I was looking for a sonic brush or something similar and these came up. Looked interesting so decided to try since they are cheap and had nothing to lose. OMG ! Best buy ever !!! My teeth have never felt cleaner. I suffer from gingivitis and since I started using my sensitive gums have stopped bleeding.
Just like all of the other reviewer said it does kind of feel weird when you brush your teeth. It feels like you�re brushing your teeth with a sponge.
But my teeth did feel pretty clean afterwards.
They DO feel like brushing with a sponge, so I tend to put more pressure down on them. So far, they aren't getting misshapen. I am happy with them, and probably won't go back to regular brushes again. My dentist recommended these because of receding gums.
