Poor Oral Hygiene
Sometimes, your sensitive teeth is caused by a lack of oral hygiene. There is a reason you are supposed to brush your teeth after meals and floss at least once a day. It’s to protect your teeth from the sugars and acids and plaque buildup that will inevitably ensue. When there is excessive plaque buildup on the teeth, it will begin to dissolve the enamel. As you already know, without your enamel, your teeth are defenseless.
You should also give attention to fillings, since the edges are prone to decay throughout the years.
