Tooth decay is the process of damage to a tooth, while a root canal is a treatment procedure performed because of severe tooth decay or infection.
Here's a breakdown:
Tooth Decay (Cavities)
- What it is: Tooth decay, also known as cavities or dental caries, is the breakdown of tooth enamel.
- Cause: Primarily caused by bacteria in the mouth that produce acids from sugars and carbohydrates.
- Progression:
- Starts with enamel erosion.
- Progresses to dentin (the layer beneath enamel).
- Eventually can reach the pulp (the innermost part of the tooth containing nerves and blood vessels).
- Symptoms:
- Tooth sensitivity to hot or cold.
- Pain when eating or drinking something sweet.
- Visible pits or holes in the teeth.
- Toothache.
- Treatment:
- Early stages: Fluoride treatments.
- More advanced stages: Fillings (removing the decayed portion and filling the space).
- Severe decay: Root canal or extraction.
Root Canal
- What it is: A dental procedure to treat infection or severe decay that has reached the pulp of the tooth.
- Why it's needed: When decay reaches the pulp, bacteria can infect the nerves and blood vessels, causing pain, inflammation, and potentially an abscess.
- Procedure:
- The dentist removes the infected or damaged pulp.
- The inside of the tooth is cleaned and disinfected.
- The space is filled and sealed.
- A crown is often placed on the tooth to protect it and restore its function.
- Purpose: To save a tooth that would otherwise need to be extracted. It eliminates infection and relieves pain.
Key Differences Summarized
Feature | Tooth Decay | Root Canal |
---|---|---|
What it is | The process of tooth damage. | A treatment to save a tooth with infected or severely decayed pulp. |
Cause | Bacteria producing acid from sugars. | Infection or severe decay reaching the pulp. |
Action | A destructive process. | A restorative procedure. |
Treatment Goal | To stop the decay and restore the tooth with a filling. | To remove infection, relieve pain, and save the tooth. |
Severity | Can range from minor enamel erosion to deep pulp involvement. | Indicates advanced decay or infection. |
In short, tooth decay is the problem, while a root canal is often the solution when that problem has progressed to a severe stage affecting the tooth's pulp.
