Yes, a cracked tooth can lead to sensitivity. When a tooth cracks, it can cause a sharp pain upon biting and may also be sensitive to hot or cold temperatures. A cracked tooth can result from various factors, such as clenching or grinding teeth, biting on hard objects, or large fillings that weaken the tooth structure. Treatment for a cracked tooth depends on the severity and location of the crack, ranging from a simple filling to a crown or even root canal therapy if the nerve is affected​2​.
