The best thing I have done for my teeth and gums is change to a silica toothpaste. I had receding gums, sensitive teeth near my gums that would feel like an electric shock when I brushed my teeth. I also had bleeding gums if I did not religously floss my teeth every night. Since changing, the sensitivity has gone, and my gums don't bleed even when I don't floss every night.
