I had one done recently due to breaking a filling while eating a Jolly Rancher. The whole thing took maybe 2 hours.
The shot of novocaine to numb my jaw was the only pain, and even that wasn’t bad because the dentist used topical numbing before that. It was no different than getting a cavity filled.
My dentist has a cnc machine (CEREC) in the office to make the crown, so I didn’t need a temporary cap. Waiting for that to be milled was the longest part.
I had a bruise on my gums for a couple days from the shot and the retainer clamp, but it wasn’t even bad enough to stop me from eating.
If it’s raining, there’s snow on the ground, or many other low traction scenarios, the cop would have to really want to pull you over. Chances are they won’t.
On a clear, dry day, depending on where you are, barking your tires is a violation of nuisance laws. Again, most likely not getting pulled over unless you consistently did it.
Now, if you stomped on it and your tires broke loose, you are looking at reckless operation of a motor vehicle. Expect to be stopped.
It mostly comes down to conditions and level of egregiousness… and how bad of a day the cop is having / wanting you to have.
