The filling is to help control the condition without making it worse so that the dental problem does not worsen further. The filling has the effect of avoiding further deterioration of the tooth defect. Of course, you need to protect your teeth in order to avoid this situation. The filling is done because there is something wrong with the tooth, and this is the time when the damaged tissue needs to be removed so that the situation does not deteriorate further. The life of the tooth is prolonged by filling it with some replacement substance so that the inflammation of the tooth does not infest the patient anymore and so that the extraction of the tooth can be avoided. If the tooth is not protected after the filling, the situation will deteriorate and the tooth will become worse and worse, and eventually the tooth can only be extracted to solve the problem, and only in this case the tooth will rot after the filling. A filling is not a once-and-for-all solution. If you do not pay attention to the cleaning and hygiene of your teeth, your teeth will still have problems even after the filling. After the filling, you should follow the doctor’s instructions, pay attention to the cleanliness of your teeth, do not touch some hard food, and insist on rinsing your mouth with light salt water so that the filling will not cause tooth problems again. The filling will not make the tooth more and more rotten, so the patient can be assured of the treatment. Some people do need repeated fillings and need good oral hygiene and proper treatment.
