Dental Abrasion

Dental Abrasion – Symptoms, Causes, Treatment


Last Modified: October 30, 2023


Dental abrasion is a common dental condition that affects many individuals. It occurs when the tooth enamel is gradually worn away due to friction, typically from factors other than tooth decay or dental trauma. While dental abrasion might not be as well-known as cavities or gum disease, it can lead to dental problems and discomfort. In this article, we will explore the symptoms, causes, and available treatments for dental abrasion.

Symptoms of Dental Abrasion

  • Tooth Sensitivity: One of the most common symptoms of dental abrasion is tooth sensitivity. Affected individuals often experience pain or discomfort when consuming hot or cold foods and beverages. The exposed dentin, which lies beneath the enamel, can be particularly sensitive to temperature changes.
  • Thinning or Worn Teeth: Dental abrasion results in the gradual erosion of tooth enamel. Over time, this can cause teeth to appear thinner or worn down, with flattened biting surfaces. Such changes in tooth structure can impact the overall appearance and functionality of the teeth.
  • Notches or Grooves: As dental abrasion progresses, notches or grooves may form near the gumline or along the sides of the teeth. These areas are particularly vulnerable to erosion and can lead to further discomfort and complications.
  • Tooth Discoloration: Dental abrasion can also lead to tooth discoloration. The exposed dentin can become yellow or brown, which can be aesthetically displeasing and may cause self-esteem issues.

Causes of Dental Abrasion

  • Aggressive Tooth Brushing: One of the primary causes of dental abrasion is excessive and aggressive tooth brushing. Brushing too hard or using a toothbrush with hard bristles can gradually wear down the enamel over time.
  • Abrasive Toothpaste: Some toothpaste formulations contain abrasive particles that can contribute to enamel erosion. It is essential to choose toothpaste with non-abrasive properties and consult with a dentist to select the most suitable oral care products.
  • Poor Brushing Techniques: Inadequate brushing techniques, such as using a side-to-side motion instead of the recommended circular motion, can increase the risk of dental abrasion. It’s crucial to educate oneself on proper brushing techniques and avoid habits that can harm the teeth.
  • Teeth Grinding (Bruxism): People who grind their teeth, a condition known as bruxism, are at a higher risk of dental abrasion. The constant friction between teeth during grinding can wear down the enamel and lead to tooth sensitivity and other dental problems, which then lead to dental fillings, cosmetic dentistry, and other dental treatments.
  • Chewing Hard Objects: Chewing on hard objects like pens, ice, or fingernails can also contribute to dental abrasion. The repeated contact between hard surfaces and the teeth can erode enamel over time.
  • Acidic Diet: Consuming a diet high in acidic foods and beverages, such as citrus fruits, carbonated drinks, and certain sports drinks, can weaken tooth enamel and make it more susceptible to abrasion.

Treatment and Prevention of Dental Abrasion

  • Behavior Modification: The first step in treating dental abrasion is to identify and modify any behaviours or habits that contribute to the condition. This includes teaching proper tooth brushing techniques, discouraging teeth grinding, and avoiding the consumption of hard or acidic substances.
  • Tooth-Colored Fillings: If notches or grooves have formed due to dental abrasion, a dentist may recommend tooth-colored fillings or bonding to restore the tooth’s shape and appearance.
  • Fluoride Treatments: Dentists may apply fluoride treatments to strengthen the enamel and help reduce tooth sensitivity. Fluoride can be applied as a gel, foam, or varnish.
  • Crowns or Veneers: In severe cases of dental abrasion where tooth structure has been significantly compromised, crowns or veneers may be recommended to protect and restore the affected teeth.
  • Custom Mouthguards: For individuals with bruxism, custom-fitted mouthguards can help prevent further damage by providing a protective barrier between the upper and lower teeth during sleep.
  • Dietary Changes: Reducing the consumption of acidic foods and beverages can help protect tooth enamel from further erosion. It’s essential to maintain a balanced diet for overall oral health.
  • Regular Dental Checkups: Routine dental checkups are crucial for early detection and management of dental abrasion. Dentists can identify the condition’s progression and recommend appropriate treatments or consult with preventive dentistry.


Dental abrasion is a common dental problem that can lead to tooth sensitivity, aesthetic concerns, and functional issues. Fortunately, it is a preventable and treatable condition.

By identifying the causes and symptoms of dental abrasion and taking proactive steps to prevent it, individuals can maintain their oral health and preserve their beautiful smiles. Regular dental checkups at Clove Dental are essential to catch and address dental abrasion in its early stages, ensuring the longevity and vitality of your teeth.
