Root Canal Therapy

In Australia thousands of Root Canals are done each day, with the aim of saving dead teeth. However what is not so well known is that some holistic health practitioners believe keeping these dead teeth in the body may not be healthy/the healthiest choice.

Dental abscess

Often the problem starts with an infection in the mouth called a dental abscess. These are caused by bacteria, usually from decay in a tooth which has been left untreated. These infections can extend into the gums, cheek and sometimes even into the jaw bones. An abscess triggers pain when the tissue becomes inflamed due to the pressure building within the infection. Pus may collect at the site of the infection, causing swelling and sometimes a foul taste and odour is noticed. The condition can become progressively more painful and serious even causing nausea, vomiting, fever and chills. Pressure in the neck and on the windpipe can cause difficulty breathing, so it’s important to get treatment early.


Even though the pain may subside, the tooth should not be left infected in the body as it is unhealthy. There are two options available, extraction of the tooth, or Root Canal Treatment. With an extraction, the tooth is lost forever, and in many cases this can affect how well a patient can chew healthier foods such as raw vegetables and nuts. It can also affect a person’s appearance if the hole left behind is visible in their smile, which can have a negative effect on their confidence and self-esteem.

The case for and against root canals.

If a root canal treatment is well done, and that means the entire length of the tooth canal is thoroughly cleaned and dressed with antiseptic and then it is correctly sealed, then most times the infection or abscess around the tooth will heal. This can be easily seen on an X-ray, where at the beginning there is a shadow around the tooth root in the bone showing bone loss and 12 months later after a good root canal treatment has been done, we see healing. This shows the bone is filling in again, so there is a strong sign of healing and that something very positive has happened. In a healthy individual with a healthy immune system, a well done root canal treatment could last a long time.

The case against is that no matter how well the root canal treatment is done, because of the natural structure of the tooth, which contains many, many extra canals and millions of little tubules or tunnels in the tooth wall none of which can be sterilised and filled, then a tooth will never be completely sterilised or infection-free. Because of this toxins are constantly being released into the body and challenging the immune system and this is why some say it is best to remove a dead tooth or a tooth with a root canal treatment.

The problem with removing the dead tooth or the tooth with the root canal treatment of course is what do we do to replace it? Sometimes people go without a tooth, but if it’s one they need to chew, or if they are left with a dark hole in their smile, it can be important to replace it. There are three choices to replace a missing tooth.

The first is a denture. A denture is loose, it’s not fixed in and it’s usually not as solid to chew on. Dentures need to be removed after every meal to be cleaned and even with good cleaning there is potential for gum inflammation. The second option is a bridge which involves placing a crown on the tooth either side of the gap, with an attached false tooth in the middle. This is stuck on and doesn’t come out, but it affects teeth on either side of the gap. And the third option is an implant which has a false tooth root implanted into the jaw bone. Each of these treatment options leads to more complex treatment, so in our practice we consider each case individually based on many factors including the person’s overall health and immune system.

Root Canal Treatment FAQs

In the past, you would most likely lose a tooth if it had a diseased or injured nerve. Thanks to root canal therapy, however, extraction is no longer required. As dental healthcare professionals, our job is to save your natural tooth wherever possible, and the root canal treatment is able to do just that.

Root canal is unfortunately one of the most misunderstood treatments out there, no thanks to the distorted perception of it being a painful procedure. Quite the opposite, the therapy is designed to offer pain relief while curing the root cause of the infection that has affected the pulp tissue of the tooth.
