When patients experience dental caries and swollen, painful gums, it is advised that they seek medical attention promptly. They may take some anti-inflammatory and analgesic medications to relieve inflammation and pain. After the inflammation has completely subsided, treatment should be based on the extent of damage to the dental caries. If the damage to the dental caries is minor, conservative treatment may be sufficient. However, if the damage is severe, it may affect part of the tooth structure or even the entire tooth and root, possibly leading to cavitation. In such cases, it is recommended that patients consider tooth extraction or filling as remedial measures. Additionally, patients must pay attention to oral hygiene and develop correct tooth brushing habits. (The use of medications should be under the guidance of a professional doctor.)

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.

What should I do about bad breath caused by dental caries?

If a patient is suffering from dental caries that have already caused bad breath, the situation requires active treatment targeting the dental caries. Due to the ease with which food residue and bacteria can accumulate in cavities, this will cause an odor in the mouth. Initially, it is essential to clear out food debris, bacteria, and any decayed material from the cavity. If the cavity is shallow, it can be directly filled with light-cured resin material. After the cavity is filled, the patient's bad breath symptoms should be alleviated. However, if the cavity is deep, it should first be treated with a pulp-protecting base before filling. If the dental nerve is affected, causing pulpitis, root canal treatment must be conducted first.

Should a baby's decayed front teeth be filled?

Children's front teeth cavities require filling treatment, because if the front teeth are extensively damaged, it not only affects eating and appearance but also impacts the child's psychological development. Therefore, if a child's tooth color is abnormal, it is advisable to visit a hospital for fluoride treatment as soon as possible, which is beneficial for mineralization on the tooth surface. However, if cavities have developed in the front teeth, filling treatment is needed, otherwise it will progressively worsen, affecting the child's normal eating habits. Generally, children under three years of age have poor cooperation and cannot undergo routine outpatient treatment, so it is crucial to strengthen oral hygiene care in daily life.

Can cavities be transmitted to other people?

Cavities are not contagious to other people. Cavities themselves are not considered a contagious disease. The development of this condition is a long-term and complex process, not merely caused by the transmission of pathogens. Initially, there are some pits and fissures on a patient's teeth which are easily attacked by acidic substances produced by bacteria, leading to the demineralization of calcium in the enamel, thereby softening and collapsing the enamel. If a patient frequently consumes sweet foods and neglects oral hygiene, not brushing or rinsing thoroughly, it could lead to bacteria decomposing these sweet food residues, continually damaging the patient’s teeth and resulting in cavities.

Why do cavities turn black?

Cavities generally appear black, while normal teeth are white. The structural changes in the dental tissues due to bacterial infection cause the hard tissues of the teeth to demineralize, enlarging the internal spaces of the teeth. This can cause cavities to appear black under the refraction of sunlight, resulting in a black appearance. Additionally, after the deterioration of the tooth due to decay, the breakdown of the hard tissue allows food residues or plaque to enter the cavities, which can also cause the cavities to turn black. This situation requires early dental filling to remove the decayed parts, followed by root canal treatment, otherwise it can lead to pulpitis, causing tooth pain.
