What is a Root Canal?

What Is a Root Canal?

A root canal is a procedure used to treat a tooth infection, damage inside a tooth, or a cavity that has reached the tooth nerve.
– Each tooth contains a hollow space filled with nerves and blood vessels called the pulp.
– If the pulp becomes infected or dies due to decay or injury, it can cause pain, pressure and swelling at a tooth.
– A root canal removes the damaged areas, disinfects the space, and seals it to prevent reinfection in an effort to save the tooth.

Your Appointments

Root canal treatment may be completed in one or two appointments:

First Appointment:
– Your dentist numbs the area for comfort.
– The infected tissue is removed and the space is cleaned.
– Medication may be placed to reduce bacteria.
– A temporary filling seals the tooth.

Second Appointment (if needed or completed at first appointment):
– The temporary filling is removed.
– If the infection is under control, the dentist fills the space with a permanent material.
– This step prevents bacteria from returning and completes the root canal.

After the Root Canal

Once the root canal is finished:

– Most patients experience relief from pressure and discomfort.
– The tooth is still functional but may be more brittle.
– A crown is needed to protect the tooth from cracking or further decay.
– Schedule your follow-up to restore the tooth with a build-up filling and a crown.

Post-Op Instructions

For a smooth recovery, follow these steps:

– Take all antibiotics as prescribed until completed—do not stop early.
– Use over-the-counter pain medication like ibuprofen (600 mg every 6–8 hours for 3–5 days), unless advised otherwise.
– Rinse with warm salt water (1 tsp salt in 1 cup warm water) several times a day.
– Do not chew on the treated side until tenderness subsides.
– Avoid flossing around the treated tooth unless cleared by your dentist.
– Skip carbonated beverages for the first 24 hours.
– If the temporary filling wears down or falls out, call us.

What to Expect During Healing

After treatment:

– Mild soreness or sensitivity may last up to a week.
– The tooth may feel slightly different from others during healing.
– The body needs time to heal the bone around the tooth roots.
– If pain worsens or swelling continues, contact us.

Why a Crown Is Needed

– The tooth no longer has blood supply and may become more brittle.
– A crown strengthens, covers, and protects the tooth from breaking.
– Root canal-treated teeth will require a crown due to prior decay or large restorations.
– Schedule this follow-up within a few weeks of treatment completion.
