Dental Hygiene Mistakes to Avoid Aggressive brushing can erode enamel and irritate gums, leading to sensitivity and gum recession. Not flossing allows plaque and food particles to build up between teeth, increasing the risk of cavities and gum disease. Using an old or worn toothbrush reduces cleaning effectiveness and may harbor bacteria. Brushing immediately after consuming acidic foods can wear down softened enamel. Bacteria can accumulate on the tongue, causing bad breath and affecting oral hygiene.
