What a veneer is
A shell of porcelain, roughly the thickness of a contact lens, bonded to the front of a tooth. It covers the colour underneath and changes the shape of the edge, which together is most of what people mean when they say they want a better smile.
It covers the front and the biting edge. It does not cover the back, which is why a veneer needs a fundamentally sound tooth underneath it. A tooth that is heavily filled or broken needs a crown instead, and that difference decides a great deal.
How the treatment runs
- Planning. Photographs, a scan, and a conversation about shape and colour that is longer than you expect. This is where the result is decided, not at the fitting.
- A trial smile, where the case earns it. The proposed shape is built in temporary material in your mouth so you can see it before anything is removed. We use this whenever the change is significant.
- Preparation. A third to a half of a millimetre of enamel off the front surface, under local anaesthetic. Temporaries go on the same day.
- The laboratory. Ten days or so while the porcelain is made and shaded. Rushing this stage is where cases go wrong.
- Fitting. The temporaries come off, the fit and the colour are checked with you before anything is bonded, and then they are bonded permanently.
How long they last
Ten to fifteen years is the realistic range, and plenty last longer. They rarely fail suddenly. What happens is slower: the gum recedes a little over the years, the join at the gum line starts to show, and at some point you decide it is time.
Budget for replacement rather than treating the first set as the end of it.
What they cannot fix
Veneers change how a tooth looks from the front. They do not move teeth, they do not treat gums, and they do not make anything stronger.
Badly crooked teeth covered in porcelain still sit where they sat. The porcelain has to be built thicker on one side to fake the alignment, which means more enamel removed and a bulkier result. If the teeth are in the wrong place, move them first. It costs less and it takes nothing away.
The alternative worth trying first
If your teeth are a good shape and the only complaint is colour, veneers are an expensive answer to a cheap problem. Whitening removes nothing, costs a fraction, and can be repeated. Try it, live with it for a month, then decide.
We would rather you whitened and left than had porcelain you did not need. If you want the comparison with the heavier option, it is on veneers compared with crowns.
