So, here’s a thing I didn’t know—it seems your teeth can move as you age! I’ve noticed a gap between two of my front left teeth getting wider and wider, and finally I asked my dentist to fix it. It ended up being just treated as a standard filling under a standard consultation time, so it cost no more than any other filling I might have. And it filled the gap!
Here’s how my teeth have moved over the past 13 years:

2018 – gap is noticeable between the left central and lateral incisors (front left teeth, as shown on the right in this picture)
Thanks for the info. i have had a gap on some back teeth, and wondered what was happening.
yep, I now have a gap between my front two bottom teeth and the gap between my front two top teeth (that I’ve had for years) has closed !!! oh the joys of getting older 🙂
