Worn, shortened or chipped teeth change not only the appearance of the smile — they also change the way the upper and lower teeth meet during biting. That is why a smile makeover for worn teeth rarely consists simply of applying veneers. In people over 40, it is usually a combination of restoring appearance and function that has to be planned in the right order. In this article we explain in plain language where to start: why the first step is checking the bite (how the teeth meet each other), and not, for example, choosing the colour of the new teeth. We show the three stages of treatment — from diagnosis, through testing the new bite, to the final restoration — and explain which steps cannot be safely skipped. 

Worn teeth are a problem of function, not only of appearance

Where should a smile makeover for worn teeth begin? With a diagnosis. Tooth wear (the gradual loss of the hard tissues of the tooth) slowly lowers the crowns, changes the bite and shortens the lower part of the face. First the cause must be established and correct function restored, and only then should appearance be addressed.

Teeth usually wear for several reasons at once. The first is tooth-on-tooth friction (attrition), common in people who clench or grind their teeth, especially at night (bruxism). The second is the action of acids that dissolve enamel (erosion) — from an acidic diet or from the reflux of stomach contents (reflux). The third is wear from external factors (abrasion), for example overly hard brushing.

The consequences are not only a matter of appearance. Shortened teeth can lower the vertical dimension of the bite (the distance between the upper and lower jaw when the teeth are together), cause sensitivity and small cracks in the enamel and, over time, change the facial features and overload the jaw joints. That is why we treat worn teeth as a problem of function, not merely of “beautifying” the smile.

The first signs are easy to miss: flattened, worn tooth surfaces, translucent or chipped edges of the front teeth, small cracks in the enamel, sensitivity to cold, sometimes the impression that the teeth are getting shorter or that the bite has changed. People who grind their teeth often hear about it from those close to them. The sooner you report these symptoms, the more healthy tooth tissue can be preserved and the smaller the extent of the later restoration.

Who often thinks about such a makeover

The typical patient is a person over 40 in whom wear has built up over the years — because of grinding, an acidic diet, reflux, or several of these causes at once. They notice shorter, yellowed or “tired” teeth, sometimes sunken features around the mouth. The reason for coming is usually twofold: a wish for a nicer smile and a wish to be rid of sensitivity and to bite comfortably.

This is a patient who wants a lasting, predictable result. That is precisely why such a restoration requires careful planning — the more complex the treatment, the more important it is not to skip any stage of the diagnosis. Here a good appearance is the crowning of well-restored function.

Why function and the bite come first, and appearance only afterwards

The order is not a formality — it determines the durability of the result. If new, attractive restorations are built on an incorrect bite, they will take on the same forces that destroyed the natural teeth. In a large review of studies on full-arch restoration in people with moderate and severe wear, it was precisely fracture of the restoration that was the most common problem — regardless of the material used (Fan et al., 2025).

That is why, before the final restorations are made, it is worth first testing the new bite in a reversible way — that is, one that can be undone. In one reported case, temporary overlays slipped onto the teeth without preparing them (so-called Snap-On PMMA) were used to check the new vertical dimension, speech and appearance, and only the approved arrangement was transferred to the final restorations (Tasopoulos et al.). This principle of “check first, then make it permanent” can be the essence of a safe makeover.

The three stages of a makeover for worn teeth

The safe route can be divided into three stages, which are not carried out simultaneously or in any order. In our practice in Wola, the Modern Dental & Orthodontics team begins with a full assessment of function, and the aesthetic design is created only on a stable bite.

Stage 1 — Diagnosis: what has worn and why

We begin by establishing the cause and extent of the wear. This includes a conversation about habits (grinding, an acidic diet, reflux, medications taken), an examination in the surgery, assessment of the jaw joints, photographs, a scan or models of the teeth and, if needed, X-rays and tomography (detailed 3D imaging, so-called CBCT). At this stage the dentist resolves the most important question: whether the vertical dimension needs to be raised, or the restoration can be carried out without it.

Assessment of the bite covers how the teeth meet in occlusion and during movements of the jaw, as well as how much space is genuinely missing after the wear. 

Stage 2 — Stabilisation and testing: a reversible trial of the new smile

Before anything is prepared, the cause of the wear is brought under control — for example, with a night splint in the case of grinding, or a change of diet and treatment of reflux in the case of erosion. Then a design of the new teeth is created (digitally or in wax), transferred to the mouth as a try-in (mock-up) and temporary restorations. This allows the patient to “wear” the new shape and height of the teeth, and the dentist to fine-tune the bite before the final work.

Stage 3 — Restoration: appearance and function together

Only now are the final restorations made: onlays (thin restorations covering the biting surface, so-called overlays), veneers, crowns or a combination of these — from composite or ceramic. The previously tested bite arrangement is transferred to the final work, which increases the predictability of the result. The modern approach favours solutions that preserve healthy tooth tissue wherever possible.

