Apples are one of the most delicious fruits out there. The minute you pick one up you can't help but want to sink your teeth in it immediately. But when you pick up that shiny, delicious apple and finally take a bite, the worst happens. CRACK. Wait, what was that? Did I just crack my tooth? This is a classic example of a dental emergency, and they rarely happen at a convenient time.
Dr. James Kostas and his friendly team at Complete Dental Care invite you to experience comfortable, caring, and complete dentistry at our Burlington office. We offer comprehensive preventive, cosmetic, and restorative dentistry options, including Six Month Smiles, teeth whitening, porcelain veneers, and periodontal therapy.

Dr. Kostas has been an awesome dentist. I have searched for dentists for a few years going to Gentle Dental and a couple of other ones. They always seemed to try to pressure me into getting everything done at once. Dr. Kostas has been very supportive in building a plan that suits my needs both for my teeth but also financially. I've recommended a few of my friends to him and figured this would be another way to recommend people.

After seeing the same dentist for over 40 years, it was difficult to put our trust in someone new. Our dentist retired, and my wife and I found Dr. Kostas and his staff. Simply AMAZING. Now we look forward to our next visit.

It is an ideal place to care for your teeth. I have been going for more than 20 years and I never had a dental service problem due to their exceptional dental service. The staff is professional, courteous, and most of all competent, and provide an amazing service. Dr. Kostas is an excellent dentist and I strongly recommend that you contact him for dental care.

Just called to get information about Cosmetic Gum Contouring. Essentially a procedure where they trim your gums to show more tooth if you have a lot of gum tissue ruining your smile. This is something that is listed directly on their website under the services that they offer, right under Cosmetic Services. Key note. Cosmetic.
The receptionist spoke to me like I said the moon was made of cheese. And that "she never had someone just reach out for this service before" She kept talking about referrals and other irrelevant information to what is just a cosmetic procedure.
It is a very common procedure

Dr. Kostas and his staff are all so very caring and always putting your comfort and any anxiety at ease. Throughout cleanings or any procedures, they are always making sure you are comfortable and relaxed. The attention to detail on everything from appointments to any tiny feeling on your teeth is impressive. I have always been stressed about the dentist and they make me feel at ease every time.

Dr. Kostas and his team have been consistently caring and responsive over the many years our family has been going to Complete Dental. I want to thank Dr. Kostas for proving to us once again that he cares. My daughter is attending college in Pennsylvania and had a dental issue she was concerned about. She needed advise on what to do. Dr. Kostas called her back that evening, listened to her concern, gave her advice and eased her mind. You are the best!

Dear Dr. Kostas, Gilda, Nancy, Julie, Kelly and the entire CDC Team of Professionals. If social media allowed for ten stars as the highest positive rating that is what I would give to your dental practice. THANK YOU! I’ve been a patient of Dr. Kostas since 2013. I wish I had taken a picture of my teeth then, but I would have been too… embarrassed to share that. At that time, I delayed seeing a dentist for over 13-years, so by the time I ended up in Dr. Kostas chair you can imagine how unsightly my smile was and the challenges he was facing. If you saw my dental x-ray images, double

I have been coming to Dr. Kosta for over 15 years. As a dentist-phobic person, I can honestly say there's no other dentist I would trust with my teeth. I have had consistent, excellent dental care...Dr. K is thorough, compassionate, and he really listens!

Was not there, but had a bad experience with their patient paid amount. Be sure to check your insurance summary. It is fine that they collect in advance, but they should also adjust if the insurance come through with a different ppa then what they originally told the service person. Not sure if bad communication or what, but this problem seems to… be getting resolved. Read your insurance payment summary when you get it. Saves a lot of headaches. Attorney General said they should have rebilled and did not, never should have charged me and they did. They disagree and therefore no refund. I
