Swollen and/or bleeding gums are the first oral symptoms of malnutrition. As the malnutrition continues, the teeth may begin to decay. When only the gums are affected, the oral effects of malnutrition can be reversed; however, once the teeth begin to decay, the damage is permanent.
The density of milk depends on fat content and its type. The density varies from 1.032kg/L (whole milk) to 1.035kg/L (skim milk). This can go as low as 1.026kg/L under cert â¦ ain conditions, but a low density could also indicate added water.
If 10 % of water is added to the milk, the density decreases by approx. 0.003 g/cm 3. Due to the relatively big, natural variations of milk, density watering of milk can only be detected, if at least 15 % water have been added.
