Planning & advice · Under-18s
Can under-18s have cosmetic dental treatment?
The honest answer: yes, but only for the right reasons. For under-18s we treat for health, function or a genuine problem — a tooth chipped in an accident, a discoloured or peg-shaped tooth, worn edges — always using the most conservative, reversible option. Purely cosmetic “Hollywood” makeovers aren’t appropriate for a still-growing smile, and we’ll say so.

The right reasons
When is cosmetic treatment right for a younger patient?
The line we draw is simple: for anyone under 18, treatment is led by health, function and genuine need — not by the wish for a dramatically different smile. Teeth, gums and jaws are still developing through the teenage years, so the aim is to help, protect or restore a tooth with the least invasive option, and to avoid anything irreversible until growth is complete. Within those principles there are plenty of situations where careful treatment is appropriate — and each has a gentle, age-appropriate answer:
A chip or break from trauma
A front tooth chipped playing sport or in a fall can usually be rebuilt the same day with composite bonding — added onto the tooth, and easily adjusted or repaired as the smile keeps growing.
A tooth discoloured after injury
A tooth that darkens after a knock can often be lightened from the inside with internal bleaching, or its shade gently evened with whitening — once we have checked the nerve underneath is healthy.
Small or peg-shaped teeth
Teeth that formed unusually — such as a small, pointed “peg” lateral incisor — can be built into a natural shape with composite bonding, with nothing permanent removed.
White marks on the enamel
Chalky white spots from fluorosis, illness or an early knock can often be softened without any drilling — with ICON resin infiltration or microabrasion rather than a filling.
Worn or eroded edges
Where grinding or acid erosion is wearing young teeth down, rebuilding the edges with bonding protects them as well as improving how they look.
Bite & alignment problems
Crowding, gaps or a bite that does not meet properly are best corrected with orthodontics — usually braces for a developing smile, or Invisalign and removable appliances in motivated, suitable cases.
A missing or knocked-out tooth
Where a tooth is lost, a minimally invasive resin-retained (Maryland) bridge can fill the gap with almost no drilling — holding things naturally until an implant becomes an option in adulthood.
Health and function come first
Every plan for a younger patient starts from the question a good dentist always asks: what does this tooth actually need? The role of a GDC-registered cosmetic dentist is to recommend the least invasive treatment that genuinely helps — and, just as often, to advise watching and waiting rather than intervening. Parents are part of every conversation, and nothing irreversible is ever rushed on a smile that’s still growing.
What we hold back on — and why
Being honest is part of ethical care, and sometimes that means saying no, or not yet. Permanently reshaping or replacing teeth is hard to justify while a smile is still settling into its adult position, so a few treatments are deliberately kept off the table for under-18s:
- Porcelain veneers — a no. Veneers permanently reshape healthy enamel, which cannot be justified on developing teeth. On a cosmetic basis they are not appropriate under 18; in the rare case one is genuinely needed, it waits until growth is complete.
- Crowns — for health reasons only, as a last resort. A crown is considered solely to save a badly broken or root-treated tooth, never for appearance. Wherever a tooth can be restored more conservatively — usually with bonding — we do that instead.
- Dental implants — deferred, usually to 21–25+. An implant is fixed and does not move, but a young person’s jaw is still growing and their teeth are still erupting. Placed too early it can end up looking sunken and out of line, so we wait until the jaw has finished maturing.
- Cosmetic whitening — not permitted. In the UK, whitening products strong enough to work cannot legally be supplied to under-18s for cosmetic reasons — only a dentist may provide them, and only to treat or prevent disease. More in our guide to whitening law and safety.
For most younger patients the kindest plan is to treat any real problem conservatively now — with bonding, orthodontics or a minimally invasive bridge — keep an eye on things, and revisit anything elective in adulthood if they still want it.
The gentlest route
Why we choose the most conservative option
When something does need doing, the choice of treatment matters as much as the decision to treat. For a younger patient we almost always favour composite bonding over porcelain veneers — because it protects the natural tooth and keeps every future option open.
| Composite bonding | Porcelain veneers | |
|---|---|---|
| Tooth alteration | None, or extremely minimal | Permanently reshapes healthy enamel |
| Reversible | Usually yes | No — it’s permanent |
| Suits a developing smile | Yes — easily adjusted as teeth mature | Rarely suitable before adulthood |
| Typical role under 18 | Repair a chip, rebuild a small tooth, mask a mark | Very rarely — usually deferred |
| Our preference for teens | First choice | Almost always postponed |
It’s the same reasoning we apply to every patient: find the least invasive treatment that genuinely achieves the goal. If you’d like the detail, our guides on who bonding suits and whether bonding damages teeth explain why it’s so gentle.
