More than one tooth can be affected by hypersensitivity-which is commonly experienced when you eat or drink something that is sour, sweet or cold or hot. It is characterized usually by a pain which is sharp and shoots into your teeth’s nerve endings.
When the gums are pulled back and the underlying layer is exposed (which is called dentin), it leads to sensitivity. The dentin includes layers upon layers of the nerve endings that form the nerve centers of the teeth. These connecting layers let the trigger, such as heat or cold, to reach your nerve centers behind the teeth, leading to the pain, the reason it is called Dentin Hypersensitivity.
Here are the causes behind Dentin Hypersensitivity:
1. Brushing too hard or grinding the teeth may reduce the enamel layer, leading to exposure of the dentin and hypersensitivity.
2. Gum Diseases can also be a cause of the decay of the enamel layer leading to exposure of the dentin for prolonged periods of time leading to more sensitivity and pain.
3. Foods with high acidic content like citrus fruits and other strong drinks can result in quick erosion of the enamel layer.
4. Age also increases chances of sensitivity.
The treatments that can used to address Dentin Hypersensitivity are:
1. Rinsing with fluorides or mouthwashes that are antiseptic daily helps, along with regular flossing.
2. Avoiding highly acidic foods and drinks.
3. Try to use soft-bristled toothbrushes; they help a lot in bringing down the wearing rate of the enamel layer and help reduce sensitivity.
4. Toothpaste for sensitive teeth can be used as well as fluoridated dental products which help in recovering from hypersensitivity.
