Restorative Dentistry in Istanbul

Restorative dentistry is the repair work: fillings, inlays, onlays, crowns and bridges. It deals with teeth damaged by decay, fracture or wear, and its purpose is to get a tooth working again and keep it working for as long as possible.

It overlaps with cosmetic dentistry, and the two are constantly confused — deliberately, in a good deal of advertising. The distinction that matters is this: restorative work is decided by what has been lost, cosmetic work by what you want to look different. This page is about the first. If a tooth is sound and you simply dislike its shape or colour, the conservative route is composite bonding, not a crown.

What is restorative dentistry, and can it be done in a short trip?

Direct answer

Restorative dentistry repairs teeth damaged by decay, fracture or wear, using fillings, inlays, onlays, crowns and bridges. Its purpose is function and longevity rather than appearance. Most restorative work can be completed within a short trip, and the important question is not which material is used but how much healthy tooth has to be removed.

The ladder that decides everything

Every restorative decision sits on a ladder, and the rungs differ mainly in how much sound tooth is removed to place them.

Direct filling — material placed and shaped in the tooth in a single appointment. Least tooth removed.
Inlay or onlay — a laboratory-made restoration bonded into or over the prepared area. More tooth removed than a filling, less than a crown; an onlay can cover weakened cusps without encircling the whole tooth.
Crown — the tooth is reduced on all surfaces and a cap is fitted over it. Most tooth removed.
Extraction and replacement — when there is not enough tooth left to restore.

You cannot climb back down this ladder. A tooth that has been crowned cannot be un-crowned; the structure is gone. That single fact should govern how you read every quote you receive, and it is the reason the rest of this page is written the way it is.

What the evidence says about how long restorations last

Direct composite fillings. A meta-analysis based on individual participant data from 12 longitudinal studies with at least five years of follow-up analysed 2,816 posterior resin composite restorations, of which 569 failed during the observation period. The main reasons for failure were caries and fracture, and the risk of failure was significantly higher in people at high caries risk and in restorations involving a greater number of surfaces (Opdam, van de Sande, Bronkhorst, Cenci, Bottenberg, Pallesen, Gaengler, Lindberg, Huysmans & van Dijken, Journal of Dental Research, October 2014, PMID 25048250).

The clinically useful part of that finding is often skipped: your caries risk and the size of the restoration predict failure better than the brand of material. A clinic that changes your material but not the reason your fillings keep failing has solved nothing.

Composite compared with amalgam. In a randomised clinical trial, 472 participants aged 8 to 12 were randomly assigned to receive either amalgam or resin-based composite restorations in posterior teeth. Of 1,748 restorations followed for up to seven years, 10.1% failed: survival was 94.4% for amalgam and 85.5% for composite, secondary caries was the main reason for failure in both, and the risk of secondary caries was 3.5 times greater in the composite group, with the difference accentuated in large restorations and those involving more than three surfaces (Bernardo, Luis, Martin, Leroux, Rue, Leitão & DeRouen, Journal of the American Dental Association, June 2007, PMID 17545266).

That study was carried out in children, and we are labelling it as such rather than quietly presenting it as an adult figure. Its relevance to you is the pattern rather than the percentage: the larger the cavity, the more the material choice matters.

Inlays, onlays and overlays. A systematic review and meta-analysis of 21 clinical studies with follow-up beyond five years reported estimated five-year survival of 86% for resin (n = 129), 90% for feldspathic porcelain (n = 1,048) and 92% for glass ceramic (n = 2,218), and at ten years 75% for resin (n = 115), 91% for feldspathic porcelain (n = 1,829) and 89% for glass ceramic (n = 1,075). Failures were mostly fractures (6.2%), endodontic problems (3%), secondary caries (1.7%) and debonding (0.9%) (Naik, Jain, Rao & Naik, Journal of Conservative Dentistry, July–August 2022, PMID 36187858).

Crowns. A systematic review of survival and complication rates of tooth-supported single crowns reported five-year survival of 94.7% for metal-ceramic crowns (95% CI 94.1–96.9%), 96.6% for leucite or lithium-disilicate ceramic (95% CI 94.9–96.7%), 94.6% for glass-infiltrated alumina (95% CI 92.7–96%), 96% for densely sintered alumina (95% CI 93.8–97.5%) and 92.1% for zirconia (95% CI 82.8–95.6%) (Sailer, Makarov, Thoma, Zwahlen & Pjetursson, Dental Materials, June 2015, PMID 25842099).

