Tooth and Mouth Problems

I went for tooth replacement (removal of my old crossed tooth and replaced with 5 tooth). Underneath those tooth frequent calcium deposits and it's often pain. Cleaning of tooth is pain as I have sensitivity. Even though I did brush 2 times a day, the deposit is very high. How it can be prevented. And I am having bad odour which my wife complaints.

I have multiple dental problems on left upper jaw. My 6 was removed recently due to infection . My 5,4 were RCT ed and were brittle . Since 5,4 were too weak to support a bridge , doctors did RCT on 7,8 and now suggest to remove brittle tooth 5,4 . Also to support the bridge , they say to do RCT on canine (3) , so they can use it for support and make bridge of 6 tooth's. I am.bit worried about touching a good cannine tooth . It is healthy and strong . Is it compulsory to do RCT on good tooth used for bridge ?
