Oral care with enhanced performance.
Do you keep your hair looking beautiful every morning?
Has that same care ever extended to your teeth?
The SOLADEY 5 generates electrons using light and water,
and brushes away plaque as you brush.
Then it keeps plaque from building back up.
The power of chemistry, built into your daily oral care.
A toothbrush that performs as good as it looks.
Design
Gentle. Sharp. Beautiful.
Toward a design that fits
naturally into everyday life.
Functionality and everyday living. Advancement and approachability. The SOLADEY 5 brings the future of oral care into the present.
-
The design theme is "egg shape" — curves and ovals chosen to give an advanced design a familiar, comfortable feel.
-
A stainless steel body that helps carry electrons through to the brush, for a toothbrush that delivers on both quality and performance.
-
The sides are gently bulged as well, so the shape fits comfortably into your hand as you hold it.
-
Soft curves extend to the solar panel too — a design built to fit naturally into everyday life.
A carefully considered shape
makes brushing even easier.
A streamlined form focused on ease of grip. Rounded so it sits comfortably in the hand of anyone, from children to adults. Holding it so your fingers touch the stainless steel body helps transmit electrons into your mouth, supporting brushing with the power of chemistry.
Designed with ease of grip in mind
The conductive area (the stainless steel body), which promotes conductivity through your grip, is 79% larger than in previous models. With more surface area to hold, the body is easier to grip than before.
Conductive section (stainless steel body) area increased by 79%; solar panel daylight area increased by 63%. *Compared with our previous products.
Recommended ways to hold it
With the wider conductive section, both a pen grip and a palm grip can carry the electrons generated by the solar panel through to the brush.
-
Holding it like a pen: "Pen Grip"
With adjustable brushing pressure, this grip helps you avoid brushing too hard while covering every corner of your mouth.
-
Palm grip: held with the whole palm
You can also use it the way you normally would. This grip is recommended for brushing the molars.
Colors
Made for every day. Available in colours you'll love.
Features
Thoughtfully designed to last.
A design unlike any other toothbrush, bringing the power of chemistry into your daily brushing.
With a replaceable-brush system, a stainless steel body, and a solar panel, the SOLADEY 5 has a completely different design from other toothbrushes, built to support your daily oral care.
How it works
Powered by Light & Water.
Uses the power of chemistry to help remove plaque.※ ※ Plaque removal happens through brushing.
The SOLADEY series lets you brush without toothpaste. The built-in TiO2 semiconductor and solar panel react with ordinary water and light to generate electrons. Brushing while touching the stainless steel body carries those electrons into your mouth and to the plaque built up there. The power of chemistry, elevating your everyday brushing.
How plaque removal works
Easier to hold, and smoother on your teeth.
A larger stainless steel body and solar panel make the SOLADEY 5 even easier to hold and brush with.

Results
A Cleaner Feeling, Every Day.
1 Brushes away and chemically helps break down stubborn plaque
In a four-week in-house comparison between a regular toothbrush and the SOLADEY, plaque levels showed almost no change with the comparison brush, while the SOLADEY group showed a 42.7% reduction.*Clinical trial on plaque removal, conducted by the Department of Dental Treatment for the Disabled, Osaka University Dental Hospital.
2 Helps break down the lactic acid that erodes enamel
Plaque uses sugars in the mouth as food, producing lactic acid that erodes teeth over time. SOLADEY helps break this lactic acid down over time. *Lactic acid pH-change experiment, per Sumitomo Chemical Analysis Center Co., Ltd.
3 Helps suppress bacterial growth
After soaking a regular toothbrush and the SOLADEY in a bacterial culture medium for 3 minutes, both were incubated on agar for 48 hours. SOLADEY suppressed bacterial growth. *Sterilization effect test conducted by the Japan Food Research Laboratories.
Replacable brushes heads
A point-shaped tip brush that catches the spots you might miss.
The SOLADEY 5 comes with a point-tip brush designed to thoroughly clean plaque from recessed areas. A thin head (about 4mm) with a 3° slope helps the bristles reach deep between teeth, and the antibacterial design keeps it clean during storage.
Included brush
3-row compact / honeycomb point bristles (antibacterial, medium firmness)
Carefully brushes each tooth, corner to corner. Recommended if you're concerned about missed spots or misaligned teeth.

Brush details
Replace the brush about once a month
After 1 month: bristle tips magnified
A worn toothbrush has splayed bristles and cleans less effectively. The SOLADEY series uses a regularly replaceable head, so you can restore a smooth brushing feel any time.
