Dr. Rex Hoang, DMD, PC

We know that many people don’t like to go to the dentist so we make it as comfortable as possible. By utilizing the latest technology in dental treatment - such as laser dentistry - we don’t have to numb or give patients shots,” said Dr. Hoang. He’s quick to add, “We take them from fearful to fearless the moment they walk through the door.

Our Patients Love Us

I’ve been going to DC dental spa for more than 10 years. They have always provided exemplary, high caliber and personable service. Dr. Rex Hoang meets with all of the patients while also involving and building talent in the next generation of dentists, and performs any complicated interventions himself or under his supervision. The practice has always run smoothly, with reference to previous visits and continuity of record keeping over time to monitor any changes in the status of the teeth. Good adoption of technology to keep the practice up to date medically and from an organization/private practice point of view. Administrative staff are always friendly and accommodating. Running a few minutes behind? No problem, they take you when you arrive and there is no guilt. They also offer an introductory special for new clients that I’ve passed on to friends. While I don’t like going to the dentist, DC dental spa has made it a very pleasant experience. Highly recommend Dr. Hoang and company.

Fabulous all the way around. Bebe and Dr. Wong are extremely kind and attentive folks. Went to the same dentist for a decade before I went to DC dental spa, and now I feel like I will never leave them either!

DC Dental Spa is the best dentist in the world - or at least in the 3 continents I’ve been to the dentist at. From the minute I walked in, they made me feel super comfortable and welcome, talked me through everything step by step, let me ask as many questions as I wanted, ranging from “will this hurt?” to “why are we doing this?” and set out a treatment plan that I’m currently following. I’m a broke grad student paying out of pocket and they were so nice and transparent with costs, what was important to get done ASAP and what we could maybe take a little more time with. Literally everyone I’ve encountered here was AMAZING, from the front desk staff, to the person who took my x rays (and I’m a little phobic, so it wasn’t easy), Bebe (who is the sweetest and gave me a great rec on something that has nothing to do with dental care) & of course Dr. Huang. They make going to the dentist a genuine pleasure.

I’m getting my wisdom tooth taken out next week, which is something I’ve lowkey put off for 2 years and I feel good about it! (Ok, that’s a lie, I’m still terrified, but I’m glad I’m getting it done at DC Dental Spa!). Definitely go here, but not too much, so I can still get appointments. Can’t recommend enough!
