Waterpik Wp-660: Is It The Best Waterpik On The Market?

The waterpik Wp-660 is being advertised as The Best Waterpik on the market. But before we even entertain this notion we need to look at it in critical detail and see whether it stands up to this statement.

Waterpiks are getting more popular by the day because of the apparent superiority they have over regular flossing. There have also been studies carried out highlighting this point in more detail.

Essentially the pressure of the water that is released from the tube disrupts the small particles and soft plaque from in between teeth and this keeps bacteria from settling down and forming biofilms.

Can regular flossing get the job done?


To be honest if your brushing and normal flossing is good then buying a waterpik is not an ideal investment but if your someone who has trouble using string floss and make your gums bleed as a result then it is worth looking into!

What Is The Waterpik Wp-660?

waterpik wp-660

It’s an electrically driven device that pumps water at high pressure in between your gums and teeth. It has a small tank to hold the water and different settings so you can choose the one that suits you best.

It’s been approved by the American Dental Association and as such has the seal of acceptance marked on it.

It’s relatively big so has to be set on a counter top close to a mains connection for it to work. It could be quite hazardous with all the water around so you will need to be extra careful while using it.

It’s also undergone clinical trials which has resulted in significant improvements in oral health, including a 93% improvement in reducing bleeding and up to 52% better at reducing gingivitis than traditional dental floss.

It’s currently the Number 1 seller as well as being Amazons choice and with over 13000 reviews there must be something right about it. Why not go and read what previous customers have been saying about it.

Who Is It For?

This model can be used by people who don’t  know how to floss effectively using regular string floss or people who suffer from gum disease. It’s been studied and has the potential to combat this problem if used as part of a good oral routine.

The only age range we would caution is children under 8 years old because the pressure from the nozzle might be too much for some and it could cause pain to the gums and make them sensitive. In saying that, the pressure can be adjusted to a level where it doesn’t cause discomfort but we reckon the more powerful settings will give the best results with this kind of flossing.

How To Use The Waterpik Wp-660 For Best Results

Follow these steps for maximum effect:

  1. Fill the water tank/reservoir with lukewarm water (tank can be lifted out and replaced).
  2. Fit the appropriate nozzle to the handle of the flosser ensuring it has clipped into place.
  3. Adjust the pressure dial on the unit to your desired pressure level (can be adjusted later).  If it’s your first time using, turn down to a lower setting.
  4. Press the power button to switch the unit on.
  5. Lean over the sink and place the tip of the flosser into your mouth. Close the lips enough to prevent splashing while still allowing water to flow from mouth into the sink.
  6. Slide the switch on the handle from off to on, the water will begin to flow.
  7. Aim water at the gum line at a 90 degree angle. Follow the gum line and pause briefly between teeth.
  8. When complete, slide the button to ‘off’ and then press the power button to turn it off.

Extra Little Tips On Using The Wp-660

  1. Put a wash cloth or grip pad under the unit to help lower the vibrations
  2. Once a month do a cleaning rinse: clean the basin out with vinegar, allowing it to soak for 1 hour and dont forget to put the wand tips in with it. this will kill all the odour causing germs. pour that out and do a full hot water rinse to remove the vinegar. afterwards do a hydrogen peroxide rinse, this will kill any mildew spores in the tubing
  3. Dont leave water in the basin, or put any non-liquid or sticky additives in. You dont want things clogging up the tubing.

Are there Any Negatives To The This Waterpik…

Well with every product there is always going to be Pros and cons. The Waterpik Wp-660 is no exception:


  1. On/Off button hard to switch. There have been some reviews by customers stating that the on/off button on the handle is hard to operate, however you also need keep in mind that these same people also have reported to have arthritis in their fingers. generally these people would have difficulty operating all similar oral irrigation devices not just the wp 660.
  2. Only compatible for use in North America
  3. Size. Its a little bulky, not ideal for the smallest bathrooms with limited work surface space.
  4. Messy. It can take some time to get used to the right technique and avoid making a mess but initially you are bound to get water squirting all around you.

What People Are Saying About The WP-660…

With over 13000 reviews on Amazon and currently holding the Number 1 Seller status as well Amazons choice you should feel confident about it. It has an average of 4.4 stars out of 5 which means the majority of people liked it.

Here is review left by Ebony: (March 2019)

“So… this Waterpik is amazing. By the way this is my first review ever on Amazon after ordering numerous of things. So I had 4mm and 5mm periodontal pockets from not flossing and also experienced some bone loss, I also had to get a very uncomfortable deep gum pocket cleaning. I literally hated flossing and would find myself avoiding to floss even though I needed it very much. My gums were red, swollen, and inflamed because I was in the early stages of periodontal disease. I started using the Waterpik flosser, and instantly like this way of flossing much better! After using it consecutively each night for only 5 days my gums were noticeably better and felt much better. After 2 weeks of using the Waterpik flossing, coconut oil pulling, and mouthwash treatment, my gums have done a complete 180 and my mouth and gums are starting to heal properly! Also this flosser can be somewhat loud, but definitely gets the job done ( but the dentist still recommends string flossing). Brought this with my own money and this is an honest testimonial/review. I will be back with an update on what mm my gum pockets will be!”

