When tooth decay or infection penetrates deep into the nerve chamber of a tooth, root canal therapy may be necessary to save it. Severe decay, fractures, injury, or gum disease can allow bacteria to invade the inner pulp of the tooth, leading to inflammation and infection. Common symptoms include sensitivity to heat or cold, gum swelling, persistent pain, or a constant bad taste in the mouth. Left untreated, the infection can spread, causing abscesses, bone deterioration, and even systemic health issues like heart disease or stroke.

The good news is that root canal therapy can stop the infection, relieve pain, and preserve your natural tooth. During this procedure, Dr. Hashemian removes the infected tissue, sterilizes the nerve chamber, and seals the tooth to prevent future infection. A custom-made crown is then placed to restore strength, structure, and appearance—allowing your tooth to look and feel completely natural again. Root canal therapy not only saves your tooth but also protects your overall health.

Frequently Asked Questions About Root Canal Therapy

How do I know if I need a root canal?

Signs include severe tooth pain, sensitivity to temperature, gum swelling, or a persistent bad taste in your mouth. A dental exam and X-ray will confirm whether a root canal is needed.

Is a root canal painful?

Modern root canal therapy is virtually painless. Local anesthesia ensures comfort throughout the procedure, and most patients report that it feels no different from getting a regular filling.

What happens during a root canal?

Dr. Hashemian removes the infected pulp, cleans and sterilizes the inside of the tooth, and seals it. A custom crown is then placed to strengthen and restore the tooth’s appearance.

How long does a root canal take?

Most root canal treatments can be completed in one to two visits, depending on the severity of the infection and the complexity of the tooth.

Will I need a crown after a root canal?

Yes. A crown reinforces the treated tooth, restoring its strength and preventing future damage while maintaining a natural appearance.

With proper care, a root canal-treated tooth can last a lifetime. Good oral hygiene and regular dental visits are key to its longevity.

What happens if I don’t get a root canal?

Without treatment, the infection can spread, leading to abscesses, bone loss, and even systemic health complications. The tooth may also eventually fall out.
