How do I know if I need a root canal?
Tooth decay is a widespread issue, with research showing that 92% of adults experience cavities at some point in their lives. In severe cases, decay can lead to an infection in the tooth’s nerve, necessitating a root canal. This procedure involves removing the infected nerve, thoroughly cleaning the tooth’s interior, and sealing it to prevent further issues.
Understanding Tooth Structure
Beneath the hard enamel exterior, each tooth contains a soft inner layer called dental pulp. This pulp is rich in blood vessels that nourish the tooth. Additionally, nerves run through the root canal, connecting the root to the pulp and enabling the tooth to sense temperature changes.
Signs of Nerve Infection
When the dental pulp or nerve tissue is damaged, bacteria multiply rapidly inside the tooth, often resulting in an abscess—a pus-filled pocket near the root. Symptoms of an infected nerve include:
- Severe pain or sensitivity when biting or applying pressure
- Prolonged sensitivity to hot or cold temperatures
- Discoloration or darkening of the affected tooth
- A recurring pimple-like bump on the gums
- Swelling or tenderness in the gums
- Facial, neck, or head swelling
These infections can stem from deep decay, repeated dental work, facial injuries, large fillings, or cracks in the tooth.
Steps to Take If a Root Canal is Needed
A dental professional is the only one who can understand and decide if a root canal is necessary. Through an oral examination and X-rays, your dentist will do an assessment of the condition of the tooth and confirm if there is an abscess or infection. If a root canal is what is required, the dentist will:
- Create a small opening in the tooth.
- Remove the infected pulp and nerve tissue.
- Thoroughly clean and fill the tooth’s interior.
- Seal the opening with a protective compound to prevent reinfection.
The procedure is performed by giving local anesthesia to make sure of comfort.
