My dentist recommended me using an electric toothbrush, I chose the Oral B rechargeable electric toothbrush as it was better in built quality than colgate! it cost me 499 rupees and I have been using it since one week. It takes a couple of days getting used to it, but I have to say it cleans teeth like a pro!
The top head spins at a high RPM and the other bristles vibrate cleaning the tartar deposits with so much ease! the battery lasts for a week and easily plugs in to re charge. The use is simple and the brush is totally worth its price, I will definitely recommend it to everyone!
