Complications
By Mayo Clinic staffA tooth abscess won't go away without treatment. If the abscess ruptures, the pain may decrease significantly — but dental treatment is still needed. If the abscess doesn't drain, the infection may spread to your jaw and to other areas of your head and neck. It may even lead to sepsis — a widespread, life-threatening infection.
If you have a weakened immune system and you leave a tooth abscess untreated, you're even more at risk of a spreading infection than is someone with a healthy immune system.
