Whole Person Care That Starts With Your Smile

A dental visit should support your overall health and well being. Our team focuses on more than just teeth. We care about how you feel during your visit and how your smile supports your confidence and health long after you leave. Our practice is built around reducing the time you spend in the chair so you have more time to enjoy life. 

Enjoy Relaxed Care On Your Terms

Your comfort always comes first. We offer multiple sedation options including nitrous oxide, oral sedation and IV sedation so you can choose the level of relaxation that works best for you. Prefer a lighter approach. Simply settle in and enjoy your favorite show on the screens in front of and above you. Every detail is designed to help you feel calm and at ease.

Next Level Guided Biofilm Therapy

Guided Biofilm Therapy is a modern approach to preventive care that’s ideal for patients with sensitive teeth, implants or dental anxiety. This gentle treatment removes harmful bacteria while protecting healthy tissue. The result is a brighter smile, healthier gums and faster appointments that feel refreshingly comfortable.

Advanced Laser Care Means Healthier Gums

Laser assisted gum treatment offers a minimally invasive option for improving gum health while preserving healthy tissue. This advanced approach reduces bleeding, speeds healing and can shorten recovery time by as much as fifty to seventy percent. It’s another technique we use to provide a more comfortable experience and benefit patients’ long term health.

I highly recommend Dr. Castillo & her staff. She is very thorough & knowledgeable. My hygienist, Jill, is excellent & has a light touch. Everyone is very friendly and address all questions & concerns you have. I have had poor dental experiences in the past and have had difficulty finding a group I trust and feel confident in. So far my visits here have been positive & I feel really good about continuing care with them!

This Office is by far one of the best dental offices known to mankind. Dr Tran is beyond knowledgeable in her field and super patient.I used to hate going to the dentist until I found them. She is so professional and takes pride in what she does by making sure you’re well informed and comfortable through out the whole procedure.The office NEVER outsold me with unwarranted treatments just because of your insurance coverage like other offices. I feel so blessed to have a dentist I can trust. I highly recommend Floss Dental. Honestly, she’s the real deal.

This is only my second time here and I won’t be going anywhere else! The office is clean and well kept, Tisha (I think she’s the office manager) is AMAZING, and so friendly. You truly feel like part of a family when you go there! Dr. Chung is literally the best with describing everything in ways you understand, tips on how to maintain your dental hygiene and talks you through the whole process. Highly recommend. If I could give more than 5 stars I would!

I truly appreciated the friendly staff who made me feel comfortable during my visit. The doctor also explained the treatment thoroughly, and helped me understand each step they took during my visits. I normally don’t like visiting dentist offices, but I would recommend this one. Really felt at ease.

I came to Floss on an emergency situation with an infected wisdom tooth.. after avoiding the dentist for 10 years I finally had to go in. The doctors and staff at Floss took the best care of me. I got all 4 wisdom teeth removed and just went back today for a follow up and they all greeted me with a smile and by name. I felt so well taken care of and can’t imagine going to another dentist.
