Dental sensitivity is the discomfort of the teeth in one or more teeth that is triggered by hot, cold, bittersweet foods and drinks, or even by breathing cold air. The pain can be sharp, sudden and shoot deep into the nerve endings of the teeth.
Dental sensitivity occurs when the underlying layer of your teeth, the dentin, is exposed as a result of the retreat of the gum tissue (the protective blanket that covers the roots of the teeth). The roots, which are not covered by a hard enamel, contain thousands of small tubules that lead to the nerve center of the tooth (the pulp). These tubules (or channels) of the dentine allow stimuli, for example, hot, cold or sweet foods, to reach the nerve of your tooth, which causes the pain you feel.
There are many factors that can lead to the development of dental sensitivity, including.
Brush too hard. Over time, brushing too hard or using hard bristles toothbrush it can abrade the enamel and cause dentin exposure. It can also cause the recession of the gums (the gum tissue is removed from the teeth).
Recession of the gums. As the gums recede from a tooth due to conditions such as periodontal disease, the surface of the root is exposed. Gum disease (gingivitis). The inflamed and sore tissue of the gums can cause sensitivity due to the loss of the supporting ligaments, which exposes the surface of the root that leads directly to the nerve of the tooth. Cracked teeth Chipped or broken teeth can fill with bacteria from the plaque and enter the pulp causing inflammation. Abrasive teeth Squeezing or tightening the teeth can abrade the enamel and expose the underlying dentin. Products for whitening teeth or toothpaste with baking soda and peroxide. These products are the main contributors to the sensitivity of the teeth. Your age. The tooth sensitivity is higher between 25 and 30 years.
Plate accumulation. The presence of plaque on the root surfaces can cause sensitivity.
Use of mouthwash. The long-term use of some mouthwashes. Some over-the-counter mouth rinses contain acids that can worsen tooth sensitivity if you have exposed dentin (the middle layer of the tooth). The acids further damage the dentin layer of the tooth. If you have sensitivity to dentin, consult your dentist about the use of a neutral fluoride solution.
Acidic foods Regular consumption of foods with a high acid content, such as citrus fruits, tomatoes, pickles and tea, can cause enamel erosion.
Recent routine dental procedures. Sensitivity can occur after cleaning the teeth, smoothing the root, crown Placement, and dental restoration. The sensitivity caused by dental procedures is temporary, usually disappears in 4 to 6 weeks.
Maintain good oral hygiene. Continue with proper brushing and flossing techniques to thoroughly clean all parts of your teeth and mouth.
Use a soft bristle toothbrush. This will result in less abrasion of the toothbrush on the tooth surface and less irritation on the gums. Brush gently and carefully around the gum line so that no more tissue is removed from the gum. Use desensitizing toothpaste. There are several brands of toothpaste available for sensitive teeth. With regular use you should notice a decrease in sensitivity. You may need to try several different brands to find the product that works best for you. Other tip Spread a thin layer of toothpaste over exposed tooth roots with your finger or a Q tip before going to bed. Do not use a tartar control toothpaste; Instead, use a fluoride toothpaste. Watch what you eat. Frequent consumption of highly acidic foods can gradually dissolve tooth enamel and cause exposure to dentin. They can also aggravate sensitivity and start the pain reaction. Use fluorinated dental products. Daily use of a fluorinated mouth rinse may decrease sensitivity. Ask your dentist about products available for home use. Avoid the grinding of the teeth. If you grind or squeeze your teeth, wear a mouth guard at night. Consult your dentist at regular intervals. Get professional dental cleaning, oral hygiene instructions and fluoride treatments every 6 months.

White fillings (adhesives) to cover exposed root surfaces Fluoride varnishes applied to the exposed root surface Dentin sealants applied to the exposed root surface
