Dental Abrasion: Understanding the Impact on Oral Health

Dental abrasion is a common oral health condition characterized by excessive tooth wear due to various factors such as brushing too hard, using abrasive toothpaste, consuming acidic foods and drinks, grinding teeth, and utilizing whitening products. It can lead to several dental problems, affecting both the aesthetics and functionality of your teeth.

What Is Dental Abrasion?

Dental abrasion involves wearing away the protective enamel layer of your teeth, exposing the dentin underneath. Enamel is the hardest substance in your body, but it can still wear away due to excessive friction or chemical erosion. Once exposed, dentin is more susceptible to tooth decay because it does not have fluoride protection like enamel. As dentin wears away, teeth become sensitive to hot and cold temperatures, sweets, and air pressure changes.

Common Causes of Dental Abrasion

Brushing Technique and Toothpaste Choices

Brushing too vigorously can cause abrasions as it accelerates the wearing process of dental tissues. Additionally, using toothpaste with high abrasiveness can contribute to dental abrasion. Opt for toothpaste with a low Relative Dentin Abrasive (RDA) score if you are prone to dental sensitivity, enamel loss, or recession.

Acidic Diet

Consuming acidic foods and drinks can affect your oral health. These substances lower your mouth's pH level, which increases the risk of tooth erosion and dental abrasion. Lemon juice, citric acid found in soft drinks, and sugar-free diet drinks are examples of acidic substances that can cause enamel erosion.

Grinding or Bruxism

Grinding or clenching your teeth, a condition known as bruxism, can lead to dental abrasion. This habit can wear down enamel and dentin, causing teeth to become sensitive and prone to decay. It is a common problem in people who have anxiety or are under stress.

Whitening Products

Overuse of teeth whitening products can cause dental abrasion. These products contain abrasive agents that remove stains from the surface of your teeth. However, excessive use can lead to enamel erosion and sensitivity.

Symptoms of Dental Abrasion

Increased tooth sensitivity
Yellowing or discoloration of teeth
Thinning of the teeth
Rough tooth surfaces
Red or inflamed gums

Prevention and Treatment

Prevention is the best approach to managing dental abrasion. Some ways to maintain good oral health include:

Brushing gently with a soft-bristled toothbrush
Using toothpaste with a low RDA score
Avoiding acidic foods and drinks
Refraining from grinding or clenching your teeth
Limiting the use of teeth whitening products

Treatment for dental abrasion can involve:

Applying fluoride varnish or prescription toothpaste
Replacing amalgam fillings with composite fillings
Sensitivity toothpaste
In severe cases, dental bonding or veneers

Dental abrasion can have significant consequences for your oral health. By understanding the causes and symptoms of this condition, you can take steps to prevent it and maintain a healthy, beautiful smile.
