what is the cavities

1 What is the formation of cavities?
   There are four conditions for occurrence of dental caries: bacteria, food, teeth, time. Under normal circumstances, the people of the many oral bacteria, there is a acid-producing bacterium which is also known as cariogenic mutans bacteria. When the food residues present in the surface of the teeth for a long time, cariogenic bacteria and food carbohydrates will react to produce acid, these acids react with the enamel, making demineralized enamel surface, softening, disintegration, forming shallow cavities, then the general feeling no pain, not easily found. If this time is not treated, cavities will grow larger and more deep, superficial damage to the dentin, then eat hot and sour spicy food, the teeth will feel sore. If you still ignore and undermine the pulp, causing pulpitis, there will be  dental a spontaneous severe pain.
2 teeth with holes is not to wait for the pain to fix?
    Not. The teeth have holes to fill in time, you should not wait until the pain to fix. Once a toothache, you need to kill the nerve to do root canal treatment, so that not only the treatment of complex, and the cost to increase, more harm than good. So to the problem in the bud, put it to get rid of, do not wait complexity of the problem, and then solved.
3 teeth hurt too nervous to kill you?
    Depending on the circumstances. Teeth hurt does not mean there is no problem nerves, according to the doctor checks to determine the state of the pulp symptomatic treatment. In general, the pulp is infected, you need to remove the pulp (ie kill nerve) is more likely.
4 teeth have holes, why was it not hurt?
    The outermost layer is called Acrylic resin teeth enamel, which is no distribution of nerve endings. When cavities located on this floor, people generally do not feel pain. Enamel called dentin layer below, and its distribution within the nerve endings, so it is sentient. Development of this period will not be spontaneous cavities usually pain, but encountered cold, hot, sour, sweet pain can occur when stimulated, more obvious when cold, when the food embedded into cavities also occurs pain. If cavities deeper cause chronic pulpitis or pulp necrosis and chronic periapical, the teeth but not too painful.
5 How to prevent cavities produced?
    First, develop good oral hygiene habits is the most important. Brush your teeth after a meal before going to bed, to develop the habit of flossing, thus removing the food this cariogenic conditions. Secondly, the use of fluoride toothpaste for teeth. Fluoride and calcium binding in the tooth can enhance the ability of acid-resistant teeth. Third, there are some teeth, structural defects, such as deep fissure. Sealant can be prevented. Another irregular teeth can easily lead to clean difficult, orthodontics can solve this problem.

Phones (non-phone use cellphones more types of structure can be divided according to speed and high-speed and low-speed mobile phones, high-speed mobile phone using high pressure air driven handpiece for micro turbine may turbine speed up (3-5) × 10r/min, bur cutting line speeds of up to 15m / s, while the low speed gears because it is mobile, speed of only thousands of revolutions per minute.) 4.LED light curing 5. Ultrasonic Scaler
Orthodontics, then of course the younger effects out faster the lower the degree of recurrence, 16 years old dental Composite can also be fairly active bone remodeling, in general, across the line will be improved after orthodontic, do not worry.
If more severe congestion may require removal of some of the teeth, aligned it'll be better looked after, if you still feel bad teeth appearance can do porcelain teeth, but most of the dentition will not affect the development of dental morphology, but it feels awkward position is not normal.
