Same - this is my first water flosser and it's worked great for a couple months now. My dentist told me the same thing, that the water flossers work fine for day to day stuff, but you still want to choose conventional floss intermittently. Like having your car washed by a touchless car wash vs. using a sponge yourself - both do the job, one just does it a little more precisely/better.

I bought my first water flosser almost a year ago and I thought it would be enough to replace normal flossing. I was very wrong and wish I had just kept my normal flossing routine.

I've recently noticed degradation in my overall oral health as I now have cavities between my teeth even though I have brushed and used the water flosser daily. I've now added normal flossing after the water floss and the floss still picks up bits of plaque. So a word of warning to anyone thinking this will be enough to replace normal flossing — it won't.

Second picture on Amazon product page. The cringe worthy smiling women with too much makeup and weird photoshopped amount of liquid around her mouth and oddly clinging to her teeth.

Yup. Great job offshore amazon product specialists! Doesn't have any creepy porn vibe at all 😉

Thread based one? You mean the one connected to the tank?

Your dentist wants you to keep using regular floss because these "water flossers" don't remove plaque, which causes gum/periodontal disease. You have to actually physically scrape the plaque off of the teeth, which the water doesn't do. So the water flosser doesn't prevent periodontal disease, which causes tooth loss, and has been connected to other diseases (heart) due to the inflammation it causes in the body. Water flossers can remove food debris, and massage the gingiva/gums. It would be best to use both, unless your dentist advises against it.

Lol, I actually hate that kind of cliche stuff but yes I am a connoisseur.

As for the nickname, I think I was just trying to be cheeky when making my account. But again, all things come full circle. 😂

As for adding actual value to the thread. My wife has one of these. I personally think they don't do as good a job as flossers and setup / cleanup is too complicated. The best thing I ever used it for was to irrigate/float out a splinter from under my nail. Ouch, but did the job.

Downvote prudes!

Anyone ever tried using dental water pick for car detailing (cleaning dirt off seams)?
