Everyone was wonderful! Dr. Koo is literally the only dentist I've ever actually liked!Maryann H.
My wife & I had our teeth cleaning yesterday & Linda, our Hygienists, did an excellent job. She really took the time & effort to do it right. Also, the staff gave my family a really warm welcome even the kids enjoyed it. Great atmosphere, loved it! Highly recommend this place. Danny N
Great, friendly and prompt service. The front office staff was very helpful and professional. Dr. Koo provided excellent care for my fillings. My wife also had her teeth cleaned and the dental hygienist was very thorough and careful. I would definitely recommend MacArthur Park Dentistry to anyone needing dental care.Andrew Y
I have been going to Dr. Koo for about 2 years now and have had nothing but great experiences there. He knows what he is doing and makes you feel that he cares about your dental health. He is NOT cocky and arrogant and is the most helpful when it comes to dental questions. Highly recommended. Plus if you keep your teeth healthy and come to appointments on time you get free professional whitening!!Justin L
Dr. Koo and his staff are very friendly, pleasant, and professional. No complaints and always great care. My wife and I are both regular patients here. The location is convenient next to the renovated Kroger on MacArthur. We do recommend Dr. Koo to our friends and family when asked. For a long time, Dr. Koo kept insisting I get my wisdom teeth removed even though I had not experienced any pain. Then, BAM! Right before Christmas 2014, the pain suddenly appeared. I had been warned! Thankfully, Dr. Koo was able to recommend me to a colleague for oral surgery in Plano.Thomas L
After moving too far away from my childhood dentist and a couple of bad dentist offices I decided to give Dr. Koo and his staff a try. Not only are the staff friendly and tentative to my needs, but Dr. Koo is an amazing and thorough doctor. I have done pretty well with my teeth and have always considered braces. Although, I have been told it wasn't needed the option of clear correct was provided and I have been ecstatic with the results, so far. I used to live in Irving and have since moved to McKinney and choose to travel to the best dental experience I have had. Thank you so much to Dr. Koo and his staff...Highly recommended.Calvin M.
It was a pleasure meeting Emily she showed a great welcome upon entering the office of course everyone is always so friendly.That's why I don't mind traveling from Fort Worth.Wanda E.
Dr Koo and his staff are amazing team. I've been a patient of Dr. Koo for 15 years because he caring, friendly and professional. I've always been exceptionally pleased with his staff because they've ALWAYS been caring and friendly....Thank you !Thomas R.
Hannah at the front desk greeted me promptly and warmly and also did a commendable job in explaining my financial options. Linda was friendly, knowledgeable and efficient. I believe that Dr. Koo demonstrated a genuine personal interest by explaining what he thought was the best treatment and procedure for me. Go MacArthur Park Dentistry Team!Randolph J.
My everyone in my family is a patient of Dr. Koo - including my 3 year old. We are greeted by name at each visit, never have to wait, and they are especially great with kids ( my little one actually loves going to the dentist). The entire staff is AMAZING. We've moved and we still keep Dr. Koo as our dentist. Every step is explained and you are given honest advice and information.Dena P.

F.A.Q. Frequently Asked Questions

What is periodontal disease and how can I prevent it?

Periodontal disease is an infection of the teeth, gums and the bones surrounding the teeth, and it’s the leading cause of adult tooth loss. It is caused by the accumulation of plaque, the sticky film of food and bacteria that forms constantly on your teeth. Diagnosis of periodontal disease begins with a thorough examination. If we find periodontal disease, we’ll talk with you about treatment options and proper home care to minimize bone loss and restore the health of your gums.

I get anxious about going to the dentist. What can I do?

We can offer you some choices to make you feel more comfortable during your appointment. Nitrous oxide, sometimes known as “laughing gas” is a safe and effective option, providing a calming effect that allows you to be more relaxed during your dental procedure. And you can still drive home when you’re done! Another option is oral conscious sedation. It’s a relaxing choice for patients who get anxious for any reason, such as sensitive teeth, a severe gag response or difficulty getting numb with local anesthesia.

Do you accept insurance?

Yes, we accept most major dental insurance plans. Please contact our office at 972-831-9600 to confirm whether we are able to accept your insurance.

I need a crown restoration, but my busy week makes it difficult to have multiple dental appointments. Is there a better way to schedule my visit?

MacArthur Park Dentistry has a state-of-the-art solution for you, CEREC CAD/CAM. This extremely accurate computer-aided design and manufacturing technology allows us to custom-fabricate and place strong, tooth-colored restorations, crowns and veneers right in our office and all in just one appointment! Contact us to learn more about this breakthrough treatment option.

My teeth need straightening. Is there an alternative to metal braces?

Ask us about Clear Correct, an advanced dental treatment that allows us to straighten teeth without braces. Instead, it involves a series of precisely calibrated, clear aligners that gradually reposition teeth. The aligners are easily removable for easy brushing and flossing. They are smooth and comfortable so they are less likely to irritate your mouth.
