The calculus on your teeth is mainly composed of bacteria. Before and after scaling, clean teeth are healthy when they are dry! Why do we need to clean our teeth? The same as why we need to brush our teeth? It is the same reason. To freshen your breath? To remove food residue? All of these are true, but not the main thing. In fact, the main purpose of brushing our teeth is to remove and interfere with the formation of plaque. So what is plaque? Plaque is the group of microorganisms that adheres to the surface of the teeth or other soft tissues in the mouth. It is formed by the reaction of remaining food residues in the mouth with bacteria and is invisible to the naked eye. Plaque is the culprit of tooth decay, dental calculus, gingivitis and periodontitis. In addition, plaque is adhered to the tooth surface and is very cunning and cannot be washed away by water or rinsed off. Even if we brush our teeth hard, there are still some stubborn elements hiding in the hidden corners to grow and develop. If we are not careful, the plaque will further calcify and become calculus. More calculus will lead to inflammation of gums, bleeding gum recession and loosening of teeth! Scaling can be a good way to prevent and treat periodontal disease. Residue that stays on the teeth for a long time can affect the dental health and cause periodontal disease, and scaling can remove just that.
