Learn moreHow we work
Most patients arrive thinking it's a hygiene problem. The exam usually shows it isn't.
- Visit 1
We diagnose first.
Every visit starts with a halimeter VSC reading and a focused clinical exam. We identify the actual source of the odor before recommending treatment.
- Weeks 1-2
We treat the cause.
Tongue bacteria, periodontal pockets, dry mouth, sinus drainage — we match the protocol to what's actually driving your breath issue.
- Week 6
We re-measure.
Six weeks after treatment begins, we re-test VSC levels. Numbers tell us if the protocol is working — and we adjust if they're not where they should be.
The clinician
Dr. Teah Nguyen, DDS
A graduate of the University of Southern California's Ostrow School of Dentistry, Dr. Trang (Teah) Nguyen continues the work of Dr. Anthony Dailley — the founder of one of the few halitosis-focused dental practices in the Bay Area. She combines technical precision with a calm, patient-focused approach.
We intentionally do not produce or manufacture the products we recommend. We use only what independent clinical research has shown to be effective — a position we hold because it's the right one, not because it's convenient.

Dr Teah took over Dr Dailley's practice since he retired. She is an excellent Dentist, caring, considerate and very profesional. Highly recommend you see her!!!
Dr. Dailley has been my dentist for close to 10 years. As someone with complex dental needs, I was intimidated by different doctors after my childhood dentist retired, but Dr. Dailley’s careful treatment plan, steady hand, and amazing staff helped inspire my confidence in his entire practice. I recommend him to everyone I know. He looks after each of his patients and I appreciate his thoughtful approach that keeps his patients’ best interests in mind.
I can't say enough good things about Dailley Dental Care. Dr. Dailley and his staff are amazing. They are so friendly and helpful. They always get me right in and it seems like they take the time to get to know all of the patients and take a personal interest in each and every case. Most importantly the care is AMAZING. Dr. Dailley pretty much rebuilt my entire mouth and the results are so beautiful. I have a perfect smile now. I couldn't be happier!!! Definitely 5 stars!
I loved Dr. Dailley! amazing service! him and his office make sure you feel at home when there! all the girls are sweet and welcoming, I am glad I went to him...the dentist I was seeing before him was actually out for my money rather than my dental care!! glad I left that place and came here.....and not to mention the fact that he also takes his time to write you a thank you note for coming to his office! super sweet! definitely keeping him as my dentist!
Dr.Dailley and his team always do a great job. Getting appointment and arranging the appointment are really easy. The office is always clean. Dr.Dailley and his crew's hand are very gentle. There is no waiting time, they do their job in the right time. Thank you so much for their awesome work!
This was the best dentist visit experience I’ve ever had. I learned so many things about my current dental health. Dr. Dailley was very detailed and everyone in general guided me through the process, gave me tips, and explained what some of the dental terms were. Everyone was super friendly. The dental assistants would also check up on me often throughout the entire process. I felt comfortable and valued.
My wife and I have been seeing Dr. Dailley for several years now and we are more than satisfied with the level of care that we are receiving from him and his staff. Dr. Dailley fully explains his treatment plans for us, including relevant treatment options and accurate estimates of cost, and then carries out the agreed upon plans in a friendly, compassionate and highly professional manner. We unreservedly recommend Dr. Dailley and his fine support staff for all one’s dental needs.
