Usually worth it, provided the occlusion does not eat up the room for ceramic
- Veneers on lower teeth hold the worse the less enamel is left: a translucent, thinned incisal edge signals trouble, and the thinnest enamel lies right at the gum.
- The edges of the lower incisors collect the contact with the upper teeth when the teeth come together. In the upper arch that contact usually falls on the palatal surface, that is outside the veneer.
- With heavy grinding, ceramic in the lower arch can be a worse choice than bonding (restoration with composite) or a crown.
- Preparation cannot be undone. Enamel that has been ground away does not grow back, and from that moment the tooth needs a restoration for good.
- The durability percentages a patient hears come above all from the upper arch. The prognosis for the lower incisors is derived, not measured.
Why is there less room for ceramic on a lower incisor?
Usually because there is simply less enamel there. On the labial surface of the lower incisors it measures from 0.34 to 0.79 mm. On the upper central incisors from 0.46 to 0.97 mm. That is how a micro-computed tomography measurement on extracted teeth came out. Those are laboratory conditions, not a measurement taken in a patient.
A standard veneer preparation removes from 0.3 to 0.5 mm from the labial surface, more at the incisal edge, and at the gum it is sometimes as much as all the enamel there is. On a lower incisor the margin for error is therefore close to zero and exposure of dentine happens more easily than in the upper arch.
There is a second obstacle, on which the plan founders just as often: the ceramic itself also has to have a thickness of its own, because too thin a layer fractures during bonding. The room for it has to be either ground out or found between the arches. Grinding on a lower incisor risks entering dentine. In somebody with worn incisal edges there is usually no space between the arches. It then has to be created before the restoration. None of the studies cited gives a limit below which ceramic is already too thin.
With enamel the luting cement bonds strongly and durably. With dentine that same bond weakens faster. The risk probably rises even with limited exposure of dentine. Veneers bonded to enamel alone survived in about 97 out of 100 cases; where dentine took up more than 30 percent of the prepared surface it was just under 94 out of 100, but counted on only 76 teeth. Both figures come from one retrospective series of veneers followed from one to fifteen years. Only the second comparison reached statistical significance, but every exposure of dentine was associated with a higher risk of failure.
Lower incisors wear throughout life. A fifteen-year research programme devoted to worn teeth describes that loss as a process that is largely physiological and age-related, not pathological. The rate, however, varies greatly: in measurements it ranged from 10 to 500 micrometres per year, that is from a change imperceptible over a decade to a visibly worn edge. Somebody who comes for veneers because of wear therefore usually has less enamel than the measurements show.
How does the lower arch differ from the upper, and what is not known about it?
| What we compare | Upper incisors | Lower incisors |
|---|---|---|
| Enamel on the labial surface | Thicker, with a reserve at the incisal edge | Thinner, thinnest at the neck |
| Role in occlusion | Guide the movement of the mandible with the palatal surface | Take the contact on the edge, that is on the margin of the restoration |
| Risk of debonding | Lower, because the preparation usually stays within enamel | Probably higher, because that same layer more often reaches dentine |
| Typical complication | Fracture and chipping of the ceramic | Expected chipping of the edge and wear at the point of contact |
| Predictability in a patient | Depends mainly on the thickness of the enamel | Depends on the enamel and on where the contact falls in occlusion |
| How much is known about it | Most of the data from studies concern this arch | Partial data, because few lower veneers are done |
In the series of 672 veneers cited, only 15 percent were placed on lower teeth. That does not mean that lower veneers are unreliable. It means that their prognosis is derived from data gathered elsewhere, and that this has to be said to the patient plainly, instead of carrying percentages over from one arch to the other. The same applies to the routine of adding lower veneers to an upper plan for symmetry. The studies cited do not assess that routine separately.
Technical complications - that is fractures, chips, debonding and gaps at the margin - are far more frequent than the loss of a whole restoration. With older types of ceramic they affected from 30 to 41 percent of veneers after an average of ten years, with a wide spread between studies. Survival and freedom from complications are two different figures and the patient usually hears only the first of them.
