Butler red cote disclosing tablets
Plaque-disclosing tablets stain bacterial plaque so you can see missed areas and improve brushing and interdental cleaning.
The short answer
Plaque-disclosing tablets use a food-grade dye to stain dental plaque, helping you see where brushing and interdental cleaning have missed bacterial deposits. Red or pink areas usually mark plaque that remains on enamel, along the gumline, or between teeth.
What happens when a disclosing tablet is used?
A disclosing tablet is chewed briefly and spread over the tooth surfaces with the tongue, then the mouth is rinsed lightly. The colour is a visual indicator of plaque, not a diagnosis of decay, gum disease, or enamel damage.
How can you use the colour to improve cleaning?
Follow the product directions, inspect the gumline, molars, and spaces between teeth in a mirror, and brush the coloured areas with a soft-bristled brush. Clean between the teeth with floss or an interdental brush, then rinse and repeat occasionally to check your technique.
When do stained areas need a dental examination?
Arrange an examination if staining repeatedly appears with bleeding, swelling, persistent bad breath, loose teeth, or pain. A dentist or hygienist can remove hardened calculus and check whether plaque has contributed to gingivitis or periodontitis.
What should you ask about missed plaque areas?
Ask which sites are being missed, whether the dye is appropriate for your mouth, and which interdental size fits each space. Ask whether professional cleaning or a gum assessment is needed if coloured deposits remain after careful home care.
Frequently asked questions
Will the colour stay on my teeth?
It usually fades with brushing and saliva, but the dye may temporarily colour the tongue or lips.
Can tablets replace dental cleaning?
No. They reveal plaque, while a professional removes calculus that a toothbrush cannot detach.
