Gingivitis is usually not painful and hence not detected easily.
Bleeding gums are often the first sign of gingivitis.
Symptoms of gingivitis includes the following -

Inflamed, swollen gums that results in swelling

Bleeding Gums especially when brushing or flossing

Bad breath or halitosis

Bad taste in the mouth

Soft, tender and sensitive gums

Gums that have receded to give the teeth an elongated look.
When the gums become swollen, bleed easily or change from a healthy pink to dusky red it is essential to see a dentist in order to treat and cure the disease, and to prevent further damage.
If left untreated, gingivitis can progress on to
periodontitis, which is a far more serious gum disease capable of causing
tooth loss. It can even elevate a person’s risk of
heart attack and stroke. It has been reported that women with periodontitis could give birth to premature babies in comparison to those without the problem.
All this thanks to the tannin acids (astringent) naturally obtained from different quercus species evaluated and recognized as an effective substance against bleeding gums, inflammation and dental mobility in diabetic and non-diabetic patients.
