Dental caries
The causes of dental caries formation
The causes of dental caries include bacterial factors, dietary factors, the tooth's own factors, and time factors, also known as the four-factor theory of dental caries. Dental caries initially result from bacterial infection. Under such infections, the hard tissues of the tooth undergo a chronic destructive deterioration; over time, this results in cavity formation. That is to say, the formation of dental caries primarily occurs under bacterial infection. Additionally, diet is a main cause of dental caries, especially sugary foods. Bacteria use glucose to produce acid, leading to tooth demineralization and cavity formation. Moreover, congenital calcium deficiency in teeth, leading to incomplete enamel development, is also an important cause of dental caries. Furthermore, the formation of dental caries requires a certain time factor.
Can a cavity wait a month?
Cavities should be filled as soon as possible, through a treatment known as filling, and it is best not to delay. If a cavity could have been simply filled within a month, it might further become infected, causing inflammation of the dental nerve and leading to conditions such as pulpitis or apical periodontitis. Direct filling won't be possible; the tooth will need treatment before it can be filled. Cavities are a type of hard tissue decay caused by bacterial infection. If it's an adult's cavity, the progression is relatively slow and may only advance partially within a month, not reaching the dental nerve. However, in children, cavity progression is very rapid; if not promptly treated, severe dental nerve pain could occur within a month, necessitating further dental treatments.
Can a decayed tooth be extracted?
Whether a tooth with caries can be extracted depends on the extent of the decay. If the decay is shallow, it can be treated with a one-time filling. If the decay is deep, reaching the nerve, nerve-killing treatment is required, followed by anti-inflammation measures and, after inflammation control, root canal filling. In other words, teeth should be preserved through root canal treatment whenever possible and not extracted. If the caries has reached the deep layers of the tooth dentin, or is at risk of causing a perforation, such conditions are considered non-salvageable and the tooth should be promptly extracted. After extraction, timely dental prosthetics should be placed.
Permanent tooth decay
Permanent tooth decay refers to the decay occurring in newly erupted teeth. The most common case is the first permanent molar, also known as the six-year molar, which emerges quietly in the mouth at the age of six. Once this tooth emerges, it cannot be replaced for life. If this tooth decays, it is necessary to fill the tooth as soon as possible; otherwise, if the decay reaches the dental nerve, it could lead to pulpitis. Alternatively, for newly erupted teeth, sealants should be applied to the pits and fissures of the teeth to slow down the pace of decay. Permanent tooth decay requires us to intervene with treatment as early as possible; otherwise, it may cause pain or even tooth loss.
How to prevent dental caries
Cavities are a destructive disease caused by bacterial infection of the hard tissues of the teeth. The first step in preventing cavities is to understand the causes and implement basic prevention measures. Firstly, the condition is associated with bacterial infection, and controlling dental plaque through effective brushing can help. Data shows that dental plaque can easily reattach to teeth within eight hours after brushing. Therefore, it is recommended to brush your teeth twice a day, in the morning and evening. Some people are accustomed to brushing at night and just rinsing in the morning; however, this practice is incorrect as effective brushing helps control the accumulation of dental plaque. Secondly, diet plays a role, with sugary foods, especially sucrose, being particularly conducive to cavities. It is advisable to reduce the intake and frequency of sugar consumption. Additionally, effectively supplementing calcium can help prevent inherent enamel hypoplasia of the teeth. If the mother experiences calcium deficiency during pregnancy, there is also a higher risk of cavities.
Is a cavity the same as tooth decay?
Cavities, also known as dental caries, are a chronic progressive destructive disease caused by bacterial infection of the hard tissues of the teeth. Once a tooth is affected by a cavity, it is necessary to fill the tooth as soon as possible. Otherwise, the bacteria will further infect the tooth, causing inflammation of the dental nerve. Inflammation results in significant pain, including sensitivity to hot and cold, pain intensified by temperature changes, and even symptoms of nighttime pain. The most typical symptom of pulpitis is nighttime pain, which can wake someone from sleep. Therefore, once cavities occur, it is crucial to remove the decayed part of the tooth and fill it promptly to prevent potential tooth loss.
Can cavities be brushed with an electric toothbrush?
Cavities can be cleaned using an electric toothbrush. However, if the cavity is severe, the vibrations from the electric toothbrush may cause pain. It is necessary to fill or treat teeth with cavities as soon as possible. Only after treatment can the progression of the cavity be controlled; merely brushing with an electric toothbrush cannot control the development of the cavity. Cavities are a destructive disease caused by bacterial infection of the hard tissues of the teeth. Control over cavities can only be achieved by removing decay and using a drill to remove the infected cavity tissue; an electric toothbrush cannot control the development of cavities.
How to perform pulp drainage for dental caries?
Pulpotomy and drainage for caries involve a treatment method for acute pulpitis or apical periodontitis caused by infected dental nerves. Teeth are composed of enamel, dentin, cementum, and pulp tissue. The pulp tissue, also known as the dental nerve, is located within the innermost part of the tooth, surrounded by the hard layers of dentin and cementum. Therefore, once the dental nerve becomes inflamed, the pressure within the pulp chamber rapidly increases. To alleviate the pain, it is necessary to release this pressure, namely by performing a pulpotomy and drainage. This can be done by drilling to remove some of the infected dental tissues, and then opening up the pulp chamber to relieve the pressure, significantly reducing the pain. If the dental nerve is completely purulent and necrotic, the top of the pulp chamber can be removed, followed by thorough pulpotomy and drainage.
Can a cavity that exposes the dental pulp be filled?
Cavities that expose the dental pulp cannot be directly filled in one session. Treatment of the tooth must be carried out before filling. In the early stages of a cavity, only the hard tissue of the tooth is damaged. If the decayed part is removed promptly and the dental nerve is not exposed, the tooth can be directly filled in one session. However, if the cavity progresses to the point where the dental pulp, or nerve, is exposed, this requires a nerve removal procedure. After the nerve is killed, the root canal is sealed with medication, and following inflammation control, the root canal is filled. Only after root canal treatment can the tooth be filled. Otherwise, the inflammation may further develop into apical inflammation, or even lead to space infections causing facial swelling.
Do cavities have worms in them?
Cavities do not contain worms; they are caused by bacterial infections and are a type of infectious disease. Cavities are also known as dental caries, and many people mistakenly believe they are caused by worms chewing on the teeth, but this is not the case. Cavities occur when bacterial infections attack the hard tissues of the teeth, leading to destructive dental diseases. It is also a chronic infectious disease. Cavities are caused by bacterial factors, meaning bacteria are the initial factor in their development. Bacteria can use glucose to produce lactic acid, causing demineralization of the teeth and thus forming cavities. If one brushes their teeth and rinses their mouth immediately after eating to control dental plaque, the development of cavities can be controlled or slowed. If not controlled in time, cavities may further lead to pulpitis.
