Do you feel a sharp, sudden flash of pain when eating hot soup, enjoying ice cream, or drinking cold water? You are not alone. Tooth sensitivity is one of the most common reasons patients visit Razia Dental Care.
Why Do Teeth Become Sensitive?
Under normal conditions, a layer of hard enamel protects the crown of your teeth. Underneath the enamel is a layer called dentin, which contains thousands of microscopic tubules leading to the tooth's nerve center (pulp). When dentin loses its protective covering, hot, cold, or acidic stimuli travel down these tubules to trigger the nerve, causing discomfort.
Common causes of dentin exposure include:
- Enamel Abrasion: Brushing too aggressively or using a hard-bristled toothbrush can wear down the enamel layer.
- Gum Recession: Periodontal disease or aging can cause the gums to recede, exposing the sensitive root surface where there is no enamel.
- Tooth Decay & Fractures: Cavities or hairline cracks in teeth allow bacteria and temperature changes to directly access the inner tooth.
- Acid Erosion: Frequent consumption of carbonated sodas, citrus fruits, and acidic food slowly dissolves enamel over time.
Professional Treatments at Razia Dental Care
If you suffer from ongoing sensitivity, Dr. Md. Razib Hossain recommends diagnostic examination to pinpoint the cause. Effective clinic solutions include:
- Fluoride Varnish: An in-office application of high-strength fluoride to reinforce enamel and seal dentin tubules.
- Dental Bonding: For exposed tooth roots due to gum recession, we can apply a tooth-colored composite resin to cover and insulate the sensitive area.
- Crowns or Inlays: If sensitivity is caused by decay or structural fractures, a custom crown will restore and protect the tooth.
- Root Canal Therapy: In severe cases where the nerve is permanently damaged or inflamed, a root canal removes the affected tissue to eliminate pain completely.
Self-Care Tips for Sensitivity
To manage sensitivity at home, swap your regular toothpaste for a desensitizing brand containing potassium nitrate, which helps block transmission of pain signals. Always use an extra-soft toothbrush and avoid brushing immediately after consuming acidic food or beverages.
