Plaque staining tablets
Plaque-disclosing tablets color the bacterial biofilm left on teeth so you can see where brushing and cleaning between teeth need improvement.
The short answer
Plaque-disclosing tablets contain a dye that binds to dental plaque, the sticky biofilm on tooth surfaces, and temporarily colors it. They reveal missed areas but do not remove plaque or replace brushing and interdental cleaning.
What does the colour from a plaque tablet represent?
The colored film is plaque mixed with saliva and bacterial products, not a permanent stain in enamel. The shade may also mark food debris or an uneven surface, so the result is a visual guide rather than a diagnosis of gum disease or tooth decay.
How should you use plaque-staining tablets at home?
Brush and clean between teeth first, then use the tablet exactly as its label directs and inspect the gumline, grooves, and spaces between teeth in a mirror. Spit and rinse as directed, then brush away the remaining dye; protect clothing and follow any age or allergy warnings on the product.
When do bleeding or swollen gums need examination?
Ask for an examination if gums bleed repeatedly, look swollen, or pull away from teeth, or if a rough deposit remains after brushing. A dental professional can remove hardened calculus, which a tablet cannot dissolve.
What should you ask about your plaque-control technique?
Ask where plaque is collecting and whether the technique or brush needs changing. Ask whether the colored material is soft plaque or hardened calculus and whether a professional cleaning or gum assessment is needed.
Frequently asked questions
Will the tablets stain my teeth permanently?
The dye is intended to be temporary, but follow the product instructions and ask a dentist or pharmacist about a persistent color change.
Can tablets show cavities?
No. They can show plaque locations, but a cavity requires a clinical examination and sometimes dental imaging.
Should children use them?
Use an age-appropriate product with adult supervision and follow its label directions.
