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. dental supply companies 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 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 dental 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 dental handpiece 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.

loose teeth treatment

Clinically, patients with periodontitis loose tooth and the general procedure is as follows: an integrated treatment plan is established, and disconnect without reservation in determining the value of the teeth, the first should be controlled plaque, tartar and plaque retention factors that control inflammation in periodontal tissue . Effective control of plaque and other treatment 3 to 6 months after the re-evaluation. In inflammation control, review when action is still reserved for further observation loose teeth, and according to the following different symptoms and dealt with accordingly:
1 loose teeth increases, the gap widened periodontal ligament, alveolar bone height but normal. dental handpiece More commonly associated with the early contact for adaptive changes. Can be selected occlusal grinding adjustment occlusal establish a balance between the alveolar bone benign alterations, periodontal ligament space back to normal, loose teeth reduced.
2 loose teeth increases, the gap widened periodontal ligament and alveolar bone height reduction. Adaptive changes may still be improved through occlusal adjustment.
3 loose teeth increases, the gap normal periodontal ligament and alveolar bone height reduction. This situation was mainly due to alveolar bone height reduction caused by the general election grind without blending. This should be made clear whether the progressive increase loosening. As for the stability of the loose, and patients no obvious discomfort, can not handle. For the small proportion of patients, if obvious bite discomfort, curing light consider making a good, easy to clean plaque periodontal splint.
4 loose teeth increases, the gap widened periodontal ligament and alveolar bone height reduction. The progressive loosening is pathological, should be looking for the cause, decide on the next treatment. Generally do blending or other co splint treatment. Ensure good plaque removal and control of inflammation is an important prerequisite.

missing teeth bite

Generally missing teeth bite mainly refers to the remaining maxillary dental midline midline is not aligned with the teeth, jaw teeth down side to the inside, which not only affects the appearance of the teeth, but also for the normal functioning of oral and periodontal health and Oral health has a great impact. By U.S. dental correction to achieve good results. Reason

(1) early loss of teeth: there will be lack of space, resulting in crowded dislocation.
(2) bad habits: habitual thumb sucking, licking tongue. Jiao lips, bite things, stretching the lower jaw and the bad habit of swallowing, unilateral chewing habits, etc., dental handpiece can cause a variety of malocclusion.
(3) more teeth: teeth can cause multiple teeth, jaw morphology system dysfunction.
(4) Congenital missing teeth: more development and embryo reasons, mostly for lack of third molars phylogenetic degradation.
(5) deciduous teeth: Individual Dental shedding of deciduous teeth are not overdue, for following the eruption of permanent teeth can lead to the obstruction was an ambush, or misplaced eruption.
(6) Rujian tooth wear inadequate: because children eat too soft, so some nipples more teeth than other tooth wear, and thus higher arch occlusal surface, resulting in premature contact, causing the front or side movement, the formation of crossbite.
Missing teeth bite correction method can be used to solve, but very safe, according to each person's situation to determine the correction techniques and methods, it is best to a regular hospital for consultation.

What is the principle whitening

Whitening operating time not very long, only 30 minutes. Cryogenic cold, completely avoid the operation process of the tooth nerve stimulation. The main component of the whitening agent hydrogen peroxide

, Bleaching the teeth on safe use for several decades. Hydrophilic gums drugs and no contact whitening process, dental handpiece the tooth structure and the enamel will not cause

Any harm. Disposable, no stimulation, no side effects of the whitening effect lasts more than two years. So is recognized as the most effective and safest whitening teeth bleaching techniques

Surgery.

Whitening teeth do not hurt, no side effects, is a good choice for tooth discoloration farewell
Teeth whitening is a kind of absolute security technology, both on the teeth or soft tissue of the gums will not bring irreversible damage, not for individual enamel development

Liang, cracked teeth, teeth with moderate abrasion resistance, the treatment process will be greater than the normal tooth discomfort, such as pain, tenderness, etc., but will be within 24 hours after surgery

Self-healing, so do not worry there are no side effects teeth whitening problems.

the dental drill

Bur John Greenwood was the first U.S. president George Washington's dentist. Washington made his dentures and used by his mother's spinning machine to change

Made a wonderful device for the Washington dental drill.
Greenwood pedal pedal driven dental drill. However, his device does not promote the use of dental doctors still hand turning the handle to drive the dental drill. Anesthesia

Drugs used first by the fact thatdental handpiece  the dentist, indicating early dental drill and make painful extractions.
In 1858, George Harrington invented the first motor-driven dental drill. Dental drill attached to the dentist's hand holding a watch-like device. Other

The motor-driven `have invented dental drill. Some are electric, some pneumatic. Today's dental drill speed is very fast, so you need to use ice water jet to

Prevent the drill bit temperature is too high. The application of local anesthetic so that the patient does not feel pain almost.
