Products and advertisements about teeth whitening tempted many of us and it’s no question it is considered the latest craze in town. This is so with the promise of a dazzling Hollywood smile, however, not everyone has the opportunity to launch into whitening teeth. There are those who should be warned to wait for their perfect time before going into any teeth whitening system. They include (1) children under 12 years, (2) people with tooth-colored veneers, fillings, caps or crowns, (3) pregnant women, and people with receding gums. This group seems to be at increased risk of sensitivity to teeth bleaching. Those born with natural sensitivity may not be able to tolerate bleaching.
