What is Dental Erosion (Non-Carious Tooth Wear)?

Dental erosion is one of the non-carious tooth wear forms (NCCL); annual prevalence reaches 30-50% (in modern populations). It causes thin yellow-brown shading, smooth-glassy appearance, and cup-shaped erosion lesions on lingual/palatal surfaces of teeth.

Etiology: extrinsic acids (citrus, soda, sports drinks, energy drinks, vinegar, wine, lemon water habit, vitamin C tablets) - especially common with prolonged frequent consumption. Intrinsic acids: GERD, frequent vomiting (eating disorders - bulimia, anorexia, hyperemesis gravidarum, alcoholism), achalasia.

Diagnosis: BEWE (Basic Erosive Wear Examination) is the most used scoring (0: none, 1: <50% surface erosion, 2: ≥50% with no dentin involvement, 3: dentin exposure). Lesion pattern: extrinsic acid → labial/buccal surfaces, intrinsic acid → lingual/palatal surfaces (especially upper anterior teeth - 'perimylolysis' classic for bulimia). Treatment: cause elimination + remineralization (fluoride, CPP-ACP) + advanced cases composite/veneer/crown.

Symptoms

Tooth color change (yellow-brown shading)
Smooth, glassy tooth surfaces
Cup-shaped depression in molar pits
Cold-hot sensitivity (dentin exposure)
Anterior tooth length shortening
Reduced rough surface texture in restorations

Risk Factors

Frequent acidic beverage consumption (>1/day)
GERD or chronic acid reflux
Bulimia, anorexia, eating disorders
Hyperemesis gravidarum
Citrus, vinegar, lemon water habit
Vitamin C tablet use (chewable)

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Cold-hot sensitivity in tooth (especially diffuse)
  • Tooth color change (yellow-brown shading)
  • Tooth length shortening or surface smoothing
  • Frequent vomiting or reflux history
  • Acidic beverage consumption habit awareness
  • Toothbrushing immediately after vomiting (further damage risk)

Treatment Methods

01
Cause elimination (acid intake reduction, GERD treatment)
02
Topical fluoride (5% NaF varnish, 3-month interval)
03
CPP-ACP paste (Tooth Mousse, MI Paste)
04
Composite restoration (cup-shaped lesion)
05
Veneer or crown (advanced cases)
06
Mouthwash rinse (after acidic intake, fluoride mouthwash)

Impacted Tooth

Ağız ve Diş Sağlığı

An impacted tooth — most often a wisdom tooth — has not erupted fully and remains in the jaw bone or gum. It can lead to pericoronitis, caries and cysts.

Dental Implants

Ağız ve Diş Sağlığı

A dental implant is a titanium screw placed in the jawbone that supports a crown, bridge or denture, providing the closest possible function and aesthetics to a natural tooth.

Teeth Whitening

Ağız ve Diş Sağlığı

Teeth whitening lightens tooth color using hydrogen peroxide or carbamide peroxide gels. In-office (professional) bleaching uses higher concentrations with light activation for faster results; home bleaching uses custom trays with lower concentrations over 1–4 weeks. Safety depends on healthy teeth, correct concentration, isolation of gums and transient sensitivity management.

Gingival Recession (Gum Recession)

Ağız ve Diş Sağlığı

Gingival recession is the apical displacement of the gingival margin with exposure of the root surface. It may be localized or generalized and results from mechanical trauma, periodontal disease, thin biotype or anatomic factors. Recession can cause root sensitivity, caries and aesthetic concerns; management includes cause elimination and surgical root coverage when indicated.