Rebuilding a root-treated tooth. In an epidemiological study of 1,462,936 teeth in 1,126,288 patients across 50 US states followed for eight years, 97% of teeth were retained after initial non-surgical root canal treatment — and among the teeth that were extracted, 85% had no full coronal coverage(Salehrabi & Rotstein, Journal of Endodontics, December 2004, PMID 15564861). If a back tooth has been root-treated, how it is rebuilt is not a detail. See root canal treatment.

Who is a good candidate

Restorative treatment abroad tends to go well when:

The work is defined and finite — named teeth, named restorations, on a written plan.
Your gums are healthy or have been treated first.
Decay risk is being addressed as well as repaired: diet, hygiene, fluoride, and the reason the last restorations failed.
You can stay long enough for laboratory-made work to be fitted and adjusted.
Nothing on the plan is being done to teeth that are currently sound.

Who is NOT a good candidate

Restorative treatment is the wrong plan, or the wrong time, if:

You have active untreated gum disease. A crown on a tooth losing its bone support is money spent on the wrong problem. Treat the foundation first — see gum disease treatment.
You are in pain from an infected tooth. Get that assessed first; the restoration comes after, not instead.
There is too little sound tooth left. Restoring an unrestorable tooth produces something that fails later and costs more than removing it would have. See oral and maxillofacial surgery and dental implants.
The plan involves crowning teeth that are sound. This is the central objection to a great deal of dental tourism, and we are not going to soften it.

You should think much harder if:

The quote covers a set number of units — eight, ten, twenty — rather than a list of named teeth. Healthy mouths do not come in package sizes.
No one has explained why a filling or onlay will not do. That explanation should be specific to your tooth, and it should be in writing.
You grind your teeth and nobody has mentioned it. Bruxism breaks restorations. A plan that ignores it will need redoing, and a night guard costs a fraction of a remake.
Only one material is ever offered, to everyone. Materials have different strengths and different failure patterns; a clinic where every patient receives the same one is describing its workflow, not your tooth.

Comparison compiled by DentVisit, August 2026. Survival figures describe study populations in the cited peer-reviewed sources, not individual outcomes.

Where we will argue against ourselves — twice.

First, on zirconia. Zirconia crowns are the flagship product of Turkish dental packages, and the review cited above did not rank them first: five-year survival was 92.1% (95% CI 82.8–95.6%), the lowest of the crown types compared, and the authors concluded that “zirconia-based SCs should not be considered as primary option due to their high incidence of technical problems”. Two honest caveats belong with that sentence. It reflects studies available up to that review’s publication in 2015, and materials and techniques have continued to develop since — but we are not going to claim newer generations perform better, because we have not verified a source that shows it. Treat it as a question to put to any clinic proposing zirconia for your case: why this material for this tooth, and what does the current evidence say?

At DentVisit: zirconia crowns are among the crown materials offered, alongside metal-ceramic and lithium-disilicate options. That does not change the survival figures or the caution above — it means the question above is the one to ask before agreeing to this material for your tooth.

Second, on the whole category. A large amount of restorative work sold to dental travellers is not restorative at all. It is cosmetic work performed by cutting down sound teeth, described in restorative language because that sounds necessary. If your front teeth are healthy and you want them straighter, whiter or more even, crowns are the most destructive way to achieve it. Look at composite bonding or orthodontics first, and read cosmetic dentistry for how those options compare. We would rather you had less treatment here than lost tooth structure you can never get back.

Why restorative quotes are so hard to compare

“A crown” is not one product. The materials in the table above have different survival profiles. A quote that does not name the material cannot be compared with one that does.
Number of surfaces. A one-surface filling and a four-surface filling are different amounts of work with different expected lifespans.
Whether a core build-up or post is included where a tooth is heavily broken down.
Whether the tooth needs root canal treatment first, and whether that is inside the quote.
Per unit or per tooth for bridges. A three-unit bridge replaces one tooth using two others. Quotes are sometimes given per unit, which makes them look lower.
Whether adjustment and review are included, and whether they fall inside your travel dates.

Ask for a plan with tooth numbers, the material for each restoration and what is included. Then two quotes become comparable.

