I have tried different white strips to erase years of coffee and tea stains from my teeth. I was left with slightly lighter teeth that were then sensitive to cool or warm food and drink. It felt slightly painful to feel air on my teeth! After trying Luster`s Pro Light Teeth Whitening System I will never go back. The results are fast, painless and beautiful.
