I bought a Phillips Sonicare toothbrush several years ago, when my dentist and hygienist highly recommended it. They stated that they had seen noticeable improvement in their mouths as well as the mouths of the patients that had started using it. After using it for one month, I could already notice a big difference. My teeth looked whiter and my gums looked healthier.


There are several benefits to using the Phillips Sonicare Advance 4700 rechargeable toothbrush. Using this toothbrush makes your teeth whiter because it greatly reduces tobacco, coffee and tea stains. The Phillips Sonicare Company even offers a money back guarantee, with no questions asked, if you don't notice an improvement within 28 days. Another benefit is that it has been clinically proven to reduce 20% more plaque than a manual toothbrush and it has softer bristles, so you don't have to use as much pressure on your teeth and gums. In my opinion, the most important benefit that this amazing toothbrush offers is that it makes your gums healthier. By having healthy gums, you greatly reduce your risk factors for gum disease and bone loss.

How It Works

The Sonicare toothbrush was invented by a team of periodontists (dentists that specialize in the treatment of gum disease) and bioengineers at the University of Washington. The Sonicare toothbrush has a built in microprocessor that allows the bristle tips to move 3 times faster than other electric toothbrushes while moving in the back and forth motion that is recommended by dentists. The powerful cleaning action of this toothbrush gets plaque below the gumline as well as deep in between the teeth.

Our mouths are divided into 4 sections (quadrants), which consist of the upper left teeth, upper right teeth, lower left teeth and lower right teeth. The Sonicare Advance 4700 has a built in timer that goes off every 30 seconds for up to 2 minutes. This allows you to spend 30 seconds brushing each quadrant for the full 2 minutes that most dentists recommend.

Special Dental Conditions

If you or your child wear braces, this toothbrush has been clinically proven to reduce more plaque and gum irritation around braces than a regular toothbrush. Bad breath is another dental condition that is greatly reduced or eliminated by using the Sonicare Advance, because most cases of bad breath are the result of unhealthy gums or gum disease. Dry mouth is a dental condition that can also lead to gum disease and cavities because of the lack of saliva. The Sonicare toothbrush actually stimulates saliva in the mouth to help with the prevention of gum disease and cavities.


The suggested retail price of the Sonicare Advance 4700 toothbrush is $109.99. While this may seem like a lot to pay for a toothbrush, it is an investment that you will not regret. The Sonicare Company recommends that you replace the brush heads on this toothbrush every 6 months. The brush heads for this toothbrush come in a pack of two and usually retail for $29.95. They are also color coded so that everyone in your family can use the same toothbrush, simply by changing out the brush head. When you factor in the amount of money that you will save on dental treatment, this toothbrush is highly affordable.
