"How much does a 牙套 cost?" - first work out whether you mean braces or a crown

"How much does a 牙套 cost?" - first work out whether you mean braces or a crown

Direct answer: 牙套 names two treatments - the orthodontic appliance that aligns teeth, and the crown that covers one tooth [F18]. The fee items are structured differently and cannot be compared with each other; ask for the diagnosis in writing first [F3·S12].

Scope: This guide is specific to Taiwan's healthcare system (National Health Insurance and Taiwan's Medical Care Act). The passages on fees, statutes and verification routes cite Taiwanese law and Taiwanese authorities; the clinical evidence passages cite international literature, and the two are tagged separately in the fact ledger.

Sorting questions: which one are you asking about

The three questions below are a way of sorting the question that this site has written for readers. They are not a diagnostic tool and not an official classification [F18]:

1. Are you trying to solve "how my teeth are arranged" or "one tooth is damaged"? Straightening teeth and changing the bite means an orthodontic appliance; a tooth with a large defect, or one that has had root canal treatment and which the dentist says needs covering, means a crown.
2. Does the quotation describe repeated adjustment appointments, or making and fitting one unit onto one tooth? The first is closer to an orthodontic course of treatment, the second closer to a crown.
3. What is the diagnosis written on the paperwork? If you cannot tell, ask the institution to write down the diagnosis and the treatment items - Article 81 of Taiwan's Medical Care Act provides that "When treating the patient, the medical care institution shall inform the patient or his/her legal agent, spouse, kin, or interested party of his/her condition, course of treatment, disposition, medication, expected condition, and possible ill effects." [F3·S12]

The two kinds of 牙套 are excluded from Taiwan's National Health Insurance for different reasons, which is itself a useful sorting clue:

• Orthodontics: Article 51, subparagraph 3 of Taiwan's National Health Insurance Act lists "Treatment of drug addiction, cosmetic surgery, non-post-traumatic orthodontic treatment, preventative surgery, artificial reproduction, and gender conversion surgery" among the service items not covered [F5·S9].
• Crowns: subparagraph 11 of the same article lists "Dentures, artificial eyes, spectacles, hearing aids, wheelchairs, canes, and other treatment equipment not required for positive therapy" [F6·S9].

In principle neither is covered, but the basis is a different subparagraph and a different kind of treatment; whether any particular item in an individual case is covered still follows the current rules and review practice of Taiwan's National Health Insurance Administration [F5·S9][F6·S9]. It follows that the two quotations cannot be read against each other [F18].

A. Crowns: what makes up the fee

Whether it is done at all, and why that changes the cost

A crown is a fixed restoration cemented over what remains of the tooth after that remaining tooth structure has been prepared down into a core. Whether to do one depends on how much tooth is left - a point the Cochrane systematic review states directly in its background: the choice of restoration depends on the amount of remaining tooth, and may influence durability and cost [F8·S2].

As for "does a root-treated tooth always need a crown", the randomised evidence is not sufficient to settle it. That 2015 update of the Cochrane review found only one eligible trial, judged to be at high risk of bias; the authors concluded that there is insufficient evidence to assess the effects of crowns compared with conventional fillings, and that until more evidence appears clinical decisions should rest on the clinician's judgement and the individual patient's circumstances and preferences [F8·S2]. The same review records that for its secondary outcomes - patient satisfaction, recurrence of caries, periodontal health status and costs - no evidence was available at all [F8·S2]. So neither "a crown works out cheaper in the end" nor "skipping the crown saves money" comes from this line of evidence.

What the quotation should itemise

The breakdown below is an editorial framework written by this site so that two quotations can be lined up item by item [F18]:

• Assessment and preparatory procedures: examination, imaging, tooth preparation; where needed, root canal treatment, a post and core, or crown lengthening as separate procedures. Ask item by item which are included and which are charged separately.
• The crown itself and the laboratory work: material and fabrication method (metal-ceramic, veneered or monolithic all-ceramic) carry different cost structures.
• Temporary restoration and definitive fitting: whether both sit inside the same quotation.
• Try-in, occlusal adjustment and review appointments: how many are included, what happens beyond that, and what the conditions for remaking are.

