** Removal or removal of composite or removal of tooth composite** is done for cases such as fracture, discoloration, decay or replacement with dental laminate. This work is done with methods such as sanding, drill, irabrasion or laser and during stages including examination, anesthesia, removal of veneer and tooth polishing. Its possible complications are sensitivity, tooth enamel damage or gingivitis, and its cost usually varies between 500 thousand and 2 million Tomans for each tooth. After removal, replacements such as new **composite teeth**, laminates or dental crowns can be used and this should only be done by a specialist dentist. **How is composite removal and what is composite removal** There is a possibility that some people who have composite teeth do not get results. These people are reluctant to do composite for different reasons, or for other reasons, they need to remove the coating from their teeth. You should know that it is possible to remove or remove the composite and the dentist can use special tools to remove it from the tooth and return your previous tooth to you. But this work must be done carefully and it has tips, steps, methods and complications that you must fully familiarize yourself with before doing and removing the composite from your teeth, which we will talk about comprehensively in the following. **Reasons and causes of tooth composite removal** It is not possible to remove the composite simply, and there must be an acceptable reason for its removal, because its removal can have different consequences for each person. Among the most important reasons for removal and removal of composite, the following can be mentioned: ### **Composite removal due to basic shape change** Usually, this reason is because the result obtained after installing the composite coating has not become what it should have become. For example, its appearance is not good and it has crookedness or sharpness and a bad shape or even a color inconsistent with your natural teeth. ### **Composite removal due to breakage or cracking** Often, composite removal occurs when a person does not follow the care and recommendations given by the dentist after installation. For example, chewing on hard objects with a composite tooth or opening knots and packages and even getting hit in the event of an accident will break the composite and must be removed for repair or replacement. ### **Composite removal due to tooth decay underneath it** Usually, due to lack of oral and dental hygiene and the use of daily toothbrushes, dental floss and special mouthwashes, there is a possibility of tooth decay under the composite coating. Even this issue can happen due to the lack of proper installation or the use of low-quality materials. For this reason, the veneer must be removed to treat tooth decay such as tooth extraction. ### **Composite removal due to its color change and wear** After a long period of time, composite materials lose their properties and usually the lifespan and durability of composite is between 5 and 10 years in the best conditions. For this reason, to replace it or repair it, the cover must be removed and a new cover replaced. ### **Composite removal due to the desire to replace it with laminate** Some people like the look and shape of dental laminate more than composite, and even though they have done composite, they also like to do dental laminate. Because it is not possible to install laminate veneers on composite, the composite veneers must be removed and if there is tooth decay or tooth infection, treatment should be done and then laminate veneers will be installed on the tooth. **The best methods of removing tooth composite** In order for the dentist to be able to remove the composite coating from your teeth, he can use different methods and the dentist must diagnose and confirm this method according to your teeth. Among the most important methods of composite removal, the following can be mentioned: ### **Composite removal with sandpaper sheets** In this method, sanding sheets are used to remove and grind composite materials from the tooth, the advantage of which is access to all the corners and edges of the tooth; But at the same time, the speed of doing it is low and there is a possibility of damaging the tooth enamel. ### **Composite removal with carbide drills** Carbide drill is a special dental drill that is much faster than sanding sheets. In this case, the dentist can remove the composite coating from the tooth faster; But the main problem is scratching the tooth enamel. ### **Composite removal with air abrasion technology** One of the most advanced methods for composite removal is the use of air-assisted spraying of very fine aluminum oxide particles on the composite on the tooth. Among the advantages of this method, we can point out that the tooth enamel is not damaged, without feeling a single bit of pain and without the need for anesthesia. ### **Composite removal with micro-etcher** A micro-etcher is a tool that can remove composite material from the tooth by spraying abrasive particles on the surface of the tooth with the help of air. Of course, you should know that micro-etcher cannot be used for many composite materials. ### **composite removal with laser** This method is more advanced than other methods and has a higher cost than other methods. In this, the water in the composite material is dissolved by hydrolysis with the glue inside it, and its molecules are divided into small particles. In the same way, the composite resin adhesive is completely dissolved and the material is easily removed from the tooth. This method is faster than other methods and has the least amount of damage to tooth enamel. **Steps and how to remove tooth composite** To remove or remove the composite, the following steps must be taken so that it can be completely removed or replaced with a new composite veneer. 1. Dental examination by a dentist to assess the need for composite removal 2. Injection of local anesthesia to reduce pain 3. Removing the composite with different tools such as sandpaper, carbide drill, abrasive air or laser 4. Cleaning and disinfection of the tooth surface after removal 5. Polishing the tooth surface to make it smooth and shiny This process is usually done in one session, and the choice of appropriate method depends on the condition of the patient's teeth and the dentist's equipment. **Complications of tooth composite removal** Composite removal, like other methods, has mild side effects and may only happen to some people. But the most important of these complications can be mentioned below. - Sensitivity of teeth to heat, cold, sweet and sour, which is usually temporary - Damage to tooth enamel in case of incorrect removal, which can lead to tooth decay or weakness - Changing the color of the teeth after removal, which may make the appearance of the teeth different - Temporary discomfort and pain in teeth or gums - Gum inflammation and irritation if the composite is close to the gum line - The possibility of tooth cracking or filling due to composite removal - Need for restoration or other dental treatments after extraction To reduce these complications, it should be removed by a skilled dentist with the right tools and method, and usually after removing the composite, a new composite or temporary cover is placed to protect the tooth. **Price and cost of dental composite removal** The price and cost of dental composite removal varies and depends on the following factors: - The number of teeth whose composite must be removed - Placement of teeth (front or back teeth) - The amount of damage or scratching of the tooth surface - Removal method (traditional tools or laser) - Experience and skill of the dentist - Clinic and geographical area of work In general, the cost of removing it usually varies between 500,000 and 2,000,000 Tomans for each tooth. To remove that many teeth, the total cost will be higher. Costs associated with post-removal restoration and polishing may also be added.
