    Absolutely best toothbrush ever. Teeth and gums feel incredibly clean after use. I had Sonicare 9 years ago and an Oral B the past 6 years. This is a much improved unit compared to those devices. Highly recommend this toothbrush.

    I love this toothbrush ! Yes, it is a little pricey, but it truly cleans your teeth, gums and tongue in a way that will keep you out of the dentist's office. The fact it has an app to help train you as you brush is an added bonus.

    This is by far the best toothbrush I have owned. I have had numerous other models and the cleaning from this one is absolutely the best. My kids have the lower models and like them but with this on... can't go wrong. But price is pretty high.

    Odd to be creating a review for toothbrush that has Bluetooth, but nonetheless it’s awful at connecting to a smart phone. (Yes, I’m running the latest iOS and updated the firmware on the toothbrush) The toothbrush is in our master bedroom bathroom and only connects to my wife’s phone despite my phone being in closer proximity. I’ve tried using it for fun sake but it never connects to my phone. Great for cleaning though

    Best electric toothbrush I’ve purchased! Love the app to see where you are missing and this would be great for kids or someone with braces to be sure they are getting all the spot that need cleaned.

    I debated whether I wanted to spend $300 on a toothbrush but I do not regret my purchase. The included brushes, the app integration/mouth tracking, and the quality of the brush (and charging solution) make this worth it!

    Everything as advertised. Powerful and a great cleaner. It was time for a new Sonicare. My old one lasted years. Hope to get the same good use of this one. Very pricy.

    Honestly, the best toothbrush I've owned. The different brush heads are very convenient. A little on the expensive side. Be aware; if your iPhone is jailbroken, the app will not work.

    I've been eyeing this toothbrush for a quite a while. I was going to purchase it for christmas then my cards got hacked. Until a recent dentist appointment about a month and half a go it was reiterated about using electric tooth brush. What I love about this is the app going section by section. lol I'm not going through fast enough sometimes to cover the sections? I just restart the tooth brush. The app knows what i'm doing. Tells you if your scrubbing or applying too much pressure. The color changes. At the end of each session it asks did you floss? Did you rinse? I think its cool.

    Great Oral Hygiene with Sonicare Toothbrush

    I absolutely love my Phillips Sonicare Diamond Clean Smart 9700 Rechargeable Toothbrush. It does an absolutely fantastic job cleaning my teeth, gums and tongue. a regular toothbrush cannot clean my teeth like my so!nicare toothbrush. It is the next best thing than going to the dentist. I would highly recommend this product to anyone. After using one, you could never go back to a generic toothbrush. It is worth every penny. Taking and keeping good dental hygiene will prevent you from having to get dentures. i personally, prefer to keep my natural teeth as opposed to having to buy/wear dentures. Buying and using a Sonicare toothbrush is the best thing for your oral hygiene!

    I really wondered if getting this toothbrush would worth the money. I alternate between the deep clean and the whitening brush heads. I feel I have seen a difference in my teeth. My dentist even commented that my teeth looked good. I don’t necessarily love brushing my teeth, but it’s a thing we have to do. I would say, it’s definitely worth the investment. Using the app takes, and trying to find the angle they want you to use to brush takes some getting use to. It does have cool features like tracking your use and you can set up your Amazon account to auto refill, if you’re into that sort of thing.

    I love this toothbrush. The app is helpful to teach or retrain someone to stay in one area long enough to actually clean your teeth properly and to look back to see your brushing habits. This toothbrush is totally worth the investment, along with regular flossing and professional cleanings. I love how I can feel the bristles getting between my teeth and gums and they feel much healthier.

    Long term review

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I’ve had this toothbrush about 3 years. It is well made high quality materials, battery still going strong. 2 things that broke, it no longer charges in a cup it came with and pressure sensor doesn’t work. Head that attaches to a brush became loose and it’s very likely to brake soon. Upon checking the receipt I’ve learned it only comes with 2 year warranty which defines not enough especially tooth brush priced at $300. Even though I’ve had earlier and lower end versions of this brush I really don’t think it makes a much difference using this or less expensive brush and I don’t think it’s worth the money. Travel case is really nice though.

    I am loving the product. It helps you realize how much the toothbrush helps you with brushing. The sensor and vibration feature make a significant improvement in my technique. I was scrubbing to much and putting to much wrist action into my brushing techniques. Let the toothbrush do the work.

    I love this purchase. I was lucky enough to get this when the lunar blue color went down to $219, which makes this worth every penny! The features, app, battery life, it’s all engineered and quality of the products Philips makes is top tier. I travel a lot and the charging travel case is key. Protective and easy to charge quickly. They last forever and is a great investment for your oral care.
