What is root canal treatment and when do I need one?
Root canal treatment removes infected or inflamed tissue (the pulp) from inside a tooth, usually caused by deep decay, a cracked tooth, or repeated dental work. It's needed when the pulp is damaged beyond healing but the outer tooth structure can still be saved — the usual alternative is extraction.
What does Dr. Harris actually do during a root canal?
As an FCPS-qualified endodontist, Dr. Harris numbs the area, isolates the tooth, then cleans out the infected pulp from inside the root canals using fine instruments under magnification. He shapes and disinfects the canals, fills them with a biocompatible material, and seals the tooth. In most cases he'll also recommend a crown afterward to protect the treated tooth from cracking under normal biting force.
Is root canal treatment painful?
The procedure is done under local anesthesia, so patients typically feel pressure rather than pain during treatment. Some mild soreness for a day or two afterward is normal and manageable with over-the-counter pain relief; severe or worsening pain afterward should be reported to the clinic.
How many appointments does it take?
Most root canals at One Dental Co. are completed in one to two visits, depending on how complex the tooth's canal system is and whether active infection needs to settle first.
Do I need a crown after a root canal?
In most back teeth (molars and premolars), yes — a crown is strongly recommended because a root-canal-treated tooth becomes more brittle and can crack under chewing pressure without one. Front teeth sometimes only need a filling, depending on how much natural tooth structure remains.
How much does root canal treatment cost?
Cost depends on the tooth's location, how many canals it has, and whether a crown is needed afterward. Call or WhatsApp the clinic with your symptoms or an X-ray and the team can give you an accurate quote.
How long does a root-canal-treated tooth last?
With a proper crown and normal oral hygiene, a root-canal-treated tooth can last for decades — often a lifetime. Regular check-ups help catch any issues early.
Can a root canal fail, and what happens then?
Occasionally a treated tooth can become reinfected, usually from a missed canal, a new crack, or a leaking filling or crown. This can often be resolved with retreatment (redoing the root canal) rather than extraction, which Dr. Harris assesses case by case.
