02 / UNDERSTAND YOUR CARE

What is root canal treatment?

If the pulp is infected or damaged from decay or trauma, remove internal tissue, disinfect and fill root canals to attempt to preserve the natural tooth.

Treatment continues even after pain subsides

We remove infected tissue, clean and disinfect the canals, then seal them. Stopping mid-treatment because pain decreased can lead to reinfection. Number of visits and duration vary with infection level and canal shape.

If a previously treated tooth hurts again

We check for reinfection of the canal as well as cracks, occlusion, and gum problems. Retreatment or apicoectomy may be considered, but if preservation is difficult we explain the cause and prognosis first.

Finally we protect the remaining tooth

If decay and treatment have reduced tooth structure, a crown or other appropriate restoration may be needed to reduce fracture risk. If a temporary seal is lost, contact the clinic as soon as possible to prevent bacterial entry.

Limits and precautions to know

After treatment there can be sensitivity, pain, bleeding, gum changes, or need for retreatment. Risks and recovery for each treatment method are individually explained during the consultation.

05 / YOUR QUESTIONS · 5 QUESTIONS

Questions you might have before care.

01What symptoms require root canal treatment?
Throbbing pain at rest, worse at night, severe pain to heat, or pus bags on the gum indicate pulp involvement.
02Does root canal treatment kill the tooth?
It removes infected pulp tissue and seals the canal. Internal sensation changes but surrounding tissues still have sensation; tooth can still hurt when chewing. Purpose is to preserve tooth function.
03Temporary filling fell out during root canal treatment.
If left as is bacteria can re-enter the canal. Visit as soon as possible and avoid chewing on that side until then.
04Treated tooth discoloration after root canal — why?
Discoloration can come from residual tissues, blood breakdown products or canal materials. Identify cause and consider internal bleaching or appropriate prosthesis.
05I had root canal but it hurts again.
Causes include reinfection, cracks, occlusion or gum problems. Determine cause and evaluate retreatment or apicoectomy and explain limits.
