I prefer to keep my teeth. After a second root canal last year, I still had problems with the tooth, so my dentist scheduled an extraction two weeks from tomorrow. I’m taking antibiotics, and my teeth feel fine now. Did antibiotics cure my tooth infection this time? Do I still need the extraction? Thanks. Dakota from PA
Dakota,
Antibiotics can reduce the symptoms of a tooth infection, but they can’t reach the inside of the tooth to remove the infection. In most cases, after you stop taking antibiotics, the infection eventually returns, sometimes more aggressive or less responsive to the same medication.
Why Is Removing the Tooth Necessary?
Because the infection remains inside the tooth, you will need root canal treatment unless your dentist determines that the tooth is unsavable. In that case, a dentist will recommend tooth removal and replacement.
What If Symptoms Return Before Your Appointment?
When root canal treatment fails, your dentist may recommend tooth removal
If your pain or swelling returns before your next dental appointment, contact your dentist immediately so they can control the infection until treatment.
Staying ahead of the infection allows local anesthesia to work properly when it’s time for your dental procedure. Infection can interfere with numbness, making treatment more difficult.
Why the Timing of Treatment Matters
Ideally, the dentist begins antibiotics to calm the infection and then removes the tooth within a specific window—usually several days later, once the inflammation has improved.
In most cases, this is the sequence of treatment:
- Start a course of antibiotics (often around 10 days)
- Plan the extraction in four to seven days, when the infection is better controlled
- Extend antibiotics if needed to last through the procedure or beyond
Waiting several weeks for the procedure creates unnecessary risk. If scheduling becomes difficult, your dentist should help arrange care sooner, in their office or through a referral. Prompt treatment leads to a more comfortable and predictable outcome.
