What Is THE FAIRYWILL 5020E Water Flosser?

Water flossers are a popular oral hygiene accessory that many people favor over traditional flossing with a string. They also tend to be quite expensive, and the high price point can leave people wondering if they are worth the cost. Fairywill manufactures a water flosser that will not break the bank. Their 5020E Water Flosser is available on Amazon for just $33.99. In this review, I will cover the important things you need to know about water flossers in general and the Fairywill 5020E in particular.

A cordless water flosser is a handheld, powered device that emits pressurized water for the purpose of removing dental plaque from the teeth. If you have ever taken your vehicle through a touchless car wash, you understand the concept of power washing to remove debris and leave a clean surface. You probably also understand that pressurized water does not remove all buildup or debris present on your vehicle.

The same is true for a water flosser. No one should use it as his or her sole oral hygiene instrument. It does not take the place of brushing your teeth with a good, plaque-removing technique. It can be a beneficial accessory to brushing.

It is important to understand that there is no magic wand dental tool that will work effectively for every person. So you will notice a generous usage of the word “can” in this review. It is possible that a water flosser can effectively remove dental plaque from some surfaces of the teeth in some patients.

  • A water flosser can remove dental plaque from areas between the teeth and near the gums.
  • A water flosser can reduce gingivitis (inflammation of the gums) caused by the buildup of dental plaque.
  • Patients who suffer from periodontal disease (progressive gum disease) can successfully maintain gum health by adding the use of a water flosser.
  • Water flossers can be used to remove dental plaque around dental implant restorations, cemented bridges, and orthodontic appliances.

I do not use the word “will”, as in “A water flosser will remove dental plaque…”, because of the endless possible combinations of the various factors that impact plaque removal. A few of these factors are tooth and gum positioning, plaque consistency, the presence of dental appliances or restorations, and a person’s manual dexterity.

The Fairywill 5020E Water Flosser

The Fairywill 5020E water flosser is a rechargeable single handheld unit with an attached water reservoir. This reservoir holds 300mL of water and is simple to fill and empty. The 5020E has three different modes: clean, soft, and massage. The modes differ in their pressure setting and frequency of pulses. The clean mode uses a higher pressure with more pulses per minute (90psi, 1800 pulses per minute), and the soft mode uses a lower pressure with fewer pulses per minute (40psi, 1400 pulses per minute). The massage mode alternates between these two settings.

My Experience with the Fairywill 5020E Water Flosser

You have to understand that I am a dentist, and my oral hygiene routine is already pretty strict. I never miss a single night of flossing with Cocofloss dental floss or brushing with my favorite electric toothbrush, soI wondered if I would notice any improvement at all by adding a water flosser. However, after After using the Fairywill water flosser consistently, I found it to be a useful addition to my oral hygiene routine.

It took me a few tries before I was comfortable with the size of the large base, which contains the water reservoir, and the sheer volume of water it emits. It was quite simple to use, and after the initial learning phase, it was less messy. I found that the easiest place to use it is in the shower!

I have several areas of gum recession and black triangles between the teeth, which are common sites of food impaction. Because the teeth in these areas are sensitive, I made sure to use lukewarm water instead of cold, and I used the “soft” setting. This pressure was sufficient to remove food debris and presumably some dental plaque as well.

I did take particular notice of the fact that there was less debris on my floss when I used the water flosser first. That tells me that the water flosser was effectively removing at least some degree of food and plaque buildup from my teeth.

Who Should Use a Fairywill Water Flosser?

Compared to other Waterflossers on the market, the Fairywill 5020E is very competitively priced and I consider it to be a smart investment in oral hygiene. By removing plaque and flushing out any gum pocketing, it will help people maintain healthy gums and reduce the risk for periodontal disease and cavities. I would recommend a Fairywill water flosser to anyone who either has a barrier to traditional flossing (like orthodontics, dental bridges, problems manipulating the floss, etc…) or who simply refuses to floss regularly. Compliance is a big problem with flossing, so a person who would be more willing to use a water flosser than traditional floss should absolutely do so.

Because the wires associated with traditional braces and the connection between the teeth in a dental bridge prevent someone from being able to floss in the traditional method, a water flosser is a wonderful tool. It is much easier to use than the accessories required to reach dental floss underneath these appliances. The people who have these types of appliances tend to fall into the category of those who do not have the greatest ability of cleaning underneath them. (Patients with braces are often children, and patients with bridges are often senior citizens.)

Patients with dental implant restorations often have large gaps between the dental crown and the gums, allowing clumps of plaque to accumulate. This is another great application for a water flosser.

Water Flossers vs. Traditional Floss

There are some scientific studies aimed at comparing the effectiveness of water flossers with traditional flossing. The problem is that the companies that manufacture water flossers funded most of these studies. Water flossers are not new. The first oral irrigator appeared in 1962. But there is still insufficient evidence to make a solid claim that a water flosser is a better tool for plaque removal than traditional string floss.

The studies that we do have show conflicting information. Some state that the water flosser removes as much dental plaque as string floss. Others show that it does not physically remove plaque, but it does damage the bacteria in the plaque. This would account for improvements seen in gingival health.

RESEARCH

US Army Institute of Dental Research, Walter Reed Army Medical Center, Washington DC

JOHN M. BRADY, WALTER A. GRAY, and SURINDAR N. BHASKAR

This study conducted at the Walter Reed Army Medical Center showed that oral plaque biofilm is susceptible to changes in fluid dynamics characterized by powered water flossers. Bacterial plaque is perfectly equipped to survive and flourish in the fluid of the mouth but it is not designed to cope with the rapid changes of force, direction, and pressure exhibited by the water expelled by a water flosser like the Fairywell oral irrigator.
In the experiment, a pulsating water stream was applied to the dental plaque at a pressure of 70 psi. When viewed under an electron microscope, it was clear that the characteristics of the biofilm had changed dramatically.

Images obtained from the electron microscope clearly show that the number and physical condition of the organisms has been significantly altered by the jet of pulsed water. In many cases, the cell walls have been damaged, or if the structure is intact, the actual contents of the cell have been sucked out completely. The resulting reduction in functioning microorganisms means that there will be fewer toxic by-products produced to attack teeth and infect gums.

Recommendations

While more research is necessary to get definitive answers backed by science, I think it is safe to make several assumptions about the effectiveness of water flossers.

  • A water flosser is more effective than NOT flossing. Adding a water flosser to one’s oral hygiene routine will remove more dental plaque and promote good gingival health, especially if that person does not floss.
  • A water flosser is more effective than flossing the wrong way. Many people use an improper technique when flossing, which does not effectively remove dental plaque from the sides of teeth.
  • A water flosser is a valuable tool for cleaning underneath dental appliances, like braces, bridges, and implant restorations. By flushing areas prone to accumulation of plaque and food debris, the water flosser will help patients with these dental appliances maintain better gum health.
  • A water flosser is an effective added tool for oral hygiene. It is not a replacement for brushing.
