Symptoms of a cracked tooth.  You may experience pain in the tooth when you bite or chew. However, it probably will not happen all the time. The tooth may be painful only when you eat certain foods or when you bite in a specific way. You will not feel a constant ache, as you would if you had a cavity or abscess, but the tooth may be more sensitive to cold temperatures. If the crack worsens, the tooth may become loose.  Many people with cracked tooth syndrome have symptoms for months, but it’s often difficult to diagnose because the symptoms are not consistent.  If you are experiencing these symptoms let either the doctor or hygienists know. Ultimately the need to restore the tooth with a crown or other restorative option may be necessary.
