First things first, the video claims that an average root canal begins with a standard drill to access the inside of the tooth.
Next, the dentist uses files to get in there good and get all the bad stuff out of your tooth.
Then tiny rubber cones are used with a liquid sealer in the canals to fill them back up.
Once it's all filled up, a heated instrument is used to get rid of the excess cones.
And finally, to make sure that your tooth is as strong as it can be, your dentist may put these awesome posts inside of the tooth. Then a white filling is used to fill in the spaces and hardened with a bright light.
So the other option is capping the tooth with a full crown.
