Just back from another session at the dentist of pre-work for getting last year's root-canal tooth crowned.
The gum is almost healed now that the temporary is holding the tooth together, but it's not yet ready for the rest of the work. So this was a session of tooth-filing. Not filling, filing. So I have been being ground down…
Over the last few years fillings that have meshed locally when I bite on the affected area, with my mouth full of cotton wool padding had managed to throw the global articulation off so that I could only bite on one side at a time. Since the root canal last year, I also had a tooth that was known to be cracked and I didn't want to put pressure on (even though it felt misshapen), which threw load onto the other side, and eventually caused cracking that led to Septembers' root canal.
Now, after an hour of biting onto articulating paper, and drilling to remove bits of fillings, I can now not only bite evenly on both sides, but, once more, bring my front teeth together (from the default slight underbite) to do things like tear sellotape!
