As often as I feel like now that I have free dental! *chuckle*. I've had so many things fixed in the last few months, a filling, wisdom teeth removed, chipped teeth smoothed and filed, scale and cleans... Heaps of things.
That being said, they're all things that have been needed to be done for AGES. I haven't had anything done to my teeth since I was in primary school and we had the dental vans coming around regularly because my sister had a serious overbite that had to be corrected and it was very expensive.
End result, my teeth suffered for it as they weren't as bad as hers heh. So now everything major-ish that needed work has been fixed and I'll probably go back every 6-12 months for a check up and clean .
