Will my gum on the side will cover the hole naturally without need surgery?

My lower molar was extracted. After a week I noticed the gum of inner lateral side of the extracted site has white sharp piece coming out from the gum. I'm not sure if it is part of my tooth left after extraction or the main bone that they damage during extraction. I went to the dentist again. The piece was removed and i was told that they smoothen the part of the bone also. My gum was infected and had anti-biotic. But it still bother me because the gum on the side left OPEN (hole) after they removed the piece and it's about 5mm in diameter and the bone is visible. I dont have gum disease. DOES MY PROBLEM NEED SURGERY OR SHOULD I JUST LEAVE IT? WILL IT HEAL AND THE GUM WILL GROW AND COVER IT NATURALLY? Please reply, thak you.

it should just grow back naturally.... its going to take a while for it to completly heal tho.... just be patient and keep the area clean.....

I'm not comfortable with he bone being visible, but keep your mouth clean especially this area. Since you had an infection, it was probably left open to allow any pus to drain. You can rinse your mouth a couple of times a day with hydrogen peroxide, or Peroxyl which is sold at any drug store.  How long has it been since this was done?

The piece was removed one week ago. The bone was smooth before but now it's getting rough again and the edge of the hole of my gum is a bit still red and soar when applied pressure of my tongue but it's not swelling or painful anymore. Or do I need to go to the dentist and smoothen the bone again? Will my gum naturally heal and cover as normal. Thank you.

I'm using a CORSODYL mouthwash (chlorhexidine digluconate). It's for bleeding gum or irritated gum. Will this kind of mouthwash help of my gum situation?
