What To Look For
Philips Sonicare is a popular, high end brand of rechargeable electric toothbrushes that use a "sonic technology" to create a strong yet gentle vibration to clean your teeth. There are six versions of the Sonicare, designed for different needs. There is a child size Sonicare with a smaller, lighter handle. Sonicare Essence is the most basic model, with a rechargeable battery, charging deck, and two options of brush head size. Flexcare 1 and 2 offer a range of brushing modes for sensitive teeth and gums, and a sanitizer. Sonicare Elite has a special contoured brush head, and an angled neck to reach all areas of the mouth.
Common Pitfalls
Be sure to pick up a few replacement brush heads. Not replacing your Sonicare's brush head frequently enough can compromise its effectiveness. You should change the head every six months or so. Brush heads come in different sizes. Choose the one that is small enough so you can thoroughly brush every tooth, but large enough to massage the gums adequately while you're brushing.
Where To Buy
You can buy Sonicare online through electronics and general retailers like Amazon or NewEgg. In your town, Sonicare products are carried at major big box and department stores around the country, including Best Buy, Target, Macy's and WalMart. If you are looking for a particular model, such as the Elite or Children's Sonicare, you may not find it in every store.
Cost
Sonicare toothbrushes range from $50 for the basic Essence model, to $200 for the Elite. The majority of models are about $70. Replacement heads come in multi-packs costing between $20 and $50 dollars.
Comparison Shopping
Sonicare is just one brand of well-regarded electric toothbrushes on the market. Oral B's Triumph toothbrush comes in a variety of models in a similar price range as the Sonicare. Also a rechargeable toothbrush promising dentist-quality cleaning, Triumph has a small, round head that spins to brush your teeth, rather than the square, traditional brush that vibrates on the Sonicare.
Accessories
You will always need additional brush heads when using Sonicare. You can also replace the charging dock and travel case that come with your toothbrush if needed. Brush head covers for safe storage are available for about $15 for a pack of three. Many people who use these higher end dental care tools also enjoy a water pick flossing tool. A Sonicare UV sanitizer kit is also available, and costs about $12.
Insider Tips
Sonicare can remain charged for up to three weeks, according to the manufacturer. However, the power of the brush declines significantly after a few days without a recharge, and typically does not fulfill a two-minute brushing session within ten days.
