The Problem: When Tooth Pain Won’t Go Away
Persistent tooth pain is more than an inconvenience—it’s usually a sign of infection inside the tooth. Many patients delay care out of fear, but modern root canal treatment is designed to
end pain, not intensify it.
You may need treatment if you’re experiencing:
- Sharp or throbbing tooth pain
- Sensitivity to hot or cold that lingers
- Swollen, tender, or sore gums
- Pain when biting or chewing
- A darkened tooth or gum pimple
If you’re searching for
root canal in Rockville MD, tooth pain relief, or emergency endodontics, these symptoms shouldn’t be ignored.
The Solution: The StarBrite Root Canal Method
At StarBrite Dental, root canal therapy is a
predictable, comfortable procedure
that removes the source of pain and restores your oral health.
Here’s how it works—simply explained:
A root canal doesn’t cause pain — it removes the source of the pain.
Root Canal = Specialty Dentistry, not Emergency Medicine
Intense toothaches, like the kind that can occur when an abscess goes untreated for too long, can be very difficult to bear. But please, don’t rush yourself to the ER if you have one. Emergency Rooms are not set up for emergency root canals and don’t tend to have staff on hand to perform them, anyway. As a matter of fact, your local emergency room will probably refer you to a practice such as StarBrite Dental.
Who Is a Candidate for Root Canal Treatment
You may be a candidate for root canal therapy if you are experiencing symptoms that suggest deep infection or severe damage inside a tooth. Common signs include lingering pain, sensitivity to hot or cold, discomfort when chewing, swelling near the tooth, or discoloration. In some cases, there may be no symptoms at all, and the issue is discovered during an exam or dental X-ray.
Root canal treatment is recommended when the pulp inside the tooth has become inflamed or infected due to decay, trauma, cracks, or a failed previous filling. If the tooth can be saved and restored, a root canal is often the best choice for long-term oral health.
You may be a good candidate if:
- You want to save your natural tooth instead of extracting it
- The tooth is structurally strong enough to support a restoration
- You have no factors preventing restorative treatment
- Your dentist determines that the infection can be fully removed
In certain cases, such as complex root systems or advanced infections, your dentist may recommend seeing a dentist that specializes in root canals.
What to Expect During Root Canal Treatment

During your root canal appointment, your dentist will begin by numbing the area to ensure you stay completely comfortable throughout the procedure. Once the tooth is numb, a small opening is made in the top of the tooth to access the infected pulp inside.
The damaged tissue is carefully removed, and the internal canals are then cleaned, disinfected, and shaped to eliminate bacteria and debris. After the canals are fully prepared, they are filled with a biocompatible material to seal them and prevent future infection.
A temporary or permanent filling is placed to close the tooth. In most cases, a dental crown is recommended afterward to protect and strengthen the treated tooth.
Most root canal treatments take about 60–90 minutes, depending on the tooth and complexity. Patients usually return to normal activities shortly after their appointment, with only mild soreness that can be managed using over-the-counter pain relief.
