I stopped into the orthodontist yesterday for a test fitting of new Invisalign trays. I was alarmed to learn I’ve been doing this for almost three full years. I’m probably the poster boy for the extreme edge of what is possible with Invisalign. It’s been a long road, but my teeth have made major improvements. I have noticed that changes have slowed down in the last six months; I wasn’t sure if I was imagining it or not. Meanwhile, our orthodontist recently retired, sold his practice to a new guy, and this new guy is taking a different tack with my final series of trays. He actually re-scanned my teeth and moved a couple of the nubs on my teeth around to better hold the trays to push my front teeth out. The new trays fit my teeth better now than they ever have in the past. I’ve probably got another six months before there’s any chance of me being done, but I will say that I’ve gotten my money’s worth out of this process.
