Filling = early damage
A filling is done when decay is limited to the enamel or dentin.
Removes the cavity
Keeps the tooth alive
Quick procedure (often 20–40 minutes)
Less pain, less cost
Tooth stays strong for years
🔥 Root canal = late damage
A root canal is needed when decay reaches the pulp (nerve).
Nerve is infected or dead
More appointments, more drilling
Tooth becomes non-vital (no blood supply)
Usually needs a crown afterward
Costs much more
Higher risk of future fracture or reinfection
⚠️ What happens if you “wait it out”
Cavities do not heal on their own. Waiting can lead to:
Severe toothache
Swelling or abscess
Spread of infection to bone or face
Possible tooth loss
🧠 Think of it like this
A filling is like fixing a small crack in your phone screen.
A root canal is replacing the screen after the phone stops working.
✅ Bottom line
Fillings preserve your natural tooth.
Root canals are damage control.
