I am approaching 80 and my teeth are not good, with some significant gum disease despite my consistent and concentrated efforts to keep my mouth healthy with manual toothbrushes - I had never used electric. My dental hygienist recommended that I use an electric toothbrush, and I chose Spotlight. My first experience was quite uncomfortable, with tingling when I cleaned my top front teeth, and heavy vibration if I let the brush body touch my teeth. I persisted and have now learned to use the brush with (mostly) good comfort. I now first give my teeth a good clean with my manual brush. Every second day I follow up with interdental brushes, and on the alternate days I follow up with my Spotlight; this regime seems to work well for me, and my teeth and gums feel cleaner, fresher, and healthier. I will report separately after my next visit to my dentist....