What to ask before deciding on the lower arch?
Before a date for the procedure is set, ask plainly:
- How much enamel is left on my lower incisors, and can it be seen on the radiographs or in the scan?
- Will the preparation stay within enamel, or will it enter dentine somewhere?
- Will the preparation stay within enamel, or will it enter dentine somewhere?
- Jaki jest plan zapasowy, gdyby w trakcie opracowania okazało się, że szkliwa jest mniej, niż widać?
The decision - whether we stay with ceramic or come down to composite - is sometimes made only in the chair.
The first and the third question make sense only before the tooth is prepared; the thickness of the enamel is assessed approximately on a radiograph, and a diagnostic wax-up shows how much will have to be taken. That is an estimate, not a measurement: accurate measurements of enamel thickness come from studies on extracted teeth. The contact points can be seen on articulating paper in a minute.
Occlusion and bruxism - the main limitation of the lower arch
The conditions here are stricter than in the upper arch, and occlusion and bruxism are two different obstacles; on occlusion itself what speaks here is clinical knowledge, not the studies cited. Occlusion decides where the contact with the opposing tooth falls, and it can rule out a veneer in somebody who does not grind at all; bruxism adds force and repetition to that, loading exactly the edge on which a lower veneer ends.
Grinding is among the factors associated with a higher risk of failure of a restoration. Alongside grinding stand ineffective hygiene and the age of the work itself. That is how an observation reaching eight years came out, on restorations of the upper anterior teeth combining ceramic with composite.
In the series of veneers followed for up to fifteen years, patients who ground their teeth were not excluded from treatment, but they were required to wear a hard splint at night. Minor chips of the ceramic occurred almost exclusively in them and in people who bite their nails, and most of those events appeared only after ten years of use.
A splint shields the teeth and the restorations from the effects of nocturnal grinding. Clenching the teeth during the day - often unconscious - stays beyond its reach. A diagnosis of grinding therefore does not close the road to veneers in the lower arch, but it does change the conversation about their durability. We write more broadly about overloading itself in the article on bruxism and prosthetic work.
In everyday clinical practice at Modern Dental & Orthodontics (Klinika MDO) we come across requests for veneers on the lower arch because the edges of the incisors have become uneven from wear. It is worth asking then about the cause. Restoring the edges without addressing it is repairing a symptom. A new edge made of ceramic will meet the same load that destroyed the patient’s own edge. Where grinding is suspected, the order is sometimes the reverse of the expected one: first an assessment of the muscles of mastication and of wear on the opposing teeth, then a splint and observation, and only at the end a decision about the extent of the restoration.
When are veneers on lower teeth better replaced by bonding or a crown?
Usually when the ceramic has run out of foundation or the load is too great. Veneers on lower teeth stop being a sensible choice in three situations: when the preparation would have to go deep into dentine, when the margin of the restoration falls exactly on the point of contact with the opposing tooth, and when there is no room for a layer of ceramic between the arches.
Bonding, that is restoration with composite, requires less grinding, and not infrequently does without it altogether. In the research programme devoted to worn teeth, composite on the anterior teeth failed less often than once per forty restorations per year, with follow-up reaching five and a half years. The material wears faster than ceramic, but damaged composite can be repaired in the mouth. Where the prognosis is uncertain, that is an advantage, not a lower standard.
With slight wear of the lower incisors, bonding costs less healthy tooth and can be reversed. The same cannot be said of a veneer: there is no way to restore enamel that has been ground away.
A crown comes into play when a veneer would have nothing to hold on to: with an incisal edge worn down to dentine, with enamel missing on the lingual side as well, or with a tooth already extensively filled. The common denominator is one: the preparation would go beyond the enamel anyway, so saving tissue stops being an argument. A crown is not a better choice - it is a choice for a different starting situation, and the question of veneers or crowns is answered by a separate article.
A third route, spoken of less often, is to postpone the restoration; observation with measurement on intraoral scans shows whether the process has stopped or is still running.
