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.
Can tooth decay pain be relieved with Sichuan pepper?
If a patient has dental caries and is experiencing considerable pain, and there are no medications available nearby, they can temporarily use Sichuan peppercorns for pain relief. This is because certain components within Sichuan peppercorns can alleviate some of the pain, although they do not treat the dental caries directly. Thus, it is recommended that if a patient is suffering from toothache due to dental caries, they should seek timely treatment at a hospital. The specific treatment plan should be based on the extent of damage caused by the dental caries. If the damage is minor, the tooth generally does not require special treatment; however, if the dental caries are severe and have damaged the tooth structure, root, or even the dental nerves or gum tissue, it is advisable for the patient to consider tooth extraction followed by a dental restoration. The specific recommendations should still be based on a doctor’s diagnosis and a tailored treatment plan should be established.
Can tooth decay be cured?
Cavities are a type of destructive dental hard tissue disease caused by bacterial infections and are also a chronic progressive infectious disease. Cavities can only improve through early and effective intervention and treatment; otherwise, the condition may develop further, leading to pulpitis or apical periodontitis. Severe cases can also cause systemic symptoms such as space infections, and some may lead to bacteremia or sepsis. In the early stages of development, cavities have no clinical symptoms. At this stage, filling the cavity is painless. If the decay progresses to reach or approach the dental nerve, filling the cavity can then cause widespread pain. If it reaches the dental nerve, it cannot be directly filled in one go; it requires dental treatment for improvement.
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.
How long does it generally take for the pain from a cavity to ease when biting?
When patients experience some occlusal pain due to tooth decay, the time it takes for relief depends on the patient's inflammation levels and the treatment measures taken. If the patient receives timely treatment and effectively alleviates the inflammation, it generally takes about a week to heal and relieve the pain. If the patient does not undergo treatment, the condition may worsen and the pain may persist longer. Therefore, when a patient has tooth decay, it is best to visit a hospital for a consultation. Treatment should be administered based on the extent of the decayed tooth, and in severe cases of decay, tooth extraction might be necessary.
Can cavities be detected in an X-ray?
In clinical practice, not all cavities require X-rays, nor can all cavities be detected through X-rays. The purpose of taking X-rays is to understand the depth of the cavity and the distance between the cavity and the dental nerve. Some cavities occur on the surfaces between teeth which cannot be seen with the naked eye; in these cases, X-rays can provide a clear diagnosis. However, early-stage cavities only involve changes in the enamel, showing as chalky changes or small black dots and lines on the tooth surface. For these superficial changes, X-rays will not show any abnormalities. Therefore, it is important to maintain oral hygiene by brushing teeth morning and evening, and rinsing after meals to detect and treat cavities early, to prevent other complications.
Will children's cavities grow new teeth?
Children's cavities can also regrow new teeth. Cavities, also known as dental caries, refer to the destruction of hard dental tissues under a bacterial infection. It is crucial to treat children's cavities early, otherwise, they may affect the underlying new teeth. If the cavity reaches the level of periapical inflammation, meaning the dental pulp tissues become pus-filled or necrotic, and gum abscesses appear, it could cause the newly emerged teeth to develop caries. Sometimes, it may also lead to abnormal eruption pathways of the new teeth, such as abnormal eruptions on the lip side or cheek side, resulting in misaligned teeth, which can impact the arrangement of the child’s primary or permanent teeth.
Can tooth decay heal by itself?
Cavities are a type of dental hard tissue defect caused by bacterial infection, and represent a chronic, progressive, destructive disease. In the early stages of a cavity, if only the enamel layer is involved with simple demineralization of the tooth, then remineralization treatment can be conducted. This scenario is the only reversible one where the cavity can heal itself. If the cavity progresses to the dentin layer, then it cannot heal by itself and requires timely intervention by drilling to remove the decayed part and performing a filling treatment. If the infection is not controlled in time, bacteria can further cause the dental nerve to become purulent and necrotic, leading to symptoms of pulpitis or apical periodontitis. In such cases, timely root canal treatment is necessary.
Why do cavities turn black?
Cavities generally appear black, while normal teeth are white. The structural changes in the dental tissues due to bacterial infection cause the hard tissues of the teeth to demineralize, enlarging the internal spaces of the teeth. This can cause cavities to appear black under the refraction of sunlight, resulting in a black appearance. Additionally, after the deterioration of the tooth due to decay, the breakdown of the hard tissue allows food residues or plaque to enter the cavities, which can also cause the cavities to turn black. This situation requires early dental filling to remove the decayed parts, followed by root canal treatment, otherwise it can lead to pulpitis, causing tooth pain.
What will happen if you insist on not getting a root canal for a cavity?
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.
