How Does The Fairywill Sonic Toothbrush Work?

Fairywill Electric toothbrush 1

The Fairywill D7 Sonic Electric Toothbrush provides a lot of features at a fraction of the cost of other brands. 

Here’s what it comes with:

  • Five cleaning modes (White, Clean, Sensitive, Polish, and Massage)
  • Two-minute timer to encourage optimal brushing 
  • Thirty-second interval pacer to remind you to cover each quadrant of your mouth
  • The American Dental Association’s (ADA) Seal of Acceptance
  • Four brush heads with purchase
  • Thirty-day battery life
  • Lifetime customer support
  • Two-year warranty

It’s also remarkably light — just 2.7 ounces when a brush head is attached. At just $30, it’s difficult to find a toothbrush that provides as much value for the money. 

The key to understanding how the Fairywill D7 works is that it’s a sonic toothbrush. This means it cleans much faster than a regular electric or manual brush. 

The way to measure this is in brush strokes per minute, or BPM.

Most regular electric toothbrushes clean between 2,500 and 7,500 BPM. By comparison, a manual toothbrush cleans at only 300 BPM. 

The Fairywill D7 cleans between 40,000 BPM. This is 5 to 16 times faster than electric toothbrushes and is even faster than some Sonicare toothbrushes.

Another feature differentiating sonic toothbrushes from regular electric toothbrushes is their use of fluid dynamics

Sonic toothbrush bristles vibrate at a high rate of speed, pushing toothpaste and water into the gaps between your teeth and gum line. This helps clean your mouth more thoroughly and protects against cavities and gingivitis.

The Fairywill D7 has the ADA  Seal of Acceptance, meaning it’s proven to remove plaque and prevent cavities. 

If you’re new to sonic toothbrushes and don’t want to spend a lot of money trying one, the Fairywill D7 is an excellent option.

Fairywill Sonic Toothbrush Features 

The Fairywill D7 has an impressive amount of features for its price point. Some, like the timer and pacer, are standard. 

These features help ensure you brush for the ADA-recommended 2 minutes and adequately cover all of your teeth. Those who use manual toothbrushes often fail to do this, leading to oral hygiene issues later on.

Other features are less common, with some adding more value than others. 

For example, while it offers 5 cleaning modes, most people will probably only find value in 2: Cleaning and Sensitive

Thankfully, the brush remembers what mode you last used it on, so there’s no need to cycle through all of them every time you turn it on.

In addition, while the brush overall has an attractive look, there’s a certain “cheap” feeling to the build quality. The brush handle lacks the “grippiness” found on other brushes. 

Here’s where the Fairywill toothbrush shines:

  • Weight — At 2.7 ounces, this is one of the lightest brushes out there. 
  • Battery Life — The Fairywill has 1 month of battery life on full charge, easily doubling many brushes that cost twice as much. 

On top of being an excellent budget option, these two aspects also make the Fairywill a good travel toothbrush.

What Customers Are Saying About the Fairywill Toothbrush

Most reviews for the Fairywill are positive. Many praise the customer service, long battery life, and overall value the brush provides. 

Negative reviews include how the brush’s plastic feels and some issues with it only lasting 6 to 12 months.

Is the Fairywill Electric Toothbrush Reliable?

Despite being a relatively new brand, Fairywill toothbrushes have gained a reputation for reliability. As a result, there aren’t any significant reports of the brush breaking for no apparent reason. 

All Fairywell toothbrushes have a 2-year warranty. In addition, Fairywill has received positive reviews for its customer service. If your brush breaks within the warranty window, the company will send you a replacement.

Other things in favor of the brush’s reliability include the long battery life and ADA Seal of Acceptance.

Price Summary & Where to Buy 

A Fairywill D7 kit comes with an electric toothbrush, 1 interdental toothbrush head, 3 standard brush heads, a travel case, and a charging cable. Replacement heads cost $12 for a pack of 4. The brush is available in black, pink, and white.

The company no longer sells through Amazon, so your best bet is to buy from their site directly. The brush currently costs $30.

Is the Fairywill Sonic Toothbrush Right for You? 

If you’re new to sonic toothbrushes, or electric toothbrushes in general, the Fairywill toothbrush is not a bad option. It provides many valuable features at an affordable price. 

If you’re a frequent traveler, you may also want to give the Fairywill D7 a look due to its lightweight and long battery life. 

On the other hand, the lack of a pressure sensor is something to consider if you have weak enamel. Additionally, those who prefer a more premium feel to their sonic toothbrushes may also want to look elsewhere.
