Although your tooth enamel is the strongest substance in the body, it is not indestructible. Your teeth experience a lot of wear and tear. Just with the number of times we eat per day, our teeth get a lot of use. As with anything that gets used frequently, there is always the possibility of a problem developing. This is one of the reasons we are so passionate about our patients visiting us for routine hygiene examinations and cleanings. During these appointments, we inspect the teeth for signs of decay and other problems. One of the issues we look for is cracked teeth.
