I discovered the other day that my teeth looked a lot whiter, at closer inspection I also noticed that my front teeth looked smoother around the corners. Those corners used to be really sharp and now it's as if the tooth has somehow grown a little, filled itself in with new enamel.
I know the lighting is totally different in the images however you can still see how soft the corners are and how there are no more differences in colors. Note the very low edge of the front teeth, they had a yellow discoloration all my life and it got worse on low carb and now after three weeks of RBTI it's totally gone (that's not due to any lighting trick or anything).

On low carb I also developed my first ever cavity and by the end of it I began noticing that my front teeth had grey stripes inside of them from what I guess was some kind of demineralization process. That was too depressing to even take a photo of. It disappeared as soon as I started RRARFing thankfully. But the yellow shading remained and so did the sharp edges that I had considered asking a dentist to fill in with some kind of porcelain. Now it looks like I won't need that.
