Dental caries
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.
Can cavities spread to other teeth?
Cavities are a disease caused by bacterial infections of the hard tissues of the teeth, and they are infectious but not contagious. If cavities are not treated in a timely manner, the inflammation can further infect the dental nerves, causing nerve inflammation, and even lead to damage in the apical region of the tooth. Damage to the apical region of a tooth may also lead to damage in the apical region of adjacent teeth due to inflammation. This situation can spread to other teeth, but it is limited to the stage of apical inflammation. If it is just a simple cavity, where decay is confined to the crown area of a tooth, it will not spread to other teeth. Therefore, once a tooth decays, it is necessary to carry out dental filling treatment as soon as possible.
Will tooth decay recur after a filling?
Cavities are a type of chronic, progressive destructive disease caused by bacterial infection of the hard tissues of the teeth. Normally, a cavity should not recur after being filled, but each dental filling material has a certain degree of microleakage. If glass ionomer materials are used, the microleakage is somewhat larger, and after filling, there might be tiny gaps between the edge of the filling material and the tooth, where bacteria can continue to infect, also known as secondary caries, necessitating timely refilling of the tooth. If resin-based materials are used, the microleakage is relatively smaller, and the likelihood of recurrence after the filling is smaller.
How to treat a cavity that has decayed to the root of the tooth?
For a tooth decayed to the root, it is first necessary to take an X-ray of the tooth. If the X-ray shows that the root still has some salvage value, the tooth can be preserved through root canal treatment after controlling the inflammation. If the decay has reached the tip of the root and the root has no salvage value, the tooth needs to be extracted soon after controlling the inflammation. After the tooth is extracted, it is necessary to get a dental prosthesis as soon as possible depending on the condition of the tooth. If the prosthesis is not done in time, the tooth above may elongate, and the teeth on either side may tilt towards the gap, potentially leading to the loss of space over time.
