Tooth Sensitivity: What Causes It and How to Treat It

Tooth sensitivity can turn simple daily activities — like drinking coffee or enjoying ice cream — into uncomfortable experiences. You’re not alone if you frequently experience sharp, sudden pain in your teeth when exposed to hot, cold, sweet, or acidic foods and drinks. Millions of people deal with sensitive teeth, but the good news is that treatments are available. At Team DDS New Carlisle, Dr. Lytha Miller and her team provide expert care to diagnose the root cause of sensitivity and offer effective solutions.

What Causes Tooth Sensitivity?

Tooth sensitivity occurs when the protective layers of the teeth wear down, exposing the underlying dentin and nerve endings. Several factors contribute to this condition, including:

• Enamel erosion – Acidic foods and drinks, aggressive brushing, and acid reflux can gradually wear down tooth enamel, making teeth more vulnerable to temperature changes and irritation.
• Gum recession – Tooth roots become exposed when gums pull away from the teeth due to aging or gum disease. Since roots lack enamel protection, they can be extremely sensitive.
• Tooth decay and cavities – When bacteria create holes in the enamel, the sensitive inner layers of the tooth become exposed, causing discomfort.
• Cracked or chipped teeth – Damaged teeth can lead to nerve irritation and increased sensitivity, especially when consuming hot or cold foods.
• Teeth grinding (bruxism) – Chronic grinding wears down enamel, increasing the likelihood of sensitivity. Many people grind their teeth unknowingly, especially at night.
• Recent dental procedures – Sensitivity after a filling, crown, or teeth whitening is common but typically temporary. If it persists, further evaluation may be necessary.

Treating Tooth Sensitivity

Addressing tooth sensitivity starts with identifying the root cause. Here are some of the most effective treatment options:

• Desensitizing toothpaste – Specially formulated toothpaste with compounds like potassium nitrate or stannous fluoride can block nerve signals and reduce discomfort over time.
• Fluoride treatments – Professional fluoride applications at Dr. Miller’s office help strengthen enamel and reduce sensitivity.
• Dental bonding or sealants – Dr. Miller can apply a protective resin to cover sensitive areas if enamel loss or exposed roots are the issue.
• Nightguards for teeth grinding – Custom nightguards can prevent enamel damage caused by grinding, reducing sensitivity and protecting overall dental health.
• Diet and oral care adjustments – Avoiding acidic foods, using a soft-bristled toothbrush, and maintaining proper oral hygiene can help prevent further enamel erosion.
