Sensitivity

When you have sensitive teeth, activities like brushing, eating and drinking, can cause sharp, temporary pain in your teeth. The most common cause is worn tooth enamel or exposed tooth roots. Some  people naturally have more sensitive teeth than others due to having thinner enamel(outer layer of the tooth that protects it).

Common causes of sensitive teeth

• Decay
• Hard toothbrush
• Grinding your teeth at night
• Regularly eating or drinking acidic foods and beverages
• Gum recession that leaves your root surface exposed
• Cracked teeth: These can become filled with bacteria from plaque and cause inflammation in the pulp of the tooth
• Plaque buildup
• Long-term use of mouthwash.
• Gastro esophageal reflux (GERD), frequent vomiting — including gastroparesis and bulimia can cause acid to come up from the stomach and esophagus, and may wear down (damage) teeth over time.

Treatment

• Desensitizing toothpaste
• Use a soft-bristled toothbrush.
• Avoid highly acidic foods.
• Use a fluoridated mouthwash daily.
• Avoid teeth grinding.

An X-ray of teeth should be done to rule out the cause or reason of sensitivity. See a dentist if using the above few suggestions doesn’t relieve your problem. Get a professional cleaning done from a dentist which will actually treat the cause as well as problem.
