What happens at a first orthodontic assessment

Many people put off booking because they do not know what they are walking into, or worry they will be sold something on the spot. A first orthodontic assessment normally covers five things:

1. Understanding what you most want to change, whether that is appearance or function;
2. Examining tooth alignment, the bite, the gums and the relationship between the upper and lower jaws;
3. Taking orthodontic diagnostic records: intra-oral and facial photographs, an intra-oral scan, plus a panoramic radiograph (OPG) and a lateral cephalometric radiograph. Both radiographs are standard for orthodontic assessment, since they show root position, unerupted teeth and the front-to-back and vertical relationship of the jaws;
4. An initial explanation of fixed braces, clear aligners, whether extractions are likely, and any other workable options;
5. The expected treatment duration, the main risks, and the fee range.

Some complex cases need the records and radiographs analysed before a formal treatment plan can be given. Where that applies we say so at the visit itself, rather than letting you expect a final plan the same day.

Why the treatment plan has to be built around you

It is easy to assume orthodontics means wearing an appliance, so the cheapest appliance will do. In practice, a plan that has not properly accounted for gum health, root and bone condition and the bite raises the risk of the treatment drifting off course and of complications. A responsible plan assesses the following first:

Fixed braces or clear aligners

Both are tools for delivering force to teeth. Neither one determines the outcome; the treatment plan does. Where they genuinely differ is in daily use:

Both can be the right tool. The question is not which one is more advanced, but which one is better suited to finishing your treatment plan. That judgement follows a clinical examination, rather than choosing a brand first and making the case fit it.

How teeth actually move, and why it takes this long

Teeth are not fixed rigidly into bone. Routine cases can first be assessed by the general dental team at Home Dental Centre. Where clinical needs indicate further care in this area, Dr. David K. Leung (Specialist in Orthodontics), Dr. Richard Ho (Dentist) and Dr. Wilson Man (Dentist) at the centre provide the relevant treatment; the treating dentist is arranged according to clinical needs and the dentists on duty. Where a case involves more than one area of dentistry, dentists from different areas at the centre can jointly develop a combined treatment plan, without the patient needing a referral elsewhere. An appliance applies light, continuous force; the bone around the tooth remodels, resorbing on one side and forming on the other, and the tooth migrates through bone towards its planned position.

Because this is a biological process that depends on bone remodelling step by step, there is a safe rate of movement. More force does not mean faster:

1. Excessive force or movement that is too rapid does not shorten treatment. It raises the risk of complications.
2. Properly run treatment therefore takes time, generally 12 to 24 months depending on the case.
3. Speed is the wrong first criterion for choosing a treatment plan. Suitability is the right one.

What do you most want improved? Different goals mean different plans

There is no single standard for appearance. Some people care most about the front teeth being straight, some about the profile, and some only want to chew properly. So the most important step before treatment starts is stating the goal clearly. Where the goal stays vague, treatment can run smoothly and still not match what you had in mind.

1. Often, simply improving alignment achieves the appearance you were after, without committing to more complex, higher-risk movements.
2. Conversely, forcing high-risk movements in pursuit of a maximal change, such as over-expanding the arch or over-retracting the front teeth, can cost you gum recession or root resorption, neither of which is reversible.
3. Doing less, safely and stably, often serves you better over time. The clinician's job is not to push for the largest possible change, but to work with you to balance appearance, function, stability and risk.

Limits and risks: some movements should not be forced

Being clear about what cannot be done matters as much as explaining what can.

1. Arch expansion in adults is limited. In children and adolescents the mid-palatal suture has not fully closed, so an appliance can achieve genuine skeletal expansion. In adults the suture is usually more mature, so a conventional tooth-borne expander achieves comparatively little skeletal widening, and part of the change may come mainly from teeth tipping outwards, which relapses easily and increases the risk of gum recession. Where a larger skeletal change is needed, bone-anchored expansion or a surgical approach may have to be considered; whether either is feasible depends on age, skeletal pattern and gum condition.
2. There is a limit to how far teeth can move. Moving teeth too far or too quickly can cause gum recession and root resorption, in which roots become shorter, and rarely the tooth's nerve can lose vitality. These are not reversible.
3. Adults can still achieve very good results, but the plan has to be built differently: tighter goals, more conservative movement and closer monitoring.

