Sensitive Teeth: Why It Happens and What to Do About It

A sharp pain when eating ice cream, sipping hot coffee, or even brushing your teeth can range from annoying to severely limiting your quality of life. Sensitive teeth are incredibly common, but often manageable once you understand the underlying cause. At Bonin Dental Care, we identify why your teeth are sensitive and implement solutions that genuinely work.

Dentin Exposure: The Root Cause

Healthy teeth have enamel covering the crown and cementum covering the root. Underneath is dentin, a porous material containing microscopic tubules that connect to the nerve at the tooth’s center. When dentin becomes exposed, stimuli reach the nerve, causing pain.

Dentin exposure occurs when you lose the enamel or cementum that normally protect it. This can happen through multiple mechanisms, and identifying which applies to your situation guides treatment.

Gum Recession: The Most Common Cause

Gum recession exposes the root surface, which is covered in cementum rather than enamel. Cementum is softer and less protective than enamel, making exposed roots particularly sensitive.

Gum recession happens for several reasons. Aggressive brushing with a hard toothbrush over years gradually pushes your gum line downward. Tobacco use damages gum tissue and accelerates recession. Gum disease causes gum loss as infection destroys gum and bone. Orthodontic tooth movement can sometimes cause recession if teeth are moved to the extent that the gum margin recedes.

If you notice your teeth look longer than they used to or see a dark line at your gum line, gum recession is likely occurring. Contact Bonin Dental Care for evaluation because untreated recession worsens over time.

Enamel Erosion: Acid Damage

Acidic foods and beverages dissolve enamel directly through chemical action, independent of bacteria. Citrus fruits, sodas (including diet sodas), sports drinks, and fruit juices are major culprits. Acidic vomit from eating disorders or GERD (reflux) also erodes enamel.

When enamel erodes, dentin becomes exposed and sensitivity results. The erosion is permanent because enamel doesn’t regenerate.

Minimizing acid exposure by drinking acidic beverages with meals, using a straw to bypass teeth, and rinsing with water after consuming acidic foods helps prevent further erosion.

Enamel Wear from Grinding

Teeth grinding creates tremendous force that wears away enamel over time, exposing dentin. Grinding-related sensitivity often accompanies other grinding symptoms like jaw soreness and flattened tooth surfaces.

A night guard protects against further wear and prevents additional sensitivity from developing.

Cavities and Cracked Teeth

Cavities create small holes in enamel that expose dentin underneath. Cracked teeth similarly expose dentin in the crack area. Both cause localized sensitivity and require professional treatment to remove decay or repair the crack.

If sensitivity is localized to one or two teeth, cavity or crack investigation is important. Untreated cavities progress and can eventually require root canal treatment.

Aggressive Brushing and Hard Toothbrushes

Using a hard toothbrush or brushing too vigorously gradually wears away enamel and gum tissue. Many people unconsciously brush too hard, thinking aggressive brushing cleans better. In reality, soft bristles with gentle technique clean as effectively while protecting your teeth.

Switching to a soft toothbrush and using gentle brushing technique prevents further damage. An electric toothbrush set to its standard (not intense) setting can be gentler than vigorous manual brushing.

Treatment Options for Sensitive Teeth

Desensitizing toothpaste contains compounds that block stimuli from reaching the nerve. These pastes require consistent use and work better for mild sensitivity. For more severe cases, desensitizing paste helps but might not eliminate sensitivity completely.

Professional fluoride gel or bonding materials applied by Dr. Bonin can seal exposed dentin, blocking stimuli more effectively than toothpaste alone. These treatments sometimes provide immediate relief but might need periodic reapplication.

For sensitivity from gum recession, gum grafting might be considered in severe cases to restore recession and cover exposed roots.

Long-Term Management

Identifying and addressing the cause is crucial. If sensitivity stems from acidic foods, modifying consumption patterns prevents further damage. If grinding causes sensitivity, a night guard stops progression. If aggressive brushing is the culprit, technique adjustment prevents worsening.

Once you’ve addressed the cause, desensitizing toothpaste and fluoride treatments help manage existing sensitivity. For many people, the combination of addressing the cause plus using desensitizing products provides excellent relief.

Prevention Strategies

Avoid acidic foods and drinks, or consume them strategically with meals using a straw. Don’t brush immediately after acidic exposure because your enamel is temporarily softened. Wait 30 minutes before brushing.

Brush gently with a soft toothbrush and proper technique. If you grind your teeth, use a night guard. Maintain excellent oral hygiene to prevent decay that creates sensitivity. Address gum disease promptly because it leads to recession and sensitivity.

When Professional Treatment Is Needed

If desensitizing toothpaste doesn’t provide adequate relief after consistent use for several weeks, professional treatment is warranted. Dr. Bonin can apply stronger fluoride products or bonding materials that provide better results than toothpaste alone.

If sensitivity is sudden or severe, investigate the cause. Sharp, localized sensitivity might indicate cavity, crack, or newly receded area requiring treatment.

Addressing Underlying Issues

Sometimes sensitivity is the symptom that prompts discovery of other problems. Newly sensitive teeth might be the first sign of cavity development or gum disease. Localized sensitivity might reveal a crack that needs attention.

This is why dental evaluation is important when sensitivity develops. Dr. Bonin can identify whether sensitivity is from benign causes like enamel wear or whether it’s signaling a problem needing treatment.

Relief Is Possible

Sensitive teeth don’t have to limit your life. With identification of the underlying cause and appropriate treatment, most people achieve excellent symptom relief. Whether through desensitizing products, professional treatments, addressing the cause, or a combination approach, sensitivity is very manageable.

Contact Bonin Dental Care if you’re experiencing sensitive teeth. Dr. Bonin will identify what’s causing your sensitivity and implement an effective treatment plan. Relief is likely much closer than you think.
