Dental plaque definition prevention and removal
Dental plaque is a sticky microbial biofilm that forms on teeth and along the gumline and is removed by regular brushing and interdental cleaning.
What is dental plaque and how can you remove it?
Dental plaque is a sticky microbial biofilm that forms on teeth and along the gumline and is removed by regular brushing and interdental cleaning.
How does plaque stick to teeth and dental appliances?
Plaque contains bacteria embedded in a matrix that adheres to enamel, dentine, fillings, and appliances. Bacterial acids can contribute to tooth decay, while inflammation caused by plaque at the gum margin can develop into gingivitis and, in susceptible people, periodontitis.
How can you prevent plaque along the gumline?
Brush twice daily with fluoride toothpaste, angle the bristles toward the gumline, and clean between teeth with floss or interdental brushes. A hygienist removes calculus, which is mineralized plaque that home brushing cannot detach.
When should bleeding or rough deposits be examined?
Arrange a dental examination when gums bleed regularly, swell, recede, or teeth feel loose, or when a rough deposit remains after brushing. Toothache, sensitivity, or a persistent bad taste can signal a separate problem.
Which cleaning tools suit your teeth and gumline best?
Where is plaque accumulating, is there calculus already present, and which brush or interdental size matches my mouth?
Frequently asked questions
Can home care replace a dental examination?
Home care can reduce irritation or plaque, but it cannot diagnose the cause or treat problems that require professional cleaning, restoration, or other clinical care.
What information helps at an appointment?
Describe when the symptom began, what triggers it, any bleeding or swelling, relevant dental work, medicines, and the care you have already tried.
