How to deal with loosening of the front teeth due to periodontitis?
For periodontitis with loosening of the front teeth, an X-ray of the teeth is needed to assess the severity of the periodontitis. If the loosening of the front teeth is simply due to absorption of the alveolar bone, this can be addressed through basic periodontal treatment, which includes teeth cleaning to remove tartar, dental plaque, and other local irritants, followed by irrigation around the gums, medication application, or guided bone regeneration to improve the looseness of the teeth. However, if the periodontitis is accompanied by severe alveolar bone loss, tooth extraction may be necessary.
How many days can pulpitis be cured?
Pulpitis can only improve by undergoing dental treatment, with most cases clinically arising from the progression of dental caries. If dental caries are not promptly filled in the early stages to halt their progression, bacteria can further infect and cause nerve damage. After a nerve-killing treatment for pulpitis, pain generally subsides. The specific duration depends on the nerve-killing medication used; some act quickly, usually within 2 days or 48 hours, killing the dental nerve and thus alleviating the pain of pulpitis. Others may act slowly, requiring about 2 weeks, or approximately 14 days.
How to deal with toothache from cavities?
Cavity toothache occurs when bacteria infect the hard tissue of the tooth, approaching or reaching the dental nerve, causing a pain response from the nerve, which is also a self-protective reaction. Initial treatment for cavity toothache involves using a drill to remove the decayed hard tissue of the tooth. If the decay is completely removed and the dental nerve is not exposed, this condition can be directly treated by filling or using a pulp-capping agent to protect the nerve before filling. If, after removing the decay, the dental nerve is exposed or reached, the situation cannot be resolved with a direct and immediate filling. Instead, nerve-killing procedures are necessary, which involve root canal treatment of the tooth.
What should I do about recurrent gingivitis?
Gingivitis is caused by not cleaning the mouth promptly after eating, with the presence of irritating factors around the teeth causing repeated outbreaks. For example, bleeding during brushing or eating. This situation requires teeth cleaning, which includes ultrasonic scaling to remove dental calculus and other basic causative factors. Only by removing the irritating factors and treating the cause, applying medicine around the gums and improving the bleeding condition, can the symptoms of gingivitis improve. If oral hygiene is not maintained after removal, over time, dental calculus or dental plaque can reattach around the teeth, leading to a recurrence of gingivitis.
Does pulpitis require tooth extraction?
Pulpitis does not require tooth extraction but necessitates root canal treatment. Pulpitis is a symptom caused by deep dental decay and bacterial infection reaching the dental nerves, manifesting as pain when eating or nocturnal pain. The inflammation in pulpitis is confined within the pulp and does not affect the root apex area. This infection can be resolved through comprehensive root canal treatment. The treatment begins with nerve devitalization; after the nerve is killed, infected dental tissues are removed using a drill, extracting the purulent dental nerve. Subsequently, medication is applied in the root canal. After inflammation is controlled, the root canal is filled. After treatment, the tooth affected by pulpitis can be preserved without extraction.
Is periodontal disease the same as periodontitis?
Periodontal disease includes periodontitis, but periodontal disease covers a much broader range than periodontitis. Periodontium is the supporting tissue of the teeth, which includes the gums, alveolar bone, and dental cementum, so the scope of periodontal disease is very broad, while periodontitis is just a branch of periodontal disease. Periodontitis is caused by tartar, soft plaque, or dental plaque around the teeth, which if not promptly removed by teeth cleaning, can lead to congested gums or bleeding during brushing. Severe cases can cause absorption of the alveolar bone. Once destructive absorption of the alveolar bone occurs, teeth will become loose and may even fall out. It can also be said that periodontitis is a severe stage in the further development of periodontal disease.
Is it normal to have pain after filling a cavity?
Mild pain after filling a cavity is normal. This is often seen when glass ionomer materials are used for fillings. Glass ionomer materials expand in volume within 24 hours of mixing, which can stimulate the dental nerves and cause pain. However, the pain should gradually decrease or disappear after 24 hours. If there is severe pain after the filling, it may be due to the filling material being too high or the tooth decay being too deep, reaching the dental nerves and causing nerve pain. This situation is abnormal and requires root canal treatment.
Will tooth decay affect the replacement of teeth?
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 bleeding gums leukemia?
Gum bleeding is not necessarily leukemia; it could also be gingivitis, periodontitis, or other diseases of the hematopoietic system. Gum bleeding is a common clinical symptom of gingivitis, caused by irritants like dental plaque and tartar around the teeth, keeping the gum tissue in a congested state. If persistent, this can lead to gum bleeding. This condition can be improved by dental cleaning, followed by medicated rinses around the teeth. If the situation does not improve, it may be due to periapical abscess caused by periapical inflammation of the tooth, which can also result in gum bleeding. In this case, root canal treatment is required, and once the inflammation in the root canal is controlled, the gum bleeding may alleviate on its own. If neither of these treatments is effective, it could be due to an underlying hematopoietic system disease, which would require further examination.
Can pulpitis be detected with an X-ray?
Pulpitis is divided into normal pulpitis and retrograde pulpitis. Normal pulpitis is a further development from bacterial infection of the hard tissues of the tooth to the pulp tissues, which means it can be captured on an X-ray. It mainly presents as a low-density image near the pulp. This stage of pulpitis is normal, developed through the normal pathway, and can be identified on an X-ray. If the pulpitis is due to the development of a periodontal pocket, bacteria infect the root apex area retrogradely through the periodontal pocket, causing pathological changes in the pulp tissue of the root apex area. Retrograde pulpitis cannot be detected on an X-ray.
