Tooth sensitivity can occur for various reasons, including:
Enamel erosion: The enamel, the outer layer of the tooth, can wear down due to acidic foods and drinks, aggressive brushing, or conditions like acid reflux. This exposes the dentin underneath, which is sensitive to temperature changes and acidic substances.
Gum recession: When the gum tissue around the teeth pulls back, it can expose the sensitive root surfaces of the teeth, leading to sensitivity.
Tooth decay (cavities): Holes or cavities in the teeth expose the inner layers of the tooth, which can lead to sensitivity, especially to hot or cold temperatures.
Fractured teeth: Cracks or fractures in the teeth can expose the dentin and cause sensitivity, particularly when biting or chewing.
Dental procedures: Sensitivity can occur after certain dental procedures such as tooth whitening, fillings, or crown placement. This sensitivity is usually temporary but can persist for some time.
Grinding teeth (bruxism): Grinding or clenching the teeth can wear down the enamel and expose the dentin, leading to sensitivity.
Toothbrush abrasion: Brushing too hard or using a toothbrush with hard bristles can wear down the enamel and cause sensitivity.
Dental conditions: Conditions such as gum disease or cracked teeth can contribute to tooth sensitivity.
Excessive plaque: Plaque buildup on the teeth can lead to tooth decay and gum disease, both of which can cause sensitivity.
It's essential to see a dentist if you experience tooth sensitivity to determine the underlying cause and receive appropriate treatment.
