Worried pupils grind their molars, clench
their mouths, chew pencils and bite their nails, causing gum disease and
jaw problems.
The British Dental Association (BDA) says
children are damaging the protective enamel coating on their teeth. BDA
chief John Hunt told The Mirror: "Anyone grinding their teeth due
to stress should visit their dentist for a thorough diagnosis and
appropriate treatment." He added that dentists can advise on
relaxation techniques and jaw exercises to relieve tension.
British schoolchildren are now taking
more exams than ever before. As well as GCSEs and A-levels, they also
take tests at seven, 11 and 14.
