Thuan D.
I highly recommend Dr. So and the team at CV Orthodontics for their outstanding service and care. From my initial consultation to creating a personalized treatment and payment plan, every step was seamless and stress-free.

After visiting several orthodontic offices, I'm glad I chose Dr. So's team. They consistently demonstrated exceptional courtesy and attentiveness to my needs, making me feel valued and supported throughout my journey.

Natacha J.
Dr So’s office is really efficient. I appreciate the text reminders, the self-check in and the welcoming atmosphere. Even though there are a lot of assistants on deck (I am basing this assumption on the youthful appearance of the employees), she always makes a point to avail herself when necessary.

The office is closed on Friday. While inconvenient, I appreciate the commitment to work/life balance.
Response from the owner:Thank you for your kind words! Your vote of confidence in our practice is why we do what we do!
Phuong V.
I recently completed my orthodontic treatment with Dr. So Orthodontic. I wanted to share my experience and why I think Dr. So is an exceptional choice for anyone considering orthodontic treatment.

From the very first consultation, I was impressed by Dr. So’s approach. Orthodontic treatment can feel daunting, but their gentleness and patient care stood out immediately. Dr. So took the time to explain all my options in detail, making sure I understood each step of the process. This level of care and communication was consistent throughout my treatment.

What truly sets Dr. So apart is their profound knowledge and expertise. They're not just about straightening teeth, they take a comprehensive approach to orthodontics, considering facial aesthetics, jaw alignment, and most of all your overall looks. It was clear to me that I was in the hands of a professional who is deeply passionate about delivering the best outcomes for their patients.

My results speak for themselves. I am thrilled with the transformation and the confidence my new smile has given me. But beyond the results, it was the journey that made my experience so positive. Knowing I was in gentle and knowledgeable hands made all the difference.

If you're looking for an orthodontist who combines expert care with a compassionate approach, I highly recommend Dr. So. They have not only transformed my smile but made the entire process a truly positive experience. Thank you, Dr. So, and all of your wonderful staff for the exceptional care and for giving me a smile that I'm proud to show off.
Response from the owner:Thank you so for your amazing review! We are so excited about your new smile and so happy that the journey was a pleasant experience!
L
Dr. So is absolutely amazing! Before deciding on CV Orthodontics, I consulted with a few other places. None of them were as comprehensive as Dr. So. They were just going to straighten my teeth, whereas Dr. So has designed a lovely smile like an artist! She is a consummate professional and warm. I look forward to my monthly visits. I highly recommend her!
-L. Chaney
Response from the owner:Thank you so much for the outstanding review! We love to be part of your journey to a beautiful smile!
Mocha B.
This has been the most phenomenal experience for me. I was sentenced to 2 years of wearing braces and there were ups and downs with getting adjusted, however Dr. So and her amazing team has been really good to me. They reassured me that everything would be fine and I was in good hands. I trusted their judgment and what they suggested would be best for me. The day to get my braces removed was rewarding and my teeth look BOMB! Dr. So did that and I’m so happy with the final results and couldn’t be happier! I would recommend Castro Valley Orthodontics to any and everyone who are in need of braces !
Response from the owner:Thank you so much! Sooooo excited about your beautiful new smile. It was a pleasure to be a part of your braces journey! - Dr So
Paulina Del R.
As a dentist, there is no one else I would trust with my own child's teeth than Dr. So. She is hands down the best!
Response from the owner:Thank you Dr Del Rio! It’s our pleasure to have your wonderful kids in our practice!
oliver L.
Dr. So is super friendly and have many years of experiences.
Response from the owner:Thank you so much for your thoughtful review. We appreciate the positive feedback- it means so much to us. We hope to continue to serve you and your family in the best way possible. Dr. So
Bree S.
The team and Dr. So are amazing. They explain a plan each appointment. Very attentive team.
Response from the owner:We love to hear great reviews about our office. Thank you for the positive review for being such a great patient! We appreciate you!

How can I prepare for an orthodontic visit?
To prepare for an orthodontic visit, gather any relevant dental records, insurance information, and a list of questions. Brush and floss before the appointment, and be ready to discuss your dental history and treatment goals with the orthodontist.
Whats the cost of orthodontic care in Castro Valley?

