Will a dental abscess go away on its own?
No. An abscess will never heal by itself. The pain might stop if the infection kills the nerve in the tooth, but the infection is still there and will continue to spread and cause damage.
What happens if the abscess bursts?
If the abscess bursts, you may feel a sudden rush of salty, bad-tasting fluid in your mouth. The pain may get better, but you still have the infection. You must still go to a dentist right away.
Can I just take antibiotics?
Antibiotics will help stop the infection from spreading, but they cannot fix the source of the problem. The dentist must still drain the abscess and treat the infected tooth, or the abscess will come back.
