Tooth Sensitivity

Tooth sensitivity is a common dental issue where teeth become sensitive to various stimuli, including hot, cold, sweet, sour, or even breathing cold air. If you experience sharp or sudden pain, it may indicate that the nerve endings in your teeth have been activated. Understanding the causes of tooth sensitivity and how to address it is essential for maintaining your oral health and comfort.


Tooth sensitivity often occurs when the dentin, the underlying layer of your teeth, becomes exposed. This exposure can result from various factors, including:

Enamel Erosion

Enamel erosion, typically caused by acidic foods, drinks, or aggressive brushing, can lead to dentin exposure and tooth sensitivity.

Receding Gums

Gum recession, often associated with periodontal disease, can expose the roots of teeth, making them sensitive.

Gum Inflammation

Inflamed gums can soften the ligaments that support teeth, leading to tooth root exposure and sensitivity.

Cracked Teeth

Chipped or broken teeth can provide a pathway for bacteria to enter the pulp, leading to sensitivity and pain.

Teeth Grinding

Bruxism, or teeth grinding, can wear down the enamel, making teeth more sensitive.

Tooth Whiteners

Some tooth whitening products that contain baking soda or peroxide can create excessive acidity, contributing to sensitivity.


Individuals between the ages of 25 and 30 are more likely to report tooth sensitivity.

Plaque Buildup

When plaque reaches the tooth roots, it can accelerate sensitivity issues.


Certain mouthwashes with a high concentration of acid can contribute to tooth sensitivity. Consult your dentist for suitable mouthwash options.

Acidic Foods

Consumption of acidic foods like citrus, tomatoes, pickles, and teas can contribute to tooth sensitivity.

Routine Dental Procedures

Teeth may become sensitive following dental procedures, but this sensitivity is usually temporary.
