Saving your tooth,
not pulling it
Precisely treating the infected inside of the tooth to preserve your natural tooth.
Root canal (endodontic) treatment – DIAN Dental natural-tooth-preserving care
The last and most important choice
to save your natural tooth
When a tooth hurts badly, it’s natural to fear it must be pulled. But no matter how far implants advance, they can’t perfectly replace the chewing feel and unique value of a natural tooth that fits your own body.
Root canal treatment cleanly removes irreparably damaged, infected tissue inside a tooth from decay or trauma and seals the space with a safe material — preserving the natural tooth without extraction.
Beyond just relieving immediate pain, DIAN treats from the foundation up so you can keep your natural tooth for life.
If you have these symptoms, root canal treatment is urgent.
(* The longer a nerve infection is left, the more it dissolves the bone around the root, so prompt diagnosis and treatment are needed.)
A 4-step process — a precise procedure done carefully over an average of 3–4 visits.
STEP 01 3D digital precision diagnosis
3D and anatomical diagnosis
We accurately analyze the size of the inflammation at the root tip and the shape of the canals — invisible to the eye — with 3D CT to secure a safe treatment path.
STEP 02 Canal cleaning, shaping & disinfection
Removing infection & shaping canals
We cleanly remove the infected, pain-causing nerve tissue with precision instruments, then clean the narrow, complex canals and thoroughly sterilize them to prevent reinfection.
STEP 03 Gap-free canal filling (sealing)
Biocompatible sealing
Once bacteria are fully removed and the canals are clean, we densely fill them with a special biocompatible material leaving no empty space, blocking any reinvasion by outside bacteria.
STEP 04 Tooth reinforcement & crown restoration
Finishing with a crown
After a root canal, the tooth loses its nutrient supply and can crack easily (like dead wood). We fill the inside with a strong core, then place a crown to fully restore normal chewing function and strength.
The questions patients ask most about root canals (FAQ)
A. The treatment removes the already-infected nerve that causes pain, so once it begins the severe pain actually goes away. At DIAN, from the anesthesia stage we use pain-relief systems (topical and painless anesthesia) so you can be treated comfortably. Don’t worry — please come in.
A. Yes, absolutely. A root-canaled tooth loses its water and nutrient supply and becomes very dry and brittle — like dead wood that snaps at the slightest impact. If you use it without a crown and it splits vertically, the tooth can’t be saved and you’ll need an implant, so you must finish with a crown.
