I have purchased whitening gels from my dentist for years but thought I would try this to save money. After only 10 (painful) minutes my gums were literally throbbing....for the record, I have a very high pain tolerance (natural childbirth). My real concern came later as my teeth were aching (it felt like the pain was radiating all the way to the roots) so badly that I could not eat for the rest of the day. My teeth feel fine again today, but the experience was highly concerning to me. I have never experienced anything like it, not with national brand strips, generic whitening strips or dentist provided gel for trays.

I have a tooth on one side that bothers me now and then. I use this for a few days and the sensitivity goes away.

I liked the pain relief, but I probably did some things wrong. I got to the point where I was in more pain in the mornings until I had my first 'dose'. It felt like I was becoming addicted and I was experiencing some muscle cramps that I had not had before. I still like it and may start again in the future. Another problem was the increase in price. It increased $2 or $3 each time I ordered it the last few months.

Molds so strongly to my teeth that I have to readjust it periodically or it feels like its moving my teeth like a retainer.

After a week of using these, my teeth hurt so badly, it was miserable.  A few weeks after stopping using them and I'm finally feeling better.  Do not buy these.

I was very excited to try out my UP and enjoyed it for about a week.  One night, tossing and turning (no fault of UP) the bracelet must have shifted on my wrist and sent a shock throughout my arm that was incredibly painful.  I felt it from my fingertips to my shoulder.  I removed it as quickly as I could.  The next morning, my fingers are still tingling and my pinkie is numb.  I am especially sore at the point of the shock and ache up to my shoulder.  I have read about static issues, I don't have a wool blanket, cotton sheets.  This was very frightening and painful and I have sent my experience to Jawbone's customer service.

With the first bowl I felt there was something gritty somewhere in a bite, but did swallow it.  The next bowl I found a little ball of rock (?) about the size of a groat, very round and very, very hard.  I am so thankful I did not bite down on it hard enough to crack a tooth.  The flavor was very good, but I'm tossing it all out.  Maybe I'm the only one to have this problem - but I won't be buying any more of this product.

After walking in these shoes all day, my right foot at the top bone part was aching but i think it's just because i have like a lump right there.

I purchased these after having tried this specific crest strips before and having great results with no pain. However this time, the strips did not taste slightly minty (as the previous box had) and instead smelled a little of chemicals. Immediate sharp tooth pain from all three strips I have tried - will not be trying again. Gutted, as I had thought these were a great product but I've definitely got a duff box of them.

Great product, I had my doubts about its effectiveness but after finishing my box up I can safely say this stuff works, and well at that.

Pros-
Whitens nicely, I had dull yellow teeth before, now they're white. Not eye-blinding white, but white.

Easy to apply

Doesn't taste bad like some of them do

Cons-
When I first started using these, my teeth hurt like hell. Every time I yawned it felt like needles were poking my gums. Thankfully that only lasted for two days and I only had a little bit of sensitivity near my gums later on.

The packages are kind of dumb. I almost ripped one of the strips because the 'tear line' is so close to them.

After a week my teeth weren't white. After 2 weeks I wondered if I kind of noticed a difference but there is definitely no definite whitening action.

Which is too bad because I really suffered using this toothpaste. I don't know if burning like fire is supposed to make me feel like it is working. But this is just burns. My lips hurt. My mouth hurts. My tongue is not speaking to me. There is a point where mint goes from "refreshing" to "chemical weapon". I think Colgate missed that line.

If you are an actor and need to cry for a role, I suggest this toothpaste. But if you like your mouth find something else.

I really wanted to love these and I'm a very open minded person when it comes to things others find "icky" but this was just gross. I felt like I had to give it the old college try and use them at least 5 times and all 5 of those times I had that feeling right before you have to take really yucky medicine. Afterward my breath smelled fun (florally-lemon) and my teeth felt clean, but they just made the act of brushing my teeth so unpleasant that I couldn't continue with them. I love Lush, and I can't wait to try different flavors, but this wasn't for me.

A long time ago when I was a teenager I went to the dentist to have a root canal surgery done in one my molars.  I was given anesthetic and as the dentist starting drilling I felt the sharpest pain in my entire life.  I pulled the dentist's hand out of my mouth and yelled out loud in agony.  He went on to explain that some people do not assimilate the anesthetic as well as they should.

Now that you have that mental picture in your head.  Watching this movie will make you wish you were having a root canal surgery without any anesthetic.  Yes, it's that bad.

After using listerine total plus whitening a couple times, I started feeling a numbing sensation. I thought it was just doing its job. The last time I used it, it burned like you would expect but I tried to swoosh as long as I could. Maybe after 30 sec the pain was escruciating! My eyes were tearing up, and I had to rinse with very cold water. Before I knew it, my lips and my cheeks began to swell. This is day 3, and all I can eat is frozen yogurt (no chunks) and popsicles. I am still swollen, and the inside of my mouth is in pain kind of like the way canker sores feel. My gums are still inflamed. I will give it a couple more days to heal before I decide to go see a doctor. I have decided to call the company which is part of Johnson n Johnson. If you read other reviews, apparently this has happened to other people. I don't know how this is FDA approved.

It may just be me, but this gum makes my tongue feel super sore a few hours after I chew it and I get lie bumps all over. Makes it very hard to eat and I can't taste anything...but like I said, may just be me. My mouth does not like this gum.

I've been using this product for a few weeks to a month or so now, and at first it was more of a shock to my mouth with so much "Vibration" but i guess thats how it cleans, i just had to overcome the tickling sensation in my mouth and on my teeth........
My son (whom i brought it for) tryed it and struggled so much with it, that he did not want to use it ever again after only the first try...
So i've been using it every day now and i find its not able to clean hard to reach areas and i still have to go back and use my (hand) tooth brush.
Because it "Vibrates" like an "Orbital Sander" in my mouth i often wonder if i should have purchased a electric tooth brush that "Spins around/Rotates " instead of "Vibrating"
But, oh well..... i got it now and i guess i just got to make the most of it
(oh - the other pain in the butt (or mouth) is the "Settings" are such a pain - you cant just press a button to set what you want - you have to press and hold one button for  X amount of time or hold same button for X amount of time to change settings (Oh My God) seriously ...you have to count the time you hold the button or else you don't know which setting you just put it onto..
For $260 AUD i would have thought it would be a much better refined product

Pros:
Lower settings felt nice on my gums and I am sure it cleaned off the more easy-to-remove particles from my teeth.
Was a good way to rinse the gaps around my implant and I could tell water was getting under the gums in that area due to the larger gap between the implant and my gum tissue.

Cons:
Medium setting really hurt my gums and the soft tissues of my mouth so I had to turn it back to low.
Water got absolutely everywhere in the bathroom. EVERYWHERE. The counter was covered in water spray.
This thing is very noisy. I read reviews on other models which look similar, but white, and some people said they had quiet operation. So who knows, maybe I was unlucky? But I would feel very embarrassed to try to use this living with a roomate. It would definitely wake someone up in the morning.
I did two passes over my teeth, so basically 'flossed' twice. Then I used my regular dental floss to see what was left. Well, it seemed like I never even flossed because my regular floss removed pretty much the normal amount of stuff that I am used to seeing. My teeth are very close together so maybe that's why?

I am returning this item tomorrow because I really can't see that it works for me. I can see how it might benefit people who don't have the hand dexterity to use normal floss, because at that point at least it would be better than using nothing. Sorry!
