Difference Between RCT and Filling – Which Do You Need?
When you have a toothache, one common question patients ask is – “Do I need a root canal or just a filling?”. Both treatments are effective, but they work for different dental problems. As a dentist, I want to help you understand the difference between RCT and filling so you can make the right decision for your oral health.
What is a Dental Filling?
A dental filling is a simple procedure used to treat minor cavities or tooth damage. The dentist removes the decayed part of the tooth and fills it with materials like composite resin, amalgam, or glass ionomer. Fillings restore the tooth’s shape, strength, and function.
When Do You Need a Filling?
- Small cavities detected early
- Minor cracks or chips
- Wear and tear on teeth
- No infection in the tooth pulp
What is a Root Canal Treatment (RCT)?
Root Canal Treatment is a procedure to save a tooth when the pulp (nerve) inside is infected or inflamed. During RCT, the dentist removes the infected pulp, cleans and disinfects the canals, and seals them to prevent further infection.
When Do You Need a Root Canal?
- Severe toothache, especially when biting
- Sensitivity to hot and cold lasting long
- Swelling or pus near the tooth
- Deep decay reaching the pulp
Difference Between RCT and Filling
| Aspect | Filling | Root Canal |
|---|---|---|
| Purpose | Repairs minor tooth decay or damage | Treats infection inside the tooth pulp |
| Procedure Time | 30–60 minutes | 1–2 hours, may need multiple visits |
| Pain Level | Usually painless with local anesthesia | Done under anesthesia, mild soreness after |
| Cost | Lower | Higher |
| Tooth Life After Treatment | Several years if maintained | Can last a lifetime with a crown |
How to Decide Which One You Need?
Only a dentist can confirm whether you need a filling or a root canal after examining your tooth and taking X-rays. If the decay is shallow, a filling is enough. However, if the decay has reached the nerve, an RCT is necessary to save the tooth and avoid extraction.
