What is layered composite and why is it better than normal composite?

**composite layering or layered composite or layered** is an advanced method in cosmetic dentistry, in which **dental composite** materials are placed on the tooth in layers with different colors and transparencies, and each individual layer is hardened with a special light. This method makes the appearance of the tooth more natural, more durable and longer lasting. The stages of composite layering include examination, color selection, tooth preparation, bonding, composite layering, shaping and polishing. The time to perform layered composite is usually 3 to 5 hours and its cost varies. This method is suitable for people who are looking for natural beauty and high durability, and it is possible to repair and take care of it afterwards. Its main difference with ordinary composite is layering, more natural appearance and higher durability. What is composite layering? Dental composite by layering method is a new and innovative method that is welcomed by many dentists and patients today. The main difference between this method and the usual method is how it is done. In the old method, the composite material was one layer and the dentist attached it to the teeth in one step and hardened it with a special light. However, in this method, the composites are placed on the tooth in layers, glued and hardened with light, and the color and healing of the composites range from dark and cloudy to white and bright. In this way, restoration of dentin and tooth enamel has been done and it can provide very high resistance, long lasting and unique beauty to the patient. **Applications of composite layering** The following applications have made layered composite a popular and effective method in cosmetic dentistry to have a beautiful, natural and durable smile. - Repair of broken or filled teeth. - Covering discolored and stained teeth. - Correction of minor irregularities. - Closing empty spaces and small interdental spaces. - Maintaining more of the natural structure of the tooth due to the less need to cut tooth enamel compared to other methods such as dental veneers and dental laminates. **Stages of composite layering** - **Preliminary consultation and examination**: checking the health of the teeth, decay, color and shape of the teeth, and taking pictures or molding if needed. - **Choosing the right color**: According to the color of the patient's natural teeth and face, the color of the composites, which has several types with different colors and transparency, is selected. - **Preparation of the tooth surface**: cleaning and preparation of the tooth surface is done to create proper adhesion between the tooth and the composite. - **Creation of bonding (glue)**: The bonding material is placed on the tooth and hardened with a special light (cure lamp) to provide a base for connecting the composite to the tooth. - **Composite application in layers**: Composites are placed on the tooth in layers and with different thicknesses and colors; Each layer is shaped and then hardened with a special light. - **Final shaping and creation of tooth anatomy**: The dentist creates the final shape and shape of the tooth with special tools for a completely natural appearance. - **Polishing and final finishing**: The surface of the tooth is polished to become smooth, shiny and transparent, which helps the beauty and durability of the composite. - **Final inspection and adjustment of teeth contact**: The contact of upper and lower teeth is checked and minor corrections are made to prevent jaw and chewing problems. **advantages and disadvantages of composite layering** **Care after composite layering** - Avoiding eating hard, sticky and chewy foods until the numbness of the teeth is completely removed. - Avoid eating colored foods and drinks such as tea, coffee, soft drinks, beets and blackberries for 24 hours after the composite so that the color of the composite does not change. - Regular and regular use of a soft toothbrush and dental floss twice a day to maintain oral hygiene and prevent plaque accumulation. - Avoid drinking very hot or very cold drinks to prevent cracking or damage to the composite. - If you feel any sharpness or discomfort while chewing, see a dentist. - If you grind your teeth, be sure to use a night guard or tooth protector. - Avoiding the use of teeth whitening agents and flossing carefully to prevent damage to the composite. Avoid opening hard objects or chewing very hard foods such as ice, pistachios and seeds. - Regular visits to the dentist for a visit and to control the health of the composites. ** Complications of layering composite ** - Tooth sensitivity to cold and heat. - Swelling, inflammation and redness of the gums. - Possibility of fracture or lip filling in case of impact or high pressure. - The possibility of changing the color of the composite in case of consuming colored food. - The need for regular care and oral hygiene. - The possibility of tooth infection and tooth decay under the composite if oral and dental hygiene is not observed. - The possibility of damaging the dental pulp in the case of excessive grinding of tooth enamel. These side effects are usually mild and transient; But they need to choose a skilled dentist and observe post-treatment care. **Learing composite price** In general, **composite layering price** for **each unit (each tooth)** ranges from **1,500,000** **Tomans** to **6,000,000** **Tomans**, which range includes various types of composite materials with different qualities and composite brands. Also, factors such as the place of residence, the experience of the dentist, the type of materials used and the number of teeth on which the composite is done can affect this price. For the entire jaw, this price may be **between 18,000,000 and 60,000,000 Tomans** or more, and for both jaws completely, the cost may reach **30,000,000 and 100,000,000 Tomans**. Also, other factors such as the complexity of the work or the need for side treatments can increase the price. Usually, higher quality composites and reputable brands cost more, but offer durability and a more natural appearance.
