Is this a real ultrasonic toothbrush that uses ultrasound? The frequency seems not right. Ultrasound is at least 20,000 Hz

I can't answer that question but I CAN tell you this is a piece of junk and not worth the money. If you buy it, you can expect it to stop working properly after a year or so.

You can start it for 2 minutes or 2 minutes 30 seconds. It vibrates every 30 seconds, so that you can brush an equal time for top/bottom/right/left. The optional extra 30 seconds enables ultrasound said to whiten your teeth.

I am not sure what you're asking but I WOULD NOT purchase from this company! I bought one through a LIving Social, kept it new in box for a year, to give as a gift to my daughter, and when I presented it to her, it did not work and they would not replace it. They sent me a % off coupon for a new toothbrush, which was ridiculous... why would I buy from this company ever again? I would go with a more established brand that will back up their product. Hope this helps!

I don't know. But I was not happy with the product. I had one for over 10 years and it worked great. Then I bought another and it lost water pressure in a couple of months. I bought another, same thing. I purchased a different model through my dentist with the sonic care toothbrush and I haven't had any issues with it.

it does make a rather high pitched buzzing sound. that is actually the "ultra sonic" cleaning. make sure that you push the start button.

Sensitive CLean is new to me. It might be a marketing gimmick, or it might be a new model replacing the Sensitive. I put the two links side by side in different tabs; there is a difference in how they are constructed. Be sure it fits your power tooth brush. We use the "4000" type. My wife uses the sensitive brush, and has for years; I use one (rarely) if I get a minor gum infection. I doubt there is much difference, but I would go with what my dentist recommended. He probably has a reason; you could ask him/her. I am not much help! These Sensitive-type brushes are designed for people with sensitive gums, and for children. http://www.amazon.com/Oral-B-Pro-Health-Sensitive-Clean-Refill/dp/B008CC3SKW/ref=sr_1_5?s=hpc&ie=UTF8&qid=1402654142&sr=1-5&keywords=oral+b+replacement+sensitive+brush+heads http://www.amazon.com/Oral-B-Sensitive-Extra-Soft-Brush-heads/dp/B00006ANDK/ref=sr_1_1?s=hpc&ie=UTF8&qid=1402654141&sr=1-1&keywords=oral+b+replacement+sensitive+brush+heads

Basically, this is an antibacterial, antitartar/plaque/gum disease preventive-curative/anti-inflammatory to gums and mouth ulcers of an instrument to use. Flossing need not be done, but I do it occassionally, just to make sure. Food particles can get stuck between some teeth, and not others. Ultrasound technology (high frequency sound) can also keep teeth whiter. Consult your dentist, but some are not very familiar with this item, or if they are, may say something to the effect: that more research is needed. Well, I bought it and use it anyway, and so far, I am better off with this instrument for better oral health.

I have the less expensive toothbrush. I am very pleased with it. I can't speak to the more expensive one as I have not used it.

It comes with two brush sizes, the vibration can be a little scary for a little one, gradually move up to putting it in the mouth, I let my little one get used to the soft vibration on the outside cheek lips and mouth. I personally waited until she was a little older for this type of toothbrush. Around 4 yrs old.

Yes, you can!This is my second one, bought a sonic toothbrush for $110.00, was highly recommendedby a dental hygienist,I thought she would be the one to ask.I expected my teeth to feel like they had just been professionally cleaned.I returned it the next day, don't know why people swear by it...The Oral B toothbrush does a much better job!!!

Great question. For now Sonicare only manufactures one type of brsuh head and they do not specify the firmness. As a dentist I would say the that the bristles most closely resemble "soft" manual toothbrushes. The cool thing is that the toothbrush handle has five different settings with the lowest setting being "Sensative". Even patients with sensative gums should be able to tolerate this setting well.

I am out of clarisonic brushes so I can't compare but I think not. I am sensitive to noise so I think if there had been a marked change I would have noticed. Further, I did have a funny, high pinched noise with my generic brushes on my sonic are toothbrush and it did break. I am not having that with these brushes on the clarisonic. Honestly...I think they are better than the ones clarisonic makes. Not better for the price just better. For example I feel that when I 'lock' them into place it is a tighter fit than the clarisonic ones. In fairness, this is my first package and I have only used the first head but I am very pleased and have had no foreshadowing of poor quality control.

It's just a manual toothbrush. And it has some rubber bristles that didn't hold up well. I'm not rough with my brushing.

The original design was to send out true ultra sound and because it does it shuts down after a specific period of time. If you use it barely touching stroking up and down and front And back it will destroy plaque, but you are going to have to change from HARD SCRUBBING or you are wasting your money. 20 yr. USER!

I find no difference with the noise. I have been using the brush for a month and my device seems fine.

I'm not sure, I must admit; my electric toothbrush, Sonicare, Philips, is HX6750; the best thing to do is send an E-mail to the Philips, Sonicare people. I've done that before, and they can tell you for sure. Here are some phone numbers: 1-800-682-7664 (Customer Service) & www.philips.com/support. These should help!

I'm not sure what you are asking. There is no heat involved in the cleaning action which is done with ultrasound waves.
