I'm not newbie when it comes to teeth whitening.
In college my dentist actually told me to slow my roll if I wanted to still have enamel one day.
Thank you cheapo whitening trays from the early 2000's!
Since I'm immediately drawn to people's teeth I put a ton of stock in my own. A pretty smile makes a world of difference, the only problem is trying to figure out how to enjoy your favorites drinks (I'm talking coffee and tea over here!) and not look like you have George Washington's smile.
