Due to plaque and calculus, the gums and bone around the teeth recede and gaps are caused between the teeth. However, as the calculus covers those gaps, they are not visible. When the dentist cleans the teeth and removes the Calculus, the gaps among the teeth become visible. This gives the impression that teeth move apart due to cleaning or scaling. This is not true. If one does not get one�s teeth cleaned and the Calculus remains for a longer time, it would affect the neighboring healthy teeth and they would fall.
