The variety of toothpastes available means that many people choose a brand based on how effective it is at targeting some of the most common oral hygiene problems such as staining, bad breath, sensitivity and gum disease. They probably do not even give a second thought to the ingredients and the effect they may be having on their teeth and overall oral health.

However, new results from a USA-based independent testing laboratory confirm that people should be concerned with the ingredients in toothpaste and their level of abrasiveness, and how by using a lower abrasion toothpaste, serious oral health issues can be avoided.

All toothpastes contain abrasives; they provide the cleaning power needed to keep teeth clean and help prevent gum disease by removing plaque, stains and debris. However, in the search for the right toothpaste, it’s important to find one that does “all of the above” but is not so harsh that the abrasives attack the enamel.

The development of toothpaste and its abrasive qualities date back as far as the Egyptians in 4th Century AD and the Romans, when the most effective recipes included crushed flowers, bones and oyster shells.  Today, abrasive ingredients include particles of aluminum hydroxide (Al(OH)3), calcium carbonate (CaCO3), various calcium hydrogen phosphates, silicas and zeolites, and hydroxyapatite (Ca5(PO4)3OH), and can account for up to 60 % of some brands of toothpaste.

People should steer clear of highly abrasive toothpastes as they can damage the teeth and gums.  As tooth enamel is worn away, the dentin beneath is more visible and teeth become more yellow in appearance.  They can also remove the luster and polish of porcelain veneers and crowns, dulling an otherwise beautiful smile.  Abrasive toothpastes can also cause teeth to be become sensitive and in the most severe of cases can result in infection and even tooth loss.

The abrasiveness of toothpaste is measured according to the RDA (relative dentin abrasivity) value, and any value over 100 is considered to be “abrasive”.  Unfortunately, the RDA Value is often not included in the marketing or promotional information supplied with toothpaste products, masking what is a common problem.

In the studies performed by a USA-based independent testing laboratory (July 2011; July 2012), a range of whitening toothpastes were tested to compare and evaluate their relative levels of abrasion. The results confirmed that Beverly Hills Formula whitening toothpaste is proven to be less abrasive than some other leading brands of both whitening and regular toothpastes, scoring as low as 90 on the RDA table when compared to some leading competitors which have levels as high as 138 (July 2012) and 147 (July 2011).

These results signal a breakthrough in oral care and aesthetics. Removing stains caused by tea, coffee, red wine or tobacco no longer requires harsh abrasives or bleach, as this new generation of whitening toothpaste offers a more tooth-friendly solution, helping people to restore their teeth to a natural white colour, quickly, safely and effectively.

Choosing a lower-abrasion toothpaste is important in the fight to ensure a healthy mouth and using the wrong type of toothpaste can lead to serious oral health issues. For peace of mind, the Beverly Hills Formula lower abrasion whitening range also contains fluoride to offer fast-acting, long-lasting protection against acid attack, whilst helping to strengthen, re-mineralise and harden tooth enamel for complete tooth protection.