The restoration is usually carried out in sequence — first the bite is restored in the posterior segments, which carry the greatest chewing forces, and then the front teeth responsible for appearance. This order protects the new work against overload. After completion, a protective night guard is often recommended, especially in people who grind their teeth.

What cannot be skipped

A significant mistake is skipping the diagnosis and the trial stage for the sake of a quick result. The table below shows what each stage is for and what risks its omission carries. The order is not a matter of the dentist's taste — it follows from mechanics: the new work must be built on a bite that has first been diagnosed, stabilised and tested.

Stage	What it is for	Risk of skipping it
Diagnosis of the bite and the cause of wear	Establishing why the teeth have worn and whether the vertical dimension needs to be changed	A restoration built on a still- active problem — recurrent wear and fracture of the work
Bringing the cause under control (grinding, acids)	Halting the process destroying the teeth	New restorations destroyed just like the natural teeth
Trial stage (design, try-in, temporary work)	A reversible test of the new bite, speech and appearance	Irreversible preparation for an untested bite
Final restoration	Durable transfer of the approved plan to the final work	Lack of predictability and a shorter lifespan of the restorations

Methods of restoration — from composite to ceramic

Once function has been stabilised, the material and technique are chosen. Tissue-preserving restoration of worn teeth includes composite (a resin-based material, applied directly or as a ready-made restoration) and ceramic (including lithium disilicate and zirconia), often in the form of overlays on the biting surface. In the review by Fan et al. (2025), such treatment gave good results in people with moderate and severe wear.

Figures help to understand the differences between materials. In the same review, the estimated annual failure rate was around 0.64% for directly applied composite, 0.13% for so- called resin nanoceramic and 0.04% for ceramic — the lowest precisely for ceramic. The authors note, however, that traditional composite in the posterior teeth performed worse than the other solutions. A similar conclusion emerges from a study comparing ceramic with composite at a raised vertical dimension: the ceramic wore markedly more slowly, although it required slightly more preparation of the tooth (Burian et al., 2021).

In practice, such low rates mean that well-made ceramic work serves most patients for many years. No material, however, is resistant to the effects of uncontrolled grinding — which is why we always think about durability together with controlling the cause of the wear, not in isolation from it.

The conclusion for the patient is not that “ceramic always wins”. The choice of material depends on the extent of the wear, the force of the bite, the presence of grinding and expectations regarding appearance. In some people the best option is a combination of techniques — ceramic overlays at the back and veneers at the front — chosen individually to fit the diagnosis.

It is worth understanding the logic of “preserving tissue”. Classic crowns require considerable preparation of the tooth; onlays and veneers often make it possible to rebuild worn surfaces while preserving more healthy tissue. With worn teeth, where tissue is already scarce, every saved millimetre matters for the prognosis. Crowns are reserved for the most damaged teeth or those after root canal treatment.

Sometimes, however, the best first step is not a restoration but orthodontics. In some patients a small movement of the teeth — for example, with clear aligners — makes it possible to regain the space lost to wear and to carry out the later restoration more conservatively. This is not a solution for everyone, but it illustrates well that the plan should follow from the diagnosis, not from a single favourite method.

The role of digital planning and the trial stage

A digital smile design combines a scan of the teeth, photographs of the face and — if needed — tomography into a single model. It allows the shape and position of the teeth to be designed in relation to the facial features, and then this design to be transferred to the mouth as a try-in and temporary restorations. The patient sees the anticipated result before deciding on the final work.

Reversibility is the most important thing. In the case mentioned, temporary overlays made it possible to check the vertical dimension, speech and appearance without interfering with the teeth, and after approval to transfer the tested arrangement to the final ceramic work (Tasopoulos et al.). For the patient, this is a chance to “try on” the new smile before decisions are made that cannot be undone. It must be remembered, however, that temporary materials wear more quickly and serve only for the trial period, not permanently (Doumit et al., 2025).

How long a makeover takes and what to realistically expect

This is a process spread over stages, not a single visit. The diagnosis and planning alone are usually several visits, the trial stage on temporary restorations — from a few weeks to a few months, and the final restoration a further set of visits, depending on the number of teeth. In most patients a considered trial stage reduces the risk of adjustments at the end.

Honesty about the limitations is part of a good plan. The result can be spectacular, but its durability depends on controlling the cause (e.g. wearing a splint in the case of grinding), hygiene and check-up visits. The final extent — from single onlays to a full restoration — depends on the individual diagnosis and cannot be reliably determined without an examination.

