Dull ache in back top two teeth and slight swelling. already had wisdom teeth out and everything was clear at my last checkup.anything to worry about?

See your dentist: to drain the dental abscess. If not treated, a serious dental abscess can eventually kill. The infection may spread to your jaw, cheeks, sinus and to other areas of your head and neck. See any dentist for examination, x-rays and treatment. Remember, the only way to cure a dental abscess is with dental treatment.

Re-evaluation: How long ago was your last check up? Even if it was last week, something is different today to cause that swelling. A trapped food particle? A loose filling? A piece of calculus? An undetected problem? Have your dentist take a look....

Dull ache: Your symptoms indicate an infection. This needs to be treated or it will get worse. Things have changes since your last checkup. See your dentist ASAP.
