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.

What to do if you have tooth decay and swollen, painful gums?

When patients experience dental caries and swollen, painful gums, it is advised that they seek medical attention promptly. They may take some anti-inflammatory and analgesic medications to relieve inflammation and pain. After the inflammation has completely subsided, treatment should be based on the extent of damage to the dental caries. If the damage to the dental caries is minor, conservative treatment may be sufficient. However, if the damage is severe, it may affect part of the tooth structure or even the entire tooth and root, possibly leading to cavitation. In such cases, it is recommended that patients consider tooth extraction or filling as remedial measures. Additionally, patients must pay attention to oral hygiene and develop correct tooth brushing habits. (The use of medications should be under the guidance of a professional doctor.)

How to treat tooth decay without a cavity?

Once a cavity forms, there is definitely a cavity hole. It might appear that there is no hole on the surface, but the texture has already softened, forming a cavity hole; it's just that it has not been discovered by oneself. It can be seen by a doctor using an examination and can also be detected by taking dental X-rays. At this point, one should follow the treatment principles for cavities, which involve removing the decayed and necrotic material inside the cavity and then filling it with filling material. If it is an interproximal cavity, the decay inside can be removed via an X-ray and then filled. Some occlusal pit and fissure caries, which are relatively shallow, can be treated with topical fluoride medication. For cavities, it is important to detect and treat them early. Regular oral hygiene should be maintained, with brushing in the morning and evening, and rinsing after meals. If a cavity is not treated in time, it will become deeper and ultimately turn into a residual root, which will need to be extracted.

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.

Do children's cavities need treatment?

Whether children's dental caries need treatment may require taking X-rays of the teeth, or it can be judged based on the child's age. If a child around seven or eight years old has decay in the front teeth, these teeth can soon be replaced, and treatment may not be necessary. However, if the molars at the back, which are replaced at around twelve or thirteen years of age, are decayed, then it is necessary to treat these early by removing the decay and filling the teeth. Otherwise, bacteria may further infect the dental nerves, causing pain. If children's dental caries are not timely treated, it can also affect chewing. During childhood, the jawbone undergoes significant development. If the chewing function is impaired, it can affect the development of the jawbone, hence early treatment of children's dental caries is essential.

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.
