If there is one thing that patients and dentists agree on whole-heartedly, it’s how much both would like to see cavities become a thing of the past. Currently, the most effective tool against dental decay is a consistent and thorough dental hygiene routine. Even brushing twice each day, flossing, and using mouthwash can’t eliminate the risk of cavities completely. Recent research conducted by a team of dental specialists led by Dr. Russel Pesavento has revealed what may spell the end of cavities forever.
Over 90% Of All Adults Over 20 Have Experienced Cavities Since Childhood
How Cavities Develop
The first step to developing a tool that can end cavities forever is understanding the underlying cause of cavities. For years we’ve been told to stay away from sugary snacks and acidic drinks, all without being told that’s not the actual cause. Instead, it is the bacteria that feed on these sugary snacks and take advantage of weaknesses in our enamel caused by the acid produced by them. Regular brushing helps to combat the formation of plaque by these bacteria and thus reduce the likelihood of developing a cavity. Cavities go through multiple stages in their development, including:
White spot lesion formation on the surface of the tooth
Destruction of enamel leading to these spots deepening in color
Underlying dentin being impacted by decay due to the absence of protective enamel. Pain is common at this stage
Infection of the pulp by bacteria that have penetrated both layers, often resulting in root canal treatment.
Formation of abscesses that can lead to the destruction of bone, tooth, and tissue.
All of these stages result from the same factor, the growth of bacteria and plaque in the oral cavity. If not properly addressed, the affected teeth may have to be extracted, and damage to the jawbone may occur. Death can sometimes result if the infection spreads into the patient’s bloodstream.
Over 700 Species Of Bacteria Are Present In Our Mouth, Not All Of Them Are Harmful
How The Complex Ecosystem Of Our Mouth Complicates Cavity Prevention
Understanding that the bacteria in our mouths are responsible for tooth decay, it would be understandable to ask why we don’t just eliminate the bacteria. The problem lay in that of all the hundreds of species in our mouths, many of them are important to maintaining our dental and overall health. Without tools for specifically eliminating the harmful bacteria, we could end up doing more harm than good.
Research has uncovered an approach to this concern that may solve all the extant questions. ‘Cerium oxide nanoparticle solution’ is the name of a discovery that may change the very face of cavity prevention. The bacteria that create plaque, also known as biofilm, has been shown to be reduced by as much as 40% in the presence of this material. While a far cry from the total elimination of decay, it represents a significant step forward in dentistry’s battle against cavities.
