Hear From Our Happy Patients

At FLOSS, we’re dedicated to truly understanding and caring for each patient. We take pride in listening closely and making sure every need is met with compassion.

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!

I have extreme anxiety and negative experiences with dental offices. Floss dental was an excellent experience and the staff was very professional. Dr. Castillo was awesome!!! I would definitely recommend Floss dental in Magnolia, Tx.

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.
