Excellent products

Right place for tooth care products.Simple suggestions ,most simple solutions .My problem is stains and yellow color type in root point of tooth.
I am not yet sure either this will end with permanent solutions.After using toothpaste and whitening stripes set and ivo mouthwash .As many products i had already changed in last six years and almost lost confident on such treatments.Doesnot mean these products are not effective ,problem is ,after a frequent intervals issues return back in same condition.
Four days of applying these three products I can notice changes, again I am very hopefully ,probably this could be my last products who can free me from these stupid and irritating problems.
