In 2001, 91.0% of the population were born in Northern Ireland, 7.2% were born in other parts of the UK and Ireland, and 1.8% were born elsewhere. By 2011, the number of immigrants from outside the UK and Ireland had risen to 4.3%, while the number born within them fell to 6.7%.
The science supports what professionals have been seeing chair-side for years. The WaterpikÂ® Water Flosser is an easy and more effective alternative to string floss. Clinical studies show that the Water Flosser is up to: 51% more effective than dental floss for reducing gingivitis.
Where Theyâre Different. Flossing is pretty straightforward, itâs basically a piece of string that goes between your teeth, cleaning out any food particles that managed to get stuck in there, and scraping up against your teeth to clean them. Waterpik uses a fine stream of water and shoots it between your teeth.
