Teeth whitening is ideal for people who have healthy, unrestored teeth (no fillings) and gums. Individuals with yellow tones to their teeth respond best. But this cosmetic procedure is not recommended for everyone.It's never been easier to brighten your smile at home. There are all kinds of products you can try: rinses, gels, chewing gum, toothpastes, and strips.Virtually everyone who opts for a teeth whitening solution sees moderate to substantial improvement in the brightness and whiteness of their smile. That said, it's not a permanent solution to discoloration and requires maintenance or "touch-ups" for a prolonged effect.
