The Best Cheap Water Flossers of 2019

It's hard to say whether a water flosser is better than traditional string floss.

Most of the clinical studies that I've found have ties back to the manufacturer of a single product. As you might imagine, these studies conclude:

A.) The product is awesome; and

B.) The product is more effective than its competitors.

I ignored those studies. Unfortunately, the other studies that examine the effectiveness of "oral irrigators" have weakly-worded conclusions like "could be useful." 

My two cents: Ask your dentist if he or she recommends a water flosser for removing plaque or maintaining gingival health. If so, here are the best-reviewed water flossers that have sold for $50 or less in the past year:

Good Price: $43 | Great Deal: $38

This rechargeable, waterproof flosser is effective and conveniently-sized, according to several Amazon customers. Many customers accidentally pressed the "on" button at least once; others say the water pressure is too strong for their gums. Some reviewers say the reservoir must be filled twice per session.

Good Price: $39 | Great Deal: $26

This cordless water flosser is strong, portable and easy to use, according to several Amazon customers. Some reviewers were inconvenienced by this unit's USB-style charging port. A few say this unit gets slippery while wet; others say that it’s easy to turn the flosser on by accident.

Good Price: $36 | Great Deal: $28

Panasonic's battery-powered water flosser works well and travels easily, according to several Amazon customers. Some reviewers needed time to get the hang of it; others never quite did and say the unit is hard to clean. A few customers caution that this flosser doesn't last much longer than its two-year warranty.

Good Price: $37 | Great Deal: $35

This water flosser is portable, effective and comes with convenient tips, according to several Amazon customers. Some reviewers suggest using the flosser in the shower to avoid splashing. A few say this unit is awkward to use; others returned the flosser after discovering that it can only be charged via USB cable.
