>>81462013 (OP)Dentists are glorified teeth brushers. Whatever they tell you they're more than likely retarded like doctors. They've likely have no real passion for dentistry anymore, they just repeat whatever bullshit they were taught in schools 20 years ago and push you towards doing shit that is more profitable for themselves like a doctor sending you off to buy a shit ton of meds.
Drink some ice water right now. Do any of your teeth hurt really bad? You may have a cavity though if you live in the U.S. thats very unlikely because they fluoridate the water.
Basically they'll just clean your teeth, tell you that you should brush more often(outdated bullshit) and tell you where you need to brush.
