Mouthwash: Some people just overdo it when it comes to using their mouthwash. If you are rinsing your mouth with this solution several times per day, you risk developing sensitive teeth.This mainly happens because the greatest majority of mouthwashes contain certain acids that make the sensitive teeth issue worse. Make sure you use a mouthwash that contains neutral fluoride.
Acidic Foods: When you consume plenty of fruit juices, tomatoes and other acidic foods the enamel on your teeth will start eroding. When the enamel gets thinner, more of the dentin becomes exposed and your teeth will become more sensitive.Stay away from over-consuming these acidic foods, and also make sure to rinse your mouth with plain water after consuming these foods to avoid the attack of the acids on your teeth. Also, you can neutralize acids in your mouth by consuming a piece of cheese after meals.
