WISDOM TEETH IMPACT


Wisdom teeth are the last adult teeth to come into the mouth (erupt). Most people have four wisdom teeth at the back of the mouth — two on the top, two on the bottom.
Impacted wisdom teeth can result in pain, damage to other teeth and other dental problems. In some cases, impacted wisdom teeth may cause no apparent or immediate problems. But because they're hard to clean, they may be more vulnerable to tooth decay and gum disease than other teeth are.
Impacted wisdom teeth that cause pain or other dental complications are usually removed. Some dentists and oral surgeons also recommend removing impacted wisdom teeth that don't cause symptoms to prevent future problems.

Symptoms

Impacted wisdom teeth don't always cause symptoms. However, when an impacted wisdom tooth becomes infected, damages other teeth or causes other dental problems, you may experience some of these signs or symptoms:

Causes

Wisdom teeth (third molars) become impacted because they don't have enough room to come in (erupt) or develop normally.
Wisdom teeth usually emerge sometime between the ages of 17 and 25. Some people have wisdom teeth that emerge without any problems and line up with the other teeth behind the second molars. In many cases, however, the mouth is too crowded for third molars to develop normally. These crowded third molars become trapped (impacted).
An impacted wisdom tooth may partially emerge so that some of the crown is visible (partially impacted), or it may never break through the gums (fully impacted). Whether partially or fully impacted, the tooth may:
  • Grow at an angle toward the next tooth (second molar)
  • Grow at an angle toward the back of the mouth
  • Grow at a right angle to the other teeth, as if the wisdom tooth is "lying down" within the jawbone
  • Grow straight up or down like other teeth but stay trapped within the jawbone

Complications

Impacted wisdom teeth can cause several problems in the mouth:
  • Damage to other teeth. If the wisdom tooth pushes against the second molar, it may damage the second molar or increase the risk of infection in that area. This pressure can also cause problems with crowding of the other teeth or require orthodontic treatment to straighten other teeth.
  • Cysts. The wisdom tooth develops in a sac within the jawbone. The sac can fill with fluid, forming a cyst that can damage the jawbone, teeth and nerves. Rarely, a tumor — usually noncancerous (benign) — develops. This complication may require removal of tissue and bone.
  • Decay. Partially impacted wisdom teeth appear to be at higher risk of tooth decay (caries) than other teeth. This probably occurs because wisdom teeth are harder to clean and because food and bacteria get easily trapped between the gum and a partially erupted tooth.


  • Gum disease. The difficulty cleaning impacted, partially erupted wisdom teeth increases the risk of developing a painful, inflammatory gum condition called pericoronitis (per-ih-kor-o-NI-tis) in that area.

3 SIGNS OF WISDOM TEETH is GROWING WHAT SHOULD YOU DO!??? AND YOU NEED TO KNOW!?

Your wisdom teeth growing in is often not a straightforward affair, however. When your third molars are not in the right position to erupt properly, they can partially erupt and provide a place for bacteria to grow, which leads to infection. Wisdom teeth can also become impacted under gum and cause all sorts of oral health issues. Being able to identify the  warning signs of impacted wisdom teeth  is important, but just as important is being able to tell what the normal signs of wisdom teeth growing in are. You’ll need enough information to be decisive about the matter, because time is of the essence when it comes to getting these molars removed. 1. Sensitivity and Swelling If there’s swelling at the back of your mouth on one or both sides, often accompanied by minor discomfort, then this is a key sign that you’re experiencing your wisdom teeth growing in. People liken the sensation to being alike to what they assume teething must be like for an adult. If you cat...

Diseases and some type of it

A disease is a particular abnormal condition that negatively affects the structure or function of part or all of an organism, and that is not due to any external injury. Diseases are often construed as medical conditions that are associated with specific symptoms and signs.

Overweight and obesity (causes, environment and prescription)

Overweight and obesity are terms used to describe ranges of weight that have been shown to increase a person’s risk of certain conditions and health problems. Body Mass Index (BMI) is a useful measure of overweight and obesity for adults. It is calculated from a person’s height and weight. BMI Classification Below 18.5 Underweight 18.5 – 24.9 Healthy weight range 25.0 – 29.9 Overweight 30 and above Obese While BMI provides a good estimate of body fat for most people, it may not be suitable for some groups such as athletes who have a muscular build, older people and some ethnic groups. Waist circumference is another good indicator of total body fat and can be a better predictor of health risk than BMI. For tips on how calculate your BMI and measure your waist circumference, see  assessing your weight . Impact on health Being overweight or obese can increase the risk of physical and mental health problems such as: heart disease high blood pressure high cho...
