A cracked tooth can be difficult to detect, but early symptoms should never be ignored. Many patients experience tooth sensitivity when chewing or pain with hot and cold temperatures, which may come and go at first. Even small cracks can worsen over time, allowing bacteria to enter the tooth and increasing the risk of infection, severe pain, or tooth loss. Prompt evaluation by a dentist is key to determining the extent of the crack and choosing the right treatment, which may include monitoring, a dental crown, or other restorative care. If you notice changes in how a tooth feels or pain when biting, scheduling a dental exam can help protect your oral health and prevent more complex procedures down the road.
