The following factors have an important effect on dental health:
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…)
