Restorative Dentistry : A root canal is the most necessary treatment to save your teeth from being extracted. Dentist Energy Corridor recommends root canal treatment when the bacteria inside your mouth eat out the teeth, reach the pulp chamber, and infect the pulp. During root canal treatment, your dentist will remove the infected pulp from inside the teeth, rinse out the infection, and fill out your teeth with a sealant and composite material with cavity fillings. Once your teeth are filled inside, there are minimal chances of getting affected again.