A realistic trip to Istanbul

The sequence below is the clinical pathway, not a holiday itinerary. Your own schedule is confirmed after your case is reviewed.

Fillings only — typically 2–3 working days

Day	What happens
Day 1	Examination, radiographs, written treatment plan. Fillings started under local anaesthetic.
Day 2	Remaining fillings completed. Bite checked and adjusted.
Day 3	Review, polishing, prevention advice, departure.

Crowns, onlays or a bridge — typically 5–7 working days

Day	What happens
Day 1	Examination, radiographs, written treatment plan. Any decay removed and foundations built where needed.
Day 2	Teeth prepared, digital scan or impression, shade selected, temporary restorations fitted.
Day 3–4	Laboratory fabrication. Little or no chair time.
Day 5	Try-in, fit check, bite and shade assessed before final cementation.
Day 6	Final fit and cementation. Bite adjusted.
Day 7	Review after a day of eating on the new work, final adjustment, aftercare briefing.

Sequence published by DentVisit, August 2026. Timings are typical clinical ranges and are confirmed individually after case review.

Four practical rules for booking flights:

Leave at least one clear working day between final fitting and your flight. New restorations frequently need a small bite adjustment once you have eaten with them. That is minutes in Istanbul and another trip from Dublin.
Do not fly home with temporary crownsand a plan to “sort the finals later”. Temporaries are not designed for months of use, and the tooth underneath is vulnerable.
Agree the shade in daylight, before cementation, and say so if it is not right. Once a crown is cemented, changing the colour means remaking it.
Ask what happens if a restoration needs adjusting after you get home, and get the answer in writing before you book.

Before you travel, you can send your X-ray to DentVisit by WhatsApp for a free pre-assessment and case review, and a detailed written treatment plan is provided before any commitment — so you know which teeth are proposed for treatment, and how many days it takes, before you book anything. The clinic is equipped with intraoral scanning and digital imaging; see digital dentistry for what that does and does not change.

What happens when you fly home

What is true:NHS England’s policy, published on 4 November 2024, states that patients who paid for dental treatment privately in the UK or abroad and later need NHS care “are entitled to access NHS dental care for assessment and evaluation to stabilise their condition”, but that “self-funded care that the NHS would not routinely fund would not usually be offered or replaced once stabilisation has been achieved”. The policy also states that “it is expected that patients would initially seek support from their self-funded dental care provider, who should be responsible for any post-treatment clinical issues within a reasonable timeframe”.

In plain terms: if a crown comes off or a tooth becomes painful, the NHS will make you safe. It will not routinely replace self-funded restorations. Your first call is the clinic that placed them.

One aftercare detail specific to restorative work: restorations fail at the margins, quietly, and usually without pain until decay is well established. That is what routine check-ups and bitewing radiographs are for. Restorative treatment abroad without a check-up arrangement at home is unfinished business.

What DentVisit provides: a free pre-assessment and case review from your X-ray before you travel, a detailed written treatment plan before any commitment, English-speaking support, and post-treatment remote follow-up.

What you should arrange yourself, before you travel:

A registered dentist at home for routine check-ups and radiographs.
A written record of materials and shades for every restoration. A dentist repairing or matching that work later will need it — ask for it before you fly.
Copies of your radiographs, before and after.
Clarity on who to contact and how, outside clinic hours. DentVisit is open Monday to Friday 10:00–18:00 and Saturday 10:00–17:00, Turkish time (UTC+3), and is closed on Sundays.
Written answers to the questions the General Dental Council advises patients to ask before going abroad, including “Who will be carrying out my treatment and what qualifications do they have?”, “Is the work guaranteed for a certain period of time?”, “What aftercare do you provide?” and “If there are complications and I need further treatment, is this included in the initial cost?”

When to worry after restorative treatment

Sensitivity to cold for a few days, and tenderness while the bite settles, are expected. The following are not, and should be assessed:

A bite that feels high. Common after new work, quick to adjust, and damaging if left — it can crack the restoration or inflame the tooth beneath.
Sensitivity that increases after the first week, or that changes to lingering pain after hot or cold.
Pain on biting on one particular spot, which can indicate a crack or a high contact.
A crown, onlay or filling that comes off. Keep it, keep the tooth clean, and arrange to be seen — the exposed tooth is vulnerable.
Food packing persistently between two teeth where it did not before. This usually means a contact point needs correcting, and left alone it causes decay and gum inflammation.
A dark line, chip or roughness at the margin of a restoration.
Swelling of the gum or face, with fever — seek urgent local care the same day.

