Know the Warning Signs
Do You Need a Root Canal?
Tooth pain is your body sending an urgent message. Delaying treatment risks losing the tooth entirely. If you experience any of the following, call our Richardson office the same day.
Severe Toothache
Intense, throbbing pain that doesn't let up — especially when biting or applying pressure — signals deep infection inside the tooth.
Prolonged Sensitivity
Sensitivity to hot or cold that lingers for 30+ seconds after the stimulus is removed points to damaged or infected nerve tissue.
Darkened Tooth
A tooth that has visibly darkened or changed color suggests the inner pulp is dying — a sign that needs prompt attention.
Swollen or Tender Gums
Swelling, tenderness, or a small raised pimple on the gums near the painful tooth often indicates an abscess requiring immediate care.
Chipped or Cracked Tooth
A chip or crack exposes the inner pulp to bacteria. Even if there's no pain yet, infection can develop rapidly and spread.
Loose Adult Tooth
An infected tooth can soften the surrounding bone, causing adult teeth to feel loose. This is an emergency that needs same-day evaluation.
What to Expect
The Root Canal Process at Smiles of North Dallas
Root canal therapy — technically called endodontic treatment — removes infected or inflamed pulp tissue from inside the tooth, cleans the canals, and seals them to prevent reinfection. The procedure saves the tooth entirely, avoiding extraction.
With Dr. Thaher's gentle injection technique and modern rotary instruments, most patients experience minimal discomfort. Many compare it to getting a routine filling.
⚠ The Myth Worth Killing
"Root canals are painful." This fear is decades out of date. The procedure eliminates the pain caused by infection — it doesn't create it. The infection itself is the source of suffering, and root canal therapy ends it.
Diagnosis & X-Ray
1
Digital X-rays confirm infection depth and identify the number of canals. We explain exactly what we find before anything begins.
Anesthesia
2
Dr. Thaher applies topical numbing gel before the injection, then uses a slow, gentle technique that most patients barely feel.
Pulp Removal
3
We combine a thoughtful, human-centered approach with clear communication and reliable results. It’s not just what we do—it’s how we do it that sets us apart. A small access point is created. Infected pulp is carefully removed with precision rotary instruments while you remain completely numb.
Cleaning & Shaping
4
Canals are cleaned, shaped, and disinfected with antimicrobial solutions to eliminate all bacteria.
Sealing
5
Canals are filled with a biocompatible material called gutta-percha and sealed. A temporary or permanent crown is then placed to restore the tooth.

Root Canal FAQs
Still have questions? Call us at (972) 644-9595 - our team is here to put your mind at ease before you ever sit in the chair.
-
Modern root canals are no more uncomfortable than getting a filling. Dr. Thaher applies topical gel before numbing the area and uses a slow, controlled injection method that virtually eliminates the sting. Most patients are genuinely surprised by how comfortable the entire experience is.
-
Most root canals are completed in one appointment lasting 60–90 minutes. More complex cases involving multiple canals or severe infection may require a second visit. We will give you a clear timeline before starting any treatment.
-
Common warning signs include severe or throbbing toothache, sensitivity that lingers after exposure to hot or cold, a darkened tooth, swollen or tender gums, and a pimple-like bump on the gums near the problem tooth. If you notice any of these, call us at (972) 644-9595 immediately — waiting makes infection worse and can cost you the tooth.
-
Cost depends on which tooth is being treated (front teeth are simpler than molars) and your insurance coverage. We provide a full cost estimate before starting. Uninsured patients can enroll in our in-house QDP plan, and we offer low monthly financing through Cherry and CareCredit.
-
If local anesthesia only was used, yes — you can drive yourself home. If you chose sedation dentistry for your comfort, you will need someone to drive you. We offer sedation options for patients with dental anxiety; let us know when you book.
-
Yes — once your permanent crown or bridge is cemented, you can eat normally. While wearing the temporary, avoid hard, sticky, or chewy foods. After your final placement, we recommend avoiding habits like chewing ice or biting nails that can shorten any restoration's lifespan. -
A filling repairs a small portion of a tooth. A crown covers the entire tooth. When decay or damage is too extensive for a filling to reliably hold — or when the tooth is at risk of cracking further — a crown is the stronger, longer-lasting option.
