Study looking at teeth provides evidence of lasting damage due to smoking

NEW DELHI: A study has revealed evidence of how smoking can permanently impact teeth, revealing tell-tale signs that remain despite quitting the habit.

A tooth consists of three main hard tissues — enamel, dentine and cementum.

Cementum, which covers the tooth root, develops characteristic ‘rings’ — much like tree rings — that grow each year as we age, researchers from Northumbria University, UK, said.
