Patient Information

Whether it’s your first visit or your fiftieth, we want coming to Comprehensive Family Dental to feel simple. This page covers everything you need before your appointment: what happens at a first visit, what to bring, how insurance and payment work, and how to reach us.

What to Expect at Your First Visit

Your first appointment is mostly about getting to know you. Here’s how it usually goes:

Check-In: Our team confirms your information and insurance, and helps with any paperwork you haven’t finished.
A Conversation: Dr. Jay Lien asks about your dental history, any concerns and what you’d like from your care. If you feel nervous about the dentist, this is a good time to tell us.
An Exam and Digital X-Rays: We check your teeth, gums and bite, and take any X-rays you need.
Your Plan: Dr. Lien explains what she found in plain language, walks you through your options and answers your questions. Nothing happens until you understand it and agree.

Plan on about an hour for a first visit, so nobody has to rush.

What to Bring

A photo ID
Your dental insurance card, if you have one
A list of the medications you take
Recent X-rays from another dentist, if you have them (not required)

You can find forms and more first-visit details on our new patient page.
