The “ deep cleaning “ is called planing and scaling.
For most of my life I had horrible, bleeding teeth cleaning sessions so I started to skip them. A friend who was a hygienist started working for a new, much younger dental'practice that was very on top of all things new and required his staff to keep up.
My return required the planing and scaling which was done in 2 sessions. I did not have swelling, tenderness or pain after each one.
After the the final session, they gave me a WaterPic to clean my teeth. I put a little Crest non-alcohol ( no burning) mouth wash in the water reservoir every night.
My dental cleanings have gone from dreaded sessions to a breeze. At 73, WaterPic is all I use.
So good luck with the P & S: you will be amazed at how much improved your dental health will be. Too, infections can start at the gums and cause damage elsewhere in the body.
E.g., a close friend needed to be on an IV drip confined to bed in her living room after her second knee replacement started to act up quite a bit after it was in place. They figured out the starting site of the infection was the gum line. Before they could go in and repair the knee, she had to have gum surgery to reduce or prevent re-infection.
Also, if there is a cardiac issue, the gum line may cause problems with infection. Scary thought: our brains are really very close to that sight !
