People looking to improve the brightness of their smile have been advised that teeth whitening works. 
People hoping to whiten their teeth using well-rounded oral health routine and the help of some whitening toothpaste can take heart that the method does work.
A blogger on Truth In Aging stated that she spends two minutes each night brushing her teeth using whitening toothpaste and targets difficult stains with teeth whitening strips.
“Afterward, my teeth seem more polished (due to sodium bicarbonate), protected (from attack by bacteria) and sparkling. Specific stains fade within a week and my oral hygiene appreciates the added step,” the unnamed blogger wrote.
However, she did advise not to be overly vigorous with whitening procedures, as sensitive gums can be extremely painful.
Elsewhere, the Chicago Tribune recently reported that individuals who suffer from asthma could use teeth whitening toothpaste to help tackle their symptoms.
The publication noted that these toothpastes contain saltpetre – a compound which was advised in the treatment of asthma and arthritis for many years.
