Cavities are a disease caused by bacterial infections of the hard tissues of the teeth, and they are infectious but not contagious. If cavities are not treated in a timely manner, the inflammation can further infect the dental nerves, causing nerve inflammation, and even lead to damage in the apical region of the tooth. Damage to the apical region of a tooth may also lead to damage in the apical region of adjacent teeth due to inflammation. This situation can spread to other teeth, but it is limited to the stage of apical inflammation. If it is just a simple cavity, where decay is confined to the crown area of a tooth, it will not spread to other teeth. Therefore, once a tooth decays, it is necessary to carry out dental filling treatment as soon as possible.

Cavities that do not hurt still require root canal treatment.

Cavities that do not hurt may or may not require root canal treatment, depending on the extent of the decay. If the cavity has not reached the dental nerves, there will not be noticeable pain. In such cases, since the decay is relatively superficial, direct filling, or dental restoration can be performed without the need for root canal treatment. If the cavity is severe and has reached the dental nerves, causing the nerves to become necrotic and purulent, there will be no pain due to the loss of sensory function from nerve death. In these situations, root canal treatment is needed. This involves removing the infected dental nerves, followed by medicinal treatment of the root canal, and after the inflammation is controlled, filling of the root canal is performed. In other words, a painless cavity might actually be caused by necrosis and pus formation in the dental nerves, requiring root canal treatment.

Can you get your teeth cleaned if you have cavities?

Cavities can also be treated with teeth cleaning. Firstly, a cavity is a type of dental caries, a tooth condition caused by tissue infection. Generally, it is accompanied by pain. Teeth cleaning is needed when there is a significant build-up of tartar around the teeth, which if not promptly cleaned, can lead to gingivitis and even periodontitis, potentially causing tooth loss. During cavities, teeth cleaning can be performed. However, teeth cleaning involves ultrasonic removal of tartar around the teeth. If the cavities are deep, the cleaning process may cause discomfort or severe pain. Therefore, it is necessary to treat the cavities first before proceeding with teeth cleaning to avoid significant pain during the cleaning process.

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.

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.
