LINHART Teeth Whitener Gel with Hydrogen Peroxide, Tooth Whitener for Sensitive and Normal Teeth - No Sensitivity, Effective, Whitens Teeth with 50% More Strength

I’ve been using this for a good while now in conjunction with linhart toothpaste. I am a heavy smoker & coffee drinker, both of which leave me embarrassed to smile around people I don’t know afraid of the “non-smoker” judgement of my teeth. I’ve tried several different whiteners that promised results but always fell short of my desired results. Immediately I noticed a difference in the way my mouth felt, clean & fresh as if I had them professionally cleaned. After a couple of weeks I noticed a huge improvement in the coloring of my teeth. I also noticed my breathe stayed fresh much longer than it did using a regular toothpaste. I don’t find the taste or smell to be overwhelming & also hasn’t irritated my sensitive gums or teeth. Overall, I am impressed with the product & it’s effectiveness, it by far exceeded my expectations.

When I first use this I put it on top of strawberry toothpaste and that flavor combo was a little odd. I have been using it on top of mint toothpaste and that is much better. By itself it has a light mint flavor but it is recommended to put over your own toothpaste. The flavor reminds me of having those white strips in my mouth and the strange aftertaste they give. It does rinse cleanly though and does not leave an aftertaste after brushing. I drink a lot of coffee everyday so I think I am fighting with my whitening but I am noticing a small difference already. I like that it is less abrasive and better for my teeth than the charcoal powder I was trying before.

*** Update - I contacted the company about the problems with the product I received, and they sent me a replacement. They agreed that I may have gotten a bad batch. The replacement was definitely a gel and the tube has been changed to have a smaller opening. These two changes alone make the product so much better. I've updated to 4 stars.***I bought this at the suggestion of my dental hygienist. I knew it was expensive but thought I would give it a try. What I got was not a gel, but instead a very watery liquid. What's worse is that the opening is larger than my normal gel toothpaste and this watery liquid just pours out, over the toothbrush and down the sink. Trying to pour it slowly only results in it dripping down the tube. Some of the other reviews have the same complaint as me so maybe we all got a bad batch of the product. But for $28, that's pretty bad. After 3 weeks of use, it's almost gone and I haven't noticed the slightest whitening of my teeth. Of course that could be from most of it being spilled rather than going in my mouth.

The first two tubes of whitening gel I used were actually gel. I also purchased one for my granddaughter which was also a gel and she liked it and said it was easy to use. We both had good results using the gel. Our teeth were visibly whiter. My third tube was liquid. I lost quite a bit my first use not expecting it to be liquid. No matter how much I shook it, it was still liquid. I am reluctant to order another tube. It is pricey and not to get what is advertised as gel is not worth the risk. I'll find another product.

Watery and not in gel form as the product should be, literally not useable! So disappointing I have used this product before and it’s never been like this.

This is a really easy to use tooth whitening gel. It's easy to use, as you just put a little drop on your toothbrush with your paste or powder and brush like normal. I was very surprised by the taste, as it's very light. Not overpowering at all. As I've been using it I am really impressed with it. It's much better than using messy trays, as you don't have to deal with all the fuss. Just brush and be done. My teeth have felt very polished and I love the confidence I have now that my teeth are getting whiter.

So far I’m liking this whitener. It doesn’t have an over powering minty taste which is nice. Just add it on your toothbrush while brushing! Super easy and I don’t have to set aside time to sit with strips on my teeth. Most teeth whitening strips make my teeth sensitive after a couple uses. So far I’ve had zero problems with this stuff and have been using for a couple of weeks. I’d say my teeth look brighter!
