The feeling of thin teeth is often due to enamel erosion, the gradual wearing away of the protective outer layer of your teeth. This erosion can result in increased sensitivity, a rough or sharp feeling on the tooth surface, and a generally weakened tooth structure.
Here's a breakdown of potential causes:
-
Acidic Diet:
- Frequent consumption of acidic foods and drinks (citrus fruits, sodas, fruit juices, vinegar-based dressings) softens enamel, making it more susceptible to wear.
- Example: Regularly drinking lemon water can contribute to enamel erosion over time.
-
Medication Side Effects:
- Certain medications can reduce saliva flow (dry mouth), which is crucial for neutralizing acids and remineralizing enamel.
- Without sufficient saliva, teeth are more vulnerable to acid attacks.
-
Vigorous Brushing:
- Using a hard-bristled toothbrush or brushing too aggressively can physically wear away enamel, especially at the gumline.
- It's recommended to use a soft-bristled brush and gentle circular motions.
-
Dry Mouth (Xerostomia):
- Reduced saliva production, regardless of the cause, increases the risk of enamel erosion. This can be due to medications, medical conditions (like Sjogren's syndrome), or dehydration.
-
High Sugar and Starch Diet:
- Bacteria in the mouth feed on sugars and starches, producing acids that attack enamel.
-
Bruxism (Teeth Grinding):
- Grinding or clenching your teeth, especially at night, can wear down enamel over time.
-
Friction:
- Habits like chewing on hard objects (ice, pens) can physically erode the enamel.
-
Acid Reflux Disease (GERD):
- Stomach acid that flows back into the mouth can erode enamel, especially on the back teeth.
-
Gastrointestinal Problems:
- Conditions that cause frequent vomiting can expose teeth to stomach acid, leading to erosion.
-
Genetics:
- In some cases, the thickness and quality of enamel can be influenced by genetics.
What can you do?
- Consult your dentist: A dentist can evaluate the extent of enamel erosion and recommend appropriate treatments.
- Improve oral hygiene: Use a soft-bristled toothbrush, fluoride toothpaste, and floss daily.
- Limit acidic foods and drinks: If you consume them, do so in moderation and rinse your mouth with water afterward.
- Use fluoride: Fluoride helps strengthen enamel and makes it more resistant to acid attacks. Your dentist may recommend fluoride treatments or rinses.
- Address dry mouth: Drink plenty of water, chew sugar-free gum, or use saliva substitutes.
- Manage bruxism: Your dentist may recommend a mouthguard to protect your teeth from grinding.
- Treat acid reflux: Consult your doctor to manage GERD or other gastrointestinal issues.
By identifying the underlying cause and taking appropriate measures, you can help protect your enamel and prevent further erosion.
