Deep dental cavities can progress to the pulp, causing pain, inflammation, and sometimes abscesses. In such cases, a root canal treatment is required, which involves removing the nerve from the tooth.

During the procedure, your dentist takes the necessary steps to eliminate bacteria and inflammation inside the root canal. The tooth is treated (nerve removed), rinsed, and disinfected. After this process—which may require multiple sessions—the dentist fills and seals the root canal to ensure it is airtight. In some cases, antibiotics may be prescribed to eliminate the inflammation.

Once treated, the tooth becomes more fragile, and it may be necessary to consider placing an onlay or a crown to restore and protect it.
