Can I get teeth whitening?

I tend to smile broadly showing my teeth when I laugh, but I'm a bit concerned about the color of my teeth.

I'm interested in teeth whitening and am looking into various products and procedures.

There are also teeth whitening products that can be used at home, but I think the effects are somewhat weaker.

I have weak teeth and gums, is it okay to undergo teeth whitening treatment at the hospital?

I'm often experiencing sensitive gums, and I'm worried that they might become even weaker after the procedure.
