At Mikula DDS, we understand that tooth sensitivity can be a frustrating and uncomfortable experience that significantly impacts your daily life. Whether you’re wincing from sharp pain when enjoying hot or cold foods, or feeling discomfort during routine teeth brushing, sensitivity can turn simple pleasures into sources of anxiety. Here’s what you need to know about the causes of tooth sensitivity and how to manage and alleviate this common dental issue effectively.
Understanding Tooth Sensitivity
Before we explore the causes and solutions, it’s crucial to understand what tooth sensitivity is. Essentially, tooth sensitivity occurs when the dentin – the layer beneath the enamel – becomes exposed. Dentin contains thousands of microscopic tubules leading to the tooth’s nerve center. When these tubules are exposed to external stimuli like temperature changes or pressure, they can trigger a short, sharp pain response.
Causes of Tooth Sensitivity
- Enamel Erosion: The enamel is your tooth’s first line of defense. This hard outer layer protects the sensitive inner structures of your teeth. However, enamel can wear away due to various factors and when enamel erodes, it exposes the underlying dentin, leading to sensitivity:
- Consumption of acidic foods and drinks
- Overzealous brushing with hard-bristled toothbrushes
- Teeth grinding (bruxism)
- Frequent vomiting (as in the case of severe morning sickness)
- Gum Recession: Healthy gums act as a protective seal around the teeth. When gums recede, they expose the tooth roots, which don’t have the same enamel protection as the crown of the tooth. Gum recession can be caused by:
- Aggressive brushing
- Periodontal disease
- Aging
- Genetic predisposition
- Tooth Decay: Cavities, especially when they progress to deeper layers of the tooth, can cause significant sensitivity. As decay erodes the enamel and dentin, it creates pathways to the nerve endings in the tooth pulp.
- Cracked Teeth: Dental fractures, even microscopic ones, can expose the sensitive inner layers of the tooth. These cracks can occur due to:
- Trauma or injury
- Biting on hard objects
- Large fillings that weaken the tooth structure
- Extreme temperature changes in the mouth
- Dental Procedures: Some dental treatments can cause temporary sensitivity that typically subsides within a few days to weeks:
- Teeth whitening treatments
- Filling replacements
- Crown placements
- Root canals
- Teeth Whitening Products: Over-the-counter and professional whitening products can cause temporary sensitivity, especially if overused.
- Plaque Build-up: Excessive plaque on the root surfaces can cause tooth sensitivity. Regular dental cleanings can help prevent this issue.
Managing and Alleviating Tooth Sensitivity
- Use a Soft-bristled Toothbrush: Switch to a soft-bristled toothbrush and adopt a gentle brushing technique. Brush in small, circular motions rather than aggressive back-and-forth strokes. This protects both your enamel and gums from unnecessary wear.
- Adjust Your Diet: Limit your consumption of acidic foods and drinks such as citrus fruits, tomatoes, wine, and carbonated beverages. When you do consume these items, rinse your mouth with water afterward to neutralize the acids. Consider using a straw for acidic drinks to minimize contact with your teeth.
- Practice Excellent Oral Hygiene: Maintain a rigorous oral care routine:
- Brush your teeth twice daily with fluoride toothpaste
- Floss at least once a day to remove plaque between teeth
- Use an antiseptic mouthwash to reduce bacteria
- Schedule regular dental check-ups and professional cleanings
- Use Desensitizing Toothpaste: These specially formulated toothpastes contain compounds that help block pain signals from the tooth surface to the nerve. Be patient – it may take several weeks of regular use to see significant improvement.
- Consider a Mouthguard: If you grind your teeth at night, a custom-fitted mouthguard can protect your teeth from further wear and reduce sensitivity. Consult with your dentist about getting a professionally made night guard.
- Apply Fluoride: Professional fluoride treatments can strengthen tooth enamel, reducing sensitivity. Ask your dentist about in-office fluoride applications or prescription-strength fluoride products for home use.
- Avoid Whitening Products Temporarily: If you’re experiencing sensitivity, take a break from whitening products until your symptoms improve. When you resume whitening, use products with lower concentrations of active ingredients and follow instructions carefully.
- Try a Salt Water Rinse: Gargling with warm salt water can help reduce inflammation and provide temporary relief from sensitivity. Mix a half teaspoon of salt in a cup of warm water and rinse for 30 seconds.
- Breathe Through Your Nose: If cold air triggers your sensitivity, try to breathe through your nose, especially in cold weather. This helps protect your teeth from direct contact with cold air.
- Explore Dental Procedures: For severe cases, your dentist might recommend:
- Dental bonding to cover exposed root surfaces
- Gum grafting to restore receded gum tissue
- Root canal for severe, persistent sensitivity
When to See Your Dentist
While some degree of sensitivity can be managed at home, it’s crucial to consult a dental professional if:
- Your sensitivity is severe or persistent
- You experience pain for more than 30 seconds after exposure to hot or cold stimuli
- You notice visible changes in your teeth or gums
- You develop new areas of sensitivity
