Teeth whitening is a very popular cosmetic dental procedure. Dental Whitening procedures fit within almost any budget and the results are quick and painless. There is a difference between teeth whitening and teeth bleaching. Whitening means to brighten your teeth by polishing away stains caused by foods and beverages (berries, coffee, wine, tea, etc). This stain removal whitens teeth back to their naturally white stage. Bleaching refers to lightening a tooth from the inside-out using in-office and take home materials. Bleaching brightens the inside (dentin) of the tooth, thereby making the whole natural tooth whiter.
