What is an ionic toothbrush?

The Ionic Toothbrush helps remove plaque and bacteria from otherwise difficult places to reach, by breaking the electrostatic bond of the surface of a tooth.  As a result, this reverses the polarity of the tooth and creates a negatively charged circuit to collect bacteria and plaque.

How does an ionic toothbrush work?

A diagram showing how the Soladey Ion5 works
How it works
  • The ionic action is brought about through a light-activated titanium rod (semiconductor) inside the handle and a solar panel at the end of the handle. When exposed to any light source (a fluorescent bathroom light, a plain light bulb, or sunlight), the photo-sensitive titanium rod inside the Soladey toothbrush converts light into negatively-charged ions (electrons). The stream of electrons is enhanced by the solar panel. The rod releases these ions, which travel out through the bristles of the brush head. The electrons blend with saliva to attract positive (hydrogen) ions from the acid in the dental plaque on your teeth resulting in the disintegration and destruction of the plaque.
  • As a result of the semiconductor rod, super oxide ions are formed which form a layer over the teeth. This makes it more difficult for the plaque  to adhere to the teeth, allowing the teeth to stay cleaner in between brushing.
  • With the ionic action, acids in the mouth are neutralized reducing dental erosion and freshening the breath.
  • One of the main causes of tooth decay is the presence of dangerous bacteria in the mouth made up of over 500 species. The Soladey toothbrush has been proven to be effective against S. mutans, Escherichia coli and ginivalis bacteria, the main contributors to dental caries and gum disease.
  • Toothpaste is not required as water (saliva) is the acting ingredient – oral hygiene now becomes not only natural, but also economical! For those who find it hard to give up toothpaste, use only very small amount! These toothbrushes can be used with small amounts of our green clay toothpowder, our activated charcoal or our walnut bark powder. These toothbrushes can also be used with a mouthwash solution made from our organic miswak sticks and this can be very beneficial to strengthen the enamel and reduce tooth sensitivity. All of these natural dental products are available in our online dental department.
  • Children often swallow a small portion of toothpaste, which may have a negative impact on health from over the long-term. Therefore children should use only the tiniest amounts or toothpaste; this is another reason the Soladey toothbrush is the best choice.

With regular use, ionic toothbrushes can result in cleaner, healthier and whiter teeth.

How to use the Soladey ionic toothbrush

Brush the tongue

After wetting the bristles and semiconductor with water (saliva is sufficient outdoors) brush all surfaces of your tongue without using toothpaste, and especially first thing in the morning after stomach acids have accumulated from sleeping. Brush from the back of tongue (not in the throat!) to the tip of the tongue. You may see discolouration on the bristles (concentrated bacteria and accumulation of acids), and so make sure you rinse bristles with water repeatedly to remove this film. Once you feel the bristles and tongue are adequately clean then you can work on the tooth surfaces as now there will be less concentration of bacteria in your mouth. Bear in mind that the tongue generally carries most of the mouth’s bacteria! Saliva is sufficient for brushing teeth outdoors, but in this case we do not recommend you brush your tongue outdoors without a source of running water available to clean the bristles.

Brush the surfaces of the teeth

Continue to brush your teeth lightly and thoroughly in the same way as with an ordinary toothbrush. Concentrate on contacting the teeth rather than applying force.  Unlike a conventional toothbrush, you do not need to brush with force, and so a medium head will penetrate the spaces in between your teeth more efficiently than a soft head and without splaying. Brushing lightly will also be easier on your gums and help fight gingivitis (gum disease/ receding gums).

Make certain there is an adequate light source (natural or artificial) necessary to activate the semiconductor. If you are brushing the back teeth open your mouth as wide enough so that the available light may reach your back teeth. The best option is to move close to a direct light source which will illuminate the inside of your mouth! The brighter the source the better the result.  You will notice that your saliva will foam slightly when the toothbrush is working effectively.  If you are using toothpaste use very little as this can foam over the rod and block the light.

Brush the gum line

Hold the brush at 45 degrees to the gum line, push the edges of the bristles up against the gums and gently rock the brush against the gum margin, going over each tooth – on the cheek side (buccal) and on the inside surfaces (lingual). Don’t forget to reach behind the back molars.

How to replace the brush heads

To keep the toothbrush operating at maximum efficiency, replace the heads regularly.  Recommended replacement every 2 -3 months or when bristles start to curve outwards.

Pull the head and handle apart along the axis

Insert the head into the handle firmly

Do NOT twist or bend the head and handle during detachment and insertions.

How to clean the Soladey toothbrush

Rinse the brush head and the entirety of the brush after use to remove saliva, bacteria and remains of toothpaste. Periodically (about once a week) pull the toothbrush head off the brush and rinse the titanium rod. Always replace the toothbrush head straight after cleaning to avoid damage to the rod. If toothpaste adheres to the base of the replacement head during use, it can set hard and make head removal difficult, so removed the head and clean the rod to prevent this from happening straight after use.

Soladey toothbrush UK, variations:

Soladey – 3 Toothbrushes in four colours.