What the literature says about materials

A systematic review and meta-analysis published in 2026, with a search window of 2014 to 2024, included 64 studies reporting on 3,509 metal-ceramic and 8,051 all-ceramic single crowns, and estimated five-year survival rates across materials and designs ranging from 90.4% to 98.5% (monolithic lithium-disilicate reinforced glass-ceramic 98.5%, metal-ceramic 97.1%, feldspathic or silica-based ceramic 90.4%); the same review reports significantly fewer ceramic fractures and chipping for monolithic designs than for veneered ones [F7·S1].

These are statistical estimates for a study population, not a prediction for your tooth, and not a quality indicator for any clinic. Which material and design suit you varies from person to person and must be assessed by a dentist against your bite, the site and your appearance requirements. The full cost breakdown for the crown branch is in the fixed-denture cost card in the internal citation chain.

B. Orthodontic appliances: what makes up the fee

Treatment length: the literature reports a population average, not your schedule

Orthodontics runs over a span of time, and the fee structure is usually tied to time and to the number of appointments. A 2016 systematic review included 25 studies after screening (20 randomised controlled trials and 5 controlled clinical trials); across the 22 studies that could be pooled, the mean treatment duration with fixed appliances was estimated at 19.9 months (95% CI 19.58-20.22), and across the 5 studies that recorded it the mean number of required visits was 17.81 [F9·S3]. The authors concluded that, based on prospective studies carried out in university settings, comprehensive orthodontic treatment on average requires less than two years to complete [F9·S3].

Note the limit on where that figure comes from: it is drawn from prospective studies in university settings and cannot be treated as a promise of duration for any individual [F9·S3].

Does the type of appliance change how long treatment takes? A 2024 systematic review included 10 studies and concluded that in mild to moderate crowding cases the treatment duration with clear aligners is similar to that with fixed appliances - but it graded this as low evidence under GRADE, and no meta-analysis was performed because inconsistency was too high [F10·S4]. So "which one is faster" is not currently a question with high-grade evidence behind it, and the choice depends on your own situation and treatment plan.

The end of active treatment is not the end: ask how retention is charged

After the appliance comes off, teeth tend to move back towards their original positions, so a retention phase follows; retention is achieved with fixed or removable retainers that provide stability [F11·S5]. The Cochrane systematic review updated in 2023 included 47 studies with 4,377 participants and concluded that the evidence is low to very low certainty, so no firm conclusion can be drawn about any one approach to retention over another; the authors add that more high-quality studies are needed that follow tooth stability for at least two years and that measure how long retainers last and what side effects they cause [F11·S5].

For fees this means: ask up front whether retainers, retention-phase appointments, and the handling of a broken or lost retainer are inside the orthodontic quotation [F18]. This site gives no general answer on how long a retainer should be worn; that is for your dentist to decide case by case.

What the quotation should itemise

Again, an editorial framework written by this site [F18]:

• Initial assessment and orthodontic records: examination, imaging, models or intra-oral scans, treatment plan.
• The appliance itself: appliance type and treatment plan differ, so the way items are split may differ.
• Scheduled adjustments during treatment: whether each adjustment is inside the headline figure, and what happens if more are needed than planned.
• Additional procedures during treatment: for example extractions, temporary anchorage devices, replacement of attachments, repair of a damaged appliance.
• Retention phase: making retainers, retention-phase appointments, conditions for remaking.

Applies to both: what Taiwanese fee rules actually say

• Fee standards are approved locally; there is no nationwide price list: Article 21 of Taiwan's Medical Care Act provides that "Standards for medical fees charged by the medical care institution shall be determined by the municipal or county(city)competent authority." [F1·S10] What is actually charged should be checked against the rules of the locality where you are treated and against the institution's written itemisation.
• You are entitled to a receipt you can read: Article 22 provides that "Receipts shall be made by medical care institutions for medical fees charged, which shall clearly state the item(s)and fee(s)." and that "Medical fees charged by medical care institutions shall not violate or exceed the standard for the fees, nor shall medical institutions charge for items without authorization." [F2·S11]
• You are entitled to be told before treatment: the duty to inform in Article 81 covers the condition, course of treatment, disposition, medication, expected condition and possible ill effects [F3·S12].

