The Truth Behind Root Canals San Jose, CA
Root canals are one of the most common dental procedures. A root canal treatment is when the dentist removes inflamed or infected pulp from the tooth center, cleans and disinfects the remaining space, and then fills and seals it. This procedure eliminates bacteria from the affected area, prevents reinfection, and preserves your natural tooth.
Root canals are available at NuSmile Dental & Orthodontics and the surrounding area. Chances are you have heard a lot of misconceptions about the procedure. Our staff can provide the truth behind root canals—call 408-791-2800 to schedule a consultation.
When a Root Canal Is Needed
Root canals are a fairly straightforward procedure that repair and protect badly decayed or infected teeth. The pulp of the tooth, which contains the nerves and blood vessels, can become irritated and infected for many reasons. These include deep decay, repeated dental procedures, large fillings, a chip or crack, or facial trauma.
Some of the symptoms that indicate a need for a root canal include:
- Sensitivity to hot or cold foods and liquids
- Severe discomfort while chewing or biting
- Small, pimple-like irritations on the gums
- Swollen or tender gums
Patients who are experiencing any of these symptoms will want to make an appointment to see our dentist. The more time goes by, the more likely the tissue surrounding the tooth will get infected — increasing the chances that the tooth may have to get extracted. However, there is no need to worry. Getting a root canal is no worse than getting a filling and is effective.

Root Canals & Safety
Root canal treatments save millions of teeth each year. The American Association of Endodontists (AAE) estimates that over 15 million of these procedures are performed in the United States every year. On average, this comes out to over 41,000 root canal treatments per day.
This common procedure is both safe and effective, leading to predictable results. In fact, it is usually more dangerous to leave a tooth untreated than it is to undergo a root canal treatment. Root canal treatments are only necessary once bacteria have begun to multiply inside the tooth, causing an infection or abscess. This may lead to bone loss around the tip of the tooth's root; drainage problems extending from the root; and swelling in other areas of the face, head, or neck. Root canal treatments can stop these effects.

Common Myths About Root Canals
Unfortunately, there are many common myths about root canals that stop patients from seeing the endodontist. The main three misconceptions are:
- It is painful to get a root canal.
- Getting a root canal will cause illness.
- Tooth extraction is better than root canal treatment.
While root canal treatment may have been painful in the past, modern technology and anesthetics have made the experience no more discomforting than getting a cavity filled. Root canal treatments also reverse toothaches by removing the source of infection or inflammation. Plus, endodontists are experts in pain management.
Furthermore, the claim that links root canal treatment to illness is based on an outdated and poorly designed research study that has long since been debunked. While some may claim that root canal treatment may make patients more likely to become ill or contract certain diseases in the future, there is no valid, scientific evidence supporting this theory.
Finally, it is always best to save a natural tooth whenever possible. In most cases, this is safer, less painful, and more economical than a tooth extraction. Preserving a natural tooth lessens the risk of further infections, and, as mentioned, root canal treatments are typically not as painful as people believe. Many people also mistakenly believe that tooth extraction is the cheaper option. However, this is often untrue when considering the whole picture.

Rare Complications
While rare, some complications may present themselves after a root canal procedure. If the pain goes away but then returns, patients will want to schedule an exam. A new infection can take hold if a canal got missed in the roots, a crack in the tooth root went undetected, or sealing material broke down over time. Other complications include teeth breaking if a crown was not placed in a timely fashion, root fracture from decay, or numbness from the material used to fill the root canal leaking into other areas of the tooth.
Sometimes, another root canal can fix the problem or need a root-end resection procedure. Always remember to follow all of the post-procedure instructions provided by our dentist to heal quickly. Patients who start experiencing any complications should call our office to schedule an appointment.

Pros and Cons of Root Canals
Many of the advantages of undergoing root canal treatment are apparent. These include pain relief, stopping the spread of infection, curing dental decay, and preventing further damage to the tooth pulp. By preserving the tooth, root canal treatments prevent unnecessary tooth extraction and balance the patient's bite. They also protect the surrounding teeth from infection and strain. When properly cared for, root canal treatment results can last for a lifetime.
However, there are some possible disadvantages as well. Still, these are typically necessary trade-offs. For example, the treated tooth may not be as strong after the procedure. The doctor can address this by capping the tooth with a crown for added protection. Patients may also be at risk for discomfort, toothache, or reinfection. The doctor may also miss any hidden roots or canals, necessitating retreatment in the future. Choosing the right endodontist and following all the doctor's instructions can help minimize the chances of any complications.
