Why Are My Teeth So Sensitive? Causes and Treatments

If sipping hot coffee or biting into ice cream makes you wince, you’re not alone. Teeth sensitivity is a common dental concern that can disrupt your daily life, but the good news is, it’s also highly treatable. At Peninsula Cosmetic and Family Dentistry in Charleston, SC, we’re here to help you understand what’s causing your discomfort and provide long-lasting relief.

Understanding Teeth Sensitivity

What is Teeth Sensitivity (Dentin Hypersensitivity)?

Teeth sensitivity, also known as dentin hypersensitivity, occurs when the inner layer of your tooth, called dentin, becomes exposed. This layer contains microscopic tubules that connect directly to the nerve of your tooth, triggering discomfort when exposed to temperature changes or certain foods.

Common Symptoms of Sensitive Teeth

• Sharp pain when consuming hot, cold, sweet, or acidic foods
• Discomfort during brushing or flossing
• Intermittent pain that comes and goes
• Sensitivity in one tooth or several teeth

What Causes Sensitive Teeth?

• Enamel Erosion: Your enamel is your tooth’s protective shield. Once it wears down, sensitivity often follows.
• Aggressive Brushing: Brushing too hard or using a hard-bristled toothbrush can wear down enamel over time.
• Acidic Foods and Drinks: Citrus, soda, wine, and other acidic substances can soften enamel and make it more vulnerable.
• Teeth Grinding (Bruxism): Grinding or clenching your teeth, especially at night, puts constant pressure on enamel, leading to wear and sensitivity.
• Gum Recession: When gum tissue pulls away from the tooth, it exposes the sensitive root surface.
• Periodontal Disease: Gum disease can damage soft tissue and supporting bone, causing recession.
• Aging: Natural aging can also cause gum recession, especially if paired with poor oral hygiene or tobacco use.

Other Potential Causes

• Tooth Decay (Cavities): A cavity exposes the dentin layer and often causes sensitivity.
• Cracked or Chipped Teeth: A break in your tooth structure can lead to exposed nerves.
• Recent Dental Procedures: Cleanings, fillings, or whitening treatments can cause temporary sensitivity.
• Teeth Whitening: Overuse of whitening products or treatments can irritate the tooth’s inner layers.

How to Treat Sensitive Teeth (At-Home & Professional Options)

At-Home Remedies for Sensitivity Relief

• Using Desensitizing Toothpaste: Formulated to block pain signals from the tooth surface to the nerve, these are often the first line of defense.
• Soft-Bristled Toothbrush and Gentle Brushing Technique: Brushing with care can help protect enamel and reduce irritation.
• Avoiding Acidic Foods and Drinks: Limiting exposure to erosive substances helps maintain enamel strength.
• Fluoride Mouthwash: Fluoride can help remineralize enamel and soothe sensitivity over time.

Professional Treatments at Peninsula Cosmetic and Family Dentistry

• Fluoride Varnish Application: We apply a concentrated fluoride solution to strengthen enamel and reduce pain.
• Desensitizing Agents: In-office treatments can seal dentin tubules and provide almost immediate relief.
• Restorative Treatments (Fillings, Crowns, Inlays/Onlays): For structurally compromised teeth, these treatments protect nerves and improve function.
• Gum Grafting (for Gum Recession): We may recommend a gum graft to cover exposed roots and reduce sensitivity.
• Root Canal Therapy (in Severe Cases): If sensitivity is due to a damaged nerve, a root canal may be the most effective solution.

Preventing Teeth Sensitivity

• Maintaining Good Oral Hygiene: Brushing twice daily with fluoride toothpaste and flossing helps prevent cavities and gum disease.
• Regular Dental Checkups at Peninsula Cosmetic and Family Dentistry: Routine visits help catch issues early and allow us to provide preventive treatments when needed.
• Dietary Considerations: Reducing acidic and sugary foods supports stronger enamel and less sensitivity.
• Addressing Teeth Grinding: Custom night guards can protect your teeth from grinding damage while you sleep.
