What to know before you book
General dentists handle checkups, cleanings, fillings, and crowns, and refer to specialists for complex cases. Bring a photo ID, your dental insurance card or a payment method (many offices offer cash pricing or in-house membership plans — ask when you call), and a list of current medications. For a severe toothache, chipped tooth, or a knocked-out tooth, call and ask about same-day emergency slots; for facial trauma, uncontrolled bleeding, or swelling that affects breathing or swallowing, go to an emergency room.
