Standard Root Canal Treatment vs. the GentleWave Procedure

If you’ve been told that you need a root canal, it means that the pulp-filled cavity of your tooth has become infected or inflamed.

Where is the Pulp of the Tooth?

A healthy tooth is made up of enamel (the outside layer), dentin (a hard tissue) and the pulp (a soft tissue that contains the tooth’s nerves and blood vessels). The pulp of the tooth extends from the crown, which is the portion of the tooth that you see, all the way through the roots of the tooth. If the pulp of a tooth becomes infected or inflamed, root canal therapy is required to remove it and relieve the symptoms associated with the infection.

GentleWave ProcedureWhat Causes Pulp Inflammation?

The pulp of the tooth may become inflamed for a variety of reasons, including:*

  • Decay deep within the tooth
  • Repeated dental procedures on the tooth
  • Injury to the tooth
  • Crack or chip in the tooth

How Do I Know if I Need a Root Canal?

If you have an infected root canal system, there are various signs and symptoms you may be experiencing, including:**

  • Constant toothache
  • Lingering sensitivity
  • Discharge or drainage from the tooth
  • Tooth discoloration (greyish-black)
  • Toothache in the bone
  • Toothache while chewing
  • Swollen gums


Treating an Infected Root Canal

Just as there is more than one reason a root canal system may become infected, there is more than one type of root canal therapy. While certain methods have been around much longer, and therefore are more common, patients have the option of choosing the method that best suits their needs.

Standard Endodontic Treatment

Standard root canal treatment (RCT) is the type of root canal therapy that has been around the longest. In fact, the roots of standard RCT go back to 1838,* when the first root canal instrument was constructed from a watch spring.

During standard root canal treatment, files and treatment fluids are used to remove the infected pulp tissue and clean and disinfect the root canal system.

Before treatment, patients can expect to receive either local anesthesia or a numbing agent to reduce discomfort. During treatment, fluid is placed through the root canals and files are used to remove the infected pulp tissue. After the root canal system is cleaned and shaped, the canals are filled and sealed, and a temporary filling is placed to close the opening. The final step of standard root canal treatment is the placement of a filling or crown, which typically occurs at a second appointment.

But, since the root canal system is very complex and consists of several twists and turns, standard RCT can leave behind infected tissue.2 It can be difficult for the files used in standard RCT to reach through the entire canal system, including the microscopic crevices of the canal wall.

GentleWave ProcedureThe Minimally Invasive GentleWave® Procedure 

The GentleWave Procedure is an alternative to standard root canal treatment. This minimally invasive1 alternative utilizes fluid dynamics and broad spectrum acoustic energy to clean and disinfect the root canal system.

The GentleWave Procedure has been described as more comfortable than standard root canal treatment.4 While it is minimally invasive,1 the procedure fluids are still able to reach through the entire root canal,1 including the microscopic spaces that standard root canal treatments cannot.3 And since the GentleWave Procedure cleans the deepest, most complex portions of the root canal system,1,2 there’s less chance of failure over time!4 In addition, this fast-healing4 root canal procedure can be completed in just one session,4 while standard RCT often requires two appointments.

Choosing a Method of Root Canal Therapy

If you’ve been diagnosed with a root canal system infection, there are two things to consider—the type of root canal provider who will perform your root canal procedure, and the type of root canal therapy method you’ll receive.

Both dentists and endodontists perform root canal therapy, allowing you to seek treatment from either your dentist or be referred to an endodontist. But, as you look into your provider options, it’s important to consider whether you want standard root canal treatment, or the GentleWave Procedure.

The GentleWave Procedure is the minimally invasive1 root canal alternative. Individuals who choose the GentleWave alternative enjoy:

  • Less time with their dentist or endodontist4
  • Less chance of failure over time4
  • Less discomfort than standard RCT4

The GentleWave® Procedure is a medical procedure that is designed to prepare, clean and preserve the structure of teeth1,2,4 indicated for root canal therapy. Comparable to similar treatment options, there is a potential risk of adverse effects. If you are considering the GentleWave Procedure, ask your clinician if you are a proper candidate.
