Enamel erosion is a dental condition which occurs when the outermost layer of the teeth, known as enamel, gradually wears away over time. Enamel is the hardest substance in the human body and protects against tooth decay and damage. However, various factors can weaken enamel and lead to erosion, compromising the strength and integrity of the teeth. Learn what enamel erosion is, its causes, symptoms, and strategies for prevention.

What is Enamel Erosion?

Enamel erosion occurs when acids in the mouth wear away the mineralized outer layer of the teeth. While enamel is highly resistant to acids, it can be damaged by frequent exposure to acidic drinks and foods, as well as certain medical conditions and oral habits. Over time, enamel erosion may lead to tooth discoloration, tooth sensitivity and an increased risk of cavities and tooth decay.

Causes of Enamel Erosion

Several factors can contribute to enamel erosion, including:

Acidic Foods and Beverages: Consuming acidic food items, such as citrus fruits, sodas, sports drinks, and fruit juices, can expose the teeth to acids that weaken enamel over time.

Acid Reflux and GERD: Gastroesophageal reflux disease (GERD) and chronic acid reflux can result in stomach acids travelling up into the mouth, where they can erode tooth enamel.

Dry Mouth: Reduced saliva production, often due to certain medications, medical conditions, or dehydration, can increase the risk of enamel erosion by reducing the mouth’s natural ability to neutralize acids and remineralize the teeth.

Bruxism (Teeth Grinding): Constantly clenching or grinding the teeth, a condition known as bruxism, can wear down enamel over time and contribute to enamel erosion.

Certain Medical Conditions: Medical conditions such as eating disorders (e.g., bulimia nervosa), acid reflux, and gastrointestinal disorders can increase the risk of enamel erosion due to frequent exposure to stomach acids.

Poor Oral Hygiene: Inadequate oral hygiene practices, such as infrequent brushing and flossing, can allow plaque and bacteria to accumulate on the teeth, leading to acid production and enamel erosion.

Symptoms of Enamel Erosion

The symptoms of enamel erosion can vary depending on the severity of the condition. Common signs and symptoms include:

  • Increased tooth sensitivity, especially to hot, cold, sweet, or acidic foods and beverages.
  • Discoloration of the teeth, with areas appearing yellow, translucent, or discoloured.
  • Rounded or worn edges on the teeth.
  • Cracks, chips, or indentations on the tooth surface.
  • Tooth pain or discomfort, particularly when biting or chewing.

Prevention of Enamel Erosion

While enamel erosion can be concerning, there are steps you can take to help prevent it from occurring:

Limit Acidic Foods and Beverages: Reduce your consumption of acidic foods and beverages, or consume them in moderation. Try to rinse your mouth frequently with water after consuming acidic items to help neutralize acids and minimize their effects on enamel.

Maintain Good Oral Hygiene: Brush your teeth twice daily with fluoride-containing toothpaste and floss regularly to remove plaque and bacteria from the teeth. Consider using a soft-bristled toothbrush and avoiding abrasive toothpaste to minimize enamel wear.

Stay Hydrated: Drink lots of water throughout the day to help maintain a healthy saliva flow and rinse away food particles and acids from the mouth.

Use Fluoride Products: Use fluoride mouthwash or fluoride treatments recommended by your dentist to strengthen enamel and protect against decay.

Address Underlying Health Conditions: If you have medical conditions such as acid reflux or GERD, work with your healthcare professional to manage symptoms and reduce the risk of enamel erosion.

Wear a Mouthguard: If you constantly grind your teeth at night, consider wearing a mouthguard while sleeping to protect or limit your teeth from damage and minimize enamel erosion.

Seeking Dental Care

If you experience symptoms of enamel erosion or are concerned about your teeth’s health, it’s essential to schedule regular dental check-ups. Your dentist can assess the condition of your enamel, identify any signs of erosion or decay, and recommend appropriate treatment and preventive measures.

Remember to practice good oral hygiene, limit acidic foods and beverages, and seek dental care as needed to preserve the strength and integrity of your enamel. Contact us to schedule your dental visit today.
