A deep toothache, lingering sensitivity to heat, or a pimple-like bump on the gums can signal an infection inside a tooth. Root canal therapy removes the source of pain, disinfects the tiny internal canals, and seals the space to prevent reinfection—allowing you to keep your natural tooth. Here’s a simple, step-by-step guide to help you feel informed and at ease.
Common signs you may need a root canal
- Throbbing toothache or pain that wakes you at night
- Lingering sensitivity to hot or cold (pain lasts after the stimulus is gone)
- Swelling or tenderness in the gums; a small pimple that drains
- Deep decay, a cracked tooth, or trauma
Root canal therapy, explained
- Comfort & isolation: Local anesthetic keeps you comfortable. A small shield keeps the area clean and dry.
- Access & cleaning: We create a tiny opening, remove the inflamed or infected tissue, and shape the canals with precision instruments.
- Disinfection & seal: The canals are disinfected and filled with a biocompatible material, then sealed.
- Protection: A custom crown is often placed to reinforce biting strength and prevent cracks.
Myths vs. reality
“Root canals are painful.” Modern anesthesia and techniques make the procedure comparable to getting a filling. Most patients feel immediate relief as pressure from infection is removed.
“It’s better to extract.” Saving a natural tooth helps maintain your bite, chewing power, and jawbone stimulation. Extraction can lead to shifting teeth and additional treatment to fill the space.
Aftercare and longevity
Mild tenderness is common for a day or two and responds well to over-the-counter medication. Avoid chewing hard foods on the tooth until the final crown is placed. With a well-sealed restoration and routine care, root canal–treated teeth can last many years.
Prevention tips
- Treat cavities early—delays allow bacteria to reach the nerve
- Wear a night guard if you grind to reduce cracks
- Use a mouthguard for sports to prevent dental injuries
- Keep regular checkups to catch problems when they’re small
