If children have dental caries, it is crucial to treat them actively, even if the caries are on primary teeth, timely repair is necessary. Once a child's teeth begin to erupt, it is important to start brushing their teeth and maintaining good oral hygiene. If caries have already developed, take the child to a pediatric dental clinic for tooth repair. This is especially true for the back molars, which, even though they may be replaced at the age of six, still need to be repaired throughout the process. Otherwise, it will affect the eruption and alignment of the permanent teeth later on. Therefore, if children develop dental caries, it is essential to visit a hospital as soon as possible for dental treatment, and once all the molars are in place, fissure sealants should be applied.

Is tooth decay a contagious disease?

Cavities occur due to a large amount of dental plaque and tartar on the teeth, which erodes the teeth over time, causing damage to the enamel and dentin. This results in the appearance of black spots, black patches, and cavities. However, cavities are not contagious because there are always a large number of bacteria in the mouth due to eating and other reasons, so it is important to develop good brushing habits and the correct technique. Although brushing can remove some dental plaque, its effect is limited. It is best to undergo dental and gum cleaning treatments to significantly improve the removal of dental plaque and eliminate the harm of cavities to the human body.

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.

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.

Can you ignore a cavity if it doesn't hurt?

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.

If the cavity doesn't hurt, does that mean it hasn't reached the nerve?

It is necessary to make judgments based on the patient's symptoms and examination results. Dental caries refers to the chronic, progressive, destructive disease occurring in the hard tissues of the teeth under the influence of various factors such as plaque bacteria. Whether dental caries is painless or has reached the nerve, the simplest clinical method is to judge based on the patient's symptoms, asking whether the patient experiences pain. In the early stages, there are only changes in the color and texture of the tooth, which do not cause pain. In the later stages of the disease, due to necrosis of the dental pulp, pain may not occur. At this time, diagnosis can be assisted by dental films; an X-ray can show the low-density shadow produced by the caries, and whether this low-density area significantly erodes into the dental pulp, which is also an auxiliary diagnostic method. Therefore, it is important to maintain oral hygiene, brush teeth morning and evening, and rinse mouth after meals.
