Red cote tablets
Red Cote disclosing tablets stain plaque so missed brushing areas are visible; they do not remove plaque or treat disease.
The short answer
Red Cote tablets are disclosing tablets used to reveal dental plaque by staining it a visible colour after the tablet is chewed and spread over the teeth. They help show missed areas, but they do not remove plaque or treat gum disease.

Why does the tablet dye show plaque near the gums?
The dye binds to the soft plaque film on tooth surfaces, making it easier to see around the gum line, between teeth, and near orthodontic appliances. A stained area is a cleaning guide, not proof of a cavity or a diagnosis.
What should you do after using a plaque-disclosing tablet?
Follow the product instructions, spit out the dye, and brush and clean between teeth afterward. Protect clothing and check the label for ingredients if you have allergies or an unusual reaction; ask a dental professional how to interpret persistent stained areas.
When should stained plaque areas be checked by a dentist?
See a dentist or hygienist if staining repeatedly highlights bleeding gum margins, heavy deposits, bad breath, pain, or loose teeth. Swelling with fever or spreading facial swelling needs urgent care.
Can plaque-disclosing tablets show whether you have cavities?
Can the tablet tell me if I have cavities? Ask the clinician to distinguish plaque from calculus, staining, enamel changes, and decay during an examination.
