Economical but double up treatment for 3 days.
Economical way to whiten teeth beyond whitening toothpaste. I had heavily stained teeth from tea and coffee, but I saw clear improvement after 3 days of doubling up the treatments. I did two applications per day for 3 days. These strips are only 6% peroxide so I figured I could double them up for a few days - one hour each day, then back to the once per day 30 min applications. Also a challenge if you had no braces growing up, like me, unfortunately. These strips are worth the money but have reasonable expectations. Teeth do whiten up and appear more polished over time. I plan to use them in the future every 2-3 months for regular maintenance. Four stars because one of the treatment application packets was defective.
