I received T-spray Cosmetic Teeth and Oral Spray for free in exchange for an honest review. It is a non-toxic, natural product you can swallow without worry. I like it, I give it 4 out of 5 stars for being a pretty good product. My only complaint is the taste is too strong for my teenage boys. It makes your mouth feel clean at any time of the day, and it is so easy to use. You just put it about an inch from your mouth and spray. I took a before and after picture while I was using the spray, and here it is.
You can buy the product here on Amazon:
I also made a YouTube video about the product.
