Mild pain after filling a cavity is normal. This is often seen when glass ionomer materials are used for fillings. Glass ionomer materials expand in volume within 24 hours of mixing, which can stimulate the dental nerves and cause pain. However, the pain should gradually decrease or disappear after 24 hours. If there is severe pain after the filling, it may be due to the filling material being too high or the tooth decay being too deep, reaching the dental nerves and causing nerve pain. This situation is abnormal and requires root canal treatment.

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.

Does tooth decay easily cause bad breath?

Cavities can easily cause bad breath. If there are cavities, food will remain in the holes of the cavities, get stuck, and ultimately compress the gums, and it will be difficult to clean. Foods are prone to ferment and produce acids causing bad odors, and the gums can also become inflamed, and even suppurate, which also produces bad smells. Therefore, if you have cavities, you should go to a regular hospital's dental department and receive targeted treatment under the guidance of a dentist. It is essential to develop good oral hygiene habits, brush your teeth in the morning and evening using the internationally recognized Bass brushing technique, rinse your mouth after meals, learn to use dental floss to remove food residues in tooth gaps, and treat cavities promptly to prevent them from deepening and causing more severe consequences.

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.

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.

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.
