How does Red Cote reveal plaque during brushing?

Red Cote is a plaque-disclosing dye used to colour dental plaque so missed areas are easier to see during brushing instruction.

Why does the dye make plaque visible on teeth?

The dye binds to bacterial biofilm on tooth surfaces and makes it visible. It is a teaching aid, not a treatment or a test for decay.

How can coloured plaque guide your cleaning routine?

A dental professional may apply it, ask you to rinse, and demonstrate brushing and interdental cleaning on the coloured areas. Follow instructions for rinsing afterward.

When do plaque and gum symptoms need dental assessment?

Ask for assessment if plaque is accompanied by bleeding, swelling, bad breath, pain, or loose teeth.

What should you ask about the areas highlighted by dye?

Ask which surfaces were missed, which cleaning tool reaches them, and when plaque control should be reviewed.

Frequently asked questions

Can a red plaque-disclosing dye have more than one cause?

Yes. Examination helps distinguish the tooth, gum, restoration, or surrounding tissue involved.

What may the dentist do?

The dentist may inspect the mouth, test teeth and gums, and use imaging when the findings require it.
