Root Canal Treatment in Islamabad: Relief From Hot and Cold Sensitivity

A sip of hot chai or a spoonful of ice cream should not make you wince. If one tooth keeps aching long after something hot or cold has touched it, the nerve inside may be inflamed or infected, and it rarely settles on its own. Root canal treatment in Islamabad can often stop that lingering pain and save the tooth, so you can eat and drink normally again. Many patients delay treatment because they fear the procedure, but with modern anesthesia most people find it far more comfortable than the toothache that brought them in. The key is getting the tooth assessed early.

What is root canal treatment?

Root canal treatment is a procedure that removes inflamed or infected pulp, the soft tissue containing nerves and blood vessels, from inside a tooth. The dentist cleans and shapes the canals, fills and seals them, and then restores the tooth with a filling or crown so it can keep working like a natural tooth.

You can read more about the procedure itself on our root canal treatment page and in our guide on what root canal treatment involves.

Why hot and cold sensitivity can signal a nerve problem

Not every sensitive tooth needs a root canal. Brief sensitivity is common and often comes from worn enamel, exposed roots, or a small cavity. What matters is how long the pain lasts.

According to Cleveland Clinic, sensitivity that fades quickly is typical of reversible pulpitis, where the nerve can usually recover once the cause is treated. Sensitivity to heat, cold, or sweets that lasts more than a few seconds is more typical of irreversible pulpitis, where the nerve is unlikely to heal and root canal treatment or extraction is usually needed.

Signs that your tooth may need assessment for a root canal include:

Pain from hot or cold that lingers for several seconds or longer after the trigger is gone
Throbbing pain that starts on its own, especially at night
Pain when biting or pressing on the tooth
A tooth that has darkened in color
Swelling or a small pimple-like bump on the gum near the tooth
A deep cavity, a large old filling, or a crack in the tooth

In our Islamabad clinic, we often see patients who have been chewing on one side for weeks to avoid a painful tooth, or who have been taking painkillers every few hours just to get through the workday. By the time they come in, the nerve is frequently already beyond repair. Earlier visits can sometimes mean a simpler filling is enough.

Who is a good candidate for root canal treatment in Islamabad?

Root canal treatment is often recommended when:

The pulp is inflamed beyond recovery (irreversible pulpitis)
The pulp has died or become infected, with or without an abscess
A deep crack or trauma has exposed the nerve
There is enough healthy tooth structure left to rebuild the tooth afterward

Root canal treatment may not be the right fit when:

The tooth is cracked vertically down into the root, which usually cannot be repaired
Too little tooth structure remains to support a filling or crown
Advanced gum disease has left the tooth loose with little bone support
The tooth has no role in chewing or your bite, and your dentist advises that extraction is more sensible

If your dentist feels the tooth cannot be saved predictably, they will explain your options, including extraction and replacement. Our article on root canal treatment vs extraction walks through how that decision is usually made.

How root canal treatment works at DentoCorrect

Treatment is usually completed in one to three visits, depending on the tooth and whether infection is present. A typical visit looks like this:

Examination and diagnosis: your dentist asks about your symptoms, tests the tooth's response to cold and tapping, and takes an X-ray to see the roots and surrounding bone.
Local anesthesia: the area is numbed so you feel pressure rather than sharp pain.
Isolation: a thin rubber sheet keeps the tooth clean and dry during treatment.
Cleaning and shaping: the inflamed or infected pulp is removed, and each canal is cleaned, disinfected, and shaped.
Filling and sealing: the canals are filled with a rubber-like material and sealed to help prevent reinfection.
Restoring the tooth: a filling, and often a crown for back teeth, is placed to protect the tooth and restore chewing.

Mild soreness for a few days afterward is common and usually settles with simple over-the-counter painkillers. The American Association of Endodontists notes that most patients describe the procedure as feeling similar to getting a routine filling, and that saving your natural tooth is generally the preferred option over extraction.

How long does a root-canal-treated tooth last?

With a good restoration and regular care, a treated tooth can often last many years. A long-term study published in Clinical Oral Investigations followed 598 root-canal-treated teeth for up to 37 years and reported tooth survival of about 97% at 10 years and 81% at 20 years (López-Valverde et al., 2023). Healthy gums and protecting the tooth from heavy grinding were linked with better long-term outcomes.

To help your treated tooth last:

Get the final filling or crown placed promptly after treatment
Avoid chewing hard foods on the tooth until it is fully restored
Brush twice daily and clean between your teeth every day
Wear a night guard if your dentist says you grind your teeth
Keep up regular checkups so your dentist can monitor the tooth

Root canal cost in Islamabad

The cost of root canal treatment depends on several factors:

Which tooth is treated, since molars have more canals than front teeth
How severe the infection is and how many visits are needed
Whether the tooth needs a crown afterward
Whether additional X-rays or retreatment of an old root canal are required

For context, published prices from Islamabad clinics in 2026 commonly start at around PKR 8,000 to PKR 25,000 per tooth, and can be higher for complex molars or when a crown is included. When comparing quotes, it is worth asking whether the crown and follow-up visits are included.

The most accurate way to know your cost is a consultation, where your dentist can examine the tooth, take an X-ray, and give you a clear treatment plan.

Frequently Asked Questions

Does root canal treatment hurt?

Root canal treatment is done under local anesthesia, so most patients feel pressure rather than sharp pain during the procedure. Many find it similar to having a filling. Some tenderness for a few days afterward is common and usually eases with over-the-counter painkillers. The toothache that leads to treatment is often far worse than the procedure itself.

Why does my tooth hurt with hot and cold drinks?

Brief sensitivity is often caused by worn enamel, exposed roots, or a small cavity. If the pain lingers for more than a few seconds after the hot or cold is gone, the nerve inside the tooth may be inflamed. A dentist can test the tooth and take an X-ray to find the cause and the right treatment.

How many visits does a root canal take?

Many root canals are completed in one or two visits. Teeth with more canals, such as molars, or teeth with an active infection may need an extra visit so the canals can be disinfected and checked before sealing. Your dentist will also plan a separate visit for a crown if the tooth needs one.

Do I need a crown after root canal treatment?

Back teeth usually need a crown after a root canal, because they take heavy chewing forces and a treated tooth can become more brittle. Front teeth with enough healthy structure may only need a filling. Your dentist will recommend the right restoration based on how much tooth remains and how you bite.

Is it better to pull the tooth instead?

Saving your natural tooth is usually the preferred option when it can be restored predictably. Keeping it helps you chew normally and prevents nearby teeth from drifting into the gap. Extraction may be sensible if the tooth is badly cracked or too damaged, and your dentist will explain the replacement options.

Can antibiotics fix an infected tooth instead of a root canal?

Antibiotics may help control spreading infection or swelling, but they cannot clean out the infected tissue inside the tooth. Without root canal treatment or extraction, the infection usually returns. Your dentist will decide whether antibiotics are needed alongside treatment, rather than as a replacement for it.
