Maybe: Heat sensitivity does not necessarily mean you need a root canal. Depending on the length of time the heat sensitivity lasts and how it responds to heat compared to other teeth you may or may not need a root canal. Dentists will also look at other factors such as if the tooth is sensitive to biting pressure or tapping on it.
