We recommend a professional dental cleaning every 6 months to ensure optimal oral health. Plaque and tarter develops on a daily basis. It is formed as a mixture of bacteria and food particles; and if left untreated, it can lead to gingivitis, where your gums become inflamed and bleed. The condition becomes more noticeable when you brush your teeth or sometimes when you eat. These are signs of the early stage of gingivitis. Gingivitis is easily treated by having the hygienist scale and polish your teeth every 6 months.
