Cool Teeth Whitening Kit Fast Acting Gel for Sensitive Teeth, Led Accelerator Light Included, White, Mint, 1 Count

I had a little trouble making mouth trays like everyone else, and trimmed the upper tray down. This helped a lot but I had to trim out spots where it now has no contact with the top part of my teeth.I can tell you that my teeth are a heck of a lot whiter after using this product, because I can see spots i missed on my teeth that are a lot darker.This stuff does burn, but use a lot less then you think you would need, be careful and leave on for 1-2 hours. I know it says 30 minutes in the instructions but I got results with 1-2 hour sessions daily. It can help to lie down and just watch tv to stop your mouth from salivating too much, I have that problem.I wasted the first few syringes by using too much and wasting a lot of it, burning my gums, etc. Maybe I have super strong teeth because my gums healed over night and i only get a little bit of sensitivity to cold air.My teeth aren't white white, but a lot brighter and a lot nicer looking. I am not sure if you can ever fully bleach them at home to the fake white movie stars have, but I am about to buy another kit and find out!

Okay, I've bought a lot of items on Amazon but I never review. Given the importance and potential danger of this particular product I decided to write one. I have been using this for 3 days. 2 times a day for 30 mins a time. This isn't a one size fits all product but this is how I been doing it to great results. Amazing results actually. I was nervous and skeptical. The following is my instructions and experience:Step one, brush your teeth and floss.Step two, dry your teeth. I use a cloth then make sure to not close my mouth so they stay dry.Step three, application: DO NOT PUT THIS STUFF DIRECTLY IN THE TRAY. SERIOUSLY. DON'T. You won't get anything from it other then extreme pain and waste. (Thankfully I knew this already though.) Gums don't grow back and if you've ever seen anyone "long in the tooth" that's what you could become if you're not careful. What you do is take little teenie tiny droplets (a tiny bit goes a long way) from the syringe and paint your teeth with a Q-tip or paintbrush being very careful to not touch any of the gums. Get close to the mirror , concentrate and take your time doing this. Keep your mouth open and teeth exposed during this. I am not doing both rows at a time. My bottom row is more sensitive then top and really don't see the bottom teeth when smiling anyways. Also it's much easier to do a row at a time.Step 4, put on guard. Do it for a little bit first time to gauge how sensitive you are. Like 5 mins. Then take it off and wait a hour or so. If feeling okay then redo and go for 15. If feeling fine after that redo and go for 30. I personally wouldn't advise doing more then 2 30 min sessions a day. This stuff is super duper strong and dangerous. Honestly I'm very surprised that it's even legal to buy over the counter.Step 5, SET A TIMER. (use your phone or something but for real use a timer.)Step 6, Stick the light thing in your mouth. It prolly doesn't do anything because real dentist lights are costly and hit a higher range of spectrum but use it anyways just to look silly if you have it. It's part of the experience lol.*Don't swallow. If your spit builds up too bad in your mouth go spit and then put the light thingy back in. (This type of peroxide is loosely linked to cancer so best to not eat it if possible.)When time goes off remove tray and gargle with some water. Keep a glass by the sink to be prepared. Then brush lightly (teeth and gums will prolly be a little sensitive so don't push the brush too hard) with a good toothpase that promotes enamel health. (I use Crest pro enamel. Seems to rejuvenate using it before and after the bleaching sessions.I must of increased 8 shades in 3 days multiple applications per day so it totally works great but do be careful. Plan on doing it for another couple days Know your limits here and patience is virtue. I've only used half of one tube so far. Way more product then you will ever need so maybe get extra guards and share with friends and family.Your teeth are weaker during this time. They can also regress quickly during this time. What I've been doing is using the guard on top row when I smoke to keep it off them. Also trying to avoid coffee/tea but drinking coffee/tea with a straw and the guard in for each sip. (total coffee and tea addict here) 7 days after your last bleaching session you can go back to normal routine. Just brush a bunch while waiting those 7 days and use some fluoride mouthwash too. Maybe that blue remineralization gel. Whatever just hit them buggers with a ton of nutrients so they get their strength back and don't regress.If you follow these directions you will have results. They may not be the most dramatic and trust me you're never going to look like TV people and magazines cause thats nothing but a parade of veneers and photoshop but you will lighten up considerably. Just be patient and good luck!~ ^^

