1, sugar is the only culprit of dental caries? Misunderstanding, but also almost a fact. It is the acids produced by bacteria in the mouth that are the real culprits of dental caries. Any carbohydrate you eat every day such as sugar, rice, potatoes, bread, fruits and vegetables can be metabolized by bacteria, which then produce acid. 2, acid can cause tooth decay? Truth. Acids can damage the surface layer of teeth (enamel), making it weaker and more susceptible to caries. Caries-causing bacteria in the mouth metabolize acids, and if you eat acidic foods (including fruit juices and sodas) more frequently than usual, it will accelerate the development of dental caries. Therefore everyone needs to be vigilant about acidic foods in order to better maintain oral health.” 3, Children are more susceptible to caries than adults Myth. In the past 20 years, due to the application of fluoridated water sources, the incidence of dental caries in school-age children in the United States has been reduced by 50%, however, the incidence of dental caries in the middle-aged and elderly populations have a tendency to increase, which may be related to the use of certain medications that cause dry mouth. These drugs will reduce the secretion of saliva, reducing the protective effect of saliva. 4, when the appearance of dental caries, one can immediately perceive? Misconception.

Areas that are not easily cleaned with a toothbrush or floss are the places where bacteria are hosted the most, and therefore have the highest likelihood of developing caries. Proper flossing, along with the use of mouthwash, can help clean these hidden areas. 7. Teeth grinding can lead to dental caries This is not entirely true. Acid-producing bacteria are the root cause of caries. But teeth grinding can also be very damaging to your teeth. Under normal chewing conditions, the contact time between teeth is short and produces little pressure. But grinding teeth when the surface of the teeth under increased pressure, will eventually lead to cracks or broken teeth, and then will accelerate the occurrence of dental caries. 8, large gaps in the teeth are prone to caries Myth. A large gap between the teeth will make dental cleaning easy. The cleaner the bacteria are removed, the less prone to caries. Small gaps are easy to accumulate food debris, if not carefully cleaned, more prone to caries. 9. Cracks and chips in the teeth will be prone to caries Facts. Cracks and chips on the teeth are usually not easy to clean and become the best place for bacteria to hide, making them susceptible to caries over time. The use of fluoride mouthwash can help clean these hidden areas of bacteria. 10, tooth sensitivity means caries misunderstanding. It is true that caries can develop to a certain stage and produce symptoms of sensitivity to cold and sweet foods. But tooth wear, dentin exposure and other non-caries diseases can also lead to tooth sensitivity. 11. The only reason for “killing the nerve” (root canal treatment) is caries Misconception. Nerve damage in the root canal requires “nerve killing” treatment (root canal therapy). Nerve damage can be caused by dental caries, bruxism or periodontal problems. 12. Rotating aspirin next to the tooth will relieve the toothache Misconception. Oral aspirin can relieve toothache. But because aspirin is an acidic drug, placed near the teeth, not only does not stop the pain, but will burn the gum tissue causing ulcers or abscesses, so that the pain is aggravated. 13, fillings need to be replaced regularly Misunderstanding. Both resin fillings and silver mercury fillings do have a service life, but the length of time depends on the degree of tooth wear and oral hygiene. If regular oral checkups are available, the chances of problems in the mouth will be greatly reduced, and the life of the filling will be extended.” 14, the child is small is not in a hurry to brush the teeth misunderstanding From the first eruption of the child should be well cleaned, the general use of finger toothbrushes, or gauze, cotton, the surface of the teeth clean, you can achieve the role of caries prevention. 15, the child with a soft-bristled toothbrush good misunderstanding Generally speaking, to the child to choose neutral bristle toothbrush can, there is no need to use soft bristle.
