Dentists in Castro Valley, CA

Excellent staff and so close to home. It’s so convenient that I don’t have to drive far. Just got my basic teeth cleaning and they also explain what I need to keep my gums healthy with the right treatment.

I had another positive experience at Bright Now Dental in Castro Valley. I ordered a mouthguard and it seems to be working out really well!
Definitely so far, so good!! 😁

I was pleasantly surprised! 😁 I had a pain-free experience, while taking care of a couple of filling replacements with Dr.Kellie Kang. Everyone was friendly and helpful, including her assistant, Janeth and the receptionists, too.

I was called almost immediately. Everyone was knowledgeable and friendly. Everything went quickly and smoothly.

They are very nice and professional and the work does appear to be a good quality. It is a bit pricey, so I have to mind that.

On time appointment, minimum paperwork, then to business. Very competent doctors and assistants. Caring and attentive to your needs.

Appointment went well. Staff very pleasant.

Great experience with the staffs and Dr Kang. Dr Kang explained clearly the problems I am having with my teeth and provided solutions. Didn't do any push to their recommendation. Feeling comfort to go there.

I found a truly exceptional dental practice! A welcoming staff who remembers you by name and a skilled, compassionate dentist like Dr. Chang can completely transform what’s often seen as a stressful experience into something positive—maybe even enjoyable.

Her passion for dentistry likely puts you at ease, and knowing you’re in capable hands makes all the difference. I know it is rere to hear someone describe a dental visit as a *pleasure*, but I am. I have definitely stumbled upon something special. I will keep smiling (thanks to Dr. Chang’s excellent work)! 😊

Very pleasant staff,very professional.

Everyone was professional & helpful. The Doctor was gentle & explained the procedure well. 😊

First time coming here and had a great experience. I had a cleaning and fillings done. Dr. Kang and all the staff that I interacted with were friendly and helpful.

Very professional and esthetic beautiful

Great dentist and office staff. State of the art equipment, clean office, easy parking. Highly recommend.

Outstanding service! Was able to quickly assess and provide professional advise on our next steps.

Everyone working there was attentive and helpful. Dr. Kang was great. I have anxiety going to the dentist and the level of care I received made me comfortable and less anxious.

Very good, friendly staff and clean facility!

painless, friendly, and efficient

Amazing staff, super patient, understanding, and they had great music! They were able to see us within two days for an urgent matter even being first time patients. I was super nervous as this was my toddler’s first time at the dentist and it was for a tooth extraction. I was also nervous since it wasn’t a pediatric specialty location but our insurance wouldn’t let us go anywhere else. My nerves were gone the second we were greeted. They put on frozen music for my daughter, were very comforting to me as the emotional parent, and made it overall better than I could have imagined. Thank you!

Very thorough, kind receptionist, thorough dentist. It was a pleasure to be serviced by Bright Smile.

This place is amazing. They are very patient with neurodivergent clients. Dr. Kang is great!

how to wait a bit but Dr. Kang is an excellent and experienced Dentist.

The staff are friendly and I like the dentist.

Excellent

Brindaron un servicio excepcional desde que llegue hasta que salí, tuve una emergencia y me dieron una cita el mismo día.

Very helpful and professional.

Team I interacted with @ Bright Now Dental is very knowledgeable about dental needs and dental insurance. Their people skills are phenomenal. The high quality treatment I receive is fantastic.

I was called almost immediately. Everyone was knowledgeable and friendly. Everything went quickly and smoothly.

In this location you feel you are welcome soon you walk inside, they check you in and out out no delay great customer service, experience.

Friendly staff, thorough examination, no high pressure sales for cosmetic procedures. Great location!

I have always experienced thorough and effective care from Dr. Kang at Bright Now. For the past two years especially, I have learned how to better care for my own teeth and gums at 84 yrs!! Yesterday, I also had X-rays, a complete cleaning, and a thorough gum check from the new dental hygienist, Erin; she was unusually gentle yet careful and I'm convinced, thorough. I feel with these two specialists I have excellent dental care. The two receptionists and bookkeepers have gone out of their ways to answer my occasional questions and smoothly refunded monies that had accrued from an unexpected insurance payment. My visit yesterday indicated that I may need a root canal review in the near future, but I know I am and will be in experienced and caring hands on Redwood Road inCastro Valley. I highly recommend that dental office. Ms. Daniel

Staff is friendly and I had a great experience. I went in for a teeth cleaning at 9 am and was back home by 10 am. Quick and easy...

The hygentist Erin in Castro Valley is wonderful. Thank you Erin. ❤️

My experience with this office and staff have been wonderful, from the receptionist up to the dentist and all in between…they are professional and friendly. I am extremely impressed with this office and have nothing but praise to say about my experiences here.
