Dental biofilm
Pathologies Dental biofilm Research over the years has shown that many microbial species, especially those of the microorganisms that have been Bacteria tend to organize themselves in the form of biofilms to increase their resistance to antibacterial agents. and thus ensure their survival.  Dental biofilm plays a key role as a precursor to two major oral diseases. Understanding their structure and biology is fundamental to understanding the etiopathogenic processes underlying dental caries and periodontal disease. 

Where does the biofilm form?

The formation of these biofilms is possible in many areas of the body and, when it occurs, it is capable of favor the emergence and growth of different microorganisms, especially bacterial colonies that can cause an infection. Biofilm, also known as biofilm or biofilm or microfoulingrepresents a a kind of protective shield for microorganisms.  

How is it produced?

Even in good health, it is normal to find a diversity of microorganisms in the mouth. These can be in free form, moving independently, or deposited on the different oral structures, where it is common to find them in the form of colonies.  The process of dental biofilm formation, therefore, begins spontaneously.  The stages of dental biofilm formation are: 
  • AdhesionAdhesion: microorganisms reach a surface and bind to it thanks to the acquired or salivary film. This glycoprotein film covers all the oral structures and moisturizes and protects the tissues., but it also serves as a substrate for the attachment of microorganisms.
  • ColonizationOrganization of microorganisms according to their species in colonies. Formation of the biofilm by generation of a matrix of extracellular substances that they themselves produce.
  • Growthincrease in number and species of microorganisms in the biofilm. In order to survive, the colonies organize themselves to allow the passage of water and nutrients.
  • DispersionOnce the structure is well established and organized, parts of the biofilm become detached and adhere to other surfaces.
The species of microorganism that gives rise to dental biofilm and the type of surface to which it adheres. determine the pathogenicity, rapidity and degree of resistance of the biofilm to antimicrobial agents. 

Dental biofilm or bacterial plaque: prevention, consequences and treatment

Also known as dental patina and, more commonly, as bacterial plaque, the biofilm dental has the same characteristics as microbial biofilms that form elsewhere in the body, where they are capable of causing specific and very serious diseases.. For this reason, it is important to prevent the formation of dental biofilm or to intervene professionally to remove it. [card-product id="22745"]


Our mouth is an environment rich in microorganisms, including bacterial ones, which tend to organize themselves into colonies to ensure better survival. Dental plaque is one of the most common examples of biofilms.In fact, their formation follows the process of microbial biofilm creation that takes place in other parts of the body: 
  1. Hydrophobic substances and macromolecules are attracted to and adhere to teeth or dentures.. In this first phase, the film, consisting of proteins and salivary substances, is thin and therefore easy to remove by brushing, as it is still free of bacteria.
  2. The free energy of the surface of this biofilm and the electrical charge of the surface of teeth and dentures undergo changes that favor bacterial adhesion. undergo changes that favor bacterial adhesion.
  3. Bacteria that are well adhered increase their metabolic activity, producing more toxins that will eventually damage oral health.
  4. Bacteria reproducethus increasing the size and resistance of the biofilm.
  5. Bacteria from the deep layers, well protected by the upper layers, attack periodontal tissues, attack the periodontal tissues.
Dental biofilm is not always clearly visible to the naked eye; tends to form mainly in the interdental spaces and near the gingivaethat is to say, in the most difficult spaces to clean. The extent of the damage it can cause is not obvious at first glance, but, as we will see, the pathologies associated with it are very important. 

Dental biofilm formation: prevention and consequences

Unfortunately, the process of dental biofilm formation is very fast. and, if not interrupted at an early stage by maintaining proper oral and professional hygiene, soon becomes responsible for the most common oral diseases.. Brushing teeth properly, with the right toothbrush and toothpaste and with the right frequency, flossing and, if necessary, using the right mouthwashes.The only preventive tools that can counteract the formation of dental biofilm, which is always lurking, along with the correct frequency of professional oral hygiene reminders, are the only preventive tools that can counteract the formation of dental biofilm.  Understanding the importance of these actions is not difficult, if you think that plaque is the main responsible for the chronic infections that lead to three of the most important dental diseases: 
  • Cariesif the biofilm includes bacteria capable of converting sugars into acids, tooth enamel is eroded, leading to caries.
  • GingivitisGingivitis is another chronic infection caused by bacteria capable of attacking the tissues that support the tooth.
  • PeriodontitisPeriodontitis: is the evolution of untreated gingivitis, which can be resolved and kept under constant control. The evolution of this pathology, however, is based on plaque and its consequences can also include, in extreme cases, the loss of the affected tooth.
