i have a small hole at the back of my lower left jaw tooth. it was a bit inflamed but was on antibiotic for a nasty flu and sore throat. i gargle with salt water and used a mouth wash . it is not painful just uncomfortable now.
Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint black discoloration and small hole in the tooth is a clear indication of infection in the tooth causing tooth decay. As the infection seems to have progresses leading to nerve exposure or the infection is very close to the nerves causing sensitivity or discomfort. I would suggest you to consult an Oral Physician and get evaluated and a thorough clinical evaluation and x-ray has to be done. In case if decay is superficial and not involved the nerves then filling with tooth colored filling material will help. In case if the decay has involved the nerves then root canal treatment followed by capping of tooth has to be done. Hope this information helps. Thanks and regards. Chat Doctor.
