The RotaDent Electric Toothbrush – A Bias Review

Rotadent Electric ToothbrushOver the years I have had mixed emotions about the RotaDent electric toothbrush.  Overall it is one of my favorites, but I am not a fan of it as a solo brush.  Below is a list of features that the RotaDent has:

Rotadent Features

  • There is a LIFETIME warranty on the battery, as far as I am aware, they are the only toothbrush company that offers this.
  • The bristles are made of silk filaments vs. nylon bristles which are what most bristles are made from.  This is perfect for focusing on the gums where periodontal disease comes from, and for people who are concerned about receding gums or suffer from sensitive teeth.
  • It is the ONLY brush where the head rotates in a full 360*.  Although the other round style brushes appear to rotate, they simply oscillate back and forth.
  • There are multiple styles of heads which allow you to get deep into the in-between areas of the teeth and under bridges or implants.
  • Due to the pointed head, this style brush is perfect for reducing the stain and buildup which accumulate in-between the teeth or build up at the gum line.
  • Great for people in braces!  The pointed tip allows you to clean around the brackets and bands easily.
  • It is an extremely effective electric toothbrush in the fight of decay and gum disease.  When you begin using it you will notice a foam that is created even without toothpaste.  This is the bacteria being oxygenated.  You will notice this dissipate quickly with continued use, seeing as there is much less bacteria accumulating in your mouth.
  • 92% of the plaque is removed within 1 minute of use.
  • Bleeding gums and bad breath are greatly decreased when used properly.
  • The overall shape of the toothbrush is designed to mimic the polishing tool that is used to polish your teeth at the dentist.

To be fair, I have to give the “negatives”.  This is a list of some of the frustrations that both I and patients that I have seen over the years have stated.

  • It tickles like crazy!  Rest assured that within a few uses this gets better.  This happens because the brush is working in places that you have not gotten to before with the brush you are using.
  • It is difficult to brush your tongue with it, which is vitally important to a healthy mouth.  They supply a tongue scraper, or you can use a traditional brush.
  • It is very technique sensitive and takes time and patience to get used to it.
  • The old design left the bristles out in the open.  The new design has taken care of this issue by putting a cover over the head.
  • The other complaints that I have heard over the years were about the charger and the way it plugged in like a cell phone and lack of a timer.   The new Rota Dent Plus has taken care of this by changing the base of the brush and adding a 2 minute timer with multiple speeds on the brush.
  • Gel is recommended because paste is difficult to get out of the bristles.  You could also dip the head into a liquid such as Tooth and Gums Tonic and simply use the residual liquid to rinse with once you are finished.

Overall this has been a brush that I have recommended for nearly 20 years.  It has been a great benefit and lifesaver (or toothsaver) for many people.  Feel free to contact us for detailed instruction information on how to use this fantastic professional hygiene tool!

    The casing of the charger comes apart – we have two chargers and they both came apart. It is a safety hazard that should be fixed.

    There actually is not a lifetime warranty on the Classic. I just called to get mine replaced after 3 years use, and was told since they no longer make the Classic, they will replace it with the Contour and that only has a 4 year warranty. So the warranty on the original Classic was not good for my lifetime – only good until they stopped making that model.

      You are right Robin…I’m very sad that the company has made so many changes. This product is not what it used to me. I prefer the Revolation toothbrush now.

    Now they have gone back to the original charger design. My charger also came apart and rusted. It was awful. The new model has only a 2 year warranty.

    We have bought two and they lasted less than a year. Customer service was no help and it is a shame because this is the best toothbrush and I have recommended it to many. They should honor their product.

    Rotadent is A TERRIBLY made product with a GREAT Idea that other competitors do not offer.
    To my knowledge only Rotadent offers the pointed brush among other brushes. That is helpful
    with Gingivitis along the gum line. Rodatent ( all three generations) is very prone to breakage
    either the main unit suddenly dies or the interchangeable brushes do not function properly. Quiet
    often the brush loosens it self from the main unit in the middle of brushing only to be put back
    again and come off again. One would think that after 2 or more decades of manufacturing Rotadent
    will get it right but NOT So.
