Review: Cheaper than a filling & totally worth the investment after 9 months of use - My dental hygienist recommended this toothbrush about nine months ago. When I mentioned how expensive it was, she said, “It’s still cheaper than getting a filling.” That changed how I looked at the price, so I went for it. The guided brushing app takes the guesswork out of whether I’m actually brushing everywhere. I used it twice a day in the beginning, which really helped me build better brushing habits. Nine months later, I don’t use the app every time anymore, but I still check in here and there to make sure I’m staying on track. The pressure sensor is also super helpful! My dentist mentioned that many people damage their gums and teeth by brushing too hard, and this makes it very obvious when you’re using too much pressure. I’ve had two dental cleanings since switching, and both were probably the quickest I’ve ever had. My dentist and hygienist said everything looked great with very little cleaning needed and mentioned they commonly see this with patients using an Oral-B iO. The brush heads indicate when they need replacing, which for me has been roughly every three months. They’re about $10 per replacement head, so that’s another ~$40 a year to factor into the cost. Not cheap, but reasonable enough for me considering how well the toothbrush has performed. My only complaint is that it’s can be a bit messy. Even after rinsing the head and shaking off excess water, some water/toothpaste tends to run down the handle once it’s on the charger, so I clean the charging base a couple times a week. It’s definitely an investment, but after nine months of daily use and two great dental checkups, I’m very happy I bought it.
