Teeth whitening toothpastes generally work through the use of abrasives which physically remove stains from the surface of the teeth.  Toothpastes are required to apply continuously for a period of time till you get that desired effect.  They are recommended for minimal stains such as coffee and tea.  Teeth whitening toothpastes and trays are ideal for those who don´t have time to make it to the dentist’s office.  Toothpastes and products only clean the surface of your teeth and don't have any way to actually whiten the stains below the surface of the enamel.  They remove surface stains and prevent new stains from building up.

Teeth whitening toothpastes seem to be popping up everywhere and you've got to wonder if they really work.  Toothpastes may have additional polishing agents and special chemicals that are more effective against stains than regular toothpastes and they are ideal for people who smoke, drink coffee and tea and eat certain foods that can stain your teeth.  There is validity to some of the whitening claims made by the manufacturers of teeth whitening toothpastes but the process by which these products achieve their effect may be different from that which you'd expect.  Certainly teeth whitening toothpastes can be the best choice for some people in some circumstances.  But before you can make a decision about what is best for you, you will need to know more about how teeth whitening toothpastes work. 

The primary mode of action of teeth whitening toothpastes is one of abrasion.  The formulations of some of them do include peroxide compounds, however only at low levels.  On a comparative basis, teeth whitening toothpastes typically are not considered to be the most effective type of tooth whitening products available, primarily because their effect is only one of removing superficial debris as opposed to creating a true internal color change as is the case with peroxide-based whiteners.  Many dentists believe that these products are a complete waste of time and money.  There are many arguments for and against teeth whitening toothpastes but when considering the questions as to whether or not they work we need to understand the underlying cause and effect of discolored teeth.  When considering the use of them consumers must first understand that discoloration can be as a result of stains to the surface of the teeth or due to the discoloration of the dentin inside the teeth.  The abrasive action of teeth whitening toothpastes help remove stains created by food and drink and polishes the surface of the teeth.  Consumers just need to be aware that they remove stains from the surface of the teeth but do not have any impact on yellowing dentin.  In addition, more abrasive teeth whitening toothpastes may create tooth sensitivity and make teeth appear more yellow through damage to the tooth enamel.
