TOKYO HIGH DENTAL CLINIC
Root Canal
In brief
Root canal treatment removes the infected tissue inside the tooth, disinfects it and seals it to maintain the tooth's function.
General treatment is handled by Dr. Ahn Jin-gyu, a specialist in integrated dentistry, who looks at the mouth as a whole — including alignment, the jaw joint and chewing function. The same dentist stays with you from consultation to the end of treatment.
Root canal treatment that saves the tooth
It is a treatment that removes the infected tissue and blood vessels inside the tooth, disinfects it thoroughly,
then seals it with a special material to maintain the tooth’s function.
Treatment process
PROCESS·01Checking decay/inflammation
Inflammation occurs in the tooth nerve due to decay or trauma.
PROCESS·02Removing decay/inflammation
After removing the decay and the nerve inflammation inside the root, the area is thoroughly disinfected with medication.
PROCESS·03Filling the tooth interior
After sealing the inside of the root with a special material, the empty part of the tooth crown is carefully filled with a hard dental material.
PROCESS·04Crown restoration
A tooth that has completed root canal treatment is covered entirely with dental material to finish the treatment.
We recommend this for the following
Cases where decay is severe and has progressed
into the nerve tissue inside the toothCases where the decay is deep, so removing the decayed part
risks exposing the nerve
Cases where a tooth is chipped or lost due to trauma
Cases where the nerve is damaged by gum disease
Frequently Asked Questions
Do I have to have a crown after root canal treatment?
Yes. After root canal treatment the tooth becomes weak, so it must be reinforced with a crown to last a long time.
How often should I visit the dental clinic?
For orthodontics, usually every four to six weeks; for implants, regular check-ups after surgery; and for general treatment, a check-up every six months is recommended.
