Cavities can have a certain impact on tooth replacement. Cavities are a chronic progressive destructive disease caused by bacterial infection of the hard tissue of the tooth. If not treated in time, it may further develop, forming pulpitis or even apical periodontitis. Once it reaches the stage of apical periodontitis, it may form a gum abscess, or even swelling. During the process of new teeth eruption, they emerge outward through the position of the old tooth roots by absorbing the roots of the old teeth. If there is severe inflammation in the eruption pathway, it may lead to the destruction of the dental follicle of the new tooth, causing a developmental defect in the enamel of the new tooth. Therefore, it is possible that cavities can affect tooth replacement.

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.

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.

Can cavities be seen with the naked eye?

Some cavities are visible to the naked eye, while others are not. Clinically, some cavities can be observed with the naked eye. Such cavities usually have damage that extends beyond the enamel, with obvious cavities and incomplete tooth structures visible. For example, cavities on the biting surfaces of molar teeth and on the adjacent surfaces of front teeth that are moderate to severe can be seen with the naked eye. However, not all cavities can be observed with the naked eye. When the decay is confined within the enamel without obvious cavity formation, it cannot be seen with the naked eye, but it can be diagnosed by taking dental X-rays. Clinically, there are also some cavities on adjacent surfaces where the decay starts from hidden parts of the tooth; some of these might show ink-soaked-like dark brown discoloration on the biting surfaces, but they too require dental X-rays for diagnosis.

How to perform pulp drainage for dental caries?

Pulpotomy and drainage for caries involve a treatment method for acute pulpitis or apical periodontitis caused by infected dental nerves. Teeth are composed of enamel, dentin, cementum, and pulp tissue. The pulp tissue, also known as the dental nerve, is located within the innermost part of the tooth, surrounded by the hard layers of dentin and cementum. Therefore, once the dental nerve becomes inflamed, the pressure within the pulp chamber rapidly increases. To alleviate the pain, it is necessary to release this pressure, namely by performing a pulpotomy and drainage. This can be done by drilling to remove some of the infected dental tissues, and then opening up the pulp chamber to relieve the pressure, significantly reducing the pain. If the dental nerve is completely purulent and necrotic, the top of the pulp chamber can be removed, followed by thorough pulpotomy and drainage.

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.
