After surgery and radiation, I couldn't stick the tip of my index finger between my uppers and remaining lowers. That's OK, I was pretty much limited to eating smoothies and such, trying to gain back a few of the 62 lbs I'd lost.

It's three years later and I can open my mouth as wide as I want to. In fact, it only took abbout a year and a half. No special tools, no therapists, no no exercises.

Maybe the tools and treatments would have made things go faster, but they weren't necessary, at least for me.

Hang in there!

P.S. A bigger incinvenience for me was the inability to eat spicy food. Couldn't do it for ages. As of a few months ago, I can. Mexican, Thai, Indian... bring it on, baby.