Packets of genuine replacement heads (4 in each pack):


  • Soft bristles, best for sensitive teeth, teeth with thin enamel, for troublesome teeth and gums
  • Medium bristles, very good for cleaning the gum line and brushing teeth prone to staining
  • Tapered heads, better for access for crowded and overlapping teeth, for access to rear molars
  • Child heads, as above, also better for children with small mouths and for pet care such as dogs and even cats
  • Honeycomb bristles, medium texture, containing charcoal and silver. Each bristle has a hexagon profile, giving extra cleaning power. The rows of bristles have a raised notch of bristles part way along the brush head which are great for cleaning along the indentations of the molars. The charcoal and silver ions help the brush heads to stay more hygienic between use.

Frequently asked questions

What is the life of the Soladey toothbrush? With proper use, almost indefinitely.

Is the semiconductor safe? Titanium dioxide, the metal from which the rod is made, does not dissolve or corrode.

Will teeth become yellow if not using toothpaste? Reflecting the dentin colour, healthy teeth are naturally off white in colour.  Brushing only with water restores the original colour.  If you must use tooth, only a tiny amount is recommended.

Is there any proof of the effectiveness of the Soladey? Clinical literature is available from dental colleges.  According to studies, toothbrushes with semiconductors  have proven to be as effective as plaque removing tools. We have included some research paper below.

Can Soladey be used to clean fillings, crowns or other dental work? Yes, Soladey will be effect as reducing plaque and provide an anti-bacterial effect even on modified teeth.

Can Soladey be used with braces/retainers? The Soladey with help neutralise bacteria for those wearing braces. Brush carefully to avoid damaging the materials of the braces.  Remove retainers prior to brushing and make sure the retainers have been cleaned before replacing.

When will you get more of the Soladey Ion5?
The Ion5 is not being manufactured at the moment, but the Soladey 3 is the same toothbrush with a slightly less bulky metal handle.

Do you also have the Soladey Sonic Ionic toothbrush? Yes, it has its own product page. Soladey Sonic Ionic Rhythm 2 Toothbrush

What are the main differences between the Ionic toothbrush on this page and the Sonic Ionic toothbrush?
The sonic ionic toothbrush has all of the benefits of the Soladey 3 Ionic toothbrush, but it takes a AAA rechargeable battery which powers the brush head to oscillate at up to 22,ooo revolutions per minute. So the Rhythm 2 has even more cleaning power.

Where are these brushes made?
All of the replacement heads are made in Japan. The Soladey-3 handle unit is made in China, because they are the main producers of solar panels.

    Soladey toothbrush. I have used one of these for years and have very little issue with plaque build up. It helps save the planet as well as my teeth, thank you.

  2. Sally Mittuch

    Thank you Sarah. It is great to hear that you are still using you Soladey brush, even after 20 years. They are very well made and just carry on working. It is great that you are not being sent to the hygienist as a result of using the Soladey toothbrush. That is exactly the position we would like all of our customers to be in!

  3. Sarah

    Nearly 20 years ago I worked at a ‘natural health centre’ near here and purchased from them a Solardey tooth brush. It was when i needed new brush head that I found Natural spa supplies and I have been purchasing your products ever since.
    I quickly felt that my teeth were super clean and for many years my (NH) dentist didn’t send me to his hygienist. Your 2020-2021 dental charts are so interesting. It would be good if I had been able to do a before and after chart but having never used anything other than a Solardey for so long I know that my teeth are in very good order. ( I am 77.)

  4. Julie

    Hi, Further to our chat this morning I thought you might like to know that my oral hygeniest, who is really excellent at her job, is amazed that my teeth and gums are in such good condition as I “only” always use an ionic toothbrush with no toothpaste! You can put this in as recommendation if you like! Enjoy the long weekend, Julie

  5. Christine

    I bought a Soladey toothbrush in the summer and have been using it ever since. I\’ve since paid two visits to the dental hygienist (at a private practice so the standard is extremely high) and the lady can not believe how incredibly clean my teeth are. I showed her the brush (which I use without any tooth paste/powder) and she said she\’ll recommend it to all the staff at the practice! I even use it for my dog – with a different brush head, of course! I highly recommend the Soladey toothbrush. So glad I discovered it.

  6. sarah

    I have bought replacement heads from you, having used a Soladay toothbrush for about 10 years. My teeth always feel and are beautifully clean. I have not been to a hygienist for years, no plaque. Unfortunately my dentist just thinks its my teeth and when I tried to explain he wasn’t much interested. Their training doesn’t encourage them to think that there might be any other way..

  7. Jo

    I have been so very pleased with the results gained through using my Ionic Soladay toothbrush, and so too my dentist! It is much gentler on the gum line than an electric or sonic toothbrush, but I would say definately more effective in cleaning, while keeping enamel intact and away from any apparent need for frantic scrubbing! Inflammation has disappeared, to the point where I had to explain to the dentist what I had been using, later sending him photocopies by post, showing information on how the light activation works. No need for toothpaste either… brushing my teeth has become a simplified joy!
    Josephine from Lancashire

  8. Sally

    I am absolutely delighted with the toothbrush and it has exceeded my expectations. I have been troubled by inflamed gums around my back molars despite brushing scrupulously with an electric toothbrush, interdental brushes and using mouthwash. This has been a recurrent problem on and off for the last two years. Within three days of using my new ionic brush all the inflammation has gone. Eileen, London
