So much better than string!

This is a wonderful addition to my dental care. I'm so glad my hygienist suggested it. I have hard to reach spaces and this makes it super easy versus me fumbling around and cutting my gums. I'm happy with the results and my mouth feels cleaner.

Yes, I recommend this product.

Works well, no problems yet! The instructions and use of tips is a little bit complicated for a non-dental professional to figure out.

What finally broke...

21 days ago
I have used this nearly every day and sometimes more than once/day for years. What finally gave out was not the motor - but the hose. It developed a slight hole in the hose right at the base where it connects to the tip, probably because the hose is rather long and it has a tendency to get kinked. Wrapping with tape did not fix it, and it does not appear that it can be replaced. Seems a shame to toss it just because of the hose - but I have definitely gotten my money's worth out of it and am going to get another one just like it. This little machine has been instrumental to my dental and overall health. Thank you, Waterpik.

Yes, I recommend this product.

Loving my water pik!

25 days ago
I love using this thing! It's convenient sitting on my sink. The only draw back is that it's a little on the noisy side but it works beautifully. I love that you can turn the nozzle to reach all the teeth better.

Yes, I recommend this product.

Q: 1. Is there a way to use the whitening capsules with these model? 2. Which is better the 360 degree rotation tip vs swivel handle?

a month ago
1 Answer

A: Hello- To use the whitening tablets on this model, you will need the Boost Tip accessory. You can find this tip here: https://store.waterpik.com/products/wtt-1ww?_pos=1&_sid=cd79951de&_ss=r. Choosing between a 360-degree tip rotating handle and a swivel handle depends on personal preference. A 360-degree tip rotating handle allows for full rotation of the tip, whereas a swivel handle lets the entire handle pivot without the hose rotating along with it. Both features enhance ease of use, so it’s best to choose the one that feels more comfortable for you.