I can honestly say after buying this that I'm not quite so sure that it's 44% Carbomide Peroxide. Let me explain why. About a year ago, I bought 44% Carbomide Peroxide off of Amazon. I bought this from a different seller at the time. That stuff was absolutely legit! If any of the gel got onto my gums, I knew it within a matter of minutes. My gums were bleached white, and the zingers were there. I have fairly non-sensitive teeth, so I would leave that gel on for 45 minutes at a time. I got amazing results with this! In a matter of a week (with 45 minute treatments) my teeth had completely brightened to "Hollywood status white". Unfortunately, I have a crown on my front tooth which meant that my surrounding teeth were outrageously bleached, and the crown remained (dingy in comparison). Therefore I went into the dentist to have a new crown put on to match my newly whitened teeth. My dentist informed me that I had amazing results, and the crown would have to be special ordered due to them not keeping that shade in house. He even showed me a chart and said that there were three unnaturally white shades that they could order to try and match the crown to my surrounding teeth. I wasn't the absolute brightest, but I was one step off.Regardless, let's fast-forward to this order. I ordered this because after having my crown replaced, My surrounding teeth started to fade after 12 months of daily coffee's, tea's, and other foods that didn't really help. This was only a problem because my crown, (which obviously won't change color), remained a bright pearly white. This time my surrounding teeth began to look dingy in comparison to my crown. My solution was to order another set of 44% Carbomide Peroxide, with the hope of getting the same results as before. I WAS UNABLE TO FIND THE FIRST SELLER I PURCHASED FROM ORIGINALLY, so I went with "Cool Teeth Whitening" version of 44% Carbomide Peroxide.*Enter this product*I started using this product expecting to get the same results. The first 2 nights I was left expecting more. I put an ample amount into my custom trays (made at my dentist office), and didn't notice any immediate results like I had with my first experience. Due to this, I decided to do 1 hour treatments instead of 45 minute ones, and I gave it 3 more days using the same amount. After 5 days with very little results and NO SENSITIVITY WHATSOEVER, I decided to really put too much on. I put enough onto my trays that when looking into the mirror I could see it overflowing out of my tray and onto my gums. Despite having the gel sitting on my gums for an hour, they did NOT get bleached whatsoever. I also did NOT get zingers. After trying this method, the only thing stopping me from fighting to get my money back, was the fact that I could vaguely notice my teeth were actually starting to whiten. The next night I decided to really put this product to the test. I did a one hour treatment, emptied and cleaned the tray only to refill the tray and do another treatment. In all, I did 5 hours worth of 1 hour treatments and ONLY THEN did I notice decent results. NO BLEACHED GUMS AFTER 5 STRAIGHT TREATMENTS. NO ZINGERS EITHER. The beautiful thing about having a crown in the front of my mouth, is that I know exactly what shade I'm trying to match. I know what shade I was capable of reaching, and this made it easy to know what results I should expect. I don't recommend anyone try 5 1-hour treatments with a real version of 44% Carbomide Peroxide. This is worth mentioning because there is no possible way that I could have done this with the first set of gel that I ordered a year ago. Just the though of sitting through 5 1-hour treatments with that solution back to back sounds like torture.I'm in no way claiming this product doesn't work. It just doesn't work nearly as well as the first 44% Carbomide Peroxide I ordered. Not even half-way as well as the first. Only possible solution I can think of, is that that either the first set I ordered were over concentrated, OR these were under concentrated. I've only ever used one other 44% Carbomide Peroxide, so I am unsure which was truly 44%. What I can tell you is that from all the reviews I read online, the first set I ordered was most likely the 44%. This stuff is probably closer to 20% (If I had to guess). When I do my treatments, I make sure to do it a certain way, so that my saliva doesn't just wash away all the gel. I probably look really stupid while I'm whitening my teeth, but it worked well the first time around. I obviously know how to do this correctly or else I would not have gotten such good results the first time around. I hope this review can reach someone serious about whitening their teeth. I got amazing results with another sellers 44% Carbomide Peroxide gel. Not this particular sellers version.
