My youngest has all her front teeth and is currently working on her molars. We were using a plain old bristle toothbrush for her, and it was a battle to brush her teeth. It finally dawned on me that she fights so much because it probably hurts. So I stumbled across this and decided to give it a try. Game changer. Not only can I now brush her teeth without having to pin her down in the most loving way possible, but she constantly begs to brush her teeth. It must feel really good on her gums because she’ll let me keep brushing back there really good. My one complaint is that the guard can come off easily, but I do like that it’s removable because it’s easier to clean.
