Tanda 90300 Tanda Pearl Ionic Teeth Whitening System

We got this particular teeth whitening kit because it was on sale and was recommended some months ago by Dr. Oz. We opted to do the 5 day treatment versus the 50 minutes all at one time treatment. It was relatively easy to use and the cleanup afterwards was a snap. We definitely noticed a difference in our teeth at the end of the 5 day treatment. I only gave it 4 stars as I was slightly disappointed that it was not quite the difference I was hoping for. However, my husband did the treatment at the same time as me and was 100% satisfied with his results. So it is a personal thing for me and has absolutely nothing to do with the product itself. My only other issue is that you have to buy the booster kit every two to three months and unless it is on sale could get a bit pricy.

I have used this product, as directed, nearly every day for approximately two weeks. Regrettably, I do not see a noticeable difference in the whiteness of my teeth; at least not yet. Perhaps it just takes longer with some people than others, so I haven't given up yet, but the results so far have been disappointing.

I love this product! In only five minutes per day for five days, you get a noticeably whiter smile without looking unnatural or making your teeth sensitive. The gel is individually packaged making it easy to dispense without guessing or messes. The mouth tray is easy to use and clean. I will definitely be ordering refills for this product!

Tanda is asking you to use this product a few times and then throw it away. It is expensive, but when the battery is dead, you cannot replace it and Tanda will not repair it. Rather, they offer a NEW machine for ONLY $99. It is an ecological nightmare. The battery cannot be removed and thus it cannot be properly recycled. So, you throw away batteries, as well as plastic in the case and the machine. What a terrible way to extract money from an unsuspecting public.

I was reluctant to purchase it because I have used whitening products that have not worked for my teeth that is grayish due to a previous root canal. To my surprise it actually improved the color to match my other teeth which will save me from veneers. I hope it will really last as long as manufacturer states. Only comment is that you use up a lot of gel, but it is worth it.

Ordered this product for it's over-all coverage, 5 min sessions & useful tray claim vs. using strips. After the 1st use, my gums all along my jawline (away from the teeth) were totally irritated. I figured it was the gel getting everywhere? But, it's actually the very uncomfortable tray that is a firm plastic. It does bend slightly, but not enough to be comfortable or gentle on your face - and is not custom like a mouthguard would be. I'm also not sure using the time-tray does anything more than just time it for the 5 mins. There's no light coming from it other than the indicator light. I am seeing great results in whitening & will use the remaining gel with the Walmart mouth guard I fit to MY teeth!

This system is not very effective, at all. I was disappointed that I wasted so much money on 2 of these and the booster set.

Quick and easy to use. Not irritating to gums. Not quite as much whitening as expected.
