I recently got braces as an adult. I needed them to straighten my teeth and also correct my bite. 
Wow, it must be quite an experience. Is it worth it?
I hope it will be! Would you believe that braces date back to ancient times?
What types or categories of braces are there and what type do you have?
They can be either cosmetic or structural. I have Invisalign, and they are supposed to help me with both problems.
Amazing, when did the practice of using braces start?
Apparently around 400 BC, Hippocrates and Aristotle were writing about ways to straighten teeth!
Doesn't  the process have any impact on the surrounding gums?
I'm not sure. I haven't had any problems with my gums yet. The gums help surround and protect the teeth -- I don't want to damage them!
Nice. Does the process require the use of medication?
