Bests & Worsts Reviews from Amazon

I waited to post this review until I went In For my quarterly periodontal this week. What prompted me to buy this in the first place was the dental hygienist recommendation to purchase an electric toothbrush and after shopping around this is the best deal in the market. What’s even better is my hygienist didn’t need to use a water pik and just used a dental instrument to clean my teeth as there was hardly any tartar buildup after using this for 3 months. She even recommended that I come in 2x a yr instead of 4x a yr so thereby saving evening more $$ for copays etc. this toothbrush works great and I couldn’t be more pleased with the results. It will give the big guys like sonic care and oral B a run for their $$$....now my wife wants one!! Update: love this toothbrush but now it’s not holding its charge. Can the lithium battery be replaced?
