Our History

Dr. William Cheung & Associates traces its roots back to the 1950's, when we began our prevention-focused dental practice in the old Hong Kong and Shanghai Banking Corporation Building in Central, Hong Kong's business district.

Upon completion of his training in the U.S. in 1982, Dr. William Cheung joined the practice established by Dr. Philip Chan and his uncle, the late Dr. Kenneth Chaun. Dr. Chan retired in 1994, and since then Dr. Cheung has expanded the practice into a multi-specialty group practice, bringing together various specialists under one roof in order to best serve your needs.

We are proud to have continually cared for many generations of patients over the past 60 years. At the same time, we also eagerly welcome our new patients to become a part of our legacy, and we trust that you will be satisfied under our care for the years to come.

Our practice is built on referrals, and you can help us continue to build our future!

Our Team

Preventive Dentistry

Periodic oral assessment

Getting regular dental check-ups allows our dentists to monitor your oral condition, and identify and treat problems early. Most people should see a dentist twice a year, but there is some variation, we will recommend an ideal check-up interval for you based on your oral hygiene level and your risk of tooth decay and gum disease, in conjunction with our clinical findings.

Caries risk assessment

The dental equivalent of "individualized medicine" where we consider multiple factors to determine your risk of tooth decay. This allows us to personalize treatment just for you.

Periodontal risk assessment

Similar to the concept of caries risk assessment, we combine our clinical observations with a personalized interview to determine your risk of gum disease. This way we can prescribe you the perfect regimen to keep your gums healthy.

Oral cancer screening

Early detection is key! We examine every patient at every check-up visit for abnormal growths, because the sooner a suspicious area is discovered, the better the chances of isolating and eliminating this disease.

Dietary Counseling

What you eat, and how you eat it, affects not only your physical health but also your oral health as well. Our dentists and hygienist are happy to discuss your eating habits with you and give you some helpful tips on how to protect your teeth and gums and help them stay healthy.

Oral hygiene instructions

As children, one of the first things we learn how to do by ourselves is brushing our teeth. Over time, we each develop our own home care habits, which may not always result in excellent oral hygiene. Let our dentists and hygienist give you a refresher course on the products and techniques you can use to take great care of your teeth and gums at home!

Scaling & polishing

These components of a professional cleaning effectively remove bacterial plaque and tartar from the surfaces of your teeth, resulting in healthier gums and reduced instances of tooth decay.

Topical fluoride application

Once thought to be only beneficial in children and adolescents, the modern concept of preventive dentistry acknowledges that adults at risk of tooth decay can also benefit from periodic fluoride application. Professional application of fluoride has no documented risk of causing fluoride poisoning.

Fissure sealant application

Pits and fissures occur on the chewing surfaces of our back teeth. Sealants are applied over these crevices to prevent food particles from getting trapped, which may result in tooth decay. Sealants have proven to be the most cost-effective method of preventing tooth decay, and can be placed starting from 6 years of age.

Fees & Insurance

Our fees are based on the amount of time necessary to complete a procedure, and the degree of complexity as well as the difficulty of treatment. Therefore we do not have a published fee schedule for the services we provide.

However, we can give you an estimate on your request after we make the diagnosis and propose a treatment plan. Please bear in mind that the original plan may change as treatment proceeds, but we will certainly explain to you why changes are necessary and inform you about the adjusted fee as you desire.

We expect payment as service is rendered. Payment can be made in form of cash, Visa, Master, EPS, CUP, American Express, Apple Pay, Android Pay or Alipay. We are also glad to complete any claim forms so you may be reimbursed directly by your insurance company if you have dental insurance coverage.
