You need a new dentist mate. I had a zirconia crown fracture after only two years and my guy replaced it for free. If he was really hungover he might have a substance abuse problem and reporting him to the state dental regulatory authorities would be more productive than smashing a windshield (maybe not as satisfying but if you were caught on a surveillance camera you could have been arrested ... cameras are everywhere nowadays.)
ugg flashback to a dentist many decades ago that smelled like booze when i went in for an emergency major toothache. if it were not for the pain from the tooth i would have noped right out or there but the pain was paramount in at that point.
he did a good job, but i never went back again.
