New research published in The Journal of Clinical Dentistry has found that baking soda toothpastes are more effective in enhancing plaque removal from harder-to-reach areas of the dentition than non-baking soda variants.

1. NEW CLINICAL STUDIES ANALYSIS SUPPORTS BAKING SODA
PLAQUE REMOVAL EFFICACY
New research published in The Journal of Clinical Dentistry (Volume XXII 2011
Number 5) has found that baking soda toothpastes are more effective in enhancing
plaque removal from harder-to-reach areas of the dentition than non-baking soda
variants.
In addition to offering immediate plaque removal benefits, baking soda toothpastes
were also found to remove twice as much plaque after repeated regular brushings
than non-baking soda toothpastes.i
Dental consultant for Church & Dwight Co., Inc, the maker of Arm & Hammer
toothpastes, Dr Graham Barnby says: “The clinical credentials and potential health
benefits of baking soda have been the source of investigation for many years. This
new study provides evidence that the use of baking soda in toothpastes can result in
greater plaque removal than in non-baking soda toothpastes.”
To date, there have been numerous studies to support the efficacy of baking soda as
a mechanism for plaque removal. This new study states that baking soda is a unique
ingredient, clinically demonstrated to remove plaque biofilm present on tooth
surfaces.ii
In all but one of the 24 comparisons carried out, baking soda toothpastes were
relatively more effective in areas with less access by the toothbrush.iii This indicates
that plaque removal is achieved by the action of baking soda in its dissolved form,
rather than due to physical displacement caused by the baking soda crystal.
For 150 years, Arm & Hammer has been the leading baking soda brand in the US.
Baking soda is the key ingredient in each of the carefully formulated Arm & Hammer
toothpastes; a natural plaque-removing product favoured by dentists and hygienists
in the US.
Church & Dwight, the maker of Arm & Hammer oral care products, have developed a
toothbrush to amplify the efficacy of dissolved baking soda. Arm & Hammer SONIC
Spinbrush battery powered toothbrush creates a dynamic fluid action to push
water and toothpaste in between teeth, leaving you with outstandingly clean teeth

2. and healthy gums. When used with a baking soda toothpaste, proven to remove
plaque in hard-to-reach areas, SONIC Spinbrush can offer outstanding plaque
removal and give you a deep clean WOW sensation.
The precision motor driven action delivers 16,000 precision micro-sweeps per
minute. This effective method of the SONIC Spinbrush battery powered toothbrush
to remove plaque is clinically proven to remove up to 90 per cent in areas that are
hard to reach*.
Statistical comparisons found that the 65 per cent baking soda-containing
toothpaste removed significantly more plaque at every site than the non-baking
soda toothpaste.iv
The Baking Soda experts at Church & Dwight have developed the entire range of
toothpastes to harness the simple science of baking soda and all six variants contain
from 20 to 65 per cent baking soda. Arm & Hammer Original Coolmint contains
the highest level of baking soda in the Arm & Hammer range at 65 per cent, and Arm
& Hammer Advanced Whitening Sensitive, launched last year, contains 60 per
cent baking soda, as well as micropolishers, for brighter, whiter teeth.
