Dental Erosion

Dental Erosion

Dental erosion is the gradual loss of tooth structure due to chemical dissolution, primarily caused by acids, without bacterial involvement. This erosion process softens and wears away the outer layer of the tooth, known as enamel, and sometimes even deeper layers.

Symptoms of dental erosion can include tooth sensitivity, especially to hot, cold, sweet, or acidic substances. Teeth might appear discolored, transparent at the edges, or have rounded or cupped indentations on the surface. In advanced stages, erosion can lead to weakened teeth, making them more prone to chipping or fracturing.

The primary cause of dental erosion is the prolonged exposure of teeth to acidic substances. Acidic foods and beverages, such as citrus fruits, sodas, fruit juices, and certain sports drinks, can contribute to erosion. Additionally, regurgitation from acid reflux or frequent vomiting associated with conditions like bulimia or gastroesophageal reflux disease (GERD) can also lead to erosion.


  • Clinical Examination: Identifying signs of enamel loss and tooth wear.
  • Patient History: Inquire about dietary habits and acid reflux symptoms.
  • pH Testing: Assess the acidity of saliva and potential erosive factors.


  • Fluoride Applications: Strengthen enamel and reduce sensitivity.
  • Lifestyle Modifications: Limiting acidic foods and beverages to minimize erosion.
  • Saliva Stimulants: Chewing sugar-free gum to promote saliva production.
  • Dental Restorations: Bonding or veneers to protect eroded teeth and improve aesthetics.

Preventing dental erosion involves minimizing exposure to acidic substances and maintaining good oral hygiene practices. Limiting the consumption of acidic foods and beverages, reducing their contact time with teeth, and using a straw when consuming acidic drinks can help minimize erosion. Rinsing the mouth with water after consuming acidic substances helps neutralize acids and minimize their effects on teeth.

Using fluoride toothpaste and mouthwash strengthens tooth enamel, making it more resistant to acid attacks. Regular dental check-ups allow dentists to detect early signs of erosion and provide guidance on preventive measures. In some cases, dentists might recommend dental bonding, sealants, or veneers to protect and strengthen eroded teeth.

Educating individuals about the impact of acidic substances on tooth enamel and promoting preventive strategies empower them to make informed choices for preserving their dental health. Understanding the causes and adopting preventive measures aids in minimizing the risk of dental erosion, ensuring stronger and healthier teeth.
