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.

Wisdom tooth has a cavity, should it be pulled or filled?

Whether to extract or fill a decayed wisdom tooth first depends on the condition of the wisdom tooth itself. If the wisdom tooth has erupted properly, is not impacted, and participates in occlusion and chewing food, it can be preserved and continue to function in chewing. If the eruption of the wisdom tooth has caused resorptive damage to the anterior teeth through compression, or if the wisdom tooth is impacted and recurrent pericoronitis occurs, there is no need to forcefully preserve the tooth. It can be extracted after inflammation control, and the extraction will not affect chewing functions.

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.

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.

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.

How to treat a cavity that has decayed to the root of the tooth?

For a tooth decayed to the root, it is first necessary to take an X-ray of the tooth. If the X-ray shows that the root still has some salvage value, the tooth can be preserved through root canal treatment after controlling the inflammation. If the decay has reached the tip of the root and the root has no salvage value, the tooth needs to be extracted soon after controlling the inflammation. After the tooth is extracted, it is necessary to get a dental prosthesis as soon as possible depending on the condition of the tooth. If the prosthesis is not done in time, the tooth above may elongate, and the teeth on either side may tilt towards the gap, potentially leading to the loss of space over time.
