Review on Ultimate Teeth Whitening: Crest Whitestrips SUPREME Professional Whitening by Duane Mejia

There's a reason this whitening product isn't commercially available. (These are usually only available from dentists.) I've tried all the strips in the store, including the light ones, and nothing beats these strips. Ideal for brightening. Even my dentist loved it. Pros: Hands down the best whitening strips. I've bought many boxes over the years. CONS: If you have a lot of track slip issues, you might not like this. I try to dry my teeth as best as possible and press firmly before applying. In addition, the product is strong and your teeth and gums can become very sensitive. Just reduce the frequency of their use. The sensitivity really goes away. Product was received quickly and all strips were present with an expiration date of March 2021. I recommend both the seller and the strips!
