A fitting hole is then punched in the dam only leaving the infected tooth to protrude through it. The dam will isolate the infected tooth from the rest of the mouth. This creates an environment that is free of saliva and bacterial contamination found in the mouth.
Step3: Drilling an access hole
A tiny hole is drilled through the top of the affected tooth. It can also be drilled from the front or behind the tooth to get access to the root canal and pulp chamber.
Step 4: Remove diseased pulp tissue
Through the access hole, the diseased pulp tissue and nerves are carefully removed with special instruments.
Step 5: Disinfecting and shaping the canals
Once the pulp is removed, an antibiotic or antiseptic solution is used to disinfect the canals. After that, the canals are appropriately shaped using a special flexible dental instrument.
Step 6: Selecting a root canal filling and doing the filling
The root canal is then filled and sealed with a rubber-like material called “gutta-percha.” Proper sealing of the root canal is highly recommended to prevent reinfection.
Step 7: Cementing a crown
A crown is then cemented to restore the lost tooth structure and protect the entire tooth from re-infection.
Step 8: Post Care
An antibiotic is normally prescribed to prevent infection. However, when you feel any discomfort such as mild soreness, it is recommended to use mild painkillers to relieve the discomfort.
