How to Get the Most Value From Your Second Opinion

1. Get copies of your X-rays — under HIPAA, your dentist is legally required to provide them 2. Get the treatment plan in writing — including CDT procedure codes and costs 3. Note your symptoms — or lack thereof 4. Ask specific questions — "Is this treatment necessary?" is more useful than "what do you think?" 5. Choose an independent reviewer — someone with no financial connection to your dentist
