What causes receding gums?!
It might be a gum disease, but it can be caused by other reasons such as:
1. Periodontal diseases. That means bacterial infection in the gums. They cause damage to the supporting bone of the tooth and the gums, followed by other problems.
2. Lack of oral hygiene. If you skip teeth brushing and flossing you might build up plague on the teeth. That can lead to calculus which is a hard substance which can lead to gum recession.
3. Aggressive brushing. It is the complete opposite of brushing teeth on regular basis. If you brush your teeth aggressively then the enamel on your teeth will be destroyed and this will lead to receding gums.
4. Sometimes you will blame the genes. In this case you cannot change a lot about your problem.
5. Hormone imbalance can lead to receding gums. This can be a huge problem especially among women. Those changes lead to more vulnerable and sensitive gums.
6. Smoking is also a reason for receding gums. Smoking also causes many other diseases such as lung disease and cancer, but it can also cause receding gums. People, who consume tobacco in any form, can get sticky plague on their teeth more easily and this leads to receding gums.
7. Clenching and grinding your teeth will put pressure on them and this can cause receding gums. Using force to take bits while you eat may also cause the same problem.
8. This is a weird reason, but piercing your tongue or lips can also lead to the same problem.
