What is the Silk'n SonicSmile Plus?

The Silk'n SonicSmile Plus is a sonic toothbrush for cleaner, whiter teeth. It removes plaque effectively, making gums healthier and teeth visibly whiter.

Why should I use a sonic toothbrush?

Studies show that a sonic toothbrush is able to clean teeth far better than a manual one. A sonic toothbrush creates vibration, driving mouth fluids (such as saliva and toothpaste) into areas between the teeth and below the gum line, resulting in cleaner teeth. Many sonic toothbrush users therefore state that their teeth feel cleaner and appear whiter. In addition, many people find it difficult to keep brushing with a manual toothbrush for two minutes, even though this is recommended by dentists all over the world. With a sonic toothbrush people usually brush for longer, since it's more convenient. Many of us also brush too hard when brushing manually, which can damage the gums and enamel. Furthermore, a manual toothbrush can only make a few hundred movements per minute, well below the number of movements achieved by sonic brushes. Many dentists recommend switching to electric brushing, simply because it offers more advantages.

How many settings does it have?

The SonicSmile Plus has five settings: Clean, White, Sensitive, Polish and Massage. The Clean setting is suitable for daily teeth cleaning. The White setting can be used to tackle stains and whiten the teeth. The Sensitive setting is used for a gentle yet thorough cleaning of sensitive teeth and gums. Go for the Polish setting to polish your teeth and the Massage setting to gently massage your gums and to improve gum health.

How many vibrating brush strokes does it deliver?

SonicSmile Plus delivers up to 48,000 vibrating brush strokes per minute.

How many times can I use SonicSmile Plus on one full charge?

When used twice a day for two minutes in the sensitive mode, the battery lasts for up to 90 days on a single charge.

What is the interval timer for?

After every 30 seconds, the brush automatically indicates that you can switch to the next quadrant of your mouth. This feature helps you clean the next section as thoroughly as the previous one and for the same amount of time. After two minutes, the recommended brushing time by dentists, the SonicSmile Plus stops automatically.

Does it use batteries?

No. The SonicSmile Plus does not use batteries. It is charged via an inductive charging cradle that is included in the package.

Can I buy new brush heads?

Yes, new refill brush heads can be purchased via www.silkn.eu. The SonicSmile Plus has the same brush heads as the Silk'n SonicYou. The fading bristles will change in colour, indicating when it is time to fit a refill.

Can I use it under the shower?

Yes, Silk'n SonicSmile Plus is 100% waterproof (IPX7).

Rated 2 out of 5 by Jon from Not repairable Yes the toothbrush is well priced and does the job. However, after a couple years the battery lasts only for a single use and there is no repair service.

Rated 5 out of 5 by Shirley from Great toothbrush! I bought this toothbrush a few months ago & I must say I'm very happy with this product. One of the most impressive features of the Silk'n SonicSmile Plus is its long battery life. With a single charge, this toothbrush lasted for over 2 months, making it perfect for travel or for those who don't want to constantly recharge their toothbrush like me!

Rated 5 out of 5 by Katrien VR. from Highly recommended for everyone! I have been using the toothbrush for several months. The battery lasts for a long time. It is good to use and use the different functions. I use all of them because I think it adds value. My oldest daughter of 10 also used it once and she thinks it works very well. She would like to have one for herself.

Rated 5 out of 5 by Tim S from Great new asset Great new asset in my toilet kit! First electric toothbrush (never had much faith in them) but I'm sold. It's a bit getting used to brushing electric in the beginning, but now I'm all for it. Have a nice clean feeling every time thanks to the different settings and the battery lasts forever! On top of all that: 10/10 for design!
