I've often thought that her teeth were very straight, but I noticed during one of her SAGA videos, her teeth certainly looked far less than perfect. I wonder if it might have to do with her wearing braces at some point. Many years ago I had the invisalign process done to straighten some teeth out. By the way, I had some back teeth that were way out of place and the process worked very well to straighten them and all the other teeth out. I believe the process took about a year and 3 months. You go through a process of wearing these plastic covers that are molded to the shape of your teeth. Each one in a progression shifts your teeth a small amount. You wear each one for about 2 weeks.
Well one thing about the process bothered me a lot at the end that I wasn't aware of in the beginning was that when the process was done, you were still expected to wear a retainer. If I had known that from the beginning, I probably would've done that, but I was so happy to be done with the process that when they told me about the retainer, I wasn't willing to put up with it any more at that point and didn't use them and my teeth shifted back, though not as bad as before.
So I'm wondering with her if she had braces or the same thing I had and then stopped wearing the retainers, or is it possible that she could've worn something to give the appearance of perfect teeth, but if that had been done, the chipped teeth I'm sure would've been covered up too and I don't think they were at any point, but can't say for certain.