Consent, and how an assessment works
Nothing begins with a treatment — it begins with a conversation. For anyone under 16, a parent or guardian must give consent, and we involve parents at every age under 18. The young person is always part of the discussion too; it’s their smile, and understanding what’s proposed helps them look after it.
At the consultation, Dr. Albert examines the teeth and gums, checks that anything being treated is healthy underneath, and explains the options plainly — including the option to do nothing for now. Genuinely necessary dental care for under-18s is generally available on the NHS, while bespoke cosmetic work is private. Sometimes the best advice really is to wait, monitor a tooth, and let the smile finish developing.
Where treatment is right, we always start with the least invasive plan, individually designed for that one young patient rather than applied from a template. If you’re not sure where to begin, tell us what’s bothering you and we’ll take it from there.
Common questions
Cosmetic treatment for under-18s: your questions answered
Can a 16-year-old have composite bonding?
Yes, where there is a genuine clinical reason — such as repairing a tooth chipped in an accident, rebuilding a small or peg-shaped tooth, or masking a mark. Composite bonding suits younger patients because it is additive and usually reversible, adding little or no risk to a still-developing tooth. A parent or guardian is always involved.
Can under-18s have porcelain veneers?
Very rarely, and almost never for purely cosmetic reasons. Veneers involve permanently reshaping healthy enamel, which is hard to justify on teeth and gums that are still maturing. For a younger patient we would nearly always choose composite bonding first, or simply wait until growth is complete before considering anything irreversible.
Can under-18s have dental implants?
Almost never, and we usually advise waiting until around 21 to 25 or older. An implant is fixed permanently in the jaw and does not move, but a young person’s jaw is still growing and their natural teeth are still erupting — so an implant placed too early can end up sitting low and out of line with the teeth beside it. Where a tooth is missing in the meantime, a minimally invasive resin-retained (Maryland) bridge can hold the space and the look until implants are appropriate.
Can teenagers have braces or Invisalign?
Yes — orthodontics is often the ideal treatment for a developing smile, because it guides teeth into a better position rather than permanently altering them. Fixed braces are the usual choice and suit almost any case; Invisalign or other removable appliances can work well for motivated teenagers with suitable, less complex cases. Correcting the bite and alignment early is health-led, not just cosmetic, and often removes any later wish for veneers.
How do you replace a missing tooth in someone under 18?
Conservatively, and without an implant. Because the jaw is still growing, we avoid implants until adulthood and instead restore a gap with a minimally invasive resin-retained (Maryland) bridge, which bonds a replacement tooth to the neighbour with almost no drilling. It looks natural, protects the space, and keeps every option open for when an implant becomes suitable later.
Is composite bonding safe for a child’s chipped tooth?
In most cases, yes. Bonding a chipped front tooth usually needs little or no drilling and no anaesthetic, and the tooth-coloured resin is added onto the existing tooth rather than cutting it down. If a chip is painful, sensitive or bleeding, though, see a dentist promptly, as the nerve may be involved.
Do you need parental consent to treat an under-18?
Yes. For anyone under 16, a parent or guardian must give consent, and we involve parents throughout the process at any age under 18. The consultation is an open, unpressured conversation with the young person and their family together, so everyone understands what is proposed, what it involves, and why.
Can you fix a tooth that discoloured after an injury?
Often, yes. A tooth that darkens after a knock can frequently be lightened from the inside with internal bleaching, or its shade gently masked with conservative composite bonding, depending on the cause. We assess the tooth first — including whether the nerve is still healthy — because treating the underlying problem always comes before the appearance.
Is cosmetic dentistry appropriate for teenagers?
It depends entirely on the reason. Where there is a real, visible problem affecting a young person — a chipped, worn, discoloured or unusually shaped tooth — conservative treatment can be very worthwhile. Purely elective “Hollywood smile” work on a growing child is not something we offer, and professional whitening is not available to under-18s for cosmetic reasons.
