Composite bonding or veneers: a light touch or a full redesign?
Both treatments change the way front teeth look, and both are done in our cosmetic clinics every week. Bonding adds resin exactly where a tooth needs it, leaving the rest alone. A veneer covers the whole front face of the tooth with a new surface, in composite or porcelain, so colour, shape and alignment can all be reset at once. The right choice depends on how much you want to change and how long you want it to last.
Decision guide
Which is right for you?
Choose Composite bonding if…
- You are happy with the overall colour of your teeth and want to fix one or two details.
- You would prefer not to have any enamel removed.
- You want the work completed in a single visit at a lower cost.
- You are not sure yet and want an approach you can build on or reverse.
Choose Veneers if…
- Several front teeth are stained, misshapen or slightly crooked and you want them to match.
- Whitening has not lifted the colour enough, or the discolouration is inside the tooth.
- You want the most stain-resistant, longest-lasting surface and are comfortable with minimal preparation.
- You are planning a full smile design rather than a repair.

What the treatment involves
Composite bonding
The dentist selects resin shades to blend with the surrounding tooth, prepares the enamel with a mild etch and bonding agent, and then builds up composite only where it is needed: a missing corner, a worn edge, the side of a gap. Each layer is cured with light before the next is added. Shaping is done by eye and by hand, and the final polish brings the surface up to the gloss of natural enamel. Most single-tooth cases take under an hour and need no anaesthetic.
Veneers
Composite veneers follow a similar technique to bonding but cover the whole front surface, so the dentist reshapes the entire face of the tooth in resin during one longer visit. Porcelain veneers begin with planning and often a trial smile in temporary material. A very thin layer of enamel is removed to make room, impressions or scans are sent to a ceramist, and provisional veneers are worn for a week or two. At the second visit the porcelain shells are tried in, adjusted for shade and fit, and bonded permanently.
Fees
Cost and longevity at Wimpole Street
Composite bonding at Wimpole Street will start from £395 per tooth. Composite veneers start from £595 per tooth and porcelain veneers from £1,095 per tooth. A typical cosmetic case involves between four and ten teeth, so the choice of material has a large effect on the overall figure.
Longevity roughly tracks price. Bonding and composite veneers usually last five to ten years with periodic polishing; porcelain veneers commonly last ten to fifteen years and keep their colour better. When comparing options, it is worth thinking in cost per year as well as the upfront fee.
All prices are indicative and are confirmed in a written treatment plan at your consultation. Fees are the same at every Medical & Dental clinic.
Weighing it up
Strengths and trade-offs
Composite bonding
Strengths
- Keeps every millimetre of natural enamel
- Single appointment with an immediate result
- Lowest fee per tooth of the cosmetic options
- Simple to repair or extend later
- Fully reversible if you change your mind
Trade-offs
- Cannot mask deep or intrinsic discolouration
- Limited scope for changing tooth shape or alignment
- Stains and loses gloss over time
- Vulnerable to chipping under heavy bite forces
Veneers
Strengths
- Transforms colour, shape and symmetry across a whole smile
- Porcelain is highly stain-resistant and long-lasting
- Can disguise mild crowding or spacing without braces
- Laboratory craftsmanship gives exceptional lifelike detail
Trade-offs
- Porcelain requires irreversible enamel reduction
- Higher fee per tooth, especially for porcelain
- Two visits and a temporary phase for porcelain
- A damaged porcelain veneer is replaced rather than repaired
FAQ
Common questions
In technique, broadly yes: both use resin applied directly. The difference is coverage. A composite veneer resurfaces the entire front of the tooth, which allows a change of colour and shape, whereas bonding is placed only where a correction is needed.
Small gaps of a millimetre or two are a classic use of bonding: resin is added to the sides of both teeth to meet in the middle. Wider gaps may look better with veneers or aligners, because adding too much width to two teeth can make them look oversized.
Both can be indistinguishable from natural teeth when done by an experienced dentist. Porcelain has an advantage in translucency and how it handles light, which matters most when many teeth are being changed together.
Usually around half a millimetre from the front surface, sometimes less with modern minimal-prep techniques. It is permanent, which is why we discuss it carefully before starting.
Yes. Because bonding leaves the enamel untouched, veneers remain fully possible afterwards. Some patients deliberately start with bonding to test a new shape before committing to porcelain.
Yes. Both are core cosmetic services at Medical & Dental and will be offered in Marylebone from 1 October 2026. Consultations and treatment are available now at South Kensington and St Paul’s with the same dentists.