In other words, when two quotations differ a great deal, the usual reason is two different lists of items. That does not make every difference self-explanatory: charges still have to comply with the standard approved by the competent authority of the city or county where you are treated, and only an item-by-item comparison means anything [F1·S10][F2·S11].

Before your appointment: eight questions to ask about the quotation

1. What is the formal diagnosis and treatment name on the quotation - orthodontics, or prosthodontic restoration? [F3·S12]
2. Which steps does this quotation cover, and which items are charged separately?
3. Are the initial assessment, imaging and orthodontic records already included?
4. Is the appliance or the laboratory work itemised separately? What material and design? [F7·S1]
5. How many review and adjustment appointments are included? What is charged beyond that, or if the appliance breaks?
6. If the treatment plan changes, how will additional costs be explained in advance? [F3·S12]
7. For orthodontics, is the retention phase (retainers plus retention-phase appointments) included? [F11·S5]
8. Will the receipt state the fee items and the amounts? [F2·S11]

How to check a quotation you have been given (things you can actually do)

• Look up the fee standard approved by the health bureau of the city or county where you are treated: the verified example is the schedule published by the Taipei City Department of Health, 「臺北市醫療機構牙科收費標準表」 (approved 1090117 in the ROC calendar); the same material also appears on Taiwan's open data platform as the dataset 「臺北市醫療收費標準」 (dataset 121913) [F15·S14][F15·S15]. Other cities and counties publish their own; look up the one where you are actually treated.
• Taiwan's NHIA "medical device price comparison" site does not cover dentistry: on 2026-08-06 this site re-checked both of its search tracks in a browser. The category list on the differential-payment track ran to 12 entries and the surgery-and-procedure category list on the device-fee track ran to 8 entries; the visible text of neither page contained the character 牙 (tooth) [F16·S16]. If you see advice along the lines of "look up the price of a 牙套 on the NHIA comparison site", note that as of our test date it is not there.
• Where a check is impossible, go back to the paperwork: the absence of an item from public data does not mean an official price exists for it; the written quotation and the receipt from the institution remain the thing to reconcile item by item [F2·S11][F18].

Risk factors (what to know before treatment)

Each kind of 牙套 has its own indications, risks and contraindications, and must be assessed by a dentist:

• A crown requires irreversible removal of tooth structure: the choice of restoration depends on the amount of remaining tooth and may influence durability and cost [F8·S2]; different materials fail in different ways in terms of fracture and chipping [F7·S1].
• The evidence gap around crowns: for crowns versus conventional fillings on root-filled teeth the randomised evidence is insufficient, and there is no evidence at all on cost, recurrence of caries or periodontal status [F8·S2].
• Fixed appliances and white spot lesions (demineralised lesions): a 2025 systematic review and meta-analysis of 57 studies and 9,101 patients estimated a pooled prevalence of white spot lesions among orthodontic patients of 55.06% and a pooled incidence of 34.2%; among patients who had not been treated the pooled prevalence was 29.1% (also a prevalence, so comparable with the first figure), and prevalence rose with longer treatment duration [F12·S6]. A Cochrane review likewise states in its background that early dental decay or demineralised lesions can appear on teeth during fixed brace treatment [F13·S7]. Preventive measures, including professional fluoride application, are for your dentist to decide case by case; this site gives no product or concentration advice.
• Orthodontics and root resorption: a 2022 systematic review and meta-analysis states that external apical root resorption is a serious complication that should be avoided during orthodontic treatment, and that the evidence suggests it is similar regardless of the technique used; the same authors warn that these conclusions should be treated with caution because the certainty of the evidence is low [F14·S8].
• Teeth tend to move back after treatment: relapse tendency after the appliance is removed is why retention is part of the course of treatment - but which approach to retention is better rests on low to very low certainty evidence [F11·S5].
• Limits of the evidence level: the survival rates, prevalence figures and treatment durations cited in this card are all population-level estimates and cannot be used to infer any individual's outcome. The actual treatment method and its results vary from person to person and must be assessed by a dentist [F7·S1][F9·S3].
