When the cavity’s too deep and the nerve, that’s inside the tooth gets inflamed, that’s when it starts hurting. That’s a lot of pain sometimes. And that’s when we need to do root canal. A lot of people seem a little scared of getting a root canal done because they think it’s very painful procedure. And sometimes they just prefer to pull the tooth out instead of saving the root canal. There’s absolutely wrong. It’s a painless, completely painless procedure. And once we numb you, you’re not going to feel the rest and then you’ll still have your tooth.
