Dental Erosion: Causes, Prevention, and Treatment Explained

Teeth erosion, also known as dental erosion, is a widespread issue that affects many people worldwide. Studies show that tooth erosion impacts approximately 30–50% of baby teeth and 20–45% of permanent teeth worldwide.  Notably, there’s a discernible trend indicating a higher prevalence among males than females. This problem isn’t limited by age, with almost half of children’s teeth and nearly as many adult teeth being affected. Let’s understand what tooth erosion is and find ways to prevent it and keep our smiles healthy.

The Fundamentals of Tooth Enamel: Definition and Composition 

What is Tooth Enamel?

Tooth enamel, often known as the protective outer layer of the teeth, is a resilient substance that shields the underlying tooth structures from damage and decay. It forms the tooth’s visible surface, known as the crown, and is critical in maintaining dental health. 

Composed primarily of minerals, particularly hydroxyapatite, the enamel is one of the most complex substances in the human body. Its dense structure makes it highly resistant to wear and tear from biting, chewing, or any other daily activities. It serves as a barrier against various external factors, including erosion of teeth caused by acidic substances and other detrimental agents.

Functions of Tooth Enamel

The functions of tooth enamel are vital for maintaining overall dental health, ensuring teeth longevity, and ensuring there’s no teeth erosion. Here are the primary roles that enamel plays:

• Protection: Tooth enamel acts as a durable shield, safeguarding the inner layers of the tooth, including the dentin and pulp, from physical damage. It serves as a barrier against external forces such as biting, chewing, and grinding, preventing trauma and fractures to the tooth structure.
• Insulation: Enamel provides thermal insulation, protecting the tooth from extreme temperatures encountered while consuming hot or cold foods and beverages. This insulation helps prevent sensitivity and discomfort by minimizing the transfer of temperature changes to the inner tooth structures.
• Resistance to Wear: As the hardest substance in the human body, tooth enamel offers exceptional wear and tear resistance. It withstands the abrasive forces generated during chewing and other oral activities, maintaining the integrity and shape of the tooth over time.
• Chemical Barrier: Enamel acts as a barrier against tooth enamel acid erosion caused by acidic substances. It resists the corrosive effects of acidic foods, beverages, and oral bacteria, thereby protecting the tooth from enamel loss on teeth, decay, and cavities.
• Aesthetic Appearance: The smooth, glossy surface of enamel contributes to the aesthetic appearance of teeth, giving them a bright, white appearance. Enamel’s translucency allows light to pass through, reflecting off the underlying dentin and creating the characteristic appearance of healthy teeth.
• Bite Force Distribution: Enamel helps distribute bite forces evenly across the tooth surface, preventing excessive stress on specific areas of the tooth. This distribution of forces reduces the risk of fractures and damage to the tooth structure.

Causes of Enamel Erosion 

Causes of enamel erosion encompass various factors contributing to teeth enamel decay and teeth erosion:

• Prolonged exposure to acidic foods and beverages is what causes dental erosion, as the acids gradually wear down the protective enamel layer. 
• Poor oral hygiene like infrequent brushing or excessive teeth grinding, can exacerbate erosion. 
• Medical conditions like acid reflux and dry mouth increase acid levels in the mouth, accelerating enamel breakdown. Additionally, certain medications and genetic predispositions may play a role in enamel erosion. 

What Are The Signs of Enamel Erosion?

Signs of tooth enamel loss, often indicative of enamel erosion or dental erosion, manifest in various symptoms:

1. Sensitivity: Teeth may get sensitive to hot, cold, fizzy, or sugary foods. Advanced tooth enamel erosion symptoms can also be extreme sensitivity to temperature changes and sweet substances.
2. Discolouration: Yellowing or staining of the teeth is a common sign of enamel erosion, altering the natural appearance of the teeth.
3. Tooth Cupping: Small indentations or cups may develop on the chewing surfaces of teeth, indicating erosion and loss of enamel.
4. Cracks and Chips: Enamel erosion may result in the formation of cracks or chips on the tooth surface, compromising its structural integrity.
5. Rough Edges: Teeth may develop rough or uneven edges as the enamel wears away, affecting the tooth’s smooth texture.
6. Shiny Spots: Shiny spots on the teeth can indicate areas of enamel thinning, reflecting light differently than the surrounding enamel.
7. Increased Tooth Decay: Enamel erosion weakens the tooth’s protective layer, increasing the risk of tooth decay and cavities.
8. Altered Appearance: Teeth may appear shorter or smaller due to the gradual wearing away of enamel, altering the smile’s overall appearance.

What Are the Prevention Strategies?

Understanding teeth erosion causes is essential for implementing preventive measures and preserving enamel health. Here are some effective preventive measures:

1. Limit Acidic Foods and Drinks: Reduce acidic beverages like fruit juice and soft drinks. Instead, consume acidic foods as part of meals rather than snacks throughout the day. This minimises the frequency and duration of acid exposure to the teeth.
2. Use a Straw: While drinking acidic beverages, use a straw to direct the liquid past the teeth, limiting direct contact with the enamel. This helps reduce the amount of acid that comes into contact with the tooth surfaces.
3. Rinse Your Mouth: After consuming acidic foods or drinks, rinse your mouth thoroughly with water or a mouthwash that has fluoride. Try rinsing with a mouthwash with sodium bicarbonate or with baking soda, which can help neutralize acids and promote tooth enamel repair.
4. Practice Good Oral Hygiene: Maintain a routine. Brush your teeth at least twice every day. Use a soft-bristled toothbrush and fluoride toothpaste. Also, to remove plaque and debris from between teeth, floss daily. Stay hydrated to promote saliva production, which helps protect enamel.
5. Wear a Mouthguard: If you have a habit of grinding your teeth during sleep, wearing a mouthguard can help prevent enamel wear caused by bruxism. A properly fitted mouth guard cushions the teeth and reduces the impact of grinding, protecting enamel from damage.

Treatment of Tooth Enamel Loss

When facing eroding teeth enamel, seeking appropriate treatment is crucial to prevent further damage to your tooth structure. Unlike other body tissues, tooth enamel cannot regenerate once lost. Therefore, it’s essential to explore effective enamel erosion treatment options. Treatment options for tooth enamel loss include:

1. Fluoride Treatments: It can help restore tooth enamel and reverse early-stage cavities by promoting remineralization and strengthening enamel.
2. Fillings (Restorations): Mainly used to fill cavities caused by enamel loss, fillings restore the damaged tooth structure and prevent further decay.
3. Dental Bonding: Application of a tooth-coloured resin to the affected tooth surface, protecting damaged areas and restoring the integrity of the enamel.
4. Crowns: Dental crowns may be recommended to cover and protect extensively eroded teeth, preventing further decay and preserving functionality.
5. Veneers: In cases of significant enamel loss, veneers may be recommended, as they help restore the appearance and function of the affected teeth by covering the front surface with custom-made porcelain or composite shells.

Other treatment options for severe cases of enamel erosion may include root canal treatment or, in extreme cases, tooth extractions. It’s essential to consult your dentist for a thorough evaluation and a personalized treatment plan tailored to your specific needs. 

Conclusion

To sum up, understanding the causes, prevention, and treatment options for tooth enamel erosion is crucial for maintaining optimal dental health. By implementing preventive measures and seeking timely treatment from a qualified dentist in Sunshine Coast, such as those at Oris Dental, you can preserve enamel integrity and prevent dental complications. Invest in your smile today for a healthier tomorrow.
