When one undergoes a root canal, the inflamed or infected pulp is removed and the inside of the tooth is carefully cleaned and disinfected, then filled and sealed. A root canal treatment is designed to eliminate bacteria from the infected root canal, prevent reinfection of the tooth and save the natural tooth.
Cavity
Cavities are permanently damaged areas in the hard surface of your teeth that develop into tiny holes. Cavities, also called tooth decay, are caused by bacteria in your mouth, frequent snacking, sipping sugary drinks, and not cleaning your teeth well.
