You'll be fine then
Plus, it's freezing up there, isn't it?
I'm in Texas and it's freezing here, lol.
And it's just a mild fever, so you will be okay.
Keep an eye on it...but dentist do these things everyday and they know what they're doing.
If you are super worried, just call and ask them about it.
But I suggest that you sip on some calming tea or something and just relax
