## Description

desertcart.com: COSLUS ADA Accepted C20 Water Dental Flosser Teeth Pick, 300ML Larger Tank | Portable Rechargeable Oral Irrigator for Orthodontic & Sensitive Gums, Cordless for Travel, Family, Professional Set, Black : Health & Household

Review: I love it - I’ve used this everyday since I got it (it’s been almost 2 months) and I have yet to charge it. It works amazing and makes your mouth feel so clean afterwards. 10/10 recommend.
Review: This is a good, inexpensive water flosser - So far I really like it! I’ve had more expensive brands but keep knocking them off my sink so wanted to see if I could find a less expensive brand. I’ve had it for a few weeks and really like the way it works. The flosser settings are good, and I actually like the strength of the spray and am using the highest setting. I’m still finding the right setting for the back of the teeth, because the highest settings are too intense when the spray touches my tongue; but it still does the job on the lowest setting.

### ⭐⭐⭐⭐⭐ I love it
*by C***T on August 19, 2026*

### ⭐⭐⭐⭐⭐ This is a good, inexpensive water flosser
*by M***E on August 2, 2026*

So far I really like it! I’ve had more expensive brands but keep knocking them off my sink so wanted to see if I could find a less expensive brand. I’ve had it for a few weeks and really like the way it works. The flosser settings are good, and I actually like the strength of the spray and am using the highest setting.

### ⭐⭐⭐⭐⭐ Was definitely skeptical at first.
*by D***W on May 7, 2026*

Honestly I always thought these things were a gimmick. Kept seeing them pop up and never gave them a second look. Then my dentist handed me a coupon for one and I figured why not, worst case I'm out a few bucks. Glad I tried it. Hard to explain but it genuinely feels more thorough than regular flossing. I don't know the science behind it and it could just be placebo, but my mouth feels noticeably cleaner after using it. Been doing it every night before I brush and it's become part of the routine without much effort. The fact that it's cordless and rechargeable makes it easy to keep on the bathroom counter without a bunch of wires in the way. The 300ml tank is big enough that you're not constantly refilling it mid-use. It's a bit noisy, but you're only using it a few minutes at a time, so it really shouldn't bother anyone. Especially with a door closed. It's probably small enough to throw in a travel bag for a trip, but it's not exactly what I'd call portable. There was a little bleeding at first, but is apparently pretty normal early on. Not enough blood to worry about your gum health or anything, but don't be surprised if you see some blood. The highest speed/power might be a little intense for someone who's never done it before, so start with the child/massage first and move up once it starts feeling normal. If you're on the fence or rolling your eyes at these like I was, just give it a shot. It might surprise you.
