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.

Will tooth decay affect other teeth?

When a patient suffers from tooth decay, generally not taking measures to treat it may cause other teeth to also develop cavities. Some patients with long-term cavities may have one or more teeth affected, and even some patients might have entire teeth significantly decayed. Therefore, when cavities occur, certain measures must be taken for treatment. Depending on the condition of the cavity, a specific treatment plan should be formulated, whether it's a dental filling or tooth extraction. Thus, patients must pay attention to oral hygiene in their daily lives, brushing their teeth morning and evening. After meals, it's important to promptly remove food residues from the mouth and develop proper habits for brushing and eating. If a cavity develops, the patient should treat it early to prevent it from affecting other teeth.

What will happen if tooth decay is not treated?

If dental caries are not treated, they may further infect and cause inflammation of the dental nerves, leading to pulpitis or apical periodontitis, causing severe pain. When apical periodontitis occurs, it may sometimes lead to a space infection, which is facial swelling. If the inflammation is not controlled in time, it may also cause osteomyelitis of the jawbone. Therefore, dental caries need to be treated as early as possible. Dental caries are caused by bacterial infections that lead to the decay of the hard tissues of the teeth; in the early stages of decay, using a drill to stop the development of the disease—namely, timely filling—can effectively control the further progression of dental caries. If dental caries further infect and cause inflammation of the dental nerves, it can lead to pain while eating or sleeping, sometimes waking from sleep due to pain, and in severe cases, it can cause facial swelling.

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.

Can cavities be seen with the naked eye?

Some cavities are visible to the naked eye, while others are not. Clinically, some cavities can be observed with the naked eye. Such cavities usually have damage that extends beyond the enamel, with obvious cavities and incomplete tooth structures visible. For example, cavities on the biting surfaces of molar teeth and on the adjacent surfaces of front teeth that are moderate to severe can be seen with the naked eye. However, not all cavities can be observed with the naked eye. When the decay is confined within the enamel without obvious cavity formation, it cannot be seen with the naked eye, but it can be diagnosed by taking dental X-rays. Clinically, there are also some cavities on adjacent surfaces where the decay starts from hidden parts of the tooth; some of these might show ink-soaked-like dark brown discoloration on the biting surfaces, but they too require dental X-rays for diagnosis.

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.
