What toothpaste for a sonic toothbrush?

In theory, any toothpaste should work well with a sonic toothbrush. But only in theory. Sonic toothbrushes clean your teeth in a slightly different way than conventional manual toothbrushes. First of all, they clean your teeth much faster. This is due to the fact that they remove deposits from the enamel much more effectively, but also that their movements, combined with abrasive substances from some toothpastes, can be quite invasive to teeth and gums. So, what qualities should the ideal toothpaste for a sonic toothbrush have? How do I choose the most appropriate product?

Why should sonic toothbrush users brush with special toothpastes?

Usually, people who switch from a manual toothbrush to a sonic toothbrush behave in one of two ways: either they don’t change anything in their everyday oral hygiene (after all, a toothbrush is a toothbrush, isn’t it?) or, on the contrary, they start wondering whether they can clean their teeth with the new type of toothbrush in the same manner and with the same accessories as before. The most questionable issue is toothpaste: is it enough to use a traditional toothbrush or do you have to buy a special toothpaste for your sonic toothbrush?

To answer this question, you need to compare how a manual and a sonic toothbrush work. The sonic toothbrush works much faster: it makes up to 96,000 vibrations per minute (even an efficient user can’t make more than 200 movements in the same amount of time with a manual toothbrush). As a result, when brushing our teeth with a sonic toothbrush we are able to remove many times more bacteria and harmful plaque from our mouth than when brushing with a manual toothbrush.

However, there are two sides to every coin. Toothpastes with strong abrasive properties (over 70 RDA) combined with sonic vibration may weaken the enamel structure and have a negative impact on gum health. That’s why everyone with a sonic toothbrush should choose their toothpaste wisely.

What should a sonic toothbrush toothpaste have in common?

Some toothpastes are too abrasive, which is not the only problem. Toothpastes that foam intensively or are thin in consistency are also unsuitable for sonic toothbrushes. The former combined with extremely fast movements of a sonic toothbrush result in too much foam accumulating in our mouth during brushing, which significantly reduces the comfort of brushing. On the other hand, toothpastes of too thin consistency tend to flow down from the bristle of the toothbrush and thus reduce the quality of washing.

A decent toothpaste for your sonic toothbrush, one that will allow you to brush your teeth safely, effectively and comfortably, should therefore be characterized by:

  • low abrasiveness coefficient – it is determined by the RDA (Radioactive Dentin Abrasion) of the toothpaste. The higher the value of this index, the higher abrasive properties of a given toothpaste. It is assumed that toothpastes for sonic toothbrushes should not have an abrasiveness coefficient higher than 70 RDA;
  • mild foaming agents in the composition – foaming agents are added to toothpastes to make them easier to spread in the mouth, and thus easier to remove plaque. However, a large number of foaming agents combined with the fast movements of a sonic toothbrush may cause too much foam to form in your mouth during brushing, which can affect your cleaning comfort. A decent toothpaste for a sonic toothbrush should replace in its composition intensely active SLS (sodium lauryl sulfate) with a much milder sarcosyl or cocamidopropyl betaine;
  • a gel consistency – toothpastes with a thin consistency easily run off the brush bristles during washing. Therefore, the solution is to invest in a product which will have a thick or, preferably, gel consistency (without granules). An additional advantage of this type of preparations is that they distribute active substances in the oral cavity even better.


What ingredients should be in a sonic toothbrush toothpaste?

Low abrasive qualities, mild foaming agents and a gel-like consistency aren’t enough. If you want to clean your teeth as effectively as possible and get the full potential out of your sonic toothbrush, you should take a closer look at the composition of the product you’re considering. The ingredients listed below guarantee that regular and conscientious use of the product will provide you with perfect protection against tooth decay and hypersensitivity, improve the condition of your gums, make your teeth whiter and your breath healthier.

A high-quality toothpaste for a sonic toothbrush should not lack:

  • hydroxyapatite – an element that rebuilds enamel and also smooths the surface of teeth, preventing bacteria from settling on them again. Moreover, it protects the dentine against the attacks of external stimuli, it brightens teeth and helps in the fight against hypersensitivity;
  • xylitol – a natural sugar, which perfectly helps fight cavities, as well as combats bad breath. It perfectly replaces the controversial fluoride in the toothpaste composition;
  • zinc citrate – works very well in the fight against bad breath. It binds volatile sulfur compounds responsible for unpleasant odors, effectively neutralizing them;
  • natural enzymes – the ones you should especially pay attention to are bromelain and papain. Both perfectly inhibit the formation of plaque, dissolve the stain-forming protein membrane, and also show anti-inflammatory and soothing effects.

“Sonic friendly” toothpastes dedicated to sonic toothbrushes

As you can see, there are a number of elements that determine whether a toothpaste works well with a sonic toothbrush, and it’s not easy to choose the right product. We can recommend the so-called “sonic friendly” toothpastes to anyone who has problems with this.

These toothpastes are specially formulated for sonic toothbrush users. Such toothpastes have all the features that distinguish top quality products for sonic devices – they have a low abrasiveness factor, appropriate consistency and valuable composition. You don’t have to worry about their cost either – prices of “sonic friendly” toothpastes are similar to those of all other toothpastes for everyday brushing available on the market.
