Tooth decay, also known as dental caries, is a common oral disease. It is mainly due to the decomposition of food residues by bacteria in the oral cavity, producing acidic substances that gradually corrode teeth and cause damage to the hard tissues of teeth. Over time, the decay of teeth will gradually deepen, ultimately leading to the loss of teeth. The occurrence of tooth decay is related to multiple factors. The most important of these is oral hygiene. If oral hygiene cannot be maintained, food residues and bacteria can accumulate on the surface of teeth, leading to the occurrence of tooth decay. In addition, dietary habits and immune system status may also affect the occurrence of tooth decay. The harm of tooth decay is significant. Firstly, it can have a serious impact on oral health, leading to the loss of teeth and a decline in chewing function. Secondly, tooth decay can also affect overall health. If one cannot chew food properly, it may affect the function of the digestive system. In addition, tooth decay can also affect aesthetics, and for children, it may affect their confidence and self-esteem.
1、 Prevention and control of tooth decay in high-risk populations
1. Oral health care for children
Children are a high-risk population for tooth decay. This is because children often enjoy eating sweets and candies, and their teeth and oral structure also make it easier for bacteria to grow on their teeth. To prevent tooth decay, parents should encourage their children to develop good oral hygiene habits and brush their teeth every day. Meanwhile, parents should also regularly take their children to the dentist for oral examinations and preventive treatment.
2. Oral hygiene of pregnant women
During pregnancy, hormone levels may change, which can lead to dilation, bending, and reduced elasticity of gingival capillaries, reducing the gum's tolerance to external stimuli and making it more prone to tooth decay.
Secondly, during pregnancy, pregnant women will distribute most of the calcium in their bodies to the fetus for the health of the fetus, resulting in varying degrees of calcium deficiency in pregnant women. Calcium deficiency may lead to problems such as loose teeth and toothache. The Chinese Nutrition Society recommends a daily intake of 800mg of elemental calcium for pregnant women in early pregnancy, 1000mg in mid pregnancy, and 1200mg in late pregnancy. Most pregnant women need to supplement at least 600mg of elemental calcium per day.
In addition, changes in dietary preferences may also affect the incidence of tooth decay in pregnant women. Many pregnant women may prefer sweet or heavy flavored foods during pregnancy, and these food residues in the mouth may lead to dental caries.
Therefore, in order to reduce the occurrence of tooth decay, it is recommended that pregnant women pay attention to maintaining oral hygiene, brushing and rinsing their teeth regularly; Avoid excessive intake of sweet and heavy flavored foods; At the same time, pay attention to supplementing sufficient calcium and other nutrients to maintain physical health.
3. Oral health of the elderly
Due to the decline in physical function, the oral hygiene of the elderly is often not as good as that of young people. In addition, the secretion of saliva is reduced, and the self-cleaning ability of the oral cavity is weakened, which makes it easy for bacteria to breed in the oral cavity, leading to tooth decay. In addition, elderly people often have problems such as missing teeth and gum recession, which makes food residue easy to remain and further increases the risk of tooth decay. Therefore, elderly people should pay more attention to oral hygiene, regularly undergo oral examinations and cleaning to prevent the occurrence of tooth decay. If elderly people already suffer from tooth decay, timely treatment should be sought to prevent the condition from worsening. At the same time, family members and medical staff should also pay attention to the oral health status of the elderly and provide necessary guidance and assistance.
2、 Daily care measures
1. Maintain oral hygiene: In order to reduce the number of bacteria in the mouth, it is important to brush your teeth on time. Brush your teeth at least twice a day, with each brushing session lasting no less than two minutes. When brushing teeth, use the correct brushing method, which combines horizontal vibration and vertical brushing, to ensure that every part of the teeth is cleaned, especially the gingival sulcus and gaps where dirt and grime are easily accumulated. At the same time, develop the habit of rinsing mouth after meals to remove food residues and bacteria, and reduce the number of bacteria in the mouth.
2. Balanced diet: A balanced diet is one of the important factors in maintaining oral health. Eat more foods containing vitamin C, vitamin D, as well as minerals such as calcium and phosphorus, such as fresh fruits, vegetables, whole grains, and dairy products. These nutrients help enhance the disease resistance of teeth and promote oral health. At the same time, eat less high sugar foods such as candy and sweet drinks to reduce the acidic environment in the mouth and thus lower the risk of tooth decay.
3. Removing dental plaque: Dental plaque is one of the main causes of tooth decay. By brushing teeth and using dental floss, dental plaque can be removed, thereby eliminating the microenvironment in which tooth decay occurs. Using dental floss can remove food residue and bacteria from the gaps between teeth, reducing the formation of dental plaque. It is recommended to use dental floss daily to clean teeth and remove bacteria and food residue from between teeth.
4. Use of fluoride: Fluoride has been proven to prevent dental caries for over 100 years and has achieved good results worldwide. The use of fluoride toothpaste and mouthwash can improve the disease resistance of teeth and reduce the occurrence of tooth decay. It is recommended to use fluoride toothpaste to brush your teeth every day to increase their ability to resist diseases.
5. Regular check ups: Cavities have the characteristics of concealment and burrowing, sometimes difficult to detect in a timely manner. Therefore, at least one oral examination should be conducted annually, and regular visits to the hospital for dental cleaning should be made. Oral examination can detect early tooth decay and oral problems, and take timely measures for prevention and treatment. Through regular check ups, doctors can assess oral health status, identify potential issues, and provide timely advice and treatment.
6. Groove sealing: Groove sealing is a common method for preventing tooth decay. Applying a layer of sealant on the surface of teeth can form a protective film to prevent bacteria and food residue from entering the cavities, thereby reducing the occurrence of tooth decay. It is recommended to perform pit and fissure sealing at an appropriate age to protect teeth from tooth decay.
Overall, tooth decay is a problem that we should all be concerned about. By maintaining oral hygiene, controlling dietary habits, conducting regular oral examinations, and adopting appropriate preventive treatments, we can effectively prevent and treat tooth decay. Special populations such as children, pregnant women, and the elderly also need to pay special attention to oral health to avoid tooth decay. Finally, the advice and guidance of dentists are crucial for us to maintain oral health. Only by wholeheartedly paying attention and taking action can we protect our teeth from the threat of tooth decay and maintain our oral health.
