Crowns in your 20s and 30s: the case for starting conservative

A lot of people looking at crowns now are in their twenties and thirties. They have seen smiles online, they have teeth they are not happy with, and a full set of crowns looks like the fastest fix. Some of them really need crowns. Many do not. The difference matters more at 25 than at 65, for one simple reason: time. A crown is not a one-off purchase. It starts a cycle of maintenance on that tooth that lasts the rest of your life.

A crown is permanent, even though the crown itself is not

To fit a crown, the tooth is reduced on every side. Laboratory work on front teeth found that full crown preparations removed about 63% to 72% of the visible tooth by weight, compared with roughly 3% to 30% for veneers (Edelhoff and Sorensen, 2002). That shaped tooth cannot go back to how it was. It will need a crown, or something like it, for as long as you keep it.

The crown, though, will wear out at some point. So the real question is not "how long does a crown last?" but "how many crowns will this tooth need between now and old age, and what happens to the tooth each time?"

What long-term studies show

Short-term figures for crowns look very good. A large systematic review estimated five-year survival of around 95% to 97% for most metal-ceramic and glass-ceramic single crowns (Sailer and colleagues, 2015). Over five years, most crowns are fine.

The picture changes over decades. A Belgian study followed more than 1,000 crowns for 18 years and estimated survival at 78%. Decay was the most common reason for failure, followed by gum disease, and patients who started with poorer gum health were several times more likely to lose a crown (De Backer and colleagues, 2007). A Norwegian study that followed crowned teeth for 25 years found clinical problems on about a third of them, with decay the main cause, and for teeth that still had a live nerve, pulp problems as well. Its estimate was that 83% of crowned teeth with a live nerve stayed free of pulp problems at 25 years, which also means about one in six did not (Valderhaug and colleagues, 1997).

A Scottish X-ray survey adds to that. Of crowned teeth that had a live nerve, about 19% showed signs of disease at the root tip, and the authors concluded that crown preparation itself can damage the pulp (Saunders and Saunders, 1998).

None of this makes crowns a bad treatment. It means that if you start at 25, you should expect some of those teeth to need new crowns, and some to need root canal treatment, during your lifetime.

Why each replacement costs a little more

When a crown is replaced, the old one is cut off, any decay at the edge is removed, and the tooth is reshaped for the new one. Often that means a little more tooth goes each time. If a nerve dies, root canal treatment follows, sometimes with a post. After several rounds, some teeth reach the point where there is not enough left to hold a crown, and the next step is extraction and an implant or bridge.

That chain is slow. It can take decades. But if it begins in your twenties, you have more decades for it to play out. Someone crowned at 65 may never need a second crown on that tooth. Someone crowned at 25 very likely will.

What to try first if your teeth are healthy

Whitening

If colour is the main issue, whitening changes the shade of your own teeth without drilling. It also sets the shade for any future work, because crowns and veneers do not whiten.

Composite bonding

Bonding adds tooth-coloured resin to chips, gaps, worn edges and small or misshapen teeth. It usually needs little or no drilling. It is not as long-lasting as ceramic: a systematic review of front-tooth composite work reported annual failure rates from 0% to 4.1%, with fracture the most common problem (Demarco and colleagues, 2015). The point is that a failed bonding can usually be repaired, and your tooth is still mostly there.

Veneers

Veneers cover the front face of the tooth. They take more tooth than bonding but much less than a crown. See crowns vs veneers for when each makes sense.

Orthodontics

If your teeth are crooked, crowding is often the real problem. Crowning crooked teeth to make them look straight can mean heavy drilling on the teeth that stick out most. Straightening first sometimes removes the need for crowns entirely, or means far less preparation.

When a crown is right at any age

Age is not a reason to refuse a crown that a tooth needs. A molar that has split, a tooth that is mostly filling, or a back tooth that has had root canal treatment and lost a lot of structure may be best protected by a crown, whether you are 22 or 72. Our article do you really need a crown? sets out which situations those are, and onlays and partial crowns covers the middle ground.

The aim is to crown the teeth that need it and protect the ones that do not.

If you do have crowns young, look after them

Since decay and gum disease were the main reasons crowns failed in the long-term studies above, the most useful things you can do are boring ones: clean carefully along the gum line, use floss or interdental brushes, keep regular check-ups and X-rays, and wear a night guard if you grind. Our page on aftercare and longevity covers this in more detail, and the conditions of our 5-year written guarantee include regular check-ups for the same reason.

Thinking about the whole mouth, not one look

A useful way to plan at this age is to sort your teeth into three groups. The first group is teeth that are already damaged: large fillings, root canal treatment, fractures. These may well need crowns or onlays now or soon, and treating them is not the same as cosmetic crowning. The second group is teeth that are healthy but you dislike their colour, shape or position. These are where whitening, bonding, veneers or straightening are worth trying first. The third group is teeth that are healthy and look fine. These rarely need touching, even if a "full set" sounds neater.

A plan built this way often ends up mixed: perhaps crowns on two or three heavily filled teeth, bonding on a few front teeth with chips, and nothing at all on the rest. It may not give the uniform, very white look some people expect from social media. It does keep the most natural tooth for the decades ahead, and it leaves the bigger options open if you still want them later.

If you decide on ceramic for the front teeth, the choice of material matters too. Our pages on E-max and zirconia explain how they differ.

Questions to ask before crowning in your 20s or 30s

• Which of my teeth actually need crowns for health reasons, and which are cosmetic?
• For the cosmetic ones, what are the lighter options, and what would they look like?
• How much tooth will be removed on each tooth?
• Are any of the nerves at risk because the teeth are being moved a long way in shape or position?
• What will this tooth likely need in 15 years?

At Precious Dental we prefer to protect a healthy tooth rather than crown it. If a lighter option suits some of your teeth, your plan will say so. Send your photos and any X-rays through our contact page and we will reply with a free written plan, tooth by tooth.

Common questions

How many times will a crown need replacing in my lifetime?

Nobody can give an exact number. Studies following crowns for 18 to 25 years show most still in place, but some fail in that time. If you are crowned at 25, it is realistic to plan for at least one or two replacements, and each replacement can take a little more tooth.

Is it ever right to have crowns in your twenties?

Yes, when the tooth needs it: a badly broken tooth, a root-filled back tooth that has lost a lot of structure, or a failed large filling. The concern is crowns on healthy teeth for appearance alone.

Is bonding a waste of money if it needs redoing?

Not necessarily. Bonding usually needs little or no drilling and can be repaired. Even if you redo it a few times, your natural tooth stays largely intact, and crowns remain possible later.

Can crowned teeth be turned back into natural teeth?

No. Once a tooth has been shaped for a crown, it will always need a crown or similar covering. That is the main reason to be sure before starting.

Will you crown healthy teeth if I ask?

We prefer to protect a healthy tooth rather than crown it, and we will tell you if we think a gentler option suits you better. Your written plan sets out what we recommend for each tooth.
