is it worth getting my teeth whitened?

I'm going on holiday for a few months to thailand would it be a good idea to get my teeth whitened there as ive heard that it is cheap and where i live its very expensive (uk) many thanks

you could just simply get your teeth whitened with whitening strips such as crest whitening strips. they truely work! its great and only like $20-40 a box. after my teeth were white, i loved smiling and looking at how white they are. :) p.s. to keep the whitening, use whitening toothpaste too.
