<human>: I had two teeth extractions this past Wednesday. I developed a canker sore on the inside of my upper lip . The dentist said it was caused by the Novocain. Right above where I had my tooth extracted there is a hole on my gums. He had to use several equipments to try to remove the root. My question is, can a canker sore cause a hole on your gums? The hole is pretty deep and it s not white like the canker sore right above it. Could it be from the sore? What caused the hole if not? And will it close?
<bot>: Hi, Thanks for asking the query, Canker sores occurs due to physical or chemical trauma. The hole in the gum is due to healing extraction socket, usually it takes 8-10 days after extraction for the socket to heal completely. Maintain a good oral hygiene and prevent the site to get infected. Use chlorhexidine mouthwash gargles twice daily. Apply colonel oral ointment topically over canker sores. Hope this helps out. Regards.
