Top 5 Causes of Tooth Sensitivity
Posted on 1/15/2025 by Neu Family Dental |
Tooth sensitivity is a common dental problem that can cause discomfort and pain. It occurs when the dentin, the inner layer of your tooth, is exposed. This can happen due to several factors, including:
1. Worn Tooth Enamel: The outer layer of your tooth is called enamel, and it acts like a protective barrier. When enamel erodes due to factors like wear and tear, acidic foods and drinks, and poor hygiene habits, it can expose the dentin beneath it, leading to sensitivity.
2. Receding Gums: The gums naturally recede over time, which can also expose the dentin. As your gum tissue pulls away, more of the root surface becomes uncovered. This exposed area is highly sensitive, causing discomfort during daily activities like eating, brushing, or even breathing in cold air.
3. Cracked Tooth: If you have a cracked or fractured tooth, it can create an opening that exposes the dentin or pulp (the innermost part of your tooth containing nerves and blood vessels). This can lead to severe pain and sensitivity to temperature, pressure, and sweets.
4. Dental Treatment: Certain dental procedures like fillings, crowns, and teeth whitening can temporarily increase tooth sensitivity. This is usually mild and goes away within a few days or weeks as the tooth heals.
5. Other Factors: Tooth sensitivity can also be caused by other factors like grinding your teeth (bruxism), certain medical conditions (acid reflux, dry mouth), or medications.
What Can You Do About It?
If you're experiencing tooth sensitivity, talk to your dentist. They can help determine the cause and recommend treatment options. Depending on the underlying reason for your sensitivity, they might suggest:
• |
Desensitizing toothpaste: These toothpastes contain ingredients that block the dentin tubules, reducing the transmission of pain signals. |
• |
Fluoride treatment: Fluoride can help strengthen your enamel and make it more resistant to wear and tear. |
• |
Gum grafting: If your sensitivity is caused by receding gums, a gum grafting procedure may be recommended to cover the exposed root surface. |
• |
Restoration Dentistry: In cases of cracked teeth or large cavities, restoration procedures like fillings, crowns, or inlays/onlays may be needed to protect the tooth and reduce sensitivity. |
• |
Mouthguards: If you grind your teeth at night, a custom-fitted mouthguard can protect your teeth and prevent further damage. |
Prevention Tips
Fortunately, many cases of tooth sensitivity can be prevented with proper oral care habits:
• |
Brush and floss regularly: Brushing twice a day and flossing once a day removes plaque and bacteria, keeping your teeth and gums healthy. |
• |
Use a soft-bristled toothbrush: Hard-bristled brushes can wear down your enamel, so choose a softer option for gentle cleaning. |
• |
Limit acidic foods and drinks: Avoid consuming large amounts of citrus fruits, sodas, and other acidic beverages, as they can erode your enamel. |
• |
Don't overuse teeth-whitening products: Overusing teeth-whitening products can make your teeth more sensitive. Follow the instructions on the product and consult your dentist for advice. |
• |
Schedule regular dental checkups: Visiting your dentist every six months for professional cleanings and checkups helps identify and address potential problems before they cause serious damage. |
By following these tips and addressing the underlying cause of your sensitivity, you can improve your dental health and enjoy a pain-free smile.
