Plaque is a soft and sticky substance that collects around and between teeth. The home dental plaque identification test shows where plaque builds up. This helps you know how well you are brushing and flossing your teeth.
There are two ways to perform this test.
In the office, dentists are often able to detect plaque by doing a thorough exam with dental tools.
Brush and floss your teeth thoroughly.
Your mouth may feel slightly dried out after using the dye.
The test helps identify missed plaque. It can encourage you to improve your brushing and flossing so that you remove more plaque from your teeth. Plaque that remains on your teeth can cause tooth decay or make your gums bleed easily and become red or swollen.
No plaque or food debris will be seen on your teeth.
The tablets will stain areas of plaque dark red.
The plaque light solution will color the plaque a bright orange-yellow.
The colored areas show where brushing and flossing was not sufficient. These areas need to be brushed again to get rid of the stained plaque.
There are no risks.
The tablets may cause a temporary pink coloring of your lips and cheeks. They may color your mouth and tongue red. Dentists suggest using them at night so that the color will be gone by morning.