The frequency may vary based on individual treatment plans and needs. Regular visits help ensure the treatment progresses as planned and address any issues promptly.
What are signs I might need orthodontic treatment?
Signs you might need orthodontic treatment include crooked teeth, difficulty chewing or biting, speech problems, mouth breathing, jaw pain, and shifting teeth. If you notice any of these signs, consult an orthodontist for an evaluation.
Can orthodontic treatment prevent dental issues?
Orthodontic treatment can prevent dental issues by correcting misalignments that lead to problems like tooth decay, gum disease, and jaw pain. Proper alignment improves oral health, making it easier to clean teeth and reducing the risk of future dental issues. Regular orthodontic care can help maintain a healthy smile and prevent potential complications.
What is the best age to start orthodontics?
The best age to start orthodontic treatment is typically between 7 and 14 years old when the child has a mix of baby and permanent teeth. Early intervention can help guide jaw growth and correct bite issues. However, orthodontic treatment can be successful at any age.

Yes, we offer Invisalign as an invisible option for teeth straightening. Invisalign is a clear aligner system that is virtually invisible, comfortable, and removable for easy oral hygiene. It is a popular choice for teens and adults seeking a discreet orthodontic treatment option.
What post-treatment care is necessary after braces?
After braces, post-treatment care is crucial. Here are some essential steps to follow: Wear retainers as instructed by your orthodontist. Maintain good oral hygiene with regular brushing and flossing. Attend follow-up appointments for monitoring. Avoid hard, sticky foods to prevent damage. Continue any recommended exercises or treatments for optimal results.
Can I see orthodontic results in a year?
Orthodontic results can vary, but significant progress is possible within a year, especially with treatments like braces or Invisalign. Consistent compliance with treatment recommendations and good oral hygiene can help achieve visible improvements in alignment and bite correction. Regular check-ups with your orthodontist will track progress and adjust treatment as needed.
How do I maintain oral hygiene with braces?
Maintaining oral hygiene with braces is crucial. Here are some tips: Brush after every meal with a soft-bristled brush. Use a floss threader or interdental brush to clean between brackets. Rinse with mouthwash to reach areas that are hard to brush. Avoid sticky and hard foods that can damage braces. Attend regular check-ups with your orthodontist for adjustments and cleaning.
Are there alternatives to traditional metal braces?
Yes, alternatives to traditional metal braces include Invisalign clear aligners, ceramic braces, lingual braces, and clear braces. Each option offers different benefits and aesthetics to suit individual preferences and treatment needs. It's best to consult with an orthodontist to determine the most suitable option for your orthodontic treatment.
What are the benefits of early orthodontic evaluation?
Early orthodontic evaluation offers numerous benefits, including: Identifying potential issues early Guiding jaw growth and development Creating space for permanent teeth Preventing more severe problems Improving overall oral health
How can orthodontics improve dental function?
Orthodontics can enhance dental function by correcting misalignments, improving bite alignment, and addressing jaw issues. This can lead to better chewing, speaking, and overall oral health. Additionally, orthodontic treatment can alleviate issues like TMJ/TMD, sleep apnea, and speech impediments, enhancing overall dental function and quality of life.
What financing options are available for orthodontics?
Various financing options are available for orthodontic treatment, including payment plans, flexible spending accounts, health savings accounts, and insurance coverage. Additionally, many orthodontic practices offer in-house financing or partner with third-party financing companies to help patients manage the cost of treatment. It's essential to inquire about these options during your initial consultation to find the best solution for your financial situation.
Can orthodontics correct jaw misalignment issues?
Orthodontics can correct jaw misalignment issues through treatments like dentofacial orthopedics and pre-surgical orthodontics. These methods help align the jaws properly, improving function and aesthetics. Consulting with an experienced orthodontist can determine the best approach for individual cases.
Are orthodontic treatments covered by dental insurance?

It's essential to check with your insurance provider to understand the extent of coverage for orthodontic procedures.
What dietary restrictions come with orthodontic braces?
When wearing orthodontic braces, it's essential to avoid hard, sticky, or chewy foods to prevent damage to the braces and teeth. Opt for soft foods, cut fruits and vegetables into small pieces, and avoid sugary snacks to maintain good oral hygiene. Remember to brush and floss regularly to prevent plaque buildup.
How does orthodontic treatment enhance facial aesthetics?
Orthodontic treatment enhances facial aesthetics by improving jaw alignment, correcting bite issues, and creating a harmonious balance between facial features. Straightening teeth can also enhance facial symmetry and overall appearance, leading to a more confident smile and improved facial aesthetics.

An orthodontist specializes in straightening teeth and correcting jaw alignment, while a dentist focuses on overall oral health, including cleanings, fillings, and general dental care. Orthodontists undergo additional training to become experts in orthodontic treatment, offering specialized care for alignment issues and bite problems.
