Growth in teeth dysmorphia

A preoccupation with the colour of teeth is commonly recognised as a symptom of BDD (Body Dysmorphic Disorder), a psychological condition where sufferers are fixated about certain aspects of their appearance.

Ken Harris, of Riveredge Cosmetic Dentistry, which has surgeries in both Sunderland and Newcastle, warns that those desperate for bright white teeth should steer clear of using home treatments or the excessive use of whitening toothpastes which can leave them with severe dental problems.

“Whitening toothpastes do not work,” said Ken.

“They clean off surface stains but do not touch ugly deep staining and they are also very abrasive so can wear the enamel off teeth, causing significant damage.

“No amount of tooth brushing can whiten teeth.”

The abrasive nature of toothpaste is measured by RDA (Relative Dentine Abrasivity); in 2012, the British Dental Journal said that toothpastes with an RDA of more than 100 were considered abrasive and could damage teeth and gums.

A number of popular whitening toothpastes on the market have an RDA in excess of 100 so are leaving people in danger of potentially damaging their teeth.
