@JonnyH I had a mole removed when I was 8 but that's it... I've been under anesthesia only then and that didn't require me to change what I eat for a few days
I had mine pulled maybe 5 years ago, and it wasn't bad at all. They numbed my gums up, and I didn't feel a thing. There's a lot of worse dental work like I've had a root canal where they hit all kinds of nerves with that. Good luck, you'll do fine!
