Bitvae Smart Oral Care

Competition in the $3 billion electric toothbrush market is fierce and as a result, manufacturers are having to work hard to catch the attention of potential buyers. Standing out from the crowd is difficult, but Bitvae has done just that with the release of their new S2 Smart toothbrush.

Bitvae provides customers with smart oral care products that allow them to confidently monitor and improve their routine and that of their family, the Bitvae S2 electric toothbrush is a full-featured eclectic toothbrush that includes all of the advanced technology that consumers are becoming accustomed to.

Bitvae is a new manufacturer that we were unfamiliar with, but their S2 smart toothbrush and the companion iSpruz app demonstrate their commitment to producing high-quality oral health products. I have tested many electric toothbrushes over the years but Bitvae has managed to surprise me with some of its thoughtful innovations and ideas.

My initial impression of the product was good. The packaging was well designed with each component being safely packed.

Bitvae S2 cleaning heads

The toothbrush comes with eight cleaning heads in total which is very generous compared to other manufacturers. Oral B and Sonicare for instance typically ship with only one or two cleaning heads so a quantity of eight replacements would last me two years if I followed the dentist’s advice and changed the head every 3 months.

The first pleasant surprise was that the S2 comes with a choice of cleaning heads.

  • 4 x Deep Clean Brush Heads
  • 2 x Soft bristle cleaning heads
  • 2 x Charcoal bristle cleaning heads

There are a number of evidence-based reasons for selecting your cleaning head carefully.

Deep Clean

Research has shown that harder toothbrush bristles are better at reducing plaque.

Very hard bristles can never be recommended because they can damage tooth structure but a good medium bristle is a good choice for people who tend to accumulate large amounts of plaque.

Whitening Charcoal

Although charcoal is often associated with teeth whitening, there is no reliable evidence to suggest that a charcoal bristle cleaning head will change the color of teeth.

However, there is research to suggest that charcoal-infused bristles can help to inhibit bacterial build-up

Sensitive Care

Soft bristle toothbrush heads are ideal for people with sensitive teeth or gum recession.

The Sensitive Care cleaning heads also have a tongue cleaner feature on the reverse side.

Bitvae iSpruz App

The capabilities of the S2 toothbrush can be further enhanced by pairing it with the iSpruz app.

The app is available for both IOS and Android and is free to download from the Apple App store and Google play. Getting started with the iSpruz app was super easy and it took me less than five minutes to download it onto my iPhone, create an account, pair it to the toothbrush and start my first smart toothbrushing session.

The sole objective of brushing your teeth is to remove as much plaque as possible. And anything you can do to improve your brushing technique will improve your oral and general health. Unfortunately, many people don’t realize just how poor their brushing performance is. Most of us to a great job of cleaning the easy to get to surfaces but often neglect the more awkward areas.

By brushing along with the iSpruz app, you will train yourself to brush each tooth surface in an organized and consistent manner and avoid leaving plaque in the problem areas. If you constantly miss a particular spot when brushing your teeth, the accumulated plaque will quickly turn into tartar and eventually lead to tooth decay and gum disease.

The app has lots of cool features but for me, the main benefit of using it is to train yourself to bring the toothbrush bristles into contact with every single tooth surface.

Bitvae S2 battery

The Bitvae S2 has a built-in rechargeable battery. A rechargeable battery can be charged and discharged many times over the course of its life span and is generally regarded as being much more environmentally friendly than disposable batteries.

According to Britvae’s laboratory tests, the S2 can hold a charge for up to 100 days which represents excellent battery performance compared to some other brands. In theory, this would mean that you would only have to charge the toothbrush four times a year at most. I have only been using this particular toothbrush for a week so it is too early to verify its superior capabilities, but I will be interested to see how many days of use I can get.

Charging the Bitvae S2 toothbrush

The Bitvae S2 come with a USB 2.0 charging cable which gives you plenty of charging options. You can change from a USB mains plug, computer or USB power bank.

Bitvae S2 cleaning modes

As with many electric toothbrushes, the Bitvae S2 comes with a number of different cleaning modes –

  • White – This is the most intense cleaning action and the selection that is likely to remove the most plaque and teeth stains. This mode is suitable for people who are already accustomed to using a high-powered toothbrush and don’t have sensitive teeth or gum recession.
  • Clean – This is a more moderate cleaning motion that would be suitable for the majority of users.
  • Soft – Never used a sonic toothbrush before? The soft cleaning mode would be a good choice to get started. Sonic electric toothbrushes can be quite jarring for first-time users so choosing a gentle motion can help acclimatize to the sensation.
  • Gum care – This mode creates a different motion by varying the intensity of the movement. The gum care selection is good for cleaning along the gum line to stimulate blood flow in the periodontal tissue.
  • Smart – This mode gives you the ability to create a custom cleaning program that is tailored to your own needs. By connecting to the iSpruz app, you can set the cleaning mode, brushing power and brushing time for both the morning and evening brushing sessions.

S2 Pressure sensor

Brushing teeth with too much force can wear away the delicate gum tissue that surrounds the teeth. This is particularly damaging because gums won’t grow back. It is not uncommon for people to brush their teeth too aggressively without realizing the damage that it can cause. Research has shown that 150 grams is the maximum force that should be applied to the teeth and gums and any pressure over and above that can be detrimental to tooth structure.

To help avoid this, Bitvae has incorporated a warning light system to alert the user if they are brushing with too much force.


The Bitvae S2 is an excellent toothbrush that has everything yo need to improve and maintain your oral health.

Giving the users a choice of soft, medium, and charcoal bristles straight out of the box gives this product a competitive edge over many other brands. Manufacturers like Sonicare and Oral B charge a premium price for replacement cleaning heads so getting eight heads as standard with the S2 is much appreciated.

The five cleaning modes make this toothbrush suitable for everybody regardless of their level of oral health. I particularly liked the smart mode because it let me increase my timed sessions to 3 minutes rather than the normal two.

I found the iSpruz app to be very easy to use. It seamlessly connects to the toothbrush and I was able to intuitively discover all the functionality without the tiresome need to consult a user manual. Although toothbrush apps are often written off as being gimmicks, I genuinely believe they can legitimately help some people improve their oral health.

If the Bitvae claims are true, then the 100 day battery life is also a huge plus point.

Given the low price point of this toothbrush, I have nothing bad to say about it at all. Britvae has not compromised in quality and performance to deliver a competitive product.

Overall the Bitvae S2 toothbrush is impressive on many levels and I highly recommend it.
