Turkish teeth ten years on: what a decade does to a mouth of crowns

Ten years after a set of "Turkish teeth", most people still have a working smile, but rarely the same one they flew home with. The crowns themselves are hard-wearing. What changes is everything around them: the gums, the roots, the nerves inside the teeth and the way you bite. As a Turkish dental clinic we would rather you hear this before treatment than after. Here is a realistic picture of a decade with crowns, based on what clinical reviews report and what dentists see.

Why the crown is rarely the weak point

Modern zirconia and E-max crowns are tough. They do not decay, and they resist staining far better than enamel. Systematic reviews of crown and bridge studies, such as the one by Sailer and colleagues in 2015, found that most failures were not the ceramic breaking. They were what dentists call biological problems: decay at the edge, loss of the nerve, gum problems around the tooth.

That is the key idea for the next ten years. A crown is a cap on a living tooth. The tooth under it still ages, still sits in gum and bone, and can still get ill. If you keep that in mind, most of the changes below make sense.

Years one to three: settling in

The first years are usually quiet. Some people notice:

• Sensitivity to cold in the first weeks or months, which usually settles as the teeth calm down after preparation.
• Bite adjustments. A crown that feels slightly high can make a tooth ache when you chew. A small adjustment usually sorts it.
• Gum tenderness where the crown edge sits near or just under the gum, especially if cleaning there is hard at first.

Any tooth that is still sore after a few months, or that aches on its own at night, should be checked. A tooth that has been heavily prepared can sometimes be heading towards nerve problems, and it is better to know early.

Years three to seven: the gum line starts to matter

This is the period when habits show. Gums naturally recede a little with age, and they recede faster with hard brushing or gum disease. When the gum pulls back, two things can happen.

First, you may see the crown edge or a strip of root above it. With older metal-ceramic crowns this showed as a grey or dark line. With full zirconia or E-max the edge is tooth-coloured, but the root above it is often darker than the crown, so a band can still appear. This is mostly a cosmetic issue, but not always.

Second, that exposed edge is where decay likes to start. The NHS explains that tooth decay comes from plaque bacteria turning sugars into acid. The join between crown and tooth is a natural plaque trap, and root surfaces are softer than enamel. Decay here is often hidden under the crown edge until it is fairly advanced, which is why regular check-ups with X-rays matter.

Gum disease is the other big risk. The NHS lists bleeding gums, bad breath and loose teeth as signs. Crowns do not cause gum disease, but they do not protect against it either, and poorly fitting edges make cleaning harder. If you had gum problems before treatment, this decade is when they will come back if they were not properly treated first.

Nerves: the problem you cannot see coming

Every tooth has a pulp at its centre with nerves and blood vessels. Preparing a tooth for a crown, especially a heavy reduction on a healthy tooth, puts that pulp under stress. In some teeth it never fully recovers. Months or years later the nerve dies or becomes infected.

Signs include a tooth that aches without reason, pain on biting, a gum boil, or a tooth that slowly darkens (harder to see under a crown). The NHS explains that root canal treatment removes the infected or dead pulp and seals the tooth. Often this can be done through the crown, leaving it in place. Sometimes the crown has to come off and be remade.

This is one of the hidden costs of crowning teeth that did not need it. The more teeth that are crowned, the more chances there are that one or two will need root canal treatment over a decade. Reviews of crowns and bridges list loss of vitality among the common complications.

Years seven to ten: wear, bite and replacements

By the end of a decade, other changes tend to show:

• Grinding damage. People who clench or grind, often without knowing, can chip ceramic, crack the tooth underneath or loosen a crown. A night guard is the usual protection.
• Uneven wear. Zirconia is very hard. Natural teeth biting against it, or against each other, wear at a different rate, and the bite can shift slightly.
• Colour mismatch. Natural teeth next to the crowns darken a little with age. The crowns do not. A smile that matched on day one can look patchy at year ten.
• Crowns coming loose. Cement can wash out over many years, especially on short or heavily worn teeth.

Most people with a full set of crowns will need some repairs or replacements in this period. Not all of the crowns, and not all at once, but planning for one or two remakes is realistic.

A rough decade at a glance

What keeps a decade of crowns healthy

None of this is a reason to panic. It is a reason to look after crowned teeth with more care than natural ones, not less. The things that make the most difference are simple:

1. Clean the edge. Angle the brush at the gum line and use interdental brushes or floss daily.
2. Keep seeing a dentist. A UK dentist can check your gums and take X-rays to spot edge decay early, wherever the crowns were made.
3. Wear the night guard if you were given one. Grinding is one of the commonest reasons crowns crack.
4. Cut down sugary snacking. How often you eat sugar matters more than how much.
5. Keep your records. The X-rays, the list of materials and the guarantee paperwork save time and money later.

How we plan for year ten at our clinic

We think the best way to avoid problems at ten years is to crown fewer teeth in the first place. Our dentists prefer to keep a healthy tooth rather than crown it, and they will suggest bonding or veneers where those are enough. When crowns are needed, gum health is checked and treated first. We make crowns from zirconia or E-max rather than metal-based porcelain, and you take home copies of your X-rays and scans.

Our written guarantee on crowns and bridges is 5 years, with the conditions set out in our guarantee terms. After that, upkeep is yours to plan for, so we prefer to be honest about it now. A zirconia crown with us is £150 per tooth, which helps if one needs remaking later. You can read how we approach full sets on our full mouth crowns page, and how gum problems are handled before treatment on our gum treatment page.

A good set of crowns can serve you well for many years. The patients who do best at year ten are the ones who were told the truth at year zero and kept up the cleaning in between.