We describe the choice of veneer material in the article on porcelain or composite veneers.
What veneers in the lower arch will not improve: crowding, exposed necks and wear
Ceramic masks shape and colour. It does not change the position of the teeth in bone. Crowded lower incisors still stand where they stood after veneers are placed, and a layer of material on the labial surface may make the crowding stand out even more. Teeth are aligned by orthodontic treatment. With marked crowding the order is sometimes this: align them first, then possibly improve the shape.
Nor will it improve exposed necks, because the margin of the veneer ends at the gum and does not restore the recession.
Nor will it stop wear. A restored tooth is covered, but the load has to go somewhere, and the opposing and the adjacent teeth begin to work differently. In a patient who grinds, restoring the four lower incisors is sometimes only the beginning of a conversation about the whole occlusion; the continuation is occlusal reconstruction in worn teeth.
A thin lower incisor with a layer of ceramic is sometimes optically thicker than the patient’s own tooth, because the material has to be fitted in somewhere; and in a smile far fewer lower teeth are usually visible than upper ones, so restoring the lower arch alone rarely changes the look of the smile the way the patient imagines. Planning should cover both arches at once. The scope of aesthetic treatment is described on the page on veneers and bonding.

Frequently asked questions
How long do veneers on lower teeth last?
There is no separate figure for the lower arch, because in studies lower veneers make up a fraction of the material. Pooled analyses of ceramic veneers give survival of 90 to 97 percent, depending on the analysis and the length of follow-up, but they describe above all the upper arch. Freedom from complications is counted separately: technical complications happen far more often than the loss of a whole restoration.
Do veneers on lower teeth debond more often than upper ones?
There is no direct comparison of the two arches in the studies, because too few lower veneers are done for them to be counted separately. What is known is that the bond with dentine is weaker than with enamel and that exposure of dentine raises the risk of failure, and on a lower incisor that scenario is more likely.
Do lower veneers require more enamel to be ground away?
Not more in quantity, because the layer ground away is of similar thickness to that in the upper arch; the trouble lies in the proportion: on a lower incisor that same layer makes up a larger part of the available enamel. That is why the preparation is carried out here under the control of silicone keys from a diagnostic wax-up, and not by eye.
What should I do if I have a bonded retainer wire on my lower incisors?
A retainer wire runs on the lingual side of the lower incisors, that is not where the veneer lies, but its presence changes the plan. For the duration of the work it has to be removed or protected, and after the restoration is placed it has to be bonded again, usually a new one, because a wire that has been taken off can rarely be positioned in exactly the same way. Removing the retention for good risks the return of crowding, so this is not a cosmetic decision.
What happens in the first weeks after lower veneers are placed?
For a few days the teeth are sometimes sensitive to cold, especially if dentine was exposed during preparation. The gum at the new margin of the restoration can be reddened for about a week. The occlusion usually needs correcting at a check-up, because the new edge meets the upper teeth differently. Sensitivity that increases instead of subsiding is a reason to contact the practice sooner.
Is a splint necessary after veneers are placed in the lower arch?
With diagnosed nocturnal grinding a hard splint is a condition, not an additional recommendation. In the observation cited, patients who ground their teeth received veneers on exactly that condition. Where there are no signs of overloading, the decision is made individually, usually after assessing wear on the opposing teeth and the tension of the muscles of mastication.
Will speech or the feel of the bite change after lower veneers are placed?
The feel of the bite changes almost always for the first few days, because the tongue immediately detects the new edge; speech usually stays unchanged, because the lower incisors take a smaller part in it than the upper ones. A persistent sense that one tooth contacts first is worth reporting, because it is an indication for correction.
Two conditions that have to come out right together
The first is enamel: how much of it is left under the planned veneer. The second is occlusion: where the contact with the opposing tooth falls, because the margin of a lower restoration works every time the teeth come together. Neither of them replaces the other, and the patient cannot measure either one. When both come out favourably, veneers on lower teeth usually hold up. When even one does not, the more honest answer is a different method, not thinner ceramic.
