What Brings You to DC Dental Spa?
For Nervous Patients
Twilight Sleep Sedation
Twilight sedation helps you feel relaxed and drowsy during treatment while you stay able to breathe on your own and respond. Most patients remember very little of the visit afterward.
We use it for longer procedures like implants and wisdom teeth, and for anyone who feels nervous about the dentist. We offer twilight sedation only. We don’t offer full IV general anesthesia.
Ask about sedation when you book and Dr. Hoang will tell you whether it fits your treatment.

Pricing & Consultations
Before You Call About Price
We don’t quote treatment prices over the phone, and there’s a good reason. Two people asking about “a root canal” can need very different care, and a phone quote without an exam is a guess.
Come in for a FREE consultation instead. You’ll meet Dr. Hoang and the team, see the office and get a written plan with options and costs before any treatment starts. You’ll never pay for anything you haven’t agreed to and signed for.
