Yellowish stains on teeth could either be external or internal.
In case of external stains or tartar on teeth, scaling and polishing I.e. cleaning is required to be done at the dental clinic. It is recommended to have your teeth cleaning done every 6 months to maintain good gum health.
In case of internal stains, you may have to go for bleaching where the basic tooth colour changes.
