I have a lower front tooth that has had a concussion.  It isnt loose but has been sore for several weeks and the tissue below the tooth is red and has developed a white spot looking like a pimple.  The pain has decreased since the concussion occurred with the help of advil.  I have not had anything to eat except soft foods for over a week now.  Should I continue with the advil until the redness disappears and the white spot or should I be more concerned?
Thanks for using Chat Doctor. Read your query. The pimple like thing described suggests an abscess caused due the infection from the tooth. I would advise you to visit a dentist and get the needful treatment done after having a radiograph done. Root canal treatment will be required for the complete elimination of infection. For pain, you can continue with Advil, antibiotics amoxicillin for the infection (if you are not allergic to any medicine). Do warm saline gargling. Hope this was useful. Thanks and regards.
