Here are a few reasons of how gum recession can happen and how you can prevent it from happening:
1. Aggressive brushing
Brushing vigorously can damage and push the gum which causes the root of the tooth to be exposed and in the long run, that will lead to tooth sensitivity.
Solution: Buy a toothbrush with soft bristles and brush your teeth and gums gently. Brushing time should be 2 minutes. Floss after you are done with brushing to remove plaque from hard-to-reach areas.
2. Periodontal Disease (Gum Disease)
Gum disease causes gum inflammation and if left untreated, it will lead to gum and bone loss which will cause loosening of the teeth.
Solution: To find out if you have gum disease, make an appointment to have a dental examination done. Your dentist or hygienist will discuss your oral condition with you, so you can have a better understanding of the diagnosis.
3. Poor Oral Hygiene
Inadequate dental care which includes poor brushing habits, lack of using dental floss and infrequent visit to the dentist makes it easier for plaque to turn into calculus which requires professional cleaning by the dentist to remove it.
Solution: Maintain a 6 monthly routine dental visit for oral examination and professional cleaning. This would also allow your dentist or hygienist to keep track of your oral health.
