When a patient has dental caries, if they insist on not undergoing root canal treatment, it may lead to the exacerbation of tooth decay, damage to the tooth root or gum tissue, and long-term stimulation can cause the gums to shrink, and even lead to tooth loosening and loss.

Therefore, it is recommended that if a patient has dental caries, the best method is to perform some filling restorative treatments. If the decay reaches the nerve of the teeth, it can cause symptoms of nighttime pain, or biting pain, so it is advised that the patient should undergo root canal treatment. Once tooth decay occurs, if it cannot be treated with self-repair, it is not possible to completely heal itself, and this will lead to further development.

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.

Can a cavity that exposes the dental pulp be filled?

Cavities that expose the dental pulp cannot be directly filled in one session. Treatment of the tooth must be carried out before filling. In the early stages of a cavity, only the hard tissue of the tooth is damaged. If the decayed part is removed promptly and the dental nerve is not exposed, the tooth can be directly filled in one session. However, if the cavity progresses to the point where the dental pulp, or nerve, is exposed, this requires a nerve removal procedure. After the nerve is killed, the root canal is sealed with medication, and following inflammation control, the root canal is filled. Only after root canal treatment can the tooth be filled. Otherwise, the inflammation may further develop into apical inflammation, or even lead to space infections causing facial swelling.

The concept of dental caries

Cavities, also known as dental caries or tooth decay, are caused by bacterial infection that damages the hard tissues of the teeth. Once cavities occur, it is essential to intervene with dental treatment as soon as possible. Strictly speaking, cavities represent a bacterial infection caused by the failure to remove food residues timely after eating. Bacteria break down glucose, producing lactic acid, which causes demineralization of the teeth. Once cavities occur, it is crucial to undergo dental filling treatment promptly, commonly referred to as dental restoration. If the progression of decay is not promptly halted, it can lead to further complications over time, including pulpitis which causes toothache or night pain, pain during sleep intense enough to wake one from sleep, and in severe cases, facial swelling.

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.
