In our warm environment, you will find that our staff is extremely approachable and helpful throughout your entire visit. We are committed to offering our patients the best current treatment options that apply to their situation in a friendly, relaxed environment.
Dr. John Lau received his Bachelor of Science (Honours) in Pharmacology and Toxicology, Masters of Science in Pathology and his Doctor of Dental Surgery from the University of Western Ontario. He has been practicing in Peterborough since 2002, and establised his own practice, Peterborough Smiles Dental Centre in 2009.
Patients who prefer amalgam-free dental fillings will be delighted to know that Peterborough Smiles Dental Centre can work with a variety of restorative materials, including those that are free of mercury or amalgam.

Whether you need something as simple as a filling replaced, want to explore the aesthetic difference that a crown could make on a discolored or damaged tooth, or need more complex procedures like replacement tooth implants or root canal therapy, Peterborough Smiles Dental Centre can work with you to devise a treatment plan aimed at repairing or replacing your natural teeth without the use of amalgams, giving you the healthy and beautiful smile you deserve.
If you've suffered from crooked teeth for long enough, but are put off by the thought of wearing traditional metal braces, Peterborough Smiles Dental Centre has another option that might just work for you: Invisalign invisible braces. Using the most innovative technology in dentistry today, Invisalign uses a series of comfortable, removable, transparent aligners to gradually straighten your teeth.
Gone are the days when tooth trauma and cavities could only be treated with unsightly metal fillings. Today, modern, tooth-colored fillings made of durable resin can be bonded to your teeth for a stronger, more natural-looking effect. Composite fillings are virtually undetectable and require only a single appointment to apply.

I had to have 2 fillings redone. I am SUPER anxious about dental work and Dr. Lau and his staff were all wonderful. They walked me through the parts I wanted to know and worked quickly and efficiently giving me plenty of breaks as needed. I highly recommend this office to anyone looking for amazing dental care.
