Why and How Dental Caries Formed?

Why and How Dental Caries Formed?

Knowing how to take care of your teeth is very important, but knowed why and how dental caries formed is something more important.

Caries is a transmissible infectious disease, the most common affecting the teeth, in which the acids produced by bacteria dissolve the teeth.

Some bacteria such as Streptococci mutans and Lactobacilli, can be transmitted, for example, from parents to children. These bacteria are cariogenic (which means decay-causing) and create a sticky film known as plaque on the surface of the teeth. The bacteria in plaque feed on fermentable carbohydrates and convert them into acids. Fermentable carbohydrates are sugars and other carbohydrates from food and drink, bacteria can ferment. The acids formed dissolve minerals such as calcium and phosphate from teeth. This process is called demineralization.

But tooth decay is not inevitable. Saliva carries food debris left in the mouth, neutralizes acids produced by plaque bacteria and provides calcium and phosphate to the teeth in a process known as remineralization. Saliva also acts as a reservoir for fluoride toothpaste or fluoridated water. Fluoride helps control remineralising tooth decay and inhibiting bacterial acid production, which reduces or stops the decay process.

Tooth decay only occurs when demineralisation exceeds remineralisation over a period of time.

Cause of Dental Caries

Cause of Dental Caries

The following factors have an important effect on dental health:

1.Individual factors

The risk of decay varies between individu and between different teeth within a mouth. The shape of the jaw and oral cavity, the tooth structure and the quantity and quality of saliva are important to determine why some teeth are more prone than others. For example, some teeth may have holes, small cracks or fissures that allow infiltration of acids and bacteria more easily. In some cases, the structure of the jaw or teeth cleaning makes your teeth or flossing more difficult. The quantity and quality of saliva determines the rate of remineralization of teeth. For example, are usually found relatively few cavities in the lower front of the mouth where the teeth are more exposed to saliva. The type and amount of bacteria that create cavities in the mouth are also relevant. All bacteria can turn carbohydrates into acids, but some families of bacteria such as Streptococci and Lactobacilli produce acids in greater quantities. The presence of such bacteria in the plaque increases the risk of decay. Some people have higher levels of bacteria that cause cavities than others due to improper or inadequate oral hygiene.

2.Oral hygiene and fluoride use

In recent years there has been a reduction in the incidence of caries in most European countries. An increase in oral hygiene, including daily brushing and flossing to remove plaque and the use of fluoridated toothpaste, combined with regular dental examinations, seems to be responsible for the improvement. Fluoride inhibits demineralisation, encourages remineralisation and increases the hardness of tooth enamel, making it less soluble acids. A proper amount of fluoride helps prevent and control tooth decay. Fluoride can be supplied in a systematic manner through fluoridated public drinking water, other beverages and fluoride supplements. You can also provide topically, directly on the surface of the teeth through toothpaste, mouthwashes, gels and glazes. In some countries, salt, milk or other beverages have fluoride added and also have fluoride supplements in tablet or liquid. It must take into account the level of fluoride in drinking water and food when assessing the need for fluoride supplements. This is especially important in children under 6 whose teeth are still developing. Excessive consumption of fluoride can cause mottling of teeth, which is known as “fluorosis”. Brush use toothpaste with fluoride appears to be the most important factor in the decline of caries observed in many countries. Brushing and flossing help concomitantly to the fluoride application to remove bacteria from the mouth and reduce the risk of caries and periodontal disease.

The regular application of fluoride enamels made by dentists is a measure to prevent tooth decay established in many countries. This practice is especially recommended for children at high risk of decay.

The regular dental checkups can help detect and monitor potential problems. Check and remove plaque regularly can help lower the incidence of caries. If there is little plate, the amount of acid formed is insignificant and does not produce the cavities. (more…)

Dental Erosion and Caries

Dental Erosion and Caries

Dental erosion is an injury caused by the acids in the diet that causes irreversible loss of tooth tissue. At present this injury has increased by changes in diet and increased consumption of juices and soft drinks. The citric acid, phosphoric, maleic, and other content in frequently consumed beverages are responsible for this injury can be particularly destructive in children if ingested in juice bottle, for extended periods and near the hour of sleep.

According to scientific evidence, how often you eat can be critical in the process of erosion. At bedtime, a bottle should
contain only water. Remember that to prevent tooth erosion, juices and soft drinks should not be administered frequently. Preferably drink them with meals.

Prevention is implementing a set of knowledge, actions and attitudes as early as possible.

Dental caries is a controllable disease. To achieve control we need to consider the following preventive measures: oral hygiene to disrupt the bacteria and food stuck to the teeth, streamline intake of carbohydrates from which microbes produce acids that demineralizating tooth; use fluoride pasta and topics to increase tooth resistance to the action of acids and monitored periodically according to risk.
