Apply to stains for few seconds and rinse.
Minor oral irritations, such as cold sores. - answer avoid areas when
polsinong and retracting tissues or establishing fulcrum. Apply protective

extrinic stains - answer outside of the tooth and can be removed by
scaling and polishing. extrinsic stains are exogenous only.
categories of intrinsic stains - answer dental fluorosis, pulp damaged,
tetracycline, metallic stain
dental fluorosis stain - answer result of high concentration of fluoride
systemically during tooth development; white to yellow-brown or gray
brown.
tetracycline stain - answer high concentration of tetracycline antibiotic
during development; light green or yellow to dark gray- brown
metallic stain - answer intrinsic and/or extrinsic; may be inhaled in
industrial settings or taken orally in certain drugs, or may compromise
part of the materials used to restore teeth.
Categories of extrinsic stains - answer yellow and brown stains, tobacco,
