A More Gentle Approach
While any dentist would be happy with a patient who is dedicated to regular brushing and flossing, there is such a thing as being too strenuous with brushing. If you are brushing your teeth too aggressively, your forceful approach may contribute to gum recession and other problems. Gum recession associated with vigorous tooth brushing is most likely to appear in the area of the back teeth opposite the brushing hand. You may also be experiencing heightened sensitivity to cold drinks. To avoid these problems, try brushing your teeth with a soft-bristled toothbrush and light pressure for two to three minutes at a time. Using your non-dominant hand may help you pay better attention to your brushing technique.
For many, a powered toothbrush is a good alternative to a manual brush. It can do a better job of cleaning teeth, particularly for those who have difficulty brushing or who have limited manual dexterity. You need to replace your toothbrush when it begins to show wear, or every three months, whichever comes first.
Another sign of aggressive tooth-brushing is a toothbrush with squashed, splayed bristles.
