Cosmetic Dental Treatments Explained
The most useful way for UK readers to compare cosmetic dental treatments is by how much of your own tooth they take away, and whether that can be undone. Price and appearance come second, because enamel that has been removed does not grow back.
These guides are written for UK readers; we are not a clinic and do not rank clinics. For treatment in Turkey, see the Turkey teeth guide.
Each guide links to its sources, and we publish prices only in our cost section, where the costs are explained.
The main options side by side
The table is the short version; each row hides variation between patients, so read the linked guide.
| Treatment | Is tooth removed? | Can it be undone? | Typical lifespan | Typical sessions | Guide |
|---|---|---|---|---|---|
| Composite bonding | Little or no tooth preparation; resin is added to the tooth | Largely — little or no tooth removed, though the enamel is etched | No single dependable figure; studies vary widely, see guide | Built directly on the tooth, with no laboratory stage; see guide | Composite bonding |
| Teeth whitening | No shaping of the tooth | Colour change fades; no tooth removed | May last around 3 years, according to the National Health Service (NHS) | Home kit usually 2 to 6 weeks; in-surgery laser 1 to 2 hours, according to the NHS | Whitening |
| Veneers | Some enamel, depending on the design | No — tooth preparation is permanent | Around 8 to 10 years for a crown or veneer with good care, according to an NHS hospital leaflet; studies vary | Preparation, then fitting; ask for the schedule in writing | Veneers |
| Crowns | The most: the tooth is reshaped all the way round | No — tooth preparation is permanent | Around 8 to 10 years with good care, according to an NHS hospital leaflet | Preparation with a temporary crown, then the permanent one; see guide | Crowns |
| Dental implants | Replace a missing tooth; the jaw bone is operated on | No — surgery | Studies vary; see guide | Staged over months: surgery, healing, then the final tooth; see guide | Implants |
Treatment comparison
What changes in the natural tooth?
Treatments that reshape the tooth
Veneers and crowns both involve preparing a natural tooth: a veneer covers the front, while a crown goes all the way round. The veneers guide explains “no-prep”, crowns covers when full coverage is justified, and crowns versus veneers shows how to tell them apart on a quote.
Treatments that add to the tooth or leave it alone
Composite bonding builds up a tooth with resin, usually with little or no cutting, so it is the least-invasive starting point, though it can stain and wear. Teeth whitening changes colour only, and in the UK it is regulated, so it matters who provides it.
Treatments that replace teeth
A dental implant replaces a missing tooth root with a post set into the jaw: it is surgery, it needs months to heal, and some people are poor candidates. All-on-4 applies the idea to a whole arch.
Materials and planning
Our guide to dental materials explains how what a restoration is made of affects how it looks and ages. A smile makeover combines several treatments, so it needs a written plan that includes the option of doing nothing.
Veneers

Start with the least invasive option that would solve the problem, and move to a more invasive one only for a clear reason. Sometimes the answer is to monitor a tooth and do nothing.
Ask four questions of any plan. What problem is it solving? What are the alternatives, including no treatment? How much tooth will be removed, and can that be undone? Who looks after the result in five years? Get the answers in writing.
Only a dentist who has examined you can say which treatment suits your teeth; our editorial standards explain how we choose sources.
