It sounds like a root tip or a piece of bone that has erupted. Autumngirl was right, get it with the tweezers.
I had this problem years ago when i had my wisdom teeth out. The dentist had told me to rinse with hydrogen peroxide to bubble stuff up out of tje hole. That didnt always work though so i carefully used a tweezer to oull food particles out. Good luck!
When I had all 4 of my wisdom teeth removed, I found that food used to get stuck in the healing lower gums, and especially rice.
I used to pick it out with a clean toothpick.
If you do have a problem of getting it out, see the dentist to help you to remove it, otherwise it will delay the healing process and it could get infected.
Best wishes.
Hello there,
A clinical examination is important to confirm the exact cause of your symptoms. The longer a food particle stays trapped between the gum and tooth, the greater the chance the gum will become irritated and infected and can become a serious problem if left untreated. You may try rinsing your mouth with warm saline water. This will help in dislodging the food particle. If it doesn’t come out see a dentist. Do keep me posted.
Best luck and regards!
