Teeth-whitening toothpastes offer an at-home solution to brightening smiles.

Teeth-whitening toothpastes can brighten the outer enamel layer of your teeth, removing the discolouration associated with surface stains incurred from tobacco, coffee, wine and tea.
Different whitening toothpastes claim to offer a brighter smile in a specified period of time with daily use. A typical time frame to see a difference in appearance is two to four weeks, although some teeth-whitening toothpastes can offer immediate results using specific ingredients.
Special abrasives in teeth-whitening toothpastes can expedite the removal of surface stains by polishing the outer enamel. Sodium tripolyphosphate, a chemical found in some whitening toothpastes, can produce brighter teeth by breaking down stains. Blue covarine, another chemical agent found in some whitening toothpastes, adheres to the surface of the tooth and immediately creates the impression of whiter teeth without removing surface stains.
Excessive brushing with teeth-whitening toothpaste will erode the tooth enamel and can cause additional damage. If teeth-whitening results are not achieved with whitening toothpastes, consult a licensed dental health practitioner to explore other teeth-whitening options.
