Dr Chang Fu-Gui has been a senior dental surgeon in private practice in Singapore since 2003, working across general, restorative and cosmetic dentistry, with a particular interest in implants and the quieter problem of bite and tooth wear.
A BDS graduate of the University of Hong Kong and a Fellow of the Royal Australasian College of Dental Surgeons, he has built more than twenty years of practice on a single principle: person first, teeth second.
Dr Chang is a second-generation Chinese-Sri Lankan dentist who grew up, quite literally, inside the profession. His paternal grandfather, part of a small post-war Chinese diaspora in Sri Lanka, made dentures by trade, and both his parents went on to graduate from the Faculty of Dental Surgery in Sri Lanka. Dentistry, in his words, was not so much a career he chose as the air he grew up breathing.
He read dentistry at the University of Hong Kong, graduating in 2003 with the PPDH Board of Governors Prize. He moved to Singapore the same year and was mentored by Dr William Chong, who gave him his first job, taught him implant dentistry hands-on, and instilled habits, including the photographic documentation of every case, that he still relies on twenty years later. He was admitted a Fellow of the Royal Australasian College of Dental Surgeons in 2007.
He travels periodically to the Kois Center, Seattle, whose philosophy of holistic, risk-based care has shaped his practice more than any other single influence. His work centres on general, cosmetic and restorative dentistry and dental implants, alongside the quieter problem of bite and tooth wear, which he finds more common in adult patients than most realise.
For anxious patients, the work begins with trust. Most carry a previous bad experience they may not even mention, and they need to know it will not be repeated.
Outside the practice, he lives in Singapore with his wife, also a dentist, and their two children. He plays golf, cooks for the family, and went down the sourdough rabbit hole during Covid.
Every patient carries an individual risk profile. They deserve to be understood, not treated in cookie-cutter fashion. The profession can get hyper-focused on technical skill at the expense of the bigger picture: managing the person's oral environment so disease doesn't keep returning.
"For anxious patients, the work begins with trust. Most carry a previous bad experience they may not even mention. They need to know I won't repeat it."
Dr Chang practises the full range of general dentistry. Within that range, three areas have absorbed most of his continuing-education hours and most of his clinical interest.
Porcelain crowns, veneers, smile makeovers, professional whitening, and the conservative resin work that often quietly precedes them. His instinct here is conservative: function and biomechanics before appearance, and a reluctance to grind down a tooth that does not need it.
From single-tooth replacement to multi-unit cases. He plans implants with the same risk-first approach he applies to the rest of his work. Bone, gum biotype, bite forces, parafunction, and long-term maintenance are all considered before the surgical day. Where an implant is not the right answer, he says so plainly, and discusses bridges, partial dentures, or no replacement at all as legitimate options.
Among the most underdiagnosed problems in adult dentistry, in his view. Patients arrive with short, chipping teeth and assume they are aging. Often they are grinding, sometimes for years, sometimes in patterns linked to airway issues during sleep. He treats the symptoms with night guards and restoration of worn surfaces, and the cause through occlusal analysis and referral when sleep-disordered breathing is suspected. The order matters. His training at the Kois Center, Seattle, in holistic, risk-based care shapes how he reads these cases: find and manage the underlying cause, not just the worn surface.

In Singapore, a single titanium dental implant typically ranges from around SGD 3,500 to SGD 6,500 per tooth, depending on the implant system, whether bone grafting is required, and the type of final crown. The full process usually spans three to six months: implant placement, a healing period for osseointegration, then the final crown.
Complex cases involving bone grafting or sinus lifts can extend the timeline. At consultation, Dr Chang will assess your bone, bite and health history to give you a specific plan and cost.
A veneer is a thin porcelain shell bonded to the front of a tooth. A crown wraps around the entire tooth. Veneers are usually preferred when the tooth is structurally sound and the goal is cosmetic, correcting shape, colour, or minor alignment. Crowns are indicated when a tooth is heavily restored, root-canal-treated, fractured, or badly worn, where structural protection is as important as appearance.
For a smile makeover, the answer is usually "a mix": each tooth is assessed individually. Which one is right depends on the condition of the tooth, your bite, and how much healthy enamel remains.
Yes. Night-time grinding (bruxism) and morning jaw pain often point to a combination of clenching, bite imbalance, stress, or airway issues. Treatment usually starts with a custom-fitted night guard to protect the teeth and reduce joint strain, along with bite assessment and, where helpful, adjustment.
In longer-standing cases, worn-down teeth may need restoration to rebuild height and function. Dr Chang approaches grinding-related issues as part of a wider risk profile rather than a single symptom to suppress.
Short, chipping teeth are commonly a sign of tooth wear: grinding, clenching, acid erosion, or a combination. Over years, enamel thins and edges break down, which can affect bite, appearance, and function.
Rebuilding worn teeth is a planned process. Understanding the cause first, then restoring shape and length using composite, veneers, or crowns depending on severity. Night-time protection is almost always part of the plan so the same cycle doesn't repeat on the new teeth.
Professionally supervised whitening is generally considered safe for healthy teeth when carried out at appropriate concentrations and intervals. The main side effect is short-term sensitivity, which usually settles.
Options include in-chair whitening for faster, supervised results and take-home trays for gradual lightening. What's less ideal is over-the-counter or unsupervised whitening on teeth with untreated decay, cracked fillings, or gum disease. The bleaching agent can aggravate the underlying issue.
Invisalign in Singapore typically ranges from around SGD 4,500 to SGD 9,500, depending on case complexity. Treatment begins with a 3D scan and a planned tooth-by-tooth movement sequence. You wear each aligner set 20 to 22 hours a day and change trays every one to two weeks.
Most adult cases take between 9 and 24 months, depending on complexity, followed by retainers to hold the result. Simpler cases finish faster; complex crowding or bite correction extend the timeline.
Morning jaw pain is most often linked to night-time clenching or grinding. The muscles have been working while you sleep. It can also involve the temporomandibular joint (TMJ), bite imbalance, or airway-related behaviours like mouth breathing and sleep-disordered breathing.
Diagnosis usually starts with a clinical examination of the teeth, muscles, and joint, plus questions about sleep and stress. Treatment depends on the cause: night guards, bite adjustment, restoration of worn teeth, or referral for airway assessment where appropriate.
