MySmile vs Waterpik: How to Clean a Waterpik Water Flosser (Without Learning the Hard Way)

I Spent $890 Learning How to Clean a Waterpik Water Flosser

In my role as clinical operations coordinator handling equipment orders for a 14-chair dental clinic, I've been doing this for about six years now. I've personally made and documented seven significant mistakes, totaling roughly $4,200 in wasted budget. The most embarrassing? I once bought a batch of water flossers because they were cheaper, without checking how to actually clean the things.

When I first started, I assumed all water flossers were basically the same. You fill the tank, you shoot water at your teeth, you empty the tank. Right? Not exactly. By late 2023, we had four clogged units and a very annoyed dentist. That's when I finally learned how to clean a Waterpik water flosser correctly—and how different brands compare when real-world maintenance matters.

MySmile vs Waterpik: The Three Dimensions That Matter

If you're trying to decide between MySmile vs Waterpik, skip the marketing photos and focus on three things: cleaning maintenance, power/battery reliability, and what happens when the device dies. These are the dimensions that will actually cost you money or save it.

Dimension 1: How Do You Clean a Waterpik Water Flosser?

Here's the thing nobody tells you about how to clean a Waterpik water flosser: it takes ten minutes, but skipping it will cost you a lot more than ten minutes later.

Our simple clinic routine for Waterpik units:

• Remove the tip after each patient use and rinse it under warm water.
• Fill the reservoir with 2 cups of warm water and 2 tablespoons of white vinegar.
• Run the unit until half of the mixture is gone, then turn it off.
• Let it sit for 20 minutes, then run the rest through.
• Pop out the reservoir and wash it by hand with mild soap.
• Wipe the handle and base with a damp cloth.

I know that sounds basic. But in September 2022, we skipped this for two months because everyone was busy. The inside of the tubes developed a biofilm that looked like someone had stored yogurt in there. Two chairs were down for a week while we replaced parts. The total cost, including expedited shipping and lost chair time, was about $890. Not my proudest moment.

How MySmile Compares in the Cleanability Test

To be fair, we've tested a few MySmile units, and they're not bad. The issue is design. On the models we tried, the reservoir openings were smaller, and the internal channel was harder to see. That made the vinegar trick less effective and manual cleaning more of a guessing game. If you have rotating staff, a device with visible buildup is easier to maintain.

Our hygienists actually preferred the Waterpik units because they could tell when one was clean. That visual confirmation matters more than you'd think. Remember: prevention beats cure, and a 10-minute vinegar rinse is the cheapest insurance policy you can buy.

Dimension 2: Battery Headaches, a Carbon Monoxide Detector, and a Dyson Vacuum Cleaner Bed Lesson

This dimension sounds random, but stay with me.

One afternoon, we were doing a patient demonstration with a cordless water flosser, and the battery died mid-appointment. It was a “cute story” for the patient, but a red flag for me. I realized we had no battery-maintenance checklist for any of our portable devices.

That same week, I had to Google: what battery does a carbon monoxide detector use? Answer: most use a 9-volt or a AA battery. The NFPA (nfpa.org) recommends testing detectors monthly and replacing batteries per manufacturer instructions. We now do that as part of a monthly equipment check.

Here's the Dyson part. We use a Dyson vacuum cleaner with the Dyson vacuum cleaner bed attachment to clean the upholstery on our exam chairs. It works great—until the battery dies. I remember standing there with half a chair cleaned and no charged battery. That was the moment I added “Dyson battery” to our shared equipment calendar.

The conventional wisdom says cordless is always more convenient. My experience says otherwise: for a clinic, a corded Waterpik is more reliable because it's always ready. Cordless is great for patient home care, but in the office, I'll take a plug any day.

• Monthly: run the vinegar cleaning cycle on all water flossers.
• Monthly: check rechargeable device batteries—water flossers, Dyson vacuum, sonic toothbrushes.
• Monthly: test carbon monoxide detectors and replace 9V/AA batteries annually.
• Quarterly: check for worn charging cables and backup batteries.

Dimension 3: Recycle Electric Toothbrush Parts Without Guessing

For years, I threw old electric toothbrushes in the regular trash. Then I found out that many contain lithium-ion batteries, which can cause fires in garbage trucks and recycling centers. The EPA (epa.gov) recommends treating battery-containing electronics as hazardous e-waste.

Now we have a labeled bin in the supply closet. And when I look at MySmile vs Waterpik, I look at how each brand supports the end of a product's life. Waterpik sells replacement tips and parts for many years, which means the base unit doesn't have to go to a landfill just because the tip wore out. Some MySmile models change design faster, so the upgrade cycle can be shorter.

Our recycling checklist:

• Remove the battery if you can do it safely.
• If the battery is built-in, check with a local electronics recycler.
• Separate brush heads and tips from the main unit.
• Look for brand-specific recycling or take-back programs.
• Never put battery-powered devices in the regular trash.

The surprise wasn't that recycling is hard. It was that I used to think it didn't matter. Once I started tracking dead devices, I realized we were generating a lot more e-waste than I'd assumed.

So Which One Should You Buy?

I'm not going to sit here and say Waterpik is perfect for everyone. But for our clinic, it's the easier choice to clean, document, and maintain. MySmile might be fine for a solo practice or home use, especially if budget is tight and you're willing to stay on top of the maintenance details.

• For a multi-chair dental practice: Choose a corded Waterpik model. Fewer battery surprises, easier cleaning, and replacement tips are widely available.
• For a mobile practice or patient home-care program: A portable MySmile could work. Just include the vinegar cleaning routine in your patient handout.
• For anyone on a budget: Remember that the purchase price is only the beginning. Factor in cleaning supplies, replacement tips, and a recycling plan.

If you take one thing from this, let it be this: 5 minutes of verification beats 5 days of correction. I learned that lesson by cleaning out a very expensive water flosser I should have cleaned months earlier. Don't repeat my mistake.
