Hello sir.. yellow stains are due to two reasons ..it may be extrinsic stains or intrinsic stains... Extrinsic stains are due to tea, coffee stains deposits(plaque and calculus),smoking stains... Intrinsic stains may be genetic or environmental ( flurosis)... Extrinsic stains can be removed by scaling ...Intrinsic stains can be treated by teeth bleaching, laminates and veneers...

There are basically two types of stains. 1. Extrinsic stain: is staining on the surface of the tooth, it occurs when stain particles such as food/ drinks cover the tooth surface 2 Intrinsic stain: is staining below the tooth surface

Yes it can be done, please visit ur nearby dentist he will manage your stains

If that line is above the tooth surface then it can be clened but if that line is intrinsic stain then it cant be vleaned but can be light by bleaching

yes.. you will need to get it treated either by scaling or bleaching depending on clinical examination of teeth. so please visit a nearby dentist to get it clinically examined.

one has to understand the type of yellow line.there r two types of stains,extrinsic n intrinsic,means outside n inside the tooth. the stains which r outsude means extrinsic can b removed by a procedure called as scaling if stains r internal,inside the tooth then they can not be removed.they can be either masked by laminates or lightened by bleaching a clinical evaluation is a must to come to proper conclusion
