Any dentist out there?

That’s what I thought. It was a periodontist examining. He literally jabbed his tool on two places. It felt like he was tearing out the gum. On the second one he went in deep and then twisted. I am new in the area. This is the first time to the dentist. His treatment plan is to remove two teeth. The X-ray taken in January doesn’t show bone loss as far as I can tell. The new one from the other day shows almost complete bone loss. Yet the teeth are firmly in their place, not loose. I don’t know how these things go but, there was no bleeding ever. If the infection was so bad, shouldn’t there be a lot of bleeding? Also, if it is all infected, would I feel it when he went deep in? It hurt pretty bad and I have a high pain threshold. I’d think it’s the healthy tissue that feels the pain.
