If you’re experiencing tooth pain or have been diagnosed with an infected tooth, you may wonder if a root canal can save your tooth. At Shiraz Endodontic Practice, we specialise in providing expert root canal treatment to help preserve and restore infected teeth. In this blog post, we will explore the process of a root canal and how it can effectively save an infected tooth.

Understanding the Root Canal Procedure

A root canal is a dental procedure performed to treat an infected tooth. It involves removing the infected pulp from the tooth’s root canal system, cleaning and disinfecting the area, and sealing it to prevent further infection. Contrary to popular belief, a root canal is not a painful procedure. It is designed to alleviate the pain caused by the disease and restore the tooth’s health.

Signs that You May Need a Root Canal

Several signs indicate you may need a root canal to save your infected tooth. These signs include:

  • Persistent toothache: If you have a severe and persistent toothache, it could be a sign of an infected tooth.
  • Sensitivity to hot and cold: If you experience heightened sensitivity to hot and cold temperatures, it may indicate an infection.
  • Swelling and tenderness: Swelling and tenderness in the gums around the infected tooth can indicate an underlying infection.
  • Discolouration of the tooth: If the infected tooth appears darker or discoloured compared to the surrounding teeth, it may be a sign of infection.
  • Pus or abscess: The presence of pus or an abscess around the tooth can indicate a severe infection.

If you are experiencing any of these symptoms, it is crucial to seek professional dental care as soon as possible to determine if a root canal is necessary.

How a Root Canal Saves an Infected Tooth

Our experienced endodontists will carefully remove the infected pulp from the tooth’s root canal system during a root canal procedure. The infected pulp contains bacteria that cause the infection and can lead to severe pain and discomfort. Once the infected pulp is removed, the root canal is thoroughly cleaned and disinfected to eliminate any remaining bacteria.

After cleaning the root canal, our endodontists fill the space with a biocompatible material called gutta-percha. This material seals the root canal, preventing further infection. In some cases, a dental crown may be placed over the treated tooth to provide additional protection and restore its strength and functionality.

Benefits of Root Canal Treatment

Root canal treatment offers several benefits for saving an infected tooth:

Pain relief: The primary goal of a root canal is to alleviate the pain caused by the infected tooth. The pain subsides once the infection is removed, and you can regain your oral comfort.

Preservation of natural tooth: A root canal allows you to preserve your natural tooth, avoiding the need for extraction. Keeping your natural tooth helps maintain proper chewing function and prevents neighbouring teeth from shifting.

Restored functionality: After a root canal, the treated tooth can function normally, allowing you to bite and chew without discomfort.

Improved oral health: By removing the infection, a root canal restores the tooth’s health and prevents the spread of bacteria to other areas of the mouth.

Frequently Asked Questions

1. Is a root canal painful?

No, a root canal procedure is not painful. Local anaesthesia numbs the area, ensuring comfort throughout the procedure. Most patients report feeling relief from pain after the infected pulp is removed.

2. How long does a root canal procedure take?

The duration of a root canal procedure can vary depending on the case’s complexity. It can take one to two appointments to complete the treatment. Our experienced endodontists will assess your specific situation and provide you with an estimated timeline.

3. Are there any alternatives to a root canal?

In some cases, the extraction of an infected tooth may be considered an alternative to a root canal. However, saving the natural tooth whenever possible is generally recommended, as it offers numerous benefits for oral health and overall well-being.

4. How long does the recovery process take after a root canal?

The recovery process after a root canal is typically minimal. For a few days, you may experience mild discomfort or sensitivity in the treated tooth, which can be managed with over-the-counter pain medication. For optimal healing, it is essential to follow your dentist’s post-treatment instructions.

5. How can I prevent future tooth infections?

Maintaining good oral hygiene practices, such as brushing twice daily, flossing daily, and visiting your dentist regularly for check-ups and cleanings, can help prevent future tooth infections. Additionally, avoiding excessive consumption of sugary foods and beverages and wearing a mouthguard during physical activities can reduce the risk of tooth infections.
