Hear From Our Happy Patients

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.

Frequently Asked Questions (FAQ)

New Patient Special

K

What is included in the new patient special?

The new patient special typically includes a comprehensive exam, X-rays (if needed), and a cleaning. Some offers may also include additional perks like discounts on certain treatments or free consultations for specific services.

K

Are there any exclusions or restrictions with the new patient offer?

We will assess your dental condition to determine if you’re eligible for the preventive cleaning included in the offer, as you may require a deep cleaning instead. If advanced treatment is needed, the $169 goes towards it. Think of it as an investment into your smile!
K

What other dental treatments do you offer?

We specialize in a wide range of services including dental implants, veneers, same-day crowns, clear aligner therapy, accelerated orthodontics, HealthyStart, root canals, tooth extractions, sedation dentistry (IV, oral, or nitrous), periodontal care, and more. Our team is dedicated to delivering exceptional results with your comfort in mind.
Biofilm

AIRFLOW® + Guided Biofilm Therapy (GBT)

K

What is AIRFLOW® + guided biofilm therapy, and how does it work?

AIRFLOW® + Guided Biofilm Therapy is an advanced, minimally invasive cleaning method that uses a special dye to highlight bacterial biofilm (plaque) on teeth. The biofilm is then gently removed using an air-polishing system, which is precise, effective, and comfortable for patients.

K

Is AIRFLOW® + GBT more effective than traditional teeth cleaning methods?

Yes, AIRFLOW® + GBT is considered more effective because it targets the biofilm directly, which is a primary cause of gum disease and cavities. Traditional cleanings may miss some of the deeper bacterial layers, while AIRFLOW® + GBT removes them thoroughly with minimal discomfort.

Insurance

K

Do you accept my insurance provider?

We accept PPO dental coverage from leading insurance providers including Aetna, Ameritas, Assurant, BlueCross BlueShield, Cigna, Delta Dental, Dental Network of America, Dental Select, DenteMax, GEHA, Guardian, Humana, MetLife, Principal, United Concordia, UnitedHealthcare.

K

How much of the cost will be covered by my insurance?

Coverage varies based on your plan, treatment type, and network provider. We will verify what’s covered by your insurance 24-48 hours before your scheduled appointment, and can assist with filing claims to ensure you get the maximum benefits.

Scheduling

K

How far in advance should I book my appointment?

We are now open and available for same-day appointments! It’s always best to book as early as possible, especially if you prefer a specific time or date. For regular cleanings, booking anywhere from 2-4 weeks in advance is usually sufficient, but for specialty treatments or during busy periods, booking a couple of months ahead is recommended. Give us a call and we’ll check our availability!

K

What happens if I need to reschedule or cancel my appointment?

Most dental offices have a cancellation or rescheduling policy, which may require 48 hours notice. If you cancel too late, you may be charged a fee. It’s important to call as soon as possible to avoid any penalties and to find a new time that is most convenient for you.