Frequently asked questions

How long do fillings last?

There is no single number. In a meta-analysis of 2,816 posterior composite restorations from studies with at least five years of follow-up, 569 failed, mainly through caries and fracture, and failure risk was significantly higher in people at high caries risk and in restorations covering more surfaces (Opdam et al., 2014). Your risk profile matters more than the brand.

Do I need a crown, or would a filling do?

It depends on how much sound tooth remains and whether the cusps are weakened. The ladder runs filling, then inlay or onlay, then crown, and each rung removes more tooth. Ask specifically why the lower option will not work for your tooth, and ask for that reasoning in writing before anything is prepared.

Are white fillings as good as amalgam?

In a randomised trial in 472 children aged 8 to 12, seven-year survival was 94.4% for amalgam and 85.5% for composite, with secondary caries risk 3.5 times greater in the composite group and the difference widening in large, multi-surface restorations (Bernardo et al., 2007). For small and moderate cavities the practical difference is far smaller.

Are zirconia crowns the best option?

Not automatically. In a systematic review of tooth-supported single crowns, five-year survival was 92.1% for zirconia against 96.6% for leucite or lithium-disilicate ceramic and 94.7% for metal-ceramic, and the authors advised against zirconia as a primary option because of technical complications (Sailer et al., 2015). Ask why a specific material is proposed for your tooth.

How many days do I need in Istanbul?

Typically two to three working days for fillings alone, or five to seven where crowns, onlays or a bridge are being made, because laboratory stages and a fitting appointment are involved. Always leave one clear working day between final cementation and your flight home for bite adjustment.

Do I need a crown after root canal treatment?

Usually for back teeth. In a study of 1,462,936 root-treated teeth followed for eight years, 97% were retained — and among those that were extracted, 85% had no full coronal coverage (Salehrabi & Rotstein, 2004). Front teeth with minimal tissue loss are sometimes restored with a filling. Your plan should specify which.

What is the difference between an inlay, an onlay and a crown?

An inlay sits within the prepared cavity, an onlay also covers one or more weakened cusps, and a crown encircles the whole tooth. The clinical difference is how much sound tooth is removed. In one review, ceramic partial-coverage restorations reached 90–92% five-year survival, so an onlay is often a genuine alternative to crowning.

Should I have all my old fillings replaced?

Not as a routine. Every replacement removes a little more tooth, and a sound restoration with no decay and no fracture is doing its job. Replacement is indicated for decay at the margin, fracture, persistent food packing or a failed seal. Be cautious about any plan that proposes replacing everything at once.

Is restorative treatment available on the NHS?

Yes. Unlike purely cosmetic work, restorative treatment addresses decay, damage and function, so it is provided on the basis of clinical need under NHS band charges. The barrier most patients describe is access and waiting times rather than eligibility. Check current NHS guidance for your circumstances, as availability varies between practices.

Can restorative work fix the appearance of my front teeth?

It can, but that is usually the wrong reason to choose it. Crowning sound front teeth removes structure permanently for a cosmetic result that composite bonding can often achieve without cutting healthy tooth. Where a front tooth is genuinely broken down or heavily filled, a crown or onlay may be the correct restorative answer.

I grind my teeth. Does that change the plan?

It should. Grinding is a recognised cause of restoration fracture, and a plan that ignores it tends to need redoing. Expect a discussion about a night guard, about the material chosen and about how your bite is designed. If nobody raises it, raise it yourself before treatment starts.

Next steps

If teeth are broken, decayed, worn or heavily filled, the starting point is radiographs and a written plan naming each tooth and the restoration proposed for it — not a package of units.

If a tooth is painful or has been flagged for root canal treatment, read root canal treatment first. If it cannot be saved, see oral and maxillofacial surgery and then dental implants. If your gums bleed, gum disease treatment comes before any restoration. And if the teeth themselves are healthy and what you actually want is a better-looking smile, start with composite bonding — the most conservative option on the shelf — or read cosmetic dentistry for the wider comparison.

You can send your X-ray by WhatsApp for a free pre-assessment before you book anything: contact DentVisit.
