Plaque is a soft film-like substance primarily made up of bacteria that forms on the tooth when they are not active (as in chewing). Plaque can also form just after brushing! If the plaque is not cleared for more than 72 h, it begins to harden and this hardened structure attached to the tooth is known as calculus (commonly known as tartar).10 Plaque is also identified as the initiator of caries process. Calculus on the other hand can initiate gum disorders resulting in gum inflammation and bleeding.
Formation of plaque can be controlled with effective brushing and flossing. Additionally, plaque formation can also be controlled with the use of certain medicated mouthwashes that are commonly available as over-the-counter products. Most commonly advised mouthwash contains chlorhexidine that is effective in both preventing plaque formation and reducing gum inflammation. Other medications that are included in the mouthwashes are listerine and triclosan. Control of tartar to some extent is also possible with the use of triclosan-containing mouthwashes or toothpastes.2 However, tartar or calculus once formed can be cleared only by a dentist or dental hygienist with specialized equipment.1
