if the pain and swelling are severe or worsening, it is important to see your dentist or oral surgeon as soon as possible. Additionally, a bad taste in your mouth that seems to be getting worse could be a sign of infection. It is important to keep the extraction site clean and to follow your dentist's instructions for post-operative care.

Here are some tips to help manage pain and swelling after a tooth extraction:

* Take pain medication as prescribed by your dentist.

* Apply a cold compress to the outside of your face near the extraction site.

* Elevate your head and keep your mouth open when lying down.

* Eat soft foods and avoid chewing on the side of your mouth where the extraction was performed.

* Rinse your mouth gently with warm salt water several times a day.

* Avoid smoking and drinking alcohol.

If your pain and swelling do not improve within a few days, or if you develop a fever or chills, it is important to see your dentist or oral surgeon immediately.
