The consumption of very acidic foods and beverages can promote tooth erosion and brushing teeth too hard can promote receding gums.  Your teeth can be left vulnerable to decay if your gums recede too far and it is always a good move to know how to repair and fix receding gums.  But remember that prevention is always better than cure. Tooth decay prevention is important to avoid receding gums from happening. You can avoid tooth decay by brushing your teeth twice a day, clean teeth in between using a dental floss everyday, eat balanced and nutritious meal, limit having a snack, have your teeth and gums checked by your dentist for professional cleaning and oral examinations.
