Let this be a lesson to you, kiddies — don't wait 8 years between dentist visits. :P Only diligence at brushing and flossing has enabled me to still have teeth at all. :P
Unfortunately, I'm back on antibiotics again because the one tooth was so far gone that part of the nerve had actually died. Since the whole process of a root canal is designed to go in and remove the nerve, that wasn't inherently a problem, but it does mean I have to be super-careful to make sure it doesn't get infected between now and then.
I'm sure you're all just pleased as punch to read about it, too. ;) At least it's my mouth we're talking about here!
