preparations for cleansing teeth and possess the
largest market share amongst all dentifrices.
Though more expensive than toothpowders yet
toothpastes are more preferred because of the
following reasons:
Attractive consistency.
Better coverage of dental set up.
Easy to take measured quantity on the tooth
brush.
No spillage and wastage.

16. Tooth Powder
Tooth powders are one of the oldest, simplest
and the cheapest dental preparations.
Their market share has been reduced over the
years due to popularity of toothpastes.
Disadvantages of tooth powder are:-
Floating of powders in air during preparation
and use.
Formation of cake on storage.
Uneven distribution in mouth.

17. Formulation of
Toothpowder
The basic ingredients used in tooth powder
are the same except that the binders,
humectants and solvent are not required.
Abrasives used in tooth powders are also same
as in tooth pastes like calcium carbonate,
calcium phosphate, tricalcium phosphate etc.
Heavy grade calcium carbonate is used in
tooth powders whereas lighter grade is used
in tooth pastes.

25. SUMMARY
Dentifrices (e.g. toothpaste) are oral health care products used
to make the teeth appear clean, shiny and attractive. They are
also used for prevention of caries, tooth decay, plaque, tartar
(calculus), hypersensitivity, bad odor, and periodontal diseases.
Dentifrices are available in paste, powder, gel and stick forms.
The basic ingredients of a tooth paste include abrasives,
surfactants, humectants, binding agents, sweetening agents,
flavors and preservatives. In tooth powders binders and
humectants are not required.
Some special ingredients are added in dental products as
desired. These include coloring agents, bleaching agents,
lubricants and therapeutic ingredients.
Dental products should be evaluated for abrasiveness, particle
size, consistency, cleansing action, pH, foaming action,
moisture, heavy metals, effect of special ingredients.
Dentifrices should be used with caution by children under six
years as they have been reported to cause dental fluorosis.