The makeover does not end on the day the work is fitted. Durability is built afterwards: regular check-ups make it possible to assess the condition of the restorations and the bite and to catch overload in time. In people whose cause was grinding or acids, it is precisely consistency — wearing a splint, hygiene, fewer acidic drinks — that most often decides whether a beautiful smile will last for years.

What affects the extent and cost of treatment

The extent — and with it the time and cost of treatment — depends on several specific factors that are established only after the diagnosis. The most important are: the number of teeth to be restored, the depth of the wear, the need to change the vertical dimension (which usually means working on both dental arches), the choice of material (composite or ceramic), the need for preliminary treatment (e.g. root canal treatment, gum treatment or protection against grinding) and the extent of digital planning.

Treatment is carried out in stages, which allows it to be spread over time and decisions to be made step by step. A sound plan and estimate are drawn up after the consultation and assessment of the bite — only then can the dentist present the real scope of the work, rather than rough ranges detached from the individual diagnosis.

How to prepare for the first visit

A well-prepared first visit speeds up planning and makes it more accurate. Before the consultation it is worth gathering some information that will help the dentist establish the cause of the wear more quickly:

• A list of medications taken and general health conditions (including reflux, rheumatic diseases, eating disorders).
• Observations regarding grinding or clenching of the teeth — including comments from those close to you about grinding at night.
• Dietary habits that promote erosion: acidic drinks, citrus fruits, energy drinks, wine, frequent snacking.
• Earlier X-rays and documentation from previous treatment, if available.
• Your own photographs of your smile from years ago — they help to recreate the natural shape and proportions of the teeth.
• A list of expectations and questions regarding the result, durability and course of treatment.

Such a set of information makes it possible to talk straight away about the safe order of the stages, and not only about the appearance of the teeth.

Key takeaways

• Start by checking the bite and the cause of the wear, not by choosing veneers — this is the foundation of the whole makeover.
• Function and the vertical dimension first, appearance afterwards — not the other way round.
• The trial stage on temporary restorations is a reversible test of the new smile — it helps to avoid irreversible mistakes.
• Ceramic wears the most slowly, but the choice of material always depends on the individual situation.
• A lasting result requires controlling the cause of the wear and regular check-up visits after the restoration is completed.

Frequently asked questions

Where should a smile makeover for worn teeth begin?

With checking the bite and establishing the cause of the wear, not, for example, with choosing a colour or veneers. The dentist assesses grinding, the effect of acids, the vertical dimension and the condition of the joints, and then plans the order of treatment. Only on a stable functional foundation is the aesthetic part designed — this translates into the durability of the result.

Can veneers be placed on worn teeth straight away?

Usually this is not optimal. Veneers placed on an incorrect bite take on the forces that destroyed the natural teeth, and fracture more often. First the cause of the wear is established and the new bite is tested on temporary work, and the final aesthetic restorations are made at the end of the process.

How does a smile makeover differ from an ordinary aesthetic restoration?

A makeover for worn teeth combines appearance with the restoration of function — it includes control of the bite, a possible change in its vertical dimension and a trial stage. An ordinary aesthetic correction concerns healthy, properly functioning teeth. With wear, skipping the functional layer shortens the lifespan of even the most attractive restorations.

Do you have to wear a splint before the restoration?

It depends on the cause of the wear. In the case of grinding, controlling the bite forces — often with a night splint — can be a condition for the durability of the future work. Where the action of acids predominates, a change of diet and treatment of reflux are more important. The need for and type of protection is decided by the individual diagnosis, not by a set formula.

How long does the whole smile makeover for worn teeth take?

It is a multi-stage process. Diagnosis and planning are several visits, the trial stage on temporary work usually lasts from a few weeks to a few months, and the final restoration takes a further set of visits depending on the number of teeth. A considered trial stage lengthens the planning but increases the predictability and durability of the outcome.

Do worn teeth always require crowns?

No. The modern approach prefers tissue-preserving solutions — onlays (overlays) and veneers — wherever the extent of the wear allows. Crowns are reserved for heavily damaged or root- treated teeth. The extent of the restoration is chosen individually on the basis of the diagnosis, the force of the bite and the patient's expectations.

How much does a smile makeover for worn teeth cost?

The cost cannot be reliably given without an examination. It depends on the number of teeth being restored, the depth of the wear, the need to change the vertical dimension, the material chosen and the extent of preliminary treatment. Treatment is carried out in stages, and a detailed plan and estimate are presented after the consultation and assessment of the bite, individually for the given patient.

Is restoring worn teeth painful?

Most stages are carried out under local anaesthesia, and the tissue-preserving approach limits the extent of tooth preparation. The trial stage on temporary work is painless and reversible. Temporarily, you may feel yourself getting used to the new bite or experience sensitivity, which usually subsides; further management is decided by the treating dentist.
