Drinking hot and cold beverages, eating sweet or acidic foods, brushing your teeth, breathing through your mouth, biting down\u2014if any of these normal activities are causing you pain, you\u2019re probably experiencing tooth sensitivity.<\/p>\n
Tooth anatomy helps explain why teeth can become sensitive:<\/p>\n
Sensitivity is a symptom that the tooth is compromised. You should see your dentist promptly to discover the source of and treatment for your discomfort.<\/p>\n

\nWhen a cavity is deep enough to penetrate the enamel and reach the dentin, sharp pain when eating certain foods, drinking hot or cold beverages, breathing through the mouth, or brushing can result. Sensitivity can also be a sign that a loose or broken filling needs replacement. Treating a cavity in its early stages or replacing a damaged filling right away prevents decay from reaching the inner pulp and endangering the tooth.<\/p>\n
\nOnce decay has reached the pulp, the tooth is vulnerable to infection. This infection can spread to bone and gum tissue. Because the inner pulp contains nerves, infected and inflamed pulp can be very painful. Root canal treatment<\/a> is often necessary to save the tooth.<\/p>\n
\nA chip, crack, or fracture can damage tooth structure and expose dentin and pulp to bacteria. You should see your dentist immediately after any dental trauma. Crown, onlays, veneers, or other restorations can repair injured teeth and prevent further damage.<\/p>\n
\nPeriodontitis causes the gums to pull away from the teeth, exposing portions of the cementum covering the roots. Cementum is softer than enamel, and more prone to sensitivity and decay. If you have periodontitis, your dentist can recommend treatment options, including antibiotics, deep cleanings, and\/or gum surgery.<\/p>\n
\nAcids can erode tooth enamel, exposing the dentin underneath. Acidic foods should be enjoyed in moderation and eaten with meals. Sodas and energy drinks should be limited. Medical conditions such as acid reflux can be very damaging to enamel, especially on the back of the teeth, and should be treated by your physician. Enamel won\u2019t grow back, but if you have suffered significant enamel erosion, your dentist might suggest fillings, crowns, bonding, or veneers.<\/p>\n
\nAggressive brushing and hard-bristled brushes can be so abrasive that they cause enamel erosion and gum recession. Use a soft bristled or electric toothbrush, and brush thoroughly but gently. Your dentist can recommend better brushing techniques and toothpastes which reduce sensitivity.<\/p>\n
\nRepetitive nightly grinding can put so much pressure on the teeth that the outer layer of enamel is worn away. Tiny cracks and fractures develop. Pulp inflammation can occur. A custom-fitted nightguard is a common treatment used to redistribute grinding pressures.<\/p>\n
\nToo much pressure on a tooth caused by an unbalanced bite can lead to worn or cracked teeth or pulp inflammation. Orthodontic treatment is often recommended to create a healthy, balanced bite.<\/p>\n
