Sugar is supposed to be one of the best things in life, but there are numerous health concerns that come from eating too much sugar. Tooth problems are one of these concerns. Sometimes when we bite into a sugary sweet, you may notice that your teeth register a painful, almost delicate-to-the-touch sensation. This is known as dentin hypersensitivity. Some people are more prone to this condition than others, but it can eventually affect all of us as we age. Dentin sensitivity is most commonly associated with sucrose, and the main reason for this is that the enzymes in sucrose can easily penetrate the tooth enamel and create sensitivity to the exposed nerves. This is even more likely if your enamel is eroding or has been completely wiped away from your teeth. The sharp pain and uncomfortable sensation are caused by osmosis, which is the movement of your saliva with sucrose across a permeable membrane, which in this case, is the dentin on your teeth. There is no cure for this, and if you are experiencing very painful dentin hypersensitivity, book an appointment with your dentist.
