Step 1- Anesthesia
A surface anesthetic spray or jelly is applied on the area to be injected so that the anesthetic injection becomes painless. After waiting for a couple of minutes the anesthetic is administered to numb the area.
Step 2- Removing the decay of the tooth
Now that the tooth is numb, a high speed drill is used to remove the decayed portion of the tooth without any pain.
Step 3- Creating an access
A small opening is created in the tooth to access the pulp of the tooth.
Step 4- Removing the pulp
Removing the pulp eliminates the infection & hence the pain too.
Step 5- Cleaning & shaping of the root canal
Mechanical debridement of the root canal system is done with small instruments and washed away with disinfection solutions to make the tooth germ free.
Step 6- Obturation
The space inside the root canal is filled with a material called gutta-percha and sealed so that the system should not get infected again.
Step 7- Post endodontic rehabilitation
Now that the tooth is infection free and sealed, the cavity is filled with a restorative material like cement, composite or a silver filling.
