Best dental cleaning in kovilambakkam. Is scaling and polishing necessary if I brush my teeth everyday? Yes. While thorough brushing and regular flossing helps to reduce the buildup of plaque, toothbrushes and floss cannot reach certain small spaces between the teeth. Plaque can accumulate in these spaces and harden to form tartar, and these can only be removed by scaling. Stains on the teeth that can only be removed by polishing could also lead to oral complications if left untreated
