Root canal. For many people, just hearing those two words is enough to feel anxious. But here is the truth: the fear of root canal treatment is almost entirely based on outdated information — and patients who come to Tru Smile Dental Care in Muscat are regularly surprised by how straightforward and comfortable the experience actually is.

In this guide, we answer the two questions we hear most often: How long does a root canal take? and Does it hurt? We also walk you through what happens during treatment, what to expect afterwards, and when you might need one in the first place.

What Exactly is a Root Canal?

A root canal (formally called endodontic treatment) is a procedure to save a tooth that has become infected or severely decayed at its core. Inside every tooth is a soft tissue called the pulp, which contains nerves, blood vessels, and connective tissue. When bacteria reach the pulp — through deep decay, a crack, or trauma — infection sets in, causing pain, swelling, and sometimes abscess formation.

The goal of root canal treatment is to:

• Remove the infected or damaged pulp tissue
• Clean and disinfect the canals inside the tooth roots
• Shape and seal the canals to prevent re-infection
• Restore the tooth with a filling and usually a crown

Without treatment, the infection spreads, the tooth cannot be saved, and extraction becomes the only option. Root canal treatment gives your tooth a second chance — and a treated tooth can last a lifetime with proper care.

Signs You Might Need a Root Canal

Some patients present with obvious symptoms, while others have no pain at all. Common signs include:

• Severe, persistent toothache — especially when biting or chewing
• Prolonged sensitivity to hot or cold that lingers after the source is removed
• Darkening or discolouration of the tooth
• Swelling or tenderness in the nearby gums
• A persistent pimple or boil on the gum (sinus tract)
• A cracked or chipped tooth with pain
• No symptoms at all — infection found on routine X-ray

How Long Does a Root Canal Take?

The duration of your root canal depends on several factors, including which tooth is being treated and the complexity of the root canal system. Here is a general guide:

Tooth Type	No. of Canals	Approx. Duration	Visits Required
Front teeth (incisors/canines)	1 root canal	45–60 minutes	Usually 1 visit
Premolars	1–2 root canals	60–90 minutes	1–2 visits
Molars (back teeth)	3–4 root canals	90–120 minutes	1–2 visits
Complex / retreatment cases	Varies	90–150+ minutes	2 visits

At Tru Smile Dental Care, we always aim to complete root canal treatment in as few visits as possible — and for many straightforward cases, we can finish in a single appointment.

What Factors Affect Treatment Time?

• Number of canals: Molars have more canals and take longer to treat
• Degree of infection: Severe infections may require a medicated dressing before sealing
• Canal anatomy: Curved or narrow canals require more precision and time
• Your comfort: We never rush — your comfort comes first
• Restoration needed: Crown preparation may be done in the same visit or a follow-up

Does a Root Canal Hurt?

This is the question on every patient's mind — and the honest answer is: not with modern dentistry. The reputation for pain comes from an era before effective local anaesthesia and precision instruments. Today, root canal treatment at Tru Smile Dental Care is performed with:

• Powerful, long-lasting local anaesthetic — the area is completely numb before we begin
• Gentle technique and fine rotary instruments for precision and comfort
• Rubber dam isolation — keeping the area clean and your throat protected
• Continuous monitoring — we check in throughout and adjust if needed

In a 2016 study published in the Journal of Endodontics, over 90% of patients who had undergone root canal treatment reported it as painless or only mildly uncomfortable. More than 80% said they would recommend it to others.

Pain Level: Before, During & After Root Canal Treatment

Before Treatment

7–9/10

Throbbing toothache, pressure, swelling

During Procedure

1–2/10

Pressure sensation only — fully numbed

After (Day 1–3)

2–4/10

Mild soreness, easily managed with painkillers

After (Week 1+)

0–1/10

Fully comfortable, infection resolved

What Happens During a Root Canal — Step by Step

Step 1: Examination & X-ray

We take a detailed digital X-ray to assess the extent of infection and plan treatment precisely.

Step 2: Local Anaesthesia

The tooth and surrounding area are numbed completely.

Step 3: Rubber Dam Placement

A thin rubber sheet isolates the tooth, keeping it dry and protected.

Step 4: Access Opening

A small opening is made to access the pulp chamber and root canals.

Step 5: Cleaning & Shaping

Infected pulp is removed and canals are shaped using fine instruments.

Step 6: Disinfection

Antibacterial solution is used to clean the canals.

Step 7: Canal Filling

Canals are filled with biocompatible material (gutta-percha).

Step 8: Crown Placement

A crown restores strength, function, and appearance.

What to Expect After Your Root Canal

It is completely normal to experience mild soreness or sensitivity for 2–3 days after treatment. This is simply your body healing — not a sign that anything has gone wrong. Here is how to take care of yourself:

In the First 24–48 Hours:

• Take over-the-counter pain relief as directed (ibuprofen or paracetamol)
• Avoid chewing on the treated side until your permanent crown is fitted
• Eat soft foods — yoghurt, soup, scrambled eggs, mashed vegetables
• Avoid very hot or very cold food and drinks
• Do not smoke — this delays healing significantly

Signs to Contact Us Immediately:

• Severe pain that is not controlled by over-the-counter medication
• Visible swelling in the face or gums that worsens after 48 hours
• Fever or feeling generally unwell
• Your temporary filling falls out
• An allergic reaction to any prescribed medication

Common Root Canal Myths — Busted

❌ Root canals are extremely painful

✅ Modern anaesthesia makes root canals no more painful than a routine filling. Most patients are pleasantly surprised.

❌ It's better to just pull the tooth

✅ Saving your natural tooth is always the preferred option. Implants and bridges cost more and require more treatment.

❌ Root canals cause illness

✅ This myth comes from outdated research. There is no credible evidence linking root canals to systemic disease.

❌ You only need a root canal if you have pain

✅ Not always. Some infections develop silently and are detected through X-rays and examination.

❌ A root canal kills your tooth

✅ The tooth remains functional. After treatment and crown placement, it can last a lifetime.

Root Canal vs. Tooth Extraction: Which is Better?

We are often asked whether it is simpler to just pull the tooth. While extraction is sometimes necessary, root canal treatment is almost always the preferred option — for these reasons:

• Preserves your natural tooth — nothing functions as well as your own tooth
• Prevents bone loss — empty tooth sockets lead to jaw bone resorption over time
• Avoids shifting teeth — neighbouring teeth drift into gaps, affecting your bite
• More cost-effective long-term — implants and bridges cost significantly more
• No recovery time from extraction — you leave with your tooth intact
