I am about to get my teeth whitened from a dentist. I was told that 3 layers of some solution will be applied to get the required results. So just want to know how it works? Is it effective? Does it wear off after a few years? How do I maintain my teeth after the procedure?
I just want to get some clarity before I go for it. Please do help if you have knowledge about it.

Basically, active ingredients in the gel applied usually together with UV light destroy the colouring molecules embedded within your enamel. This makes the teeth a little more susceptible to discolouration, so they will usually be treated afterwards to get a kind of protective covering. Still, immediately after the procedure, you should avoid heavily colouring foods like coffee.
Regarding the longevity, you’re still required to keep good teeth hygiene. Teeth can and will discolour again if you’re a heavy coffee trinker or smoker and don’t keep a good hygiene routine.
