Dr H C Leong Dental Surgeon LLP is a solo general dental practice located at Clarke Quay Central in Singapore, at the heart of historic Singapore along the Singapore River, between Chinatown, the Civic District and the Financial District. The practice offers a comprehensive range of dental services in a cozy, private environment, and describes itself as focused on building long-term relationships with patients through a holistic, whole-of-life approach to oral health.
Core services include wisdom tooth care, root canal (endodontic) treatment, preventive dentistry, restorative treatment for missing or broken teeth (including implants, bridges and dentures), tooth whitening, and orthodontics (braces). For root canal treatment specifically, Dr Leong uses a Cone Beam CT scan and microscope for a comprehensive examination before proceeding, and the practice notes that not every damaged tooth can be saved — badly broken or vertically split teeth beneath the gum margin may instead require extraction or surgery.
When root canal treatment does proceed, it's carried out under local anaesthetic, with a rubber dam used to isolate the tooth from saliva and bacteria. Canals are cleaned and shaped using nickel-titanium files and rotary instruments, with an apex locator used for precise measurement, before the canals are sealed with a combination of MTA root canal cement and warm Gutta Percha. A dental crown is often recommended afterwards to protect the tooth and complete what the practice calls the "coronal seal." The full process typically takes a minimum of two visits of about an hour each, with molars often requiring more time due to their additional canals.
The practice is open Monday to Friday and Saturdays, and patients can reach Dr Leong directly by phone, SMS, WhatsApp or email.
Dr H C Leong Dental Surgeon LLP is a solo general dental practice located at Clarke Quay Central, in the historic heart of Singapore along the Singapore River, between Chinatown, the Civic District and the Financial District. The practice describes its approach as holistic and whole-of-life, with an emphasis on building long-term relationships with patients rather than one-off transactional visits, all within a cozy, private office setting.
The practice covers the core areas of general dentistry: wisdom tooth assessment and treatment, root canal (endodontic) therapy, preventive dentistry, restorative treatment for missing or damaged teeth, tooth whitening, and orthodontics. Preventive care spans professional oral hygiene maintenance and gum treatment, fissure sealants, and guidance on regular checkups, while restorative options include dental implants, bridges, and dentures for patients dealing with broken or missing teeth. The practice also offers dedicated guidance for children's dentistry and oral health during pregnancy.
One of the practice's more detailed offerings is root canal (endodontic) treatment, used when decay, trauma or wear allows bacteria to infect the pulp — the soft tissue of nerves, blood vessels and connective tissue at the centre of a tooth. Left untreated, this infection can spread to the bone supporting the tooth, causing sharp or throbbing toothache, swelling, bad breath, sensitivity and fever.
Not every damaged tooth can be saved. Before proceeding, Dr Leong carries out a comprehensive examination using a Cone Beam CT scan and microscope. If a tooth is too badly broken or has a vertical fracture extending beneath the gum margin, it may need extraction or surgery instead of root canal treatment.
When treatment does go ahead, it's performed under local anaesthetic, with a rubber dam placed around the tooth to isolate it from saliva and bacteria and improve visibility. An opening is made to access the pulp chamber, and the root canals are cleaned and shaped using fine nickel-titanium files and rotary instruments, with an apex locator used to precisely measure each canal — typically the most time-consuming part of the procedure. A calcium hydroxide medicament is placed to address any residual bacteria, and the patient is also given antibiotics. The canals are then sealed using a combination of MTA (Mineral Trioxide Aggregate) root canal cement and warm Gutta Percha, before the upper part of the tooth is rebuilt with a resin or glass ionomer filling material.
A dental crown is often recommended after root canal treatment to protect the tooth, prevent fracturing, and maintain what the practice calls a "coronal seal" against bacterial infiltration — an important factor in the treatment's long-term success. The full process, from the start of treatment through to crown placement, typically takes a minimum of two visits of about an hour each, with molars often requiring extra time due to their additional canals. It's worth noting that root canal treatment itself is not Medisave claimable, unlike related procedures such as root end surgery (apicoectomy).
