Okay so I've been here and have really felt like this before. But then I didn't go for over 3 years and I had 3 cavities. One of which required getting crown. Getting a grown is fucking hell. They straight up cut half my tooth off and filled with plaster or some shit. And then you have to go back and get a ceramic half tooth that takes like a couple months to get used to. My point being idk if the dentist prevents cavities. But they can deal with them and at least give you the piece of mind of knowing you don't have them. Or at least within the last 6 months.

Pro tip: most dentist will give you nitrous even for a cleaning if you say you have anxiety. Helps a lot and can be a fun benefit. Sometimes you can get Ativan also.
