As a specialist in Specialty Practice in Oral Medicine & Oral Pathology, Dr. Leong is dedicated to helping patients achieve significant improvements related to their specific and often complex oral health needs. At Mount Sinai Hospital, the focus is on partnering with you towards outcomes such as:

• If an old dental bridge that felt loose, uncomfortable, or was showing signs of wear and tear is proving to be a significant barrier to your daily comfort or confidence, Dr. Leong develops targeted strategies aimed squarely at an impacted tooth being successfully managed or removed, preventing future pain, infection, or damage to other teeth. This careful approach facilitates your ability to once again fully enjoy biting into sandwiches or other challenging foods with complete confidence.
• The path to improved oral wellness, especially when facing recognizing the need for a deep cleaning (scaling and root planing) because it had been a significant time since their last professional hygiene visit, involves working systematically towards feeling confident that their gum health is being actively maintained, preventing future problems. Dr. Leong expertly guides patients through this process so they can once again enjoy life's moments, including their child being able to participate in classroom activities without dental distractions.
• Many patients schedule a consultation with Dr. Leong when they first notice ongoing concerns about bad breath that they believed might be related to a hidden dental infection or persistent gum problem. Through personalized dental care, the goal is to achieve their gums looking pink and healthy again after treatment for gingivitis or early gum disease, enabling them to once again enjoy travelling and trying new cuisines without fear of unexpected dental emergencies without hesitation.
• Patients presenting with their child having a pronounced fear of needles or injections at the dental office, requiring a very patient approach can find lasting relief and achieve the important outcome of experiencing a significant reduction in jaw pain and morning headaches after treatment for teeth grinding (bruxism) under Dr. Leong's experienced care. This frequently allows them to resume maintaining fresh breath, which improves their social and professional interactions without the former limitations or discomfort.

Your specialized treatment plan, developed in consultation with Dr. Leong, will be meticulously designed to address your unique concerns and help you reach your specific objectives within their area of expertise. Dr. Leong is committed to providing the highest standard of specialized care, tailored to your individual needs.

Dr. Leong's practice is located at Mount Sinai Hospital in the Bay Street Corridor (Discovery District) neighborhood of Toronto. The clinic is conveniently located near Chinatown Centre and is accessible via TTC (Subway, Streetcar, Bus). Ample parking is generally available close to the dental office; please observe local signage.

How often should I (or my child) visit Dr. Leong for a check-up and cleaning?

For most patients, preventative check-ups and cleanings are generally recommended every 6 months. However, Dr. Leong will recommend a personalized schedule based on your individual oral health needs, risk factors for cavities or gum disease, and any existing conditions. For example, some patients may need visits every 3-4 months if managing active gum disease or at high caries risk, while others with excellent long-term oral health might have slightly longer intervals. It is crucial to follow Dr. Leong's specific recommendations for optimal oral health.

Are dental X-rays safe, and how often are they needed?

Dental X-rays are very safe, especially modern digital X-rays which use minimal radiation. Protective lead aprons are always used. X-rays are taken only when diagnostically necessary, such as for new patients, to check for decay between teeth, assess bone health, or plan complex treatments. Dr. Leong will determine the frequency based on your individual oral health, risk factors, and dental history, adhering to guidelines like ALARA (As Low As Reasonably Achievable).

Do I need a referral to see a general dentist like Dr. Leong?

Typically, a referral is not required to schedule an appointment with a general dentist. Patients are welcome to contact Mount Sinai Hospital directly to arrange their visit with Dr. Leong.

What should I expect during my first dental visit with Dr. Leong at Mount Sinai Hospital?

At your initial appointment, Dr. Leong and the team at Mount Sinai Hospital will focus on getting to know you and your oral health. Expect to fill out a medical history form, have a discussion about any dental issues or goals you have, followed by a detailed examination of your mouth. Digital X-rays may be taken to get a complete picture. Based on this, Dr. Leong will explain their assessment and any recommended treatments. It's a great time to ask questions.

Do I need a referral from my general dentist to see a dental specialist (e.g., Orthodontist, Periodontist)?

While some dental specialists may accept patients directly, it is often recommended, and sometimes required by the specialist or insurance plans, to have a referral from a general dentist like Dr. Leong. A referral ensures the specialist has relevant background information and that the visit is appropriate. If Dr. Leong identifies a need for specialist care, they will provide a referral to ensure coordinated care. If unsure, check with the specific specialist's office or your insurance provider.

Is dental treatment generally covered by provincial health plans like Ontario Health Insurance Plan (OHIP) in ON?

In Ontario, provincial health plans like OHIP typically do NOT cover most routine or major dental procedures performed in private dental clinics for the general population. Some specific, limited dental surgeries performed in a hospital setting might be covered. Most dental care costs are paid out-of-pocket by patients or through private dental insurance plans (often through employers) or government assistance programs for eligible groups (e.g., children from low-income families, seniors on specific benefits, social assistance recipients). Verify any potential public coverage you might be eligible for and always check your private dental insurance details before starting treatment.

I experience jaw pain, clicking, and headaches. Can Dr. Leong help with TMJ/TMD issues?

Dr. Leong can perform an initial assessment of your jaw pain and related symptoms. Depending on the findings and complexity, they may offer some conservative management advice or provide a referral to a dentist or specialist with advanced training in TMJ disorders if more specialized care is indicated.

If I have a mouth sore, will Dr. Leong (Oral Medicine/Pathology Specialist) always do a biopsy?

Dr. Leong will conduct a thorough clinical examination. A biopsy is a diagnostic tool used if a lesion is suspicious or its nature cannot be determined by examination alone. Not all sores require a biopsy; some may be diagnosed and managed based on clinical appearance and history. Dr. Leong will discuss if a biopsy is recommended for an accurate diagnosis.
