Dr. Timothy Lee graduated from the University of Toronto, Faculty of Dentistry in 1995. He is licensed with the Royal College of Dental Surgeons of Ontario. Dr. Lee currently practices modern dentistry with a personal touch. It is his belief that good dentistry is best performed when considering the wishes of patients. A lot of time is spent discussing treatment options and approaches before work is initiated. The added benefit is that patient ‘comfort concerns’ are revealed beforehand. These factors all come together to make for a comfortable patient experience.

Why should patients choose you as their provider instead of others in the area?

One of life’s special relationships. It’s something that we take seriously at Streetsville Dental. Here we think long-term, since our patients continue to see us for life-times. We build relationships based on trust, and developed with reliable information and sincere treatment advice.

Which cases do you enjoy treating? Why?

There are many benefits of having healthy teeth and proper jaw alignment. Crooked and crowded teeth are hard to clean and maintain. This can result in tooth decay, worsen gum disease and lead to tooth loss. Other orthodontic problems can contribute to abnormal wear of tooth surfaces, inefficient chewing function, excessive stress on gum tissue and the bone that supports the teeth, or misalignment of the jaw joints. These can lead to chronic headaches and face or neck pain. Orthodontic treatment can be less costly than the additional care required to treat dental problems arising as a result of orthodontic problems. For most people, a beautiful smile is the most obvious benefit of orthodontics. After your braces come off, you’ll feel more confident about your smile and your overall dental health.
