Gum problems can be caused by plaque bacteria that builds up around, on and in between your teeth. If this bacteria is not removed by regular brushing and flossing it can irritate gums, leading to red, swollen and bleeding gums, which are all early gum disease symptoms, known as gingivitis. 

If these signs of gum disease are left untreated, small 'pockets' may develop between teeth and gums. As these pockets deepen it can eventually lead to periodontitis, which is one of the most serious types of gum diseases. Once you reach this stage of gum disease, damage may have occurred, and if left untreated can lead to tooth loss.

This is why it is important to stop this journey at the early stages by to keep your gums healthy.