None of this means braces are unsafe. Most cases complete uneventfully given accurate diagnosis, sensible force levels, good cleaning and regular monitoring. The point is that the plan has to respect each person's biological limits.

Regular review visits, so drift is caught early

Orthodontics is a dynamic process running over one to two years. Teeth do not always respond exactly as first predicted, which is why treatment needs continuous monitoring and adjustment as it goes.

1. Reviews are generally every four to eight weeks, with progress checked against the treatment plan.
2. Adjusting force, wear pattern or appliance as soon as drift is spotted is usually easier than dealing with it late in treatment, and reduces the chance of replanning or extending the case.
3. Movement that is too fast and movement that is too slow are both problems: too fast can damage roots and the periodontium, too slow points to a problem with force levels or with wear.
4. Repeatedly missing reviews, or abandoning treatment part-way, drags the case out and leaves alignment and bite unfinished, sometimes with gum or root problems that were avoidable. If treatment has been interrupted, it should be reassessed by a Specialist in Orthodontics as soon as possible rather than simply stopping wear or discarding the appliance.

Debonding is not the finish line: retainers decide whether the result holds

After treatment, teeth tend to drift back towards where they started. That is the natural behaviour of periodontal fibres and bite forces, not a sign that treatment was done badly. The retainer's job is to hold teeth in their new position while the surrounding tissues settle.

1. Retainers may be removable, or a wire bonded behind the teeth, and are chosen to suit your case. Sometimes both are used.
2. How and how long they are worn depends on the case: usually more intensively at first, then tapering.
3. If wear stops altogether, teeth can gradually relapse. Crowding returning to the lower front teeth is the most common pattern.
4. Retainers can break, distort or get lost. Contact the clinic to have one replaced as soon as that happens, rather than waiting for the next review.

Our formal quotation states whether retainers are included in the treatment fee, and what a replacement costs, so there is no unexpected charge once treatment finishes.

Children: what Phase I early treatment actually is

Treating children is not the same as treating adults, because a child's skeleton is still growing, and that is a window adults do not have. A first orthodontic assessment at around age 7 is generally advised. That does not mean treatment starts at 7; it means a clinician can judge whether anything needs early intervention.

What Phase I commonly addresses

• Crossbite: the upper and lower teeth meet the wrong way round, which affects jaw development if left.
• Habits: thumb sucking, tongue thrusting and similar habits that affect how the arches develop.
• Severe crowding or lack of space: managing space early to guide adult teeth into position.
• Growth guidance for skeletal problems (growth modification): depending on the problem, this may involve a functional appliance, an expander, or headgear (an extra-oral traction appliance), used during the growth period to guide the upper and lower jaws into a more favourable position and reduce the chance of needing more complex treatment, or even orthognathic surgery, later on. This is not available once growth is complete.

But Phase I is not needed by every child. Most children do not need early intervention, and a full assessment once the adult teeth are through is sufficient. Treating early when it is not needed simply adds a burden for the child. Whether Phase I is indicated has to be a clinical judgement, and that is exactly the point of the age 7 assessment: intervene early where it helps, and simply monitor where it does not.

How to verify a Specialist in Orthodontics in Hong Kong yourself

Only a dentist listed under the Orthodontics category of the Specialist Register maintained by the Dental Council of Hong Kong may hold themselves out as a Specialist in Orthodontics. Specialists must complete accredited specialist training and the associated professional assessments before being entered on the register.

You can check this yourself rather than relying on what a clinic tells you:

1. Go to the Dental Council of Hong Kong website and open the Specialist Register.
2. Search the dentist's name under the Orthodontics category.
3. A dentist not listed there cannot describe themselves as a Specialist in Orthodontics, however experienced they may be clinically.

It takes about a minute, and it is the easiest and most useful check you will make in the whole process.

Orthodontic fees

An orthodontic assessment requires both a panoramic (OPG) and a lateral cephalometric radiograph. These are charged separately and are not alternatives to one another. Orthodontic treatment starts from HK$30,000. What you pay depends mainly on how complex the case is, how long it runs, which appliances are needed, and whether other treatment has to be combined with it, rather than on the brand of appliance. An accurate quotation follows a clinical assessment by a Specialist in Orthodontics.

The formal quotation sets out the appliances, the expected treatment range, the review schedule, and whether retainers and other items are included, so that no unexpected charge appears once treatment has started.
