Teeth become sensitive when dentin, the calcified tissue of the body and part of the tooth that covers the nerve, is exposed due to enamel layer erosion or gum recession. Teeth become sensitive to temperature changes and certain foods, especially hard and sweet substances, which can lead to significant pain and discomfort.
Tooth sensitivity is a common problem today and is a product of many factors, starting with your toothpaste, toothbrush and mouthwash. What many people overlook when protecting their teeth is the source of protection. Many mouthwashes and toothpastes contain sugar while other whitening pastes contain chemical formulas that end up damaging the teeth, making them sensitive.
The next consideration should be the toothbrush where care should be taken on not using a rough, hard-bristled brush and not using your full force when brushing. This again can wear down the teeth’s protective layers.
The foods we eat plays a major role in ensuring our teeth’s health and sugary or hard foods can erode the protective enamel. Moreover, acidic foods such as oranges, tomatoes, etc, can be damaging eventually as the acid in those foods scrape away the protective coating of the teeth.
Excessive plaque or decay around the edges of the filling can wear the enamel down, just like a chipped or broken tooth can due to bacteria buildup. Moreover, if your teeth are more or less sensitive already, if not taken care of, the condition could get worse. Other than this, smoking causes gum problems which in turn affect the dentin just like gum recession. Lastly, teeth grinding teeth can weather the enamel down.
The best and most commonly understood cure for teeth is care. Proper oral hygiene in the form of daily brushing, flossing, and use of a mouthwash is mandatory, but at the same time, make sure you choose the right products.
