Love this toothbrush! Does a great job!

I love this toothbrush. Does a fantastic job of cleaning my teeth. Just had my teeth cleaned and the hygienist said she wished all her patients teeth were as clean as mine! My only wish for the toothbrush is some kind of silicone handle. Maybe silicone grips circling that smooth handle. I’m 73 and have had numerous hand surgeries, trigger finger and carpel tunnel and Dupuytrens contractures. I find the handle gets very slippery while brushing my teeth. I don’t have the hand strength I used to. I use a wide rubber band around the handle now. This is my 3rd Philips toothbrush, I dropped one in the sink, it landed on the head and quit working. I can’t be the only one with hand issues, right? Please think about it.

Pros

Cleans my teeth very well. Love the smooth feeling after brushing!

Cons

Slippery handle. Would really appreciate a fix for that.

Converted skeptic - does a much better job than I

I love the way my teeth stay almost dentist cleaning clean. Too soon to tell yet about the gum health, but the teeth feel so much better.

Pros

Does a great job. I think (too soon to tell) it will save me money at the dentist over the long run.

Cons

vibration might bother a few - but worth trying it.
