The filling treatment in the regular hospital is not harmful, and there are only benefits for the patient is no harm. In the office, I often hear some patients say that the tooth cannot be filled, and the filling will become bigger and bigger after moving. That may be because they did not receive the regular dental filling operation. As long as the professional doctor completely and thoroughly removes the insect tooth tissue in the mouth, and then carries out the filling operation step by step according to the operation specification, including acid etching, bonding, cavity preparation, etc., finally, after the filling, the patient also needs to carefully clean the oral hygiene, including correct and effective brushing, flossing and interdental brushing on the adjacent surface, etc., to ensure that there is no persistent plaque in the long crack between the filling material and the tooth body. The filling material will be firmly bonded to the tooth and will remain with the patient’s mouth for the rest of his or her life without any problems. Therefore, it is recommended that patients, if they have wormy teeth, should visit a professional dentist early to diagnose and treat the bacteria in the mouth early. Fillings can only benefit the patient without any disadvantages. There is also the operation of filling teeth, which can significantly reduce the bacterial content in the mouth. Scientific research has confirmed that the increase of bacterial content in the mouth and cardiovascular diseases such as coronary heart disease, kidney diseases, diseases of bone tissue, inflammation of the bladder system, etc. are very related. Therefore, if there are wormy teeth in the mouth, it is recommended that patients remove them early and have regular fillings, which will only benefit and not harm the oral health and general health.
