Enamel wear: Diagnosis

How to diagnose enamel wear

Enamel wear is gradual and can be hard to detect during the early stages. Explore the tools that can help you identify enamel wear.

Common enamel wear features

Common features of enamel wear2,3

Clinical appearance is critical to identifying enamel erosion. Over time, the wear caused by enamel erosion can lead to reduced thickness of tooth enamel and a change in the texture, shape, and appearance of the teeth, which may also cause teeth to become sensitive.2,3

These include 2,3:

  • Yellowing (advanced sign) As erosion becomes more severe, enamel thins, exposing the dentin underneath and causing teeth to appear yellow or discolored.
  • Thinning and translucency Teeth that appear thin and translucent are a sign that tooth enamel erosion may have already begun.
  • Surface changes (smoothing) One sign of dental erosion is the loss of the surface of the tooth, leading to a smooth, shiny appearance.
  • Loss of structural features (rounding) Dental erosion, if untreated, can lead to the progressive loss of the surface of the tooth. The loss of tooth structure can require complex and lengthy treatment involving fillings, veneers, crowns, and potentially root canals.

The Basic Erosive Wear Examination (BEWE)

The BEWE is a quick, effective, validated tool for assessing enamel wear4 and was a key tool in the ESCARCEL study; the first pan-European epidemiology study on non-carious cervical lesions (NCCL) and associated risk factors, and the largest and most comprehensive study of its kind.

The BEWE in practice

  • Step 1 – Talk to your patient

    How to diagnose tooth erosion

    • Your patient’s diet or dietary habits may increase their risk of erosive tooth wear.3,6 Ask them the following questions to help determine their risk:
    • How many times do you consume acidic foods or drinks in a day?
    • Do you have a history of gastric reflux?
    • Do you swish or hold acidic drinks in your mouth?
    • Do you frequently take liquid medication (which may be acidic)?
  • Step 2 – Assign BEWE scores

    Dentition divided into sextants
    • BEWE scores describe how severely each sextant of your patient’s dentition is affected by enamel wear. Each sextant should be assigned a score of 0 to 3:

    0. No erosive wear 1. Initial loss of enamel surface texture 2. Distinct defect, hard tissue loss extending over less than 50%* of the surface area 3. Hard tissue loss extending over 50%* or more of the surface area

    Once assigned, the scores from each sextant can be used to calculate a cumulative BEWE score.

    *In scores 2 and 3, dentine is often involved

  • Step 3 – Make your recommendations

    Based on your patient’s cumulative BEWE score, plan an appropriate management strategy. The table below gives recommendations for each cumulative score bracket.4

    Score (cumulative score of all sextants) Management
    None: 0-2*
    • Routine maintenance and observation
    • Repeat at 2-year intervals
    Low: 3-8*
    • Oral hygiene, dietary assessment
    • Routine maintenance and observation
    • Repeat at 2-year intervals
    Medium: 9-13
    • Oral hygiene, dietary assessment
    • Routine maintenance
    • Fluoride measures
    • Avoid restorations
    • Repeat at 3-6 months intervals
    High: 14 or over*
    • As above, with the exception of the following:
    • Consider restorations
