My dentist has been pushing me to water floss more consistently due to a wisdom tooth issue and this cordless model makes it so easy to use daily, the battery lasts 2 weeks Pros - The 300ML tank is a huge plus, I don't have to refill it as often as my old model. Gets me through a full mouth cleaning easily. - Adjustable water pressure is excellent. I started on low for my sensitive gums and can now dial it up to medium without any discomfort. The pressure levels actually make a difference. - Battery lasts forever. I charge it every few weeks with regular daily use, which is way better than I expected for a cordless device. - Super portable and lightweight. I bring it on work trips in my carry-on with zero issues. - Quiet operation, doesn't sound like a mini jet engine like some other brands I've tried. - Price point is unbeatable compared to similar products. Felt like I was getting premium features without breaking the bank. Cons - The tip replacements are a bit pricey if you need extras, though they do seem to last a while. - I had an issue while replacing tip with the replacement part breaking and staying inside but i was able to get it out. Highly recommended! Review: Wish I would have bought this earlier - My Dentist had been suggesting I get a Water Pik for several years now. After getting a dental implant in the last tooth and having trouble with food getting impacted I decided I needed to do something. Regular floss was not working well. I finally saw this one on special and went ahead and took a chance on an off brand due to the lower cost. I’m perfectly satisfied with this one. In fact I rarely flossed with the old waxed dental floss string, but am now flossing 2x a day because it feels so good. It comes with several different tips that are easily changed out. I started with the lower pressure setting for a couple of months to get used to it. I’ve now progressed to the medium setting and doing well. I’ve been amazed at how much debris it gets out of my teeth. Even after brushing, though I recommend to use the water flossed before brushing. I charged the battery once in June when I first received the flosser. It’s now September and still going strong so the battery lasts a long time on one charge. I fill the tank with water and am typically done after only 3/4 of a tank. I just keep going until the tank is empty because it feels so good on my gums. I highly recommend this water flosser. If you have one or more implants definitely get one and you will be very happy. I will say it takes a little practice to remember to shut it off before you take it out of your mouth. My wife laughed at me the first few times I used it but she said the bonus was I had to clean the bathroom. 😂 ## Features - Advanced Water Pulse Technology — Gentle Enough for Sensitive Gums: Delivers 1,500–2,000 pulses per minute across 4 adjustable pressure modes (50–150 PSI). Start at the lowest setting to gently flush food debris from inflamed or bleeding gums, then increase pressure as comfort improves. It helps remove food debris and reduce buildup from hard-to-reach areas compared to brushing alone—ideal for anyone whose gums bleed with traditional string floss. - Rechargeable Cordless Design — 30 Days on One Charge: A single 3-hour USB charge provides approximately 30 days of daily use (one 2-minute session/day). No proprietary adapter needed—charges from any 5V USB port, laptop, or power bank. Compact enough to fit in a standard toiletry bag for business trips, vacations, or college dorms. - BPA-Free 300ML Water Tank — One Fill, One Complete Clean: The 300ML capacity delivers a full 60-second cleaning cycle without stopping to refill. BPA-free food-grade material ensures no chemical leaching into your water. Detachable tank design makes filling and rinsing fast and hygienic. - Designed for Orthodontic & Dental Work: Reaches behind archwires, around brackets, under bridges, and along crown margins where string floss and interdental brushes cannot go. Includes 5 specialized jet tips (standard, orthodontic, periodontal pocket, tongue cleaner, and nasal) so each family member can have their own color-coded nozzle. Replace tips every 3 months for optimal hygiene. - IPX7 Fully Waterproof — Shower-Safe & Easy to Clean: Rated IPX7, meaning the entire unit can be submerged in up to 1 meter of water for 30 minutes. Use it in the shower as part of your morning routine without worrying about water damage. Rinse the whole device under the tap after each use for hassle-free maintenance. - Easy Charging & Maintenance (Adapter Not Included): Charges via standard 5V USB power. Adapter not included, but compatible with any existing 5V charger. For optimal hygiene and performance, replace the nozzle every 3 months. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D5RFBB7M | | Additional Features | Portable | | Best Sellers Rank | #2,737 in Health & Household ( See Top 100 in Health & Household ) #8 in Power Dental Flossers | | Brand | Onlyone | | Brand Name | Onlyone | | Color | Black | | Customer Reviews | 4.4 out of 5 stars 9,309 Reviews | | Included Components | 1 Charging Cable, 1 User Manual, 5 Replacement Heads, Adapter not included, Water Dental Flosser | | Item Dimensions | 8.68 x 2.91 x 3.19 inches | | Item Nype Name | Water Dental Flosser | | Manufacturer | Onlyone | | Manufacturer Part Number | FC5360 Black | | Manufacturer Warranty Description | 1 year | | Material Type | Plastic | | Model Name | Onlyone FC5090 | | Model Number | FC5090 | | Power Source | Battery Powered | | Product Benefits | Freshen your Breath, Removes Plaque, Improve Oral Health,smile with Confidence | | Recommended Uses For Product | Daily Cleaning | | Special Feature | Portable | | Tank Volume | 300 ml | | Target Use Body Part | Teeth | | UPC | 198715558647 | | Unit Count | 1 Count | ## Product Details - **Brand:** Onlyone - **Power Source:** Battery Powered - **Product Benefits:** Freshen your Breath, Removes Plaque, Improve Oral Health,smile with Confidence - **Unit Count:** 1 Count ## Images ![Onlyone Water Flosser with Adjustable Water Pressure for Daily Oral Care - Image 1](https://m.media-amazon.com/images/I/61+2dpyMNBL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Why does the Onlyone water dental flosser have 4 modes?** A: Designed with four simple modes, this water flosser provides easy operation for adults, seniors, and teens.

Helps get the food particles out of my month. This thing holds a very long charge. I bought it in May and I haven't charged it since. It does what it is suppose to do. I love it. It is very powerful, and sturdy. I live that i can change the heads and the settings are perfect. I do prefer the high setting for ny flossing needs. ## Frequently Bought Together - Onlyone Water Dental Flosser, 300ML Portable Oral Irrigator for Teeth, 4 Modes and 5 Jet Tips,Rechargeable Irrigation Cleaner,Electric Flossing Machine Power Flossers & Irrigator Accessories Black - MasterMedi Tongue Scraper for Adults with Multicolor Travel Cases (2 Pack), 100% Stainless Steel, Reduce Bad Breath, Tongue Scrubber, Easy to Use, Tongue Cleaner for Oral Care & Hygiene - Aquasonic Black Series Ultra Whitening Toothbrush – ADA Accepted Electric Toothbrush- 8 Brush Heads & Travel Case – 40,000 VPM Electric Motor & Wireless Charging - 4 Modes w Smart Timer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/637239495-onlyone-water-flosser-with-adjustable-water-pressure-for-daily-oral](https://www.desertcart.jp/products/637239495-onlyone-water-flosser-with-adjustable-water-pressure-for-daily-oral) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-22*
