Dental abrasion is the pathological wearing away of teeth due to abnormal processes, habits or abrasive substances. This condition is most commonly associated with over vigorous toothbrushing and abnormal habits.
- Over vigorous brushing
- Use of hard tooth brush
- Improper brushing technique
- Abrasive technique
- Biting a pipe stem
- Biting finger nails
- Opening bobby pins
Dental abrasion may results in:
- Tooth Hypersensitivity
- Compromised esthetics
- Risk of tooth fracture
- Pulpal damage
- Poor periodontal health
1.Dentin Desensitization: This is a viable option for those situations where minimal amount of dentin is exposed(<1mm) and the patient experiences hypersensitivity. This may be managed by:
- Fluoride varnishes or Fluoride iontophoresis
- Dentin-bonding agents
- Use of Desensitizing tooth pastes
2.Restorations: They are indicated when there is:
- Considerable loss of enamel and dentin
- Esthetics are compromised
- Deep lesions affecting strength of the tooth
- Caries in cervical lesion
- Severe Hyper-Sensitivity
Restorative materials of choice are:
- Glass ionomer cement
3.Endodontic Therapy: When cervical abrasion is extensive and involving the pulp, then root canal treatment is indicated followed by full coverage restoration in the form of crown.
4.Periodontal Therapy: Periodontal therapy is indicated when non-carious cervical lesion is associated with gingival recession and mucogingival defects.
- Root coverage procedures using free gingival graft or connective tissue grafts.
- Root coverage using non-grafting procedures like rotational and coronally advanced flaps or guided tissue regeneration.
