The temporary filling came out of my upper left canine tooth, and an abscess formed on my gum. My dentist recommended a repeat root canal to get rid of the abscess. Since the abscess isn’t painful, do I need a second root canal, or will antibiotics work just as well? I would like to move forward with a resolution because I’m scheduled to begin Invisalign in April. – Thanks. Bryce

A root canal removes a tooth infection. A dentist will seal the root to prevent bacteria from re-entering. Replacing the pulp with root canal filler material and sealing it with cement is crucial to the long-term success of the treatment.
Temporary Filling: A Critical Step
A dentist places a temporary filling immediately after a root canal to protect the seal from saliva, which can degrade the root canal’s filling material if exposed.
Risks of Exposure: If the temporary filling falls out or a dentist doesn’t place it correctly, saliva can seep in and compromise the seal, potentially leading to a recurrence of the infection.
Will Antibiotics Get Rid of a Tooth Infection?
Antibiotics cannot reach the inside of the tooth due to the lack of blood circulation there, making them ineffective for treating the internal aspects of a tooth infection. They can only temporarily address abscesses in the gum and bone. The infection will return when you stop taking the medication.
Potential Risks of Ignoring Treatment
Left untreated, infections can spread to critical areas such as the eye or brain, especially infections in the upper jaw.
- Antibiotic Resistance: Misusing antibiotics can contribute to developing antibiotic-resistant bacteria, posing a broader health risk.
- Long-Term Damage: An untreated infection can cause decay from inside the tooth, eventually making it unrestorable, creating the need for extraction and a dental implant.
Ignoring failed root canal treatment poses serious health risks, emphasizing the need for prompt and proper follow-up care, including the placement of a permanent restoration like a crown. Treatment delays can lead to a dental emergency.
If you are hesitant about your dentist’s recommendation, you can get a second opinion from a dentist with advanced root canal training or an endodontist (root canal specialist).

How can I get rid of tooth infections at home? Three of my upper left molar teeth have cavities, but I cannot afford a dentist and do not have dental insurance. The left side of my face has been swollen for over a month. I’ve called ten dental offices within ten miles of my house, but none will accept a payment plan for filling cavities. I have a steady cleaning job, but my credit isn’t good, so I do not qualify for a healthcare credit card Also, I will have to pay for transportation to and from the dental office, so I’m limited in how far I can travel for dental work. How can I care for the infections at home? – Thanks. Lei
I let my dentist remove a wisdom tooth in late July because he said he had removed countless uncomplicated cases. He said he would refer me to an oral surgeon if the case looked complex. My gums closed over the sockets in about three weeks. I feel earaches and eye pain on the left side of my face. I returned to the dentist last, and he admitted that the problem could be from a tooth fragment that he could not remove. He said he could refer me to an oral surgeon if the pain didn’t improve by the end of the month. Why would the pain suddenly improve without any intervention? Should I ask for a referral now or try to get a same-day appointment with another dentist? – Thanks. Chandler from Cincinnati, OH
If my dentist left a tooth root behind after my upper right first molar extraction, do I need it removed? She referred me to an oral surgeon to remove the rest, but they can’t see me until December. Why would my dentist close the gums knowing she left a root behind? Do I really need an extraction, or is this part of the buddy system? Thanks. Diego from Boulder, CO


I have a swollen pocket in my gums that hurts really bad. It has been there for about 4 or 5 weeks. It is worse at night and keeps me awake sometimes. I got a job this past Tuesday, but the dental insurance isn’t active until next month. Will an antibiotic keep any infection controlled until I can see a dentist? I want to limit my out-of-pocket expenses until this job works out for my family and me. Anne from Salem, OR
My 2018 root canal on my lower right molar went smoothly, but since June this year, the tooth has hurt daily. Within the past week, I have taken ibuprofen daily to concentrate on work. The timing of this toothache is in the middle of my plans to leave town next week. How urgent is this issue? I don’t want to say I don’t have time for another root canal, but please tell me if I should see a dentist this week. Thank you. Haley from NH
