While poor oral hygiene contributes to gum recession, it can also happen in people with good oral hygiene due to a number of factors:
Around 88 percent of people 65 years and older have a receding gum in at least one tooth.
The main cause of gum recession is gum disease. Bacterial gum infections destroy gum tissue and supporting bone that hold your teeth in place.
Aggressive Tooth Brushing
Brushing your teeth too vigorously or with a brush that has hard bristles is a common cause of receding gums. Even when dental hygiene might otherwise be good, over-brushing can cause receding gums.
Almost one-third of the population may be predisposed to gum disease due to the position of their teeth and gum thickness.
People who use tobacco products face an increased risk of receding gums as a sticky plaque on their teeth is difficult to remove and can cause gum recession.
