Firstly clear that normal tooth colour is pale yellow and not white. Secondly whitening and scaling are two very different things. Whitening is a process for internal stains while scaling and polishing is done for external stains. Find out which stains you have and Ultimately the treatment. Any habit of smoking, chewing tobacco etc should be stopped. Brush twice and maintain oral hygiene

There is a confusion in most of the youth about yellow teeth , some yellow stains are more prominent and it could be due to fluoride minerals in drinking water and another yellow stains which are lighter in shade,  this shade is a dentin part inside the enamel. There are three layers of crowns of a teeth . The white portion is enamel the outer layer, middle portion is dentin which is yellowish in colour and inner portion is pulp. So wat happens sometimes that if dentin portion is thick and enamel portion is thin then the yellow shade reflects from the enamel layer so sometimes teeth have yellowish hue which is natural, so still if u feel odd about it then u can go for cosmetic treatment to make Ur teeth white... So without clinical examination it cannot be defined which treatment u require....

I think if there no problem at all,like flulorosis etc,and if u don't want to get the scaling done,then u can use Toothpaste named ShyNM,or Glowdent

Hi, yellow stains you are talking about can be be acquired due to habits/food/ tea etc or internal due to high fluoride content in water or some medication in early years of life.

There is no toothpaste for tooth whitening. Once enquire about the yellow stains what has caused it and what is the reason. If they are stains from within then you can go for laminate or veneer on your anterior teeth to have a better white effect. Do not use the home remedies as they will be temporary

these might be external stains or internal ones.you can go for bleaching for external stains. consult nearby dentist who will give you best advice after checkup.
