Root canal treatment is necessary when the pulp inside your tooth becomes infected or inflamed. Here are 5 signs that indicate you might need a root canal:

• Severe tooth pain when chewing
• Prolonged sensitivity to hot or cold
• Discoloration of the tooth
• Swollen gums near the affected tooth
• A persistent pimple on the gums

If you experience any of these symptoms, visit Smile Dental Hospital immediately for expert care.
