In figure 1 above, the more electronegative Oxygen atoms pull electron density towards themselves as demonstrated by the arrows. Carbon Dioxide is not polar however because of its linear geometry. A molecule's overall dipole is directional, and is given by the vector sum of the dipoles between the atoms.
There are a number of factors that can cause your gums to recede, including: 1  Periodontal diseases. 2  These are bacterial gum infections that destroy gum tissue and supporting bone that hold your teeth in place. 3  Gum disease is the main cause of gum recession.

It seems that the pathogens connected with inflamed gums can generate inflammation in the brain cells, resulting in Alzheimer's disease. There are numerous thoughts on the causes of dementia, but staying on top of dental problems is one of the easiest ways to lower your chances of developing this devastating diagnosis.