The only downside is the noise it makes. Sure it’s bearable but make sure you don’t use it whilst you have people sleeping otherwise they won’t be very happy with you!

Waterpik Wp 660 F.A.Q

Q. Is the Waterpik 660 available in Europe?

A. Currently the product is only available in North America

Q. Where to buy this particular model?

A. You can purchase the waterpik wp 660 directly from Amazon.

Q. Waterpik offers a 3 year warranty on this product, If i purchase through Amazon, is the warranty still valid?

A. Yes the warranty on the wp 660 will still be valid

Q. Can this be used with mouthwash in the reservoir?

A. We don’t see why not. Pure mouthwash might be too much for the mouth coming out at hard force and would also use quite a lot. We know someone who mixes half and half. Since some mouthwashes can be sticky, we would also run clear water through to clear the hose.

    I have actually been looking into purchasing a water pik because I have issues with trying to floss in the very back where my wisdom teeth once were. This is the best review, of any water pik, that I have came across. You have made my decision a lot easier. Are there any other attachments that I can purchase to go with this one?

    • oralb says:

      Hi dawn, thanks for the comment. Yeah i mean i find it quite hard to floss with regular strips. Like you i cant get to the back of my teeth and especially because my teeth aren’t aligned properly so it makes it extra awkward. The waterpik is really good because for me it makes it alot easier to floss. 

      Coming to your question, the flosser comes with 7 attachments each carrying out an individual function. In my opinion that is all you need to keep your teeth nice and clean. I mean if one of the attachment breaks you can order a replacement. 



  • Lyle says:

    Would you say this water flosser is more effective than regular flossing, or using a floss harp? I do this everyday about 2 times and I feel like my teeth and gums are healthy, I don’t usually get a lot of trouble at dentist.

    But if you think this product is then I might give it so consideration. My mum bought something similar to it and seems to like it.

    Although when I tired it, it was a little uncomfortable.

    • Teeth Man says:

      Hi Lyle

      I would say that once you get use to the waterpik water flosser and know how to use it, it is much more effective than regular flossing. For me personally i cant get to the back of the teeth with regular and harp flossers due to my teeth alignment. This product helps with that

      If you are flossing regularly and have healthy teeth then i dont really recommend you get the waterpik. Keep doing what works for you :). especially because you said it felt uncomfortable using the electric flosser, 

      Do you know the product your mum uses exactly?


  • Kehinde Segun says:

    This is amazing. I really loves how this waterpik works. I have never heard of this before, but reading this post has made me realised how cool this is. This waterpik is cool but what really scares me is the part that said it could be hazardious with all water around me. How can someone avoid the danger at 100% rate?

    • Teeth Man says:

      Hi Kehinde

      I don’t think there is any bathroom where the socket is directly next to the sink. This means you are safe as no water will be in contact with the socket and therefore no risk of electric shock.

  • affiliate_ghost says:

    hello :), this was such an in depth and amazing review to read and it answered every possible questions i had. I do not enjoy flossing as much as my gum usually feels sore. i have been searching for a viable alternative and this looks perfect. sure would give it a try and share this ost with friends. thanks

  • Dapoach says:

    Though this is my very first time of coming across the waterpik WPv660device. Its incredible to know that it pumps water at high pressure in between the gum and the teeth. Sometimes am amazed when i see the extent to which technological inventions are being borne daily. Also its ten different pressure setting makes the device a very flexible one. Thanks so much for this write up, it has really been helpful.

  • Tolu says:

    Thanks for taking the time to write this review on Waterpik Wp-660.Waterpik  indeed is a nice product. That is exactly why the American Dental Association recommended it. The features of Waterpik makes it stand out among its competitors. The truth is not everyone would like a product, but with the over 13,000 review with 4.4 rating, it is clear the equipment does it work well. Waterpik is an upgrade on regular flossing.  Above it, with the 3 years warranty on the product, disgruntled customer can always return it. I recommend the product.

  • Claudia says:

    Hi, I really like this flossing system since its really hard for me to floss the back of my teeth and specially my retainer. Does this come in a smaller version? I have an electronic tooth brush but this one seems better since it comes with a flossing system.

    Also I noticed it only brings one round tooth brush, can they be bought separately?

    I enjoyed the article but found it a bit too long. 

    • Teeth Man says:

      Hi Claudia

      Unfortunately the waterpik does not come in a smaller version, although you could opt to go for the portable water flossers which are smaller.

      Yes you can buy separate brush heads for the waterpik.
