WHAT ARE THE ADVANTAGES AND DISADVANTAGES OF BLEACHING?

The advantage of bleaching is that it’s relatively inexpensive and brightens the teeth easily and quickly when it works. But it’s far from perfect: it doesn’t work equally well on everyone, so the results aren’t 100% predictable, and the color tends to fade anywhere between 1 and 18 months after getting the procedure done. People who were born with white teeth that have darkened over the years (from tea, coffee, smoking, red white, etc) have the best results with bleaching, while people with very dark teeth, especially from tetracycline staining, experience the least improvement from this method.
