Excellent teeth, expensive smiles

A cavity of mine became a root canal. The price surprised me and I hesitated. Then came the crown, and I hesitated again. Eventually the tooth was lost and the conversation moved to an implant.

Price did not cause that on its own. Teeth fail for reasons of their own. But price was in the room at every step, and it pushed each decision in the same direction, which was later.

I thought about that sequence again on holiday in Spain, doing what a lot of Swiss visitors quietly do, which is looking at other people's teeth. Spend time in Italy, Spain, Greece or Portugal and you come away with the impression that people there have remarkably good teeth.

The obvious explanation would be better dental health. The data says close to the opposite.

The Swiss have very good teeth

Dentistry has a standard measure of population dental health: the DMFT index, which counts how many permanent teeth in twelve-year-olds are decayed, missing or filled.

By that measure Switzerland sits near the top of the European table. Surveys in the canton of Zurich, run to the same standard since 1964, put average DMFT in twelve-year-olds at around one. A European meta-analysis of twelve-year-olds finds significantly more caries in southern and eastern Europe, in lower-income countries and in countries with higher unemployment, with national averages running as high as seven.

Roughly one damaged tooth, against seven at the European high end.

That gap is a prevention story, not a genetic one. Zurich began adding fluoride to table salt in 1955, the first programme of its kind anywhere, and other cantons followed. Fluoride toothpaste arrived in the 1970s. School dentistry, supervised brushing and hygiene did the rest. Caries in twelve-year-olds in the canton of Zurich fell by more than eighty percent over four decades.

So there is a paradox. The Swiss have the healthier teeth. Southern Europeans make more of theirs.

The supply side

Switzerland has around 82 dentists per 100,000 inhabitants, counting those with a cantonal authorisation to practise under their own professional responsibility at the end of 2024. Greece reports 134 licensed to practise and Portugal 121. Cyprus has the highest density of practising dentists in the EU, at 132. Ireland sits at the other end with 46.

Greece reports around 60 percent more dentists per head than Switzerland.

The registers are not perfectly comparable. Some count dentists who have retired or emigrated, and the official concepts of licensed, professionally active and practising do not measure the same thing. Even Switzerland has more than one answer: an FSO measure put the country at 51 per 100,000 in 2017, against the 82 above. That is not a statistical error. The two figures count different things. The pattern survives the caveats anyway.

Several southern and eastern European countries built that density through relatively open university admission and an expansion of private dental schools. Dentistry is an attractive destination in economies with fewer well-paid professional routes, because it combines status, a portable qualification, self-employment and the chance to own a business. Studies of dental students in those countries find professional image among the leading reasons to enrol.

The result in several markets is oversupply. Younger dentists work part-time, or struggle to make a practice viable.

That matters, because dentistry is a business as well as a profession. Put a lot of dentists into a market with modest household incomes, thin public dental coverage and falling caries rates, and they have to compete for patients.

The natural place to compete is aesthetics. Whitening, bonding, aligners, veneers and smile makeovers are treatments people choose to buy when nothing hurts. Competition also pushes the prices down.

So the first explanation for the southern European smile is mundane. More dentists, competing for fewer euros.

Teeth are a class marker

Straight, white teeth are already a marker of social advantage. The research is strongest in North America, where they have been linked to perceptions of attractiveness, competence, health and success. Sociologists describe teeth as one of the ways class becomes physically embodied and put on display.

In that sense teeth work like clothes. People dress for the world they want to enter, not only the one they already occupy. Almost nobody straightens or whitens their teeth in order to look upper middle class. They want to look polished, healthy, professional, attractive. Those ideals are themselves class-coded.

The United States is furthest down this road. Spain and Italy are probably ahead of Switzerland, helped by lower prices for cosmetic work. Switzerland is catching up, and younger Swiss are noticeably more willing than their parents to have their teeth corrected, and more likely to believe that good teeth help in a job interview.

The Swiss inversion

Switzerland is excellent at prevention and leaves ordinary adult dentistry almost entirely to the patient. Compulsory health insurance covers dental treatment only in narrow circumstances.

There is a logic to that. Prevention worked, and premiums are already high. But prices change behaviour, which is where my root canal comes back.

A cheap problem becomes an expensive one. The expense makes the patient more inclined to postpone the next step. The delay makes the eventual work more complicated, which makes the bill larger again. High prices do not only make dental treatment expensive. Sometimes they make the treatment that eventually happens more expensive.

Aesthetics takes it a step further. Alignment, whitening, bonding and veneers are paid out of pocket without exception. Two people with equally healthy teeth end up with visibly different smiles, because one can spend several thousand francs without noticing and the other cannot.

What looks like a beauty trend is also an income story. And it becomes more visible as dental health improves, not less. Once severe decay is rare, what separates one smile from another is alignment, colour, proportion and restorative work.

The price difference is mostly not in the tooth

The large price gaps between Switzerland and the rest of Europe are less mysterious than they look.

Good clinics in Budapest, Barcelona, Milan, Athens or Kraków buy from the same global manufacturers as Swiss dentists. Straumann is headquartered in Basel. Ivoclar is in Schaan, just over the Liechtenstein border. The ceramic in a veneer does not know whether the chair is in Zurich or Budapest.

What changes is labour, rent, operating costs, competition and what the local market will bear.

That arbitrage is legitimate. Using a lower price to justify treatment that is not needed is not.

What is actually worth doing

One principle covers most of it: maximum visible improvement for minimum biological cost.

Prevention comes first. Do not trade healthy teeth for cosmetic dentistry.

After that, whitening buys a large visual change and removes no tooth structure. Alignment addresses the crowding and unevenness behind most supposedly bad smiles. Hygiene, gum health and proportion matter as much as colour. Composite bonding handles small gaps, chips and shape corrections, and it can be undone.

Veneers come later.

A conservatively prepared veneer for the right indication is one thing. Grinding down healthy teeth and covering them with crowns to manufacture a uniform white smile is another. That is not a cheaper version of good cosmetic dentistry. It is a more destructive procedure, and it is the single thing most worth refusing, at home or abroad.

A clinic that proposes extensive irreversible work without diagnostics, a written treatment plan and a serious conversation about alternatives has already told you what you need to know.

Not a gap in the system

Switzerland has no secret to learn from the south. It has spent decades producing some of the healthiest teeth in Europe, and it should say so more often.

What southern and eastern Europe have is a different dental economy. More dentists, lower labour costs, harder competition, and a large market for work intended to improve how teeth look rather than to save them.

In Switzerland, access to that work is allocated substantially through purchasing power. Someone who can comfortably pay CHF 2’000 approaches a dental problem differently from someone for whom CHF 2’000 is a serious household event. That is usually described as a gap in the Swiss healthcare system. It is more accurate to call it a decision. Ordinary adult dentistry was left outside compulsory insurance, and the distribution that follows is the predictable consequence, not an oversight.

Every affluent society decides how much of that competition to soften. Several European countries socialised more of the cost of healthcare and made equal access an explicit political aim. Switzerland has generally left more responsibility, and therefore more differentiation, with the individual.

Which leaves an unusual combination. Excellent teeth, expensive dentistry, and a smile in which income remains surprisingly easy to read.
