Many people have crowded or crooked teeth. Here at Purity we understand that having your teeth straightened can improve your appearance and boost your self esteem. Straight teeth are also easier to clean, so they are less vulnerable to tooth decay and gum disease. Orthodontic treatment straightens the teeth or moves them into a better position.This usually involves wearing a brace (appliance) which puts gentle pressure on specific teeth to move them into the right place. At Purity orthodontic treatment is available, free of charge on the NHS for young people who are under 18 years of age and who have a clear clinical need for treatment.A rating system, known as the Index of Orthodontic Treatment Need (IOTN), is used to assess the need and eligibility of individual cases. For those who do not fall into the rating system, Purity offers orthodontic treatment for both children and adults at a very competitive rate.
