A common dental emergency that we see in our office is a cracked tooth. When teeth are extremely worn, from persistent grinding for example, they can crack under the constant pressure. During routine hygiene examinations, we check your teeth for imperfections and problems with the enamel. Most of our patients visit us infrequently during the year, so it is important that they regularly check and feel their teeth for imperfections as well. When you check your teeth regularly, you are often able to spot a problem, such as a cracked tooth.
