Can you swallow disclosing tablets?

Don't swallow, but spit out the mixture and rinse well with water. Look at your mouth under good light and check where the dye is darkest. With two-tone disclosing tablets, usually old plaque is blue and new plaque is red. Brush and floss your teeth again, focusing on the stained areas until all the dye has gone.

How do you use disclosing tablets?

Chew a tablet (or just one half for adults, a quarter for kids) then swish around with saliva for 30 seconds before spitting out. Rinse gently with water – then check your teeth in good light for areas highlighted with the bright pink/purple stain. Finally, brush again to get a truly bright white smile!
