Why Should Expired Restorations (Fillers And Crowns) Be Renewed?
There are some reasons for this;
REPEATING CARIES; Conditions that cause initial caries can also predispose to further decay around the filling. If the tooth is not kept clean, it may decay again from the edges of the filling. If there is a crown on the tooth and oral care is not paid attention, decay can easily start between the crown and the tooth. As mentioned earlier, if the caries is not treated, the decay can invade the nerve chamber of the tooth and cause a p s. These events will result in root canal treatment or loss of the tooth.
WEAR; Although there are many factors that affect the life of a restoration, the average life of a silver (amalgam) fill, crown or bridge is 5 to 15 years. The average life of composites (plastic-tooth colored filling) is 5 to 10 years. Constant forces applied to teeth and fillings by chewing are the cause of wear. In some cases, porcelain or gold crowns wear out due to the constant grinding of the opposite tooth.
CRACKS; During the day, our teeth are subjected to more physical forces than we can imagine. Even while eating, the square centimeter of our teeth is subjected to pressures worth hundreds of kilograms-force. Biting pressure and chewing on hard foods can cause fine cracks in teeth or restorations.
ABRASIONS; If timely measures are not taken for cracks, the teeth will break or wear out. More expensive and elaborate processes become required. Crowns are recommended for this type of teeth. Sometimes these cracks and abrasions are also found in the porcelain crown. A worn porcelain has expired and begins to crumble. Determining the wear on the existing porcelain crowns during routine controls and taking the necessary precautions will prolong the life of the restoration.
AESTHETIC; Over time, the fillings change color or become stained. Although the change in the appearance of the fillings does not pose a health risk at times, it will cause an unpleasant appearance in the mouth. Nowadays, it is possible to get rid of these unpleasant images by using special filling materials in the same color as the teeth instead of metal-colored fillings.
DENTAL DISEASES; Many patients are unaware that they will lose their teeth due to gum disease. Even teeth without decay can be lost due to gum disease. This process goes very slowly. Bone loss follows gingival recession, and when the supporting tissues of the tooth dissolve, the loss of the tooth is inevitable. When your dentist detects this disease, he will talk about the measures to stop the disease from progressing.
