Orthodontic extraction

My little one who is currently undergoing braces

I had a tooth extracted today.

He said that he is only picking 2 today, and plans to pick the remaining 2 later.

But... it's been almost 2 to 3 hours since the extraction.

I am worried because blood is still slowly seeping out.

They said there would be some pain for about a day...

I wonder how painful it must be since a healthy tooth was pulled...

It's a natural extraction for orthodontics, but... why does it hurt my heart so much... ㅜㅜ
