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.
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.
