I Have a Cavity and It Hurts: Do I Need a Root Canal Treatment?
June 1, 2025
What's Really Going On Inside a Cavity?
A cavity starts small. It's just a tiny hole in your tooth's hard surface. But beneath that hard shell lies a sensitive layer called dentin. Go deeper, and you'll find the pulp—the nerve center of your tooth. When decay breaks through to the pulp, it sparks inflammation, pain, and sometimes infection. This is when the toothache stops being a nuisance and starts affecting your daily life. Signs your cavity is serious:- Pain that lingers, even when you're not eating.
- Sensitivity to hot, cold, or sweet foods.
- Swelling around the gums.
- Discoloration of the tooth.
- A small bump (abscess) on the gums.
Toothache vs. Root Canal Pain: What's the Difference?
Not every toothache screams "root canal." Some are mild irritations; others demand urgent care. Here's a simple way to tell:- Mild discomfort: Could be early-stage decay or gum irritation.
- Sharp, shooting pain: Might be a cracked tooth or deep cavity.
- Throbbing, pulsating ache: Often linked to pulp infection, which calls for root canal therapy.
Can't I Just Get a Filling Instead?
Great question. Fillings are perfect for small to moderate cavities. They restore the tooth after the decayed part is removed. But when decay reaches the nerve, a filling won't stop the infection. Covering an infected pulp with a filling is like putting a band-aid over an infected wound. It won't heal the source of the problem. Root canal therapy is the go-to solution when:- The pulp is infected or inflamed.
- There's an abscess.
- Pain is persistent and severe.
Why You Shouldn't Wait to See a Dentist
We get it. No one loves dental visits. However, delaying treatment can turn a simple procedure into a bigger issue. Ignoring an infected tooth risks spreading bacteria to your jawbone, bloodstream, and even your heart. Besides health risks, the pain will only intensify. Early intervention is key. The sooner you see a local dentist or a dentist in Crofton, MD, the easier (and less painful) the treatment.How Root Canal Therapy Saves Your Tooth
Here's what happens during a typical root canal:- The dentist numbs the area—no ouch!
- They get rid of the infected pulp and clean the canals.
- The space is filled with a biocompatible material.
- Finally, a crown is placed to restore strength and function.
What If I Don't Get a Root Canal?
Avoiding treatment might seem tempting, but it has consequences:- The infection could spread.
- You might end up needing an extraction.
- Bone loss around the tooth could occur.
- Replacement options (like implants) are costlier and more invasive.
