Can a tooth abscess be cured via antibiotic injection in situ? I want to avoid tooth extraction.

Hi, I will have my upper left premolar extracted tomorrow due to an abscess. I was wondering why an antibiotic cannot be injected on the site and treat the infection around the root instead of removing the tooth. I will be left with a huge gap because my molar was wrongly extracted since the dentist assumed the pain was coming from a sensitive nerve (it was alive) last year but now it seems the problem was the premolar which is with a crown and had a root canal. They also performed my sinus (OC) and now the risk of happening the same is very high. I cannot see a specialist who will do re-root canal to try to save my tooth. Please can you help me with an advice how to preserve my tooth? Why injecting antibiotics is not usually considered? Is it because the bacteria make a biofilm and cannot be targeted? Thank you!

Answer: Can An Abscessed Tooth Be Cured With Antibiotic Injection

By BracesInfo.com Expert 10

Unfortunately there is not enough blood supply to our teeth for them to heal on there own. Antibiotics will only temporarily treat the symptoms, however the source of the infection (tooth) will continue to thrive until the tooth is removed. This is why a tooth cannot repair itself from decay. If the tooth were able to repair itself, like our skin for example after a cut, there would not be a need for fillings or other restorative treatment. Science and medicine are constantly evolving, so maybe in the future there will be advances, as of now its not available on that level.
