Follow the below given methods to reduce your tooth sensitivity:
Change the way you brush
Avoid acidic foods and drinks
Fruit juices, acidic foods such as oranges, pickles, red wine attack your enamel. Limit these foods and drinks. Do try to brush your teeth after 20 minutes of having them.
Desensitizing agents such as fluoride varnish or even plastic resins can be applied to the sensitive areas of your teeth. This will help in reducing your tooth sensitivity.
Toothpastes that contain salts such as KNO3 block dentinal tubules, thereby reducing tooth sensitivity. All these toothpastes are available in market. But make sure that you consult your dentist first.
Maintain good oral hygiene
Continue to brush properly for thorough cleaning of your teeth and mouth.
This is a good home remedy and proves helpful in reducing pain.
If you have some gum recession cause by hard brushing or by gum disease then the root will be exposed and cementum will be worn away.
Everyone does not find sensitive tooth pastes work. Use high fluoride content mouthwashes to reduce your tooth sensitivity.
