What is dental wear

Attrition, erosion, abrasion: different causes, different treatment protocols

Dental wear is not a single condition. It has at least three distinct origins: attrition (tooth-to-tooth contact wear, most commonly from bruxism or parafunctional habits), erosion (chemical dissolution from gastric acid, dietary acids, or frequent vomiting), and abrasion (external agents such as abrasive toothpaste or incorrect brushing technique). In many patients, two or three forms coexist.

This distinction has direct clinical consequences. A restoration placed without identifying and controlling the causative factor is exposed to the same dynamics that produced the wear. In patients with unmanaged bruxism, restorations, however accurately executed, undergo the same fate as the natural tooth structure they replaced.

Studio Calesini applies a sequential protocol: causal diagnosis first, stabilisation where required (occlusal device, reflux management, habit modification), then restoration.

The adhesive approach

Restoring worn teeth without sacrificing healthy tooth structure

In cases of moderate to advanced wear that has not yet irreversibly compromised coronal structure, adhesive restoration with ceramic overlays or onlays can recover form, function, and aesthetics without the aggressive preparation required by a conventional crown.

A conventional crown requires the removal of a substantial proportion of healthy tooth structure to create the space the restoration needs. In patients with worn teeth, where structure loss has already occurred pathologically, an overlay uses the space already created by wear, requiring minimal or no preparation, while bonding to residual enamel to achieve mechanical resistance comparable to that of a full crown.

For many patients quoted for full-arch crown rehabilitation, an adhesive overlay approach achieves the same functional and aesthetic outcome with significantly lower biological cost to the teeth.

Clinical criteria

When adhesive restoration
is the correct choice

Not every patient with worn teeth is a candidate for adhesive restoration. The assessment must consider residual enamel volume, the occlusal situation, and whether the causative factor has been identified and managed. These are the clinical criteria that determine the indication.

01

Moderate to advanced wear

Structural loss on occlusal or incisal surfaces with sufficient residual enamel for adhesive bonding. Absent enamel in specific zones does not exclude restoration, but modifies the preparation and adhesion strategy.

02

Causative factor managed

Bruxism managed with an occlusal device; reflux under treatment; abrasive habits modified. Restoration before stabilisation of the cause is exposed to the same forces that produced the original wear.

03

Vertical dimension assessed

In cases of generalised wear with loss of vertical dimension of occlusion (VDO), restoration involves restoring it, typically progressively, using provisional composite restorations, before fabricating definitive restorations.

FAQ

Frequently asked questions on dental wear

What is dental wear and what causes it?

Dental wear is the progressive loss of hard tooth structure from non-carious causes. The three main forms are attrition (tooth-to-tooth wear, most commonly from bruxism), erosion (chemical dissolution from gastric acid or dietary acids), and abrasion (external agents). In many patients, two or three forms coexist and require differential diagnosis before any treatment is planned.

Can worn teeth be restored without full crown coverage?

In many cases, yes. With sufficient residual coronal structure, ceramic overlays can recover form, function, and aesthetics without the aggressive preparation required by a conventional crown. A crown removes 65-75% of healthy coronal structure; an adhesive overlay uses the space already created by wear, requiring minimal or no preparation.

Does the cause of wear need to be identified before restoration?

Yes, it is essential. A restoration placed without identifying and controlling the causative factor is exposed to the same dynamics that produced the original wear. The correct protocol involves causal diagnosis, stabilisation where required, then restoration.

How long do ceramic overlays last?

Peer-reviewed literature reports survival rates above 85% at ten years with correct clinical indication, figures comparable to crown survival data over the same period. Actual longevity depends on the accuracy of the indication, the quality of execution, and management of the causative factor.

Second opinion

Have you been quoted
for full-mouth crowns?

Many patients with moderate or advanced dental wear are quoted for complete rehabilitation using conventional crowns. In a significant proportion of these cases, adhesive restoration with ceramic overlays achieves the same functional and aesthetic outcome with substantially lower biological cost.
