Many adults and children suffer from tooth decay and cavities. No matter what some people do they still battle with these issues and need some extra help to maintain good oral health.

What Causes Tooth Decay?

There are several types of bacteria that live in your mouth. Some of them are good and others are bad and can cause tooth decay.

Streptococcus mutans, which is also known as “S. mutans”, is a type of bacteria that is regarded as the the main contributor to decay and the breaking down of your tooth enamel. Streptococcus mutans is found on most tooth surfaces and this is especially true in the hard to reach areas.

The bad bacteria, like Streptococcus mutans, interact with the food and drink in your diet to form an acid that breaks down your tooth enamel. Eating foods that are high in sugars and complex carbohydrates will help fuel this process.

The Colgate Oral Care Center reports that the following will help most people combat tooth decay and cavities:

  • Avoiding food and drinks that are high in sugar
  • Brush your teeth twice a day
  • Have regular dental checkups and cleanings
  • Floss every day (remembering that bacteria can thrive in those hard to reach areas that your toothbrush cannot reach)

As stated previously, remembering to consistently do these things will be successful for most people, but what can be done it these things aren’t enough for you?

Chlorhexidine Gluconate Rinse

As stated above chlorhexidine gluconate is typically prescribed by a dentist.

Research Comparing Coconut Oil and Chlorhexidine on Streptococcus Mutans

In 2016 results of a research study that compared the effects of coconut oil and chlorhexidine on Streptococcus mutans was published in the Journal of International Society of Preventive & Community Dentistry.

The study consisted of two groups of female children between the ages of 8 and 12. One group was asked to perform oil swishing (oil pulling) with coconut oil for 2-3 minutes after brushing. The other group used chlorhexidine rinse instead. Then the amount of S. mutans in plaque and saliva was measured for the participants in each group on day 1, day 15, and day 30.

The results of the study found that there is a statistically significant decrease in S. mutans. count from coconut oil as well as chlorhexidine group from baseline to 30 days.

This means that coconut oil pulling is as effective as chlorhexidine rinse in the reduction of S. mutans.
