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.

How to prevent cavities in children

Prevention of tooth decay in children should first encourage them to develop good tooth-brushing habits, reducing bacteria and plaque on the tooth surface, and include brushing in the morning and evening, as well as rinsing after meals. Enamel is the hardest substance in the human body but is susceptible to cracking. Acidic or sugary substances are harmful to teeth, so it's best to avoid sweets and acidic foods in the evening and to brush teeth before going to bed. Brushing teeth before sleeping is crucial and some anti-cavity treatments should be done, such as fluoride application or dental sealants. It's also important to develop a habit of regular dental check-ups to detect and treat cavities early.

If a cavity is not thoroughly cleaned before being filled, what will happen?

When a patient has severe dental caries and undergoes filling, if the decay is not completely removed before filling, it may lead to reinfection and residual decay, continuing to cause inflammation. Therefore, it is recommended that the decay be completely removed before filling. In such cases, it is generally safe for patients to seek treatment at a formal dental hospital. Official hospitals adhere to strict standards, effectively cleaning the affected area for filling and repair. Therefore, patients need not be overly anxious; this type of procedure is quite common in dentistry. Patients are advised to maintain good oral hygiene in daily life and seek timely medical attention when dental caries occur.

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.

How to treat a tooth that is half decayed?

When a patient has a cavity that has already damaged the dental tissues, causing severe damage to the dental tissues, the general advice for the patient is to go directly to a regular dental hospital for treatment. The best approach is generally to extract the tooth; extraction is the best option, but it should be done when the body is in good condition to remove the damaged tooth. Additionally, patients should pay attention to oral hygiene and can take some anti-inflammatory drugs orally to effectively control inflammation. Furthermore, during tooth extraction, it is crucial to pay attention to local hygiene, be mindful of food residue inside the mouth, eat and drink before the extraction, keep a relaxed mood, and follow the doctor's advice after extraction. Generally, do not eat for two hours after the surgery, do not brush your teeth or rinse your mouth within a day, avoid touching the wound, and manage your diet reasonably.

Does tooth decay easily cause bad breath?

Cavities can easily cause bad breath. If there are cavities, food will remain in the holes of the cavities, get stuck, and ultimately compress the gums, and it will be difficult to clean. Foods are prone to ferment and produce acids causing bad odors, and the gums can also become inflamed, and even suppurate, which also produces bad smells. Therefore, if you have cavities, you should go to a regular hospital's dental department and receive targeted treatment under the guidance of a dentist. It is essential to develop good oral hygiene habits, brush your teeth in the morning and evening using the internationally recognized Bass brushing technique, rinse your mouth after meals, learn to use dental floss to remove food residues in tooth gaps, and treat cavities promptly to prevent them from deepening and causing more severe consequences.
