Routine Exams


Regularly scheduled treatments can help you avoid complicated procedures, save you time and money in the long term. Our hygiene department will provide effective periodontal treatment, sealant, and fluoride treatment for best preventive care.

Composite Fillings


Reasons for Composite Fillings: Chipped, worn or decayed teeth, closing gaps between two teeth. The procedure is usually completed in one appointment. While the tooth is numb, our doctor will remove all decay required, then thoroughly cleaned and prepared for the new filling to be placed. If the decay is near the nerve of the tooth, a special medication is applied for added protection. The composite filling will then be placed, polished, and your original tooth shape is then restored.

Dental Implants


Dental implants are artificial roots commonly made out of titanium, that are surgically inserted into the bone. The crown is then secured to the implants, providing a natural look, and restores the patient’s smile. These titanium implants are very strong and durable, only requiring occasional re-tightening from normal wear.

Laser Therapy


Periodontal laser therapy, we use a dental laser to access and remove the inflamed gum tissue from around the root of the tooth. When the infected tissue is removed and the root is exposed, the root scaling begins. This involves scraping off the calculus and plaque built up below the gumline and around the root. The dentist then smooths the root with instruments to remove any rough spots that might attract bacteria and cause future infections. The area between the gum and the root can then regenerate during the healing process.

Root Canal Therapy


Symptoms for root canal: sensitivity to hot and cold, an abscess on the gums, severe tooth pain, swelling or tenderness

When decay has reached the tooth pulp or infection has developed inside the tooth or at the root tip, a root canal procedure is needed to save the tooth. Many patients believe that removing a problem tooth is the ultimate solution, without realizing that pulling a tooth will end up being more costly due to the problems caused on the adjacent tooth.

Teeth Whitening


Tooth whitening is a simple, non-invasive dental treatment performed to lighten the colour of tooth enamel. It naturally enhances the beauty of your smile.

We offer very effective teeth whitening procedures, including a selection of home whitening products and chairside whitening. With either method, teeth are typically 6 to 8 shades lighter after the treatment.

Phenomenal, quick service, with super friendly staff. Cleaned my teeth, took care of my insurance and all that with no problems. Would recommend.

Johannes Rebane

I've been here recently for a cleaning and some other work. I found the staff to be very knowledgeable and caring. Dr Dao is friendly and really cares for my well-being. I had a small chip in my front tooth and he took a look and told me not to do anything, I appreciated the honesty, he basically told me that he could fix it, but he couldn't guarantee that it would stay forever, he also mentioned that if I really wanted to get it fixed, he had to drill a bigger hole so that he could make the filling material hold better. No one has ever taken the time to explain it to me like that. I will be coming back for sure!!

I recently went through a difficult process of removing a wisdom tooth. The attention was excellent and very professional. They always explained to me the whole procedure before performing it and I did not suffer any pain at all. Excellent service I recommend it !!
