Digital X-ray Technology

With digital x-ray technology, we use computerized equipment and software to capture x-ray images of your mouth and teeth. Digital x-rays have many advantages over traditional dental x-rays:

Our office use low radiation digital x-ray technology to capture clearer images your teeth that Dr. Zheng can view right away. The images can also been immediately shown to you using TV monitor mounted on the ceiling.

Digital x-rays allow Dr. Zheng to see areas of your mouth and teeth that would otherwise not be visible: cavities between the teeth, infections in the roots, odd angles, etc. Problems can be detected and treated earlier before you may be aware of them. If decay and infection go undetected and untreated, they can lead to pain and discomfort as well as more costly and invasive dental treatment.

If you have questions about why x-rays are needed and how often you should have them done, please talk to Dr. Zheng.

Brushing Techniques

Your dental care does not end after your visit. We encourage you to take the steps to maintain your oral hygiene by brushing and flossing regularly.

Brushing at least twice a day helps prevent tooth decay and gum disease. A few techniques can help you maximize the 2-3 minutes it takes to brush:

Oral Health problems and Diseases


Elderly patients, especially those in residential care can decrease the risk of dental disease and other serious health problems by caring for their oral health. Residential staff and family are encouraged to help the patient if need be to take care of his or her teeth and dentures daily. Patients with difficulty controlling hand, arm or should movement can modify their tooth brushes to adapt to their needs using:

To help protect your teeth and gums against oral disease and maintain overall good health, your oral hygiene routine should include:


The ideal time to first see a dentist is when your child's first teeth come in at around 6-12 months. Dental problems start early and it is important to safeguard against problems that can affect the development of your child's mouth such as baby bottle tooth decay, gum disease, teeth irritation, prolonged thumb-sucking, etc.

It is encouraged that you talk to a dentist to learn about what the visit will entail and communicate this to your child so there are no surprises.

Child oral health care tips:


Sealing out dental decay.

While cavity prevention starts with a healthy diet, brushing twice a day, daily flossing, and regular dental checkups, sealants can offer additional protection against tooth decay. Sealants are thin, plastic coatings painted on the chewing surfaces of the back teeth (premolars and molars). This clear, plastic coating bonds into the depressions and grooves (pits and fissures) of the chewing surface effectively sealing out the decay-causing bacteria, and reducing the risk of cavities and tooth decay. Children and teenagers will benefit the most.

Dental Nutrition

A healthy Diet for a healthy smile

Strong teeth need a variety of foods from each of the basic food group including whole grain breads and cereals, fruits and vegetables, lean meats or alternatives, and dairy products.

Essential vitamins and minerals in particular, calcium and phosphorus, and vitamin D are needed for strong teeth and bones, as well as vitamins A and C for healthy gums.

While everybody knows that eating sweets is bad for your teeth, what you may not know is that the amount of sweet food you eat is not as important as the length of time your teeth exposed to sweets. This means that you should avoid eating sticky sweets like toffee or hard candies like mints, because they stay in your mouth longer. It also means that eating sweet snacks between meals is much worse than with a meal because at mealtime, the increased flow of saliva helps protect your teeth by washing sugars away. Choose something without sugar nuts and seeds, peanut butter, cheese, plain yogurt, or popcorn for your between meal-snacks and save your sweets for mealtimes.

New Technology

CEREC 3DTM Technology

We're very proud to offer you CEREC 3DTM, the latest generation of CEREC 3DTM, the world's most advanced dental restoration system. CEREC 3DTM (Ceramic REConstruction) allows us to manufacture lifelike porcelain crowns, veneer, inlays, and filling right in our office. Previously these types of tooth restorations required at least two appointments.

CEREC 3DTM uses Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) technology that allows us to obtain a full 360°perspective of your mouth, take an accurate three dimensional picture of the damaged tooth, then transfer it to a color computer screen. No need to take impressions moulds!

The 3D CAD/CAM program images are very realistic and allow Dr. Zheng to design a piece perfectly fitted to the natural tooth and surrounding teeth. Together with the CAM program, CEREC 3DTM technology allows us to precisely mill the restoration so we can bond it to your teeth with a perfect fit.

We use strong ceramic material that is matched to your tooth colour, is translucent like natural enamel and biocompatible. It's also unaffected by heat and cold so you can enjoy hot and cold foods without sensitivity.
