What does it mean when you dream about decay?

Decay may symbolize the degradation of a situation. More positively, it represents the death of an old situation before rebirth into a new state. Other associations come from such common idioms as “rotten apple.” (See also Maggots).

decay

(geochemistry)
(materials)
To undergo decomposition.
(nuclear physics)
(oceanography)
In ocean-wave studies, the loss of energy from wind-generated ocean waves after they have ceased to be acted on by the wind; this process is accompanied by an increase in length and a decrease in height of the wave.
(physics)
Gradual reduction in the magnitude of a quantity, as of current, magnetic flux, a stored charge, or phosphorescence.

Q: What might people find most surprising about tooth decay?
For a long time, we have lacked a fundamental understanding of nuclear beta decay, said EMMI professor Achim Schwenk from TU Darmstadt, who is part of the collaboration.
According to the American Academy of Pediatrics, tooth decay can develop as soon as the first tooth shows itself.
First of all, the act of chewing gum stimulates your saliva production, which helps to neutralize and wash away acids on the teeth that could cause decay. Your teeth get extra protection when you chew sugar-free gum that's sweetened with xylitol, a sugar substitute that prevents decay by stopping acid production, decreasing bacteria and enhancing the remineralization of teeth, as detailed on WebMD.
What's certain for now is "State of Decay 2" is scheduled for release on May 22 for both Xbox One and PC.
Ms Gibson said the statistics "can only be described as appalling" and that while tooth decay is preventable, it is a "serious problem" that is linked to health inequalities.
According to the Centers for Disease Control and Prevention (CDC), adding fluoride to the water supply has dramatically reduced the prevalence of tooth decay over the past 70 years.
Urban Decay is just as famous for its punchy lip colours, so we're including 10 of its best-selling Vice Lipsticks.
Cwm Taf University Health Board, which covers Rhondda Cynon Taff and Merthyr, was the only health board in Wales not to see a "statistically and clinically significant reduction" in tooth decay levels among this age group.
Chief Dental Officer for Wales, Dr Colette Bridgeman said: "We are refocusing Designed to Smile on the 0-5 age group, restating the overarching aim of the programme, to keep children decay free by the age of five."
The researchers said that application of high concentration fluoride varnish by dentists to the sites of early decay, attention to home tooth brushing skills, restriction of between-meal snacks and beverages containing added sugar, and risk-specific monitoring can help prevent tooth decay.
