Philips Sonicare DiamondClean Smart 9700 Electric Toothbrush, Sonic Toothbrush with App, Pressure Sensor, Brush Head Detection, 5 Brushing Modes and 3 Intensity Levels, Lunar Blue, Model HX9957/71

Some 5 years ago, I went to the dentist one day and discovered I had a lot of cavities all of a sudden. After having the cavities corrected and receiving fillings in numerous teeth, I decided to embark on a journey and do everything I could to ensure that I would prevent getting cavities in the future. I had been brushing at least twice a day, but I had not been flossing regularly or doing anything else. I started flossing and using fluoride mouthwash after my routine. One thing I kept putting off was buying an electric toothbrush. I had read conflicting information about whether or not it made a difference. All through this time span, I had been using Oral-B Pulsar vibrating manual toothbrushes. I could not conceive how a Sonicare toothbrush would provide THAT much of a difference. After all, I was used to having a really clean mouth every night and morning with my flossing, brushing and rinsing routine I had developed. For years I couldn't justify the expense of buying a toothbrush that costs astronomically more than what I had. After years of debating it back and forth, I finally decided to make the plunge and see what the top of the line model could do.All I can say is that after a week of owning the Sonicare 9700 Diamondclean Smart, all my skepticism and assumptions turned out to be wrong. The results from this brush are simply incredible.Many reviewers have said this, but I'll say it again. Consider how clean your teeth feel after going to the dentist, then think about what it would feel like if there was a notch ABOVE that. This is literally how clean your teeth feel EVERY TIME you use this toothbrush. I'm completely blown away by how good of a job it does. I'm kicking myself for not buying a Sonicare toothbrush sooner. After using this brush just once, my teeth feel glossy in a way that I didn't think was possible. The biggest difference I've noticed is that the facets of my teeth are clean in a way that simply isn't possible to achieve with a manual toothbrush. I didn't know teeth could feel this smooth. If guided properly, the 9700 will polish and remove plaque from all the little nooks and crannies on, in-between and around your teeth. Your gum-line is stimulated and feel "tighter' around your teeth because they are being cleaned so well next to your teeth. It does all of this and with much less effort than a manual brush. Remember, this is after 1 WEEK, of use.Additionally, the 9700 is extraordinary at teaching you how to get the most out of it. The companion smartphone app is comprehensive and can help motivate some folks with goal selection and other wizardry while you brush. In all honesty, this isn't totally necessary, but it's cool that it can do it.The pressure sensor is a great feature and gives me peace of mind that I'm not damaging my gums or enamel with this powerful mechanical device. You might be surprised about how hard you were brushing before versus what is actually appropriate.The inductive charging feature in the glass is convenient. Just make sure you don't break it. There is a secondary dock you can use if that were to happen, though.Many reviewers have complained about not having a place to store brushes; however, they are packaged in plastic bags, so I'm not too concerned. This likely isn't an issue for me because I am not sharing the brush with anyone else, nor am I swapping out different head types in my routine. Your mileage may vary depending on your priorities.I'm eager to see how this brush holds up and what my dentist thinks in a few months. If you've never used an electric toothbrush before, don't wait years like I did. The cost is well worth it.

First off let me say that after growing up in the 90's the thought of spending $300 on a toothbrush is absolutely ridiculous - until I bought one. The day I received it in the mail, I couldn't wait to get it out and use it for the first time. I had never used a toothbrush like this one before. I usually used the cheaper $10.00 battery powered toothbrushes that you throw away once its depleted. The directions recommend you to let it charge for a full 24 hours prior to using it - however in my case I had already thrown my toothbrush in the trash, and the excitement of the product forced me to use it immediately. When I opened up the package, I was quite surprised of the quality of not only the packing, but the classy display of the contents and the quality of the materials. I picked the toothbrush up - Wow! Never thought I'd be saying this, but "What a beautiful toothbrush" is exactly what I said. The different brush heads are packaged nicely in their separate "baggies". I got the charging base and glass cup out of the packaging, and set it up like the directions say. I set my toothbrush in it and voila! The brush beeps/vibrates twice to let me know it is charging. The battery indicator blinks when the unit is charging. Just like the description says, you get several brush heads: Whitening, Clean/Deep Clean, Gum Care, and one tongue brush. Each brush head is marked on the front of the neck which one it is (C - For Clean) (W - for whitening) and (G - for gum care). If you still aren't sure you can always just place the brush head on the toothbrush and it'll "magically" tell you which one you're planning to use. Another neat thing I noticed is each brush head (that comes in the package) has a microchip, so not only does the toothbrush know which one you're using, it also knows the best intensity and vibration pattern to use which cooresponds with each head. Granted you can change it up anytime you like during the process (brush cycle prior to brushing, intensity while you're brushing), but I thought it was an ingenious idea for it to be this smart. I got the app downloaded, set up my profile, and was ready to brush. I picked the toothbrush up out of the glass - immediately it lights up. I place the "Clean" brush head on it, and the app automatically switches to the "clean" mode and opens up the brush screen - all without me lifting a finger (granted this only works if the app is already open prior to picking up the brush or turning it on). So I turn it on, the app starts telling me the parts of my mouth to brush, and I go to work. The feeling of using this toothbrush vs what I was used to definitely was an awkward feeling - yet it was quite pleasant. I finish the cycle, and then the app proceeds to tell me areas of my mouth I didn't brush as good. It says "Turn on your brush to touch up". I push the Botton and brush exactly where it tells me to. Once the cycle is finished it tells me I did a fabulous job. It reminds me to rinse, floss, and use mouthwash. I've been using this toothbrush for almost a week now and I can already say I'm in love with this thing. My teeth feel as if I've just left the dentist's office. They're already several shades whiter. I'm in love! I will never own anything else other than this toothbrush.
