Veneers next to old crowns, fillings and implants

A 25-year-old with untouched teeth is a straightforward veneer case. A 60-year-old with two crowns, an implant, a bridge and several white fillings is not harder in principle, but the plan has more parts. The key fact to hold on to is this: the NHS notes that whitening only lightens the colour of natural teeth. Everything else in your mouth stays the colour it is now. That one fact decides most of the planning.

Make a list of what is already there

Before any plan, write down, or ask your UK dentist to list, every restoration in the part of your mouth that shows when you smile widely:

• Crowns: which teeth, roughly how old, and whether they are porcelain, metal-ceramic or zirconia.
• Bridges: which teeth they replace and which teeth hold them.
• Implant teeth: where, and if you have an implant card, which system.
• White fillings on front teeth, especially any that look stained at the edges.
• Root-filled teeth, which may be darker than their neighbours.
• A partial denture replacing any front teeth.

Send this with your photos. It turns a vague quote into a real plan. See photos to send for a quote.

Match to what, exactly?

There are two basic strategies:

The second route gives a lighter result but costs more, because every visible crown or implant tooth that is darker than the new shade will stand out unless it is replaced. The clinic should tell you which ones would clash, and you can decide which to replace now and which to leave.

Old crowns: keep or replace?

Reasons a crown may need replacing as part of a veneer plan:

• Its colour will clash with the new shade.
• The edge at the gum has become dark or visible as the gum has receded.
• It is chipped, loose or has decay underneath.
• Its shape no longer suits the new smile, for example it is shorter than the new veneers beside it.

Reasons to keep it: it is recent, sound and a good colour match; it sits far enough back not to show; or replacing it would mean disturbing a tooth that is fine. Replacing a crown is not a small thing: the old crown is cut off, the tooth checked and a new crown made. Ask for each replacement to be listed separately in the plan, with its price. The Oral Health Foundation's crown guide explains what is involved.

Old white fillings

Front teeth often have white fillings on the sides or edges, placed years ago. They tend to stain at the edges and can leak. If a tooth is getting a veneer, the dentist will usually remove any old filling in the area being covered and either replace it or let the veneer cover it with fresh bonding underneath. Veneers bond best to clean enamel. The NHS describes how decay can spread if left untreated, so any decay found under an old filling must be dealt with first.

If an old filling is very large, a veneer may not have enough tooth to hold onto, and a crown may be the better choice for that tooth. The reason should be written next to it. See veneers or crowns?

Root-filled teeth

A tooth that has had root canal treatment can darken over the years. It is also more brittle. For such a tooth next to new veneers, options include whitening it from inside, a veneer with a masking layer, or a crown if it is weak. Our article on veneers for dark or stained teeth explains the choices.

Implant teeth

An implant tooth is a crown on an implant. Its colour is fixed. If it sits among the teeth getting veneers, the new veneers can be matched to it, or the implant crown can be remade in the new shade. Remaking the crown on top of an existing implant is usually possible without touching the implant itself, but the clinic needs to know the implant system. Bring your implant card or passport if you have one.

Bridges

A bridge replaces a missing tooth using crowns on the teeth either side. Because it is one piece, changing the shade of one part means remaking the whole bridge. If a bridge sits in your smile and you want a lighter shade, factor in the cost of a new bridge, or choose a veneer shade that matches it.

Partial dentures

If you wear a partial denture that replaces a front tooth, its tooth will look darker next to new veneers. A new denture tooth, or a new partial denture, can be made in the new shade. Some people use the opportunity to replace a denture with an implant or bridge; that is a bigger decision with its own timeline.

Shade matching in practice

Matching ceramic to existing ceramic is easier than matching ceramic to natural teeth, but it still needs care. Guidance on shade matching recommends checking in natural daylight and then under other lighting, because two materials can match under one light and not another (Alayed et al., 2021). At the try-in, look at the new veneers beside your crowns and implant teeth by a window. See the try-in appointment.

Planning the order

1. List existing workEvery crown, filling, implant and bridge in the smile.
2. Decide the target shadeKeep the current colour, or go lighter.
3. Whiten natural teethIf going lighter, before the trip.
4. Decide what to replaceCrowns, bridges or implant crowns that will clash or are failing.
5. Prepare and replace togetherVeneers and replacement crowns are usually made at the same time so they match.
6. Check at try-inAll the new work side by side, in daylight.

A typical example

Consider a common situation, not a real patient: someone in their sixties has an old porcelain crown on one upper front tooth, white fillings on two others, and wants a lighter smile. A sensible plan might be to whiten the natural teeth at home first, replace the old crown in the new shade at the same time as placing veneers on the filled teeth, and leave sound back crowns that do not show. The plan would list each item separately: whitening, one new crown, the veneers, and a note that the back crowns stay.

Questions to ask

• Which of my existing crowns, fillings and implant teeth will show next to the veneers?
• Which would clash with the new shade, and what would replacing them cost?
• Can I keep any of them by choosing a slightly different shade?
• What happens to the old fillings in teeth getting veneers?
• Will the new veneers and any new crowns be made together?

Common questions

Can my old crowns be whitened to match new veneers?

No. Whitening only works on natural teeth. Crowns, veneers, fillings and implant teeth keep their colour.

Do I have to replace all my crowns?

Only those that would clash with the new shade, or that are failing. Crowns at the back that do not show may be left as they are.

What happens to old fillings under veneers?

Small sound fillings can sometimes stay. Old, stained or leaking fillings are usually replaced during preparation so the veneer bonds to a clean surface.

Can a veneer go next to an implant tooth?

Yes. The veneer is matched to the implant crown, or the implant crown is remade to match the new shade, depending on which is easier and what you want.

Will replacing old crowns add to the cost?

Yes. Each replaced crown is an extra item in the plan. Ask for it to be listed separately so you can see what it adds.
