What does “Dental plaque” mean?
Dental plaque is a biofilm of bacteria and their products attached to tooth and other surfaces. Unlike food debris, it grows attached to a surface and is a key target in managing decay and gum inflammation.
Original spelling: 플라크
It accumulates even when difficult to see
Plaque tends to remain in hard-to-clean areas such as gumlines, between teeth, and around prostheses. Acid production from sugars contributes to demineralization, and buildup around gums is associated with inflammation. Rinsing with water alone does not remove all attached plaque.
How it differs from tartar
Tartar is a hard deposit formed when plaque combines with minerals. Soft plaque can be reduced through brushing and interdental care, while hardened tartar needs professional removal. The degree of visible staining alone does not indicate plaque quantity or gum health.
Why repeated care is needed
Plaque reforms after removal, so one professional cleaning does not complete care. Brush tooth surfaces with fluoride toothpaste and use suitable interdental tools between teeth. Plaque-disclosing agents can help identify missed areas but do not replace diagnosis or treatment.
Frequently Asked Questions
Are plaque and food debris the same?
No. Plaque is a biofilm attached to the tooth surface; food debris is trapped or remaining food. Plaque can remain even if the mouth looks clean after rinsing.
Can mouthwash alone remove plaque?
Mouthrinses may serve as adjuncts according to their purpose, but do not replace brushing and mechanical cleaning between teeth.
