ABSTRACT
This chapter focuses on the tooth whitening techniques used for teeth with existing white, brown, and orange spots and discusses whitening techniques, microabrasion, and resin infiltration for the eradication of the white spots. Whitening treatment improves tooth color by lightening, whitening, and brightening the teeth. Unlike microabrasion, whitening preserves the intact fluoride-rich layer of enamel and the tooth shape. Normally it is best to undertake whitening first because home whitening treatment may eradicate the lesion completely. Once the whitening treatment is completed, then microabrasion can be undertaken. Tooth whitening normally removes the brown, orange, and yellow stains that are present on the tooth first, and then the natural color of the tooth lightens. The white spots can be treated after whitening with amorphous calcium phosphate in the same whitening trays to reduce the appearance of the white spots. Microabrasion can be used to remove or reduce in size the remaining white areas after the whitening process.
