There is no need to worry. Before the procedure begins, the dentist administers local anesthesia, ensuring that you remain comfortable throughout the treatment. At Siam Dental Clinic, we also use advanced dental technology to enhance precision, shorten treatment time, and minimize discomfort as much as possible.

The duration depends on the complexity of each tooth. In general, treatment requires 1–2 visits, with each appointment lasting approximately 1–1.5 hours. The dentist will evaluate your condition and provide a clear treatment timeline from the first visit.

A crown is strongly recommended, especially for posterior (back) teeth, as teeth that have undergone root canal treatment tend to become more brittle and prone to fracture. A dental crown helps protect the tooth and ensures long-term strength and functionality.

When performed correctly and combined with good oral hygiene, a tooth that has received root canal treatment can last many years—often decades.

Preserving a natural tooth is always preferable to extraction. Natural teeth are stronger and play an essential role in maintaining proper bite alignment and chewing function. Tooth replacement options, such as dentures, should be considered only when the natural tooth can no longer be saved.
