I’ve bought this toothoth to replace my oral-b Io 3 toothbrush. It’s amazing. My dentist will be pleased with me. Since using my oral-b 3 toothbrush I’ve never been to see the hygienist and my dentist says I would put her out of a job as my teeth a very clean no decay. With my Oral B io 10 I’m brushing my teeth better with using the app. I’m usually all done by about 3 mins. With the app the teeth Cinders · very.co.uk

I bought this as a gift for my daughter who is absolutely crazy for anything purple. While this toothbrush is pricey, it is definitely a value for the cost . This toothbrush was recommended by the dentist (and actually sold in their office, just not this color) to assist people with periodontal disease to better manage their gum health. I know she will like the smart modes she can select from for Cindy · walmart.com
