ISMILE shanghai dental finds the most common cause of gingivitis is poor oral hygiene that promotes plaque to form. Plaque is an invisible, sticky film composed mainly of bacteria. Plaque forms on your teeth when starches and sugars in food interact with bacteria normally found in your mouth. Brushing your teeth at least twice a day and flossing each day removes plaque. Plaque need to be removed daily because it reforms fast, usually within 24 hours.
Plaque that lurks on your teeth more than two or three days can harden under your gum line into tartar (calculus). Tartar can also develop resulting from the mineral content in your saliva. Tartar makes plaque harder to clean and creates a protective shell for bacteria. You usually can't eliminate tartar by brushing and flossing — you need a professional dental cleaning to get rid of it.
If plaque and tartar stay on your teeth longer, they irritate the gingival further, the part of your gum around the root of your teeth. In time, your gums become swollen and bleed easily. Dental caries also may appear.
Some other common reasons are listed as follows:
1.,Smoking or chewing tobacco hinders the gum tissue from being able to heal.
2.,Hooked, rotated, or overlapping teeth create more space for plaque to accumulate and are more difficult to keep clean.
3.,Stress damages the body's immune response to bacterial assault.
4.,Mouth breathing can be harsh on the gums when they aren't protected by the lips, causing chronic inflammation.
5.,Poor nutrition such as a diet high in sugar and carbohydrates and low in water intake will speed up the formation of plaque. Also, the deficiency of vital nutrients will obstacle healing, especially vitamin C.
6.,Diabetes weakens the gums healing ability.
7.,Medications promote gum disease, such as antiseizure medications
8.,Dry mouth: because of loss of protective effect of saliva
There are also some rare causes as follows: reaction to oral contraceptives, Gingival hyperplasia caused by medications, Leukemia and other rare blood disorders as well as systemic causes: metabolic disorders such as thyroid disorders or diabetes or nutrient deficiencies, or HIV infection.
Some people are more prone to getting gingivitis than others. Gingivitis is particularly likely to occur in people with diabetes, AIDS, or leukemia. Other factors linked to an elevated risk of gingivitis include: genetics, allergic reaction (e.g., cinnamon gum), niacin (vitamin B3) deficiency (pellagra), medications (e.g., use of the female contraceptive pill) and some medications are also associated with gingivitis, including some medicine used to treat rheumatoid arthritis and other autoimmune diseases or used to control epilepsy and other seizures or used treat high blood pressure and other heart conditions.
Some viruses can also infect the mouth. The one most likely to attack the gums is the herpes virus. It causes tiny ulcers and holes to appear in the gums and other parts of the mouth. But as a matter of fact, gingivitis is not a serious disease, so due attention will keep it far away from us.
