When patients develop dental caries, it is recommended that they visit a formal medical institution for treatment. If the tooth decay is not addressed, it may worsen significantly. While it may not always cause pain, the teeth can still be damaged. Over time, the teeth might deteriorate severely, potentially leaving only the roots. This could also lead to damage to the tooth roots, causing inconvenience in the patient's dietary life and might lead to severe complications later on, including pain and irritation to the gum tissue. Therefore, it is advised that patients seek early medical treatment and undergo appropriate therapeutic measures based on the condition of their dental caries.

How to treat children with dental caries?

To treat cavities in children, first, the extent of tooth decay needs to be assessed. If the decay is mild, the decayed part can be removed and directly filled. If the decay is severe enough to inflame the dental nerve, an X-ray of the tooth is required. If it is a deciduous tooth that is about to fall out soon and is not worth saving, treatment might be unnecessary. However, if the tooth root has not been absorbed and the permanent tooth will take a long time to erupt, root canal treatment can be considered. In cases where a young permanent molar is decayed and the nerve is infected, a vital pulpotomy should be performed to preserve the living pulp and promote further development of the tooth root.

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.

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.

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 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.
