Dental Health
How do you know if you need braces?
People may need braces if they lose their baby teeth later than normal, if they experience abnormal jaw clicking or if their bite does not close in a matched pattern, according to Delta Dental. Chewing problems or biting the cheeks are additional indicators that braces may be necessary.
People with crooked teeth or teeth that are pushed out of a row commonly require braces to realign the teeth, notes Delta Dental. The majority of teeth and jaw complications are inherited genetically from a parents, but detrimental habits such as thumb-sucking can also cause the need for braces. Some people suffer from extreme malnutrition or experience injuries that require braces to fix their dental problems.
Disproportionate jaw shapes or bite complications such as overbites or under bites are often treated successfully with braces. WebMD stresses the importance of braces in preserving the health of patients' teeth, especially if adults are suffering with chronic misalignment. If these conditions go untreated, they can lead to poor overall dental health through plaque build-up, periodontal disease and gum disease. Continued jaw imbalances can cause painful headaches and muscle tension.
As of 2014, orthodontists have several options available to correct dental issues, such as metal braces, clear braces and removable aligners. Adults pay an average of $4,800 for a set of braces, according to WebMD.
Question of the Day!
Why is there a pot of gold at the end of a rainbow?
In Irish mythology, the pot of gold is hidden at the end of a rainbow by a small member of the fairy family called the leprechaun. Humans who are lucky enough to spot a leprechaun by following the rainbow may still have problems catching him because the fairies bestowed upon leprechauns the magical ability to disappear.
In Irish mythology, the leprechaun is considered a trickster who often appears at night and is the cause of small mishaps around the house. The leprechaun is most often depicted as a very small old man wearing a leather apron and dressed in green. He usually has large silver buckles on his shoes. Although wary and mistrustful of humans, the leprechaun is known to occasionally ride sheep or even the family dog for sport. All leprechauns love gold and have their very own pot. Even though the rainbow tells people where the pot is, humans have to catch the leprechaun first in order to find it. Since fairies granted leprechauns the magical ability to grant three wishes or disappear, it is next to impossible for a person to actually find the pot of gold at the end of the rainbow. Nevertheless, seeing a rainbow is still considered by many to be a sign of good fortune or luck.
In reality, the end of the rainbow is an unreachable illusion. A rainbow is created when sunlight reflects off water droplets. It is not an actual physical object that one can touch, but rather an optical illusion that is seen only from a certain angle. As a person tries to approach the end of a rainbow, it appears to move farther away. The colors of the rainbow, in order, are red, orange, yellow, green, blue, indigo and violet.
Information Overload
How much does the Internet weigh?
The Internet, as of 2011, weighs less than 2 ounces, according to the personal blog of the Harvard University physics professor Dr. Russell Seitz. This measurement includes a consideration of the data that makes up the Internet, which Seitz says consists of about "50 grams of electrons in motion," and that the silicon circuitry that makes the Internet function contributes a little more weight, leading to a final figure of under 2 ounces. The process of calculation is complicated by the fact that devices that are able to connect to the Internet vary in speed and may not always be in use.
Measuring the actual physical weight of the Internet is a difficult task due to the fact that the Internet, rather than being a fully tangible thing, is a collection of data and electronic code. However, though data is not necessarily visible to the naked eye if it is not being processed through a computer, it is a physical thing that does have weight, albeit an infinitesimally small weight. In order to determine the weight of the Internet, a researcher may need to define parameters for the experiment, such as the weight of all the data transferred over the Internet over the course of a 24-hour period.
