Few dental procedures spark as much unnecessary fear as root canals, largely due to outdated information and persistent myths passed down through generations. The phrase “I’d rather have a root canal” has become synonymous with something unpleasant, yet the reality is far different from this reputation. Modern root canal therapy is a routine procedure designed to save your natural tooth, relieve pain, and prevent more serious health complications, all while keeping you comfortable throughout the process.

Understanding what actually happens during a root canal can ease your concerns and help you make informed decisions about your dental care. At DG Dental, we use advanced techniques and technology to perform root canal treatments and other restorative procedures with precision and minimal discomfort. Dr. Dory Green’s extensive training in endodontics, combined with her commitment to patient comfort, means you’ll receive care in our spa-like environment where anxiety melts away.

Debunking Common Root Canal Myths

The biggest myth surrounding root canals is that they’re extremely painful. In reality, the infection causing your toothache is what hurts, not the procedure itself. Modern anesthetics completely numb the area, and most patients report feeling no more discomfort than they would during a standard filling. Many people actually feel immediate relief once the infected tissue is removed and the pressure inside the tooth is released.

Another common misconception claims root canals cause illness or weaken your immune system. This myth originated from research conducted nearly a century ago that has been thoroughly debunked by modern science. Root canal therapy actually removes infection from your body, improving rather than harming your overall health. Some people believe extracting the tooth is a better option, but saving your natural tooth is almost always preferable. Extraction leads to bone loss, shifting teeth, and the need for more expensive replacements like implants or bridges.

What Actually Happens During the Procedure

A root canal becomes necessary when the soft tissue inside your tooth, called the pulp, becomes infected or inflamed. This can happen due to deep decay, repeated dental procedures on the same tooth, a crack or chip, or trauma to the tooth. The pulp contains nerves and blood vessels, and when it becomes infected, bacteria multiply inside the tooth, causing pain, swelling, and potentially an abscess.

During the procedure, we create a small opening in the top of your tooth to access the infected pulp chamber. Using specialized instruments and digital imaging for precision, we carefully remove the infected tissue, clean and disinfect the inside of the tooth, and shape the canals. We then fill the empty space with a biocompatible material called gutta-percha and seal the tooth to prevent future infection. The entire process typically takes 1-2 appointments depending on the complexity of your case.

Advanced Technology for Better Outcomes

We use digital x-rays and advanced imaging to see exactly what we’re treating, ensuring we don’t miss any infected tissue or hidden canals. Rotary instruments allow us to clean and shape your tooth’s interior more efficiently and comfortably than traditional hand files. This technology reduces treatment time and improves success rates. We also offer sedation options for patients who feel anxious, though most people find the procedure much easier than they anticipated once they experience it firsthand.

Recovery and Long-Term Results

After your root canal, you might experience some mild tenderness for a few days as your body heals. Over-the-counter pain relievers typically manage any discomfort effectively. Most patients return to work or their normal activities the same day or the next day. Avoid chewing on the treated tooth until we place your permanent restoration, as the tooth is more fragile without its final crown.

Your treated tooth will usually need a crown to protect it and restore full function. We use digital scanning technology (rather than messy impressions) to create your custom crown, which fits precisely and looks completely natural. With proper care, including regular brushing, flossing, and dental checkups, a tooth that’s had a root canal can last a lifetime. Success rates exceed 95%, making root canal therapy one of the most predictable procedures in dentistry.

The alternative to a root canal is extraction, which creates additional challenges you should consider:

  • You’ll need an implant, bridge, or partial denture to replace the missing tooth
  • Adjacent teeth may shift into the empty space, affecting your bite
  • Bone loss occurs in the jaw where the tooth was removed
  • Replacement options cost significantly more than saving your natural tooth

Even with these replacement options available, keeping your natural tooth through root canal therapy offers the best long-term outcome for your oral health and your budget.

Root canals don’t deserve their fearsome reputation. Modern techniques, advanced technology, and effective anesthesia have transformed this procedure into a routine treatment that saves teeth and relieves pain rather than causing it.
