When you think about allergies, you probably think of a runny nose, itchy eyes, and sneezing. But they can also take a toll on your voice in several ways: 1  An allergic reaction can cause your vocal cords to swell.  Postnasal drip -- when mucus moves from your nose into your throat -- can irritate your vocal cords.
Smoking and other tobacco products can lead to gum disease by affecting the attachment of bone and soft tissue to your teeth.More specifically, it appears that smoking interferes with the normal function of gum tissue cells.This interference makes smokers more susceptible to infections, such as periodontal disease, and also seems to impair blood flow to the gums-which may affect wound healing.ore specifically, it appears that smoking interferes with the normal function of gum tissue cells.

1 Gum Bleeding. 2  Bleeding of the gums, even during brushing, is a sign of inflammation and the major marker of periodontal disease. 3  One exception is juvenile periodontitis, in which symptoms are mild or even absent. 4  It should be noted that the gums of smokers with periodontal disease tend to bleed less than nonsmokers.everal other conditions can also cause gum inflammation, and some have been associated with periodontal disease. They include: 1  Mouth breathing. 2  Psychologic stress. 3  Stress can affect the immune system. 4  Some studies suggest that stress can influence the development of chronic inflammatory diseases, like periodontitis.
