BEST ORAL HYGIENE SPECIALIST IN ARUMBAKKAM! Plaque is a clear sticky residue that is constantly forming on your teeth throughout the day and night. Plaque begins to develop on our teeth within hours after eating. Food particles, bacteria and saliva all combine to form this colorless film. It’s what makes your teeth feel “dirty” between brushings or upon waking in the morning. The bacteria in your mouth are having a field day. The result is a variety of acids, which attack your teeth and gums. This is the same bacteria, which if left unchecked, produce gingivitis and cavities. The key purpose of brushing and flossing is to consistently interrupt this bacterial growth. If it isn’t, it can harden into tartar.
