Which is the softest and softest layer of teeth?

Pulp is the innermost and softest layer of teeth. It contains living tissue (blood and nerves) that descends below the gum line along with dentin. If a cavity reaches the pulp, root canal therapy may be necessary to remove the infection and save the tooth. If the tooth can’t be saved, it may need to be extracted.
