In Dental Clinic Acedo, We truly care about the oral health of our patients. Therefore, we want to dedicate this blog to a topic of great importance: dental biofilm, also known as bacterial plaque.

He dental biofilm It is a complex community of microorganisms That adhere to the surface of the teeth and gums, forming a movie sticky. If not removed regularly, it can lead to serious oral problems such as cavities, gingivitis and periodontitis.

In this blog, we will cover in depth everything you need to know about dental biofilm: what it is, how it forms, how to remove it, and how to control it to maintain a healthy smile.

He oral biofilm It is a biofilm composed of bacteria, fungus and other microorganisms that adhere to the hard surfaces of the mouth, such as teeth, gums, and dentures. This biofilm is made up of an extracellular matrix that protects the bacteria and allows them to communicate with each other.

He oral biofilm it's a phenomenon natural and it is not harmful in itself. However, if not removed on a regular basis, it can accumulate and harden, becoming tartar. Tartar irritates the gums and creates a favorable environment for the growth of pathogenic bacteria, which can lead to oral diseases.

The training of oral biofilm is a gradual process which occurs in several stages:

  1. Accession: Bacteria adhere to the surface of teeth and gums using proteins called fimbriae.
  2. Colonization: Bacteria multiply and form colonies.
  3. Maturation: The biofilm becomes more complex and resistant.
  4. Mineralization: The biofilm calcifies and turns into tartar.

There are various factors that can promote the formation of dental biofilm, as:

Removing this is essential to maintaining good oral health. There are two main methods to remove it:

1. Oral hygiene:

2. Professional dental cleaning:

It is recommended to visit the dentist at least once a year for a dental cleaning professional. In this cleaning, the dentist will remove tartar and biofilm from areas that are difficult to clean with brushing and flossing.

In addition to removing dental biofilm on a regular basis, there are other measures you can take to control it:

Stages of dental biofilm formation

Dental biofilm forms through a progressive process that begins a few minutes after brushing. In the first phase, the acquired pellicle is created—an invisible layer of salivary proteins that adheres to the enamel. Next, the initial bacteria attach to this surface and begin to multiply. In the maturation phase, the bacteria produce a protective matrix that allows them to organize themselves and resist mechanical removal. Finally, the biofilm becomes more complex and pathogenic, promoting the development of cavities and gum disease if it is not properly removed through oral hygiene and professional checkups.

Smiles that draw health and well-being!
