Veneer Fell Off or Broke? What to Do First, and What Happens Next

Is a veneer falling off an emergency?

Usually not a medical emergency, but it should be seen soon. A prepared tooth without its veneer is more prone to sensitivity, can chip at its edges and, if left for weeks, can shift slightly so the veneer no longer fits. Book as soon as practical rather than waiting until it is convenient.

It is more urgent if:

• part of the tooth came away with the veneer, or the tooth is cracked;
• there is pain, especially throbbing or pain on biting, or the gum is swelling;
• the tooth was knocked, for example in a fall or during sport;
• a sharp edge is cutting your tongue or lip.

Our emergency dentist page explains how urgent problems are handled during clinic hours. If you have facial swelling with difficulty breathing or swallowing, or a head or face injury, go to a hospital emergency department immediately. If you think you inhaled the veneer rather than swallowed it, and you are coughing, wheezing or short of breath, get medical help straight away.

Veneer came off, chipped or cracked: what to do

Can a veneer that fell off be bonded back on?

Often, yes, if three things are true: the veneer is intact with no cracks, it still fits the tooth precisely, and the tooth itself is healthy. Rebonding is not simply re-gluing. Old cement is removed from the tooth and from the inside of the veneer, the tooth is checked for decay, the inner surface of the ceramic is re-treated so fresh cement can grip it, and the veneer is bonded and the bite checked again, much like the original fitting.

That is why home glue causes problems. It fills the space unevenly, so the veneer sits high and takes extra bite force; it can trap bacteria against the tooth; and removing it can crack the veneer, ending any chance of reusing it.

If the veneer cannot be reused, a new one is made. When only one or two teeth are involved, it has to match the others closely, which is a demanding shade job; our page on the single tooth veneer explains how that matching is done.

Why do veneers come off or break?

Most failures have an identifiable cause:

• Grinding and clenching. Repeated force on the edges at night is the most common reason veneers chip; our guide to veneers and teeth grinding explains how it is managed.
• Biting hard objects. Nails, pens, ice, bottle tops and packaging put sideways forces on edges that ceramic handles poorly.
• A bite that hits the veneer first. If one veneer takes more force than its neighbours, it tends to fail first.
• The bonding surface. Veneers hold most reliably on enamel. Bonding largely to dentine or old fillings, or moisture during bonding, weakens the hold.
• Decay or gum recession at the edge. Ceramic does not decay, but the tooth at its margin can, undermining the bond.
• A knock or fall, which can break both the veneer and the tooth beneath it.
• Age. Bonds and margins do not last forever; see how long veneers last.

Rebond, repair or replace: how the dentist decides

The decision depends on the veneer, the tooth and why it failed. A sound veneer on a healthy tooth is usually rebonded. A small chip may only need polishing or a composite repair. A cracked or lost veneer, decay under the margin, or a tooth that has changed since the veneer was made usually means a new veneer. If too little sound tooth remains, or the tooth has had root canal treatment, a dental crown may protect it better.

Replacement ceramic is made by Creative Art Dental Lab in the same building as our Dubai clinic, so the ceramist can compare the new veneer with your remaining teeth in person. Removing old cement and checking the tooth under magnification is careful restorative work, which is why Dr. Marina Antoniuk, whose focus is restorative and microscopic dentistry, is often involved.

If your veneers were made at another clinic or abroad

A veneer from another clinic, in Dubai or overseas, is assessed and rebonded or replaced in the same way. Bring whatever records you have: the material, shade, date and clinic details, and any X-rays. Matching a replacement is harder when the original material and shade are unknown, and the dentist will tell you if replacing a neighbouring veneer would give a more even result. Aftercare at a distance is one of the trade-offs discussed in our guide to veneers in Dubai vs Turkey.

How to lower the chance of it happening again

Most of what makes veneers fail can be managed:

• Wear a night guard every night if you grind or clench.
• Do not use your teeth as tools, and cut hard food rather than biting it with veneered teeth.
• Wear a sports mouthguard for contact sports.
• Keep up daily cleaning at the gum line and regular hygiene visits, so problems at the edges are caught early.
• Ask for a bite check if a veneer ever feels as if it hits first.
