Root canal treatment is a modern and effective solution for saving teeth that would otherwise need to be extracted. The procedure involves removing the infected or damaged pulp from inside the tooth, thoroughly cleaning the root canals, and then filling them with a special material to prevent further infection. Once the canals are sealed, a custom-made crown is placed over the tooth to restore its strength and appearance. Root canal treatment is preferred because it helps preserve the natural tooth, avoiding the need for extraction and preventing the shifting of adjacent teeth. With proper care, a tooth that has undergone root canal treatment can last for many years, providing a long-term solution to tooth damage or infection.
