Invisalign

I decided to get Invisalign. It is something I have been debating for the past 7 years, but put off due to the expense. I finally decided to go for it. My teeth have never been overly crooked, but they are starting to get more crowded on the bottom, which will only continue to worsen I'm told. The main reason I'm doing it though, is that I clench my teeth when I sleep which is causing headaches and the enamel on my teeth to wear off. My teeth are very sensitive and I don't want it to keep getting worse. I was given 19 trays. I'm supposed to wear each tray for two weeks. I have to keep them in 23 hours a day. I take them out when I eat. I'm excited to see the end result!
