There is a little green thing in the hole left behind after tooth removal. What is it?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I had a tooth removed from the back left of my mouth two weeks ago, and I have been doing everything the dentist told me to do, but I looked in it before, and the hole is white, but there is a little green thing in the shape of a square sitting on top, which I think has been there since the tooth was removed. I was just wondering if you had an idea what it might be because I have looked online, and I cannot find anything, and now my brain is making me think it is something bad.

Please help.

Hi,

Welcome to icliniq.com.

When a tooth gets removed from the socket, it is kept open for healing. By the time you start eating food, it is possible that a particle of food might get stuck in the wound, which is very common. And if it is painful in the mouth opening, then it could be a dry socket. So, please consult your dentist to check out clinically.

I hope this helps you.
