Patient Success Stories

Hear It From Our Happy Patients.

Nathan L.

I spent about 3 years with Dr. Douglas, Dr. Sean & Co. and have been satisfied after every visit. The appointments were always perfectly scheduled and changes were easy with how flexible they are. The staff were extremely accommodating and often reached out to me first before I even had the chance to reach the front desk. The braces I got are now removed, but even during my time with them, the ease of how they tightened the braces assured that I was in no pain. Now that I have my retainers, I no doubt trust them with my care in the future

Diego Z.

I just finished my 3 year treatment with this office and have nothing but great things to say! My teeth came out great but the patient care is what impressed me the most! Every single appointment and staff member that helped me along my journey was more than outstanding and I always felt I was in good hands. The office itself is very visually appealing and the kindness and authenticity of each employee was heartfelt. Ashley and Hillary were especially helpful today in taking off my braces and making me feel at home. 10/5 stars and I’ll make sure to refer my future friends and family to this office! Thank you once again to this wonderful team

My wife had her braces done here years ago (around 20years) and till this day people still ask her if her teeth are real because of how straight it is and it’s shape evenly. Now my kids go here also. My son started his treatment back in June 2023, he had his 2 bottom teeth and impacted K9 removed before treatment. It only has been close to 2 years and his teeth are looking really good already. We took our daughter in for a consultation yesterday because my wife noticed that she has an underbite and would like to start Phase 1 treatment so it can help correct her jaw and prep her for Phase 2 when she have all of her permanent and molars out. Dr. Douglas Nguyễn & Dr. Sean Truong does GREAT work, transforming people SMILE everyday. Making them feel more confident and most importantly is that when all your teeth are straight you able to use all them. Besides having GREAT, TALENTED Orthodontists here, they also have a GREAT TEAM of workers who are very polite, welcoming, gentle on my kids, and very knowledgeable. Thank you Dr. Douglas Nguyễn, Dr. Sean Truong and your staff members for giving my family such a good experience and a beautiful SMILES that will last a lifetime

I have had the pleasure of knowing Dr .Douglas and Dr. Sean for many years. I am a dentist and my patients are very important to me and I am protective of them and the care they receive. So when I do refer my young and older patients for braces and orthodontic treatment I want to make sure they receive quality care. More importantly, my main concern is that they are treated well with respect in a welcoming and gentle manner. (….and they do report back to me )
Dr Sean and Dr Douglas and the staff are professional and caring. So much so, when the time came for my own children to start treatment, this is where I brought them. So now I can wholeheartedly recommend them as a professional and as a parent.

Darlene D.

Even though I didn’t want to have to wear braces at first, I couldn’t be happier about the results! I get so many compliments on my smile now & I’ve gained so much confidence due to it. The team did an amazing job taking care of my ortho journey. Everyone here is super attentive, caring & knowledgeable about the process from back office to front desk. I’m even a little sad I won’t be seeing the team anymore

I just wanted to express my gratitude towards Dr. Sean, Dr. Douglas, and their welcoming/supportive team members Hillary, Keilyn, and Isabella on my journey getting a better smile. Before I got my braces, I was really insecure about my teeth/smile because I had an overbite but with the help of them I can confidently smile a lot more now and not be afraid to show my teeth. I am really grateful for them. Come here to get a perfect smile.

Braces

We specialize in orthodontic care for both children and adults! At your initial consultation, we will evaluate your dental malocclusion and discuss the best treatment plan for your teeth. We’ll provide you with different treatment options depending on the specific needs of your case.

WHEN TO SEE THE ORTHODONTIST

The American Association of Orthodontists (AAO) recommends that all children have a check-up with an orthodontist specialist no later than age 7. At this time, the bite begins being establish when the first molars erupt (approximately age 6). The incisors or the front teeth have also begun to erupt at this time and problems can be detected such as crowding, habits, deep bites and some jaw discrepancies. Although most kids do not need treatment at this time, a timely evaluation will lead to significant treatment benefits moving forward and the immediate benefit of a parent’s peace of mind. Adolescents and adults with fully developed dentition can seek a consultation from an orthodontist at any time.

INVISALIGN

METAL BRACES

Traditional metal braces consist of standard metal brackets adhered to your teeth with an adhesive and connected by a wire. They require periodic tightening so light pressure can begin to straighten your teeth. They are still the most common used options today.

Like metal braces, clear braces are still adhered to your teeth and still typically require a metal wire. The difference is the material the bracket is made. Clear braces are typically made of ceramic and are stain resistance.

Invisalign treatment consists of clear sets of removable aligners custom fitted to your teeth. You must wear them 20-22 hours a day and change your set of trays at set intervals as your teeth straighten.
