The main cause for gingivitis development is the bacterial plaque that accumulates in the gap in between the teeth or in small pockets between the tooth and the gums holding it. In turn, these bacteria are feed by remaining food particles in the areas surrounding the teeth that were not properly cleaned out due to poor oral hygiene.
In most cases, teeth are deceptively sparkling and clean, but unseen is an army of bacteria feeding on food particles. These food particles are sometimes too small to be seen by the naked eye and are detected by dentists only through a microscope.
Once the bacteria get to work, the immediate result is an inflammation of the gums and tissues surrounding the teeth. When the condition is ignored, there is an accumulation of chemicals and toxins that can weaken the gums. This weakening of the gums will result to spaces appearing in between teeth.
Over time, the condition may still worsen until tooth and bone loss is experienced. This happens because the bones and gums that support the teeth are now structurally weak. As a result, the teeth fall out or it needs to be extracted lest acute infection will cause an even greater harm to the affected tooth.
