Let’s understand ‘why’ you might need a root canal treatment. A small decay in enamel or dentin may or may not cause sensitivity or pain. However, the pulp is the most sensitive part of the tooth as it is connected to nerves and blood vessels (veins and arteries). As and when the pulp is exposed to the outer atmosphere either due to decay or an injury, you are likely to experience tremendous pain. This is exactly when a Root Canal Treatment comes to the rescue of your tooth. Through RCT, the pain can be completely eliminated without extracting the tooth.
