What is meant by tooth sensitivity and what causes sensitive teeth?
Tooth sensitivity often leaves you with pain and discomfort while eating or drinking beverages which may be hot, cold, sour or sweet. The pain may increase further while brushing or flossing and it may become excruciating while chewing solid foods. Caring for your sensitive teeth includes the right toothpaste for your sensitive tooth and a few precautions to hurt them less.
Sensitive teeth may occur on account of the following causes:
Nerve irritation: The dentin region comprises of tiny tubes filled with fluid. When the enamel of the tooth wears down these tiny tubes become exposed, and the fluid moves to give rise to nerve irritation and subsequently causes pain when exposed to foods, cold air, touch of the tongue etc.
Excessive hard brushing: Brushing your teeth for at least two times a day for about 2 minutes each and gently moving it in the right direction is the right care your teeth need. But if you have overdone them the enamel wears off to expose the sensitive roots of the tooth.
Crack in the teeth: A minor crack or fissure in your teeth can become big enough to expose the fragile dentin leading to nerve inflammation and accumulation of germs and give rise to tooth sensitivity.
Tooth whitening agents: If you had an unnoticed impaired tooth with exposed roots tooth whitening agents like baking soda can whiten the teeth but leave behind a sensitive tooth.
Age factor: Dental experts believe that with aging tooth sensitivity occurs beginning in the mid twenties.
Untreated gum disease: An advanced gum disease left untreated can lead to tooth decay exposing the roots to cause tooth sensitivity.
Genetics: Genetically you may have sensitive teeth.
Care for your sensitive teeth:
- Ensure your toothbrush has soft bristles which cleanse your teeth and gums gently without adding to the existing pain
- Use a fluoride mouthwash regularly
- Stay away from tomatoes, citrus fruits, tea as their acidic and can worsen the pain
- Most importantly use desensitizing toothpaste with at least 5% concentration of potassium nitrate or strontium chloride.
Toothpaste for sensitive teeth:
What is meant by desensitizing toothpaste?
Desensitizing tooth pastes contain potassium nitrate or strontium chloride or a combination of the two which help to obstruct signals of pain from the enamel to the inside nerve by preventing the mobility of fluid in the tubules in the dentin of the teeth. Regular usage of a desensitizing tooth paste for a month will help to reduce the sensitivity of your teeth when exposed to sweetness, extreme temperatures etc.
