3. Brushing Too Hard
The best habit for everyone, young and old, is to brush your teeth for 2 minutes, twice a day. The bad side of this habit could be if you are brushing too hard, with a hard-bristled toothbrush. Brushing or scrubbing too hard can be harmful to your teeth and irritate your gums, which can contribute to a receding gum line. A soft to medium toothbrush is perfect to avoid this, as well as taking a massage style brushing approach.
