Before you book

Five-minute checklist before you call

Federal data tells you a dentist exists and is enumerated. It does not confirm insurance acceptance, current availability, or office fit. Use this list when you call so the visit isn’t a surprise.

  1. Confirm insurance & out-of-pocket cost

    • “Do you accept my exact insurance plan? (give the carrier, plan name, and member ID)”
    • “Are you accepting new Medi-Cal Dental patients right now?”
    • “What is the out-of-pocket cost I should expect for the type of visit I need?”
    • “If you are out of network for me, can you bill my insurer or only me?”

  2. Verify the dentist & availability

    • “Is Audrey Jung-Sun Yoon the dentist who will see me, or another provider in the practice?”
    • “Are you accepting new patients? When is the next available appointment?”
    • “Will the same dentist handle follow-up visits, or rotate?”

  3. Verify the license yourself

    Search the Dental Board of California license-lookup to confirm the license is active and in good standing — federal records do not show state-level discipline. Open the Dental Board of California site →

  4. Match office services to your needs

    • “Do you offer emergency or same-day appointments? After-hours number?”
    • “What languages do your front desk and clinical staff speak?”
    • “Is the office wheelchair-accessible? Any accommodations available on request?”
    • “Do you offer sedation options for anxious patients (nitrous, oral, IV)?”
    • “Do you treat pediatric patients in this practice, or refer them to a pediatric dentist?”

Ready to call? Have your insurance card and a list of symptoms or visit reasons in front of you.

About orthodontists

What is a orthodontist?

An orthodontist focuses on tooth alignment and jaw position. Most of their day-to-day work involves braces, clear aligners, retainers, and the diagnostic planning behind them. Orthodontists also coordinate care for patients with cleft palate, severe overbite/underbite, or jaw-growth issues that may need surgical orthodontics.

Training. After dental school, an orthodontist completes a 2- to 3-year accredited residency in orthodontics and dentofacial orthopedics. Many also pass the American Board of Orthodontics certifying exam (board-certified status is voluntary).
