**Dental laminate loss** usually occurs due to reasons such as low quality **dental laminate** or glue, improper installation, decay of the underlying tooth, grinding teeth, impact, chewing hard objects, wear and tear, and lack of oral hygiene, and is accompanied by symptoms such as loosening, sensitivity, cracking, discoloration, and gingivitis; If the laminate falls, you should remain calm, collect the piece and go to the dentist immediately without gluing it arbitrarily, because not replacing the laminate in time can cause decay, sensitivity, gum disease and infection. By choosing a specialist dentist, observing hygiene, avoiding harmful habits and visiting regularly, you can prevent laminates from falling out, and the replacement cost will vary from 4 to more than 20 million tomans per tooth, depending on the type of laminate and the doctor's expertise, so that in minor cases it is possible to glue or repair with dental composite, but in serious damage, complete replacement is necessary. **Reasons and causes of tooth laminate falling** As mentioned, laminates are covers that are attached to the teeth, and if the installation of laminate covers is not done correctly, it is more likely to fall out in the long run. In the following, we mention the most important factors that can cause the laminate to fall. ### 1- The low quality of the laminate used If the quality of the laminate that has been used as a dental covering for your teeth is low and substandard, it can cause many problems, and one of the main ones is falling and reducing the lifespan of the laminates. Usually, laminates that are of lower quality cannot withstand various pressures such as gas or gentle blows and even cold and heat, and for this reason, there is a possibility of them falling or separating from the tooth enamel surface. ### 2- Laminate expiration date Every laminate of every brand and of every quality has an expiration date. If the expiration date of the laminate has passed, if the dentist uses it, it is as if he has used a laminate that has completely lost its properties, and for this reason, the strength of the laminate's adhesion to the surface of the tooth should decrease, and as a result, it will loosen and fall off. ### 3- Teeth grinding or tooth wear When a person has the problem of grinding teeth, a lot of pressure is applied to the teeth that are laminated. Grinding teeth means grinding teeth against each other completely involuntarily, and in this case, a person may do this for various reasons, such as stress or anger, and even tics or during sleep. In this case, to treat it, a person should use a night guard or tooth protector when grinding teeth. ### 4- Lack of proper preparation of the tooth surface When the dentist wants to install laminate veneers, he must carefully prepare the tooth surface for installation. so that the right amount of tooth grinding is done and the surface is completely ready for gluing the laminates. If this work is not done correctly, the adhesive of the laminates will not stick well on the surface of the tooth, and as a result, the laminate will not be properly attached to the tooth and will eventually cause the laminates to fall off. ### 5- Use of inappropriate adhesive materials If the glue used to stick the laminate veneers on the teeth is inappropriate or of poor quality, it will reduce the strength of adhesion between the laminate and the surface on the tooth, as a result, in the shortest possible time, as a result of very simple blows or chewing the material, the laminates will easily loosen or fall off and separate them from the tooth surface. ### **6- Chewing hard foods and bad dental habits** Chewing very hard foods, biting nails, pens, eggshells, or similar habits put too much pressure on the teeth, which can cause the laminate to crack, fill, or fall off. ### **7- Applying too much pressure to the laminated tooth** Direct blows to the face, accidents, contact sports without a mouth guard, or unexpected high pressure on the tooth can cause the laminate to detach. These impact forces can destroy the laminate connection from the tooth surface and lead to its falling. ### **8 - Improper installation of laminates** If the dentist did not install the laminate correctly or if he used low-quality glue and materials to attach the laminate. Because the laminate glue plays an important role in increasing the lifespan and durability of the laminate, and if it is of poor quality, this durability will decrease. ### **9- Aging or wear of laminates** If you have been using laminates for a long time, if you have not taken care of them, there is a possibility of them falling. The more laminates are used, the more they come into contact with food and the more they are used for chewing. ### **10- Tooth decay under the laminate** Laminates are a type of tooth coating and do not decay by themselves, and these are the teeth that suffer from tooth decay. Usually, this decay was either before the installation of the laminate and was not treated, or it was caused after the installation of the laminate due to the accumulation of bacteria and lack of proper care. ### **11- Physical damage and strong impact to the laminate** Even natural teeth do not have the ability to withstand severe impacts and a series of injuries, let alone laminates. Laminates are thinner than natural teeth and their resistance is lower than natural teeth in the best case. In case of a direct hit to the laminate, there is a definite possibility of breaking, chipping or cracking. ### **12- Non-observance of oral and dental hygiene and unhealthy habits** If you don't take oral hygiene seriously, for example, you don't brush your teeth or don't use dental floss, your natural teeth will also get damaged. Because there are natural teeth under the laminates, it is possible for bacteria to accumulate on the veneer and then penetrate the teeth under the laminate. Even bad habits such as untying knots and packaging with laminate, chewing hard objects such as candy or breaking nuts and snacks, and factors such as teeth grinding or involuntary clenching of teeth, cause the laminate to fall and loosen. ** Signs and symptoms of tooth laminate loss ** Falling or loosening of the laminate is very obvious and can be easily recognized, but if you want to check this matter professionally, if you see the following signs, you definitely need to go to the dentist for an examination. - Feeling of lamination or non-adhesion of the laminate. - Sensitivity of laminated teeth to heat, cold and pressure. - Local pain or discomfort when biting and chewing with laminated teeth. - Discoloration, cracks or splits on the laminate. - Gum inflammation or bleeding around the laminated tooth. - Bad breath and bitter taste or an infection in the mouth due to the accumulation of bacteria. **Methods to prevent dental laminate from falling** As mentioned, laminate does not fall by itself and it is bad habits and lack of care that cause it to fall.

Repair of broken or fallen laminate The repair of broken or fallen laminate is usually done in three ways, depending on the type and severity of the damage: ### Re-gluing the fallen laminate If the laminate is completely removed and has no cracks or breaks, the dentist can reattach it to the tooth after cleaning with a special adhesive. This method is quick and inexpensive, and there is no need to make a new laminate. ### Restoration with composite resin If the laminate is fractured or has small chips or minor cracks, the dentist can fill the damaged space using a composite material of the same color and restore the shape and appearance of the laminate. This method can shorten the repair time, but the color of the composite may not match with the laminate after some time. ### Replacement of torn laminate If the damage is serious and the laminate cannot be repaired, the laminate must be removed and a new laminate made and installed. This method is more time-consuming and expensive, but it has permanent and better quality results. **Consequences of not replacing the fallen or broken laminate** If the laminate of your teeth falls, the wisest thing is to replace and treat it, if you don't replace the laminate on time, the following complications are more likely to occur to you. - Increased sensitivity of teeth under laminate to cold, heat and pressure. - Color change and malformation of the tooth under the laminate. - Increased caries and the possibility of cavities in the teeth under the laminate. - Moving and changing the position and movement of teeth. - The possibility of gum diseases and gum inflammation and swelling. - Possibility of tooth infection such as tooth abscess and damage to adjacent teeth. **What is the price of dental laminate replacement?** The price of laminate replacement in 1404 depends on various factors such as the type of laminate, the type of raw materials, the brand of laminate, the expertise of the dentist and the number of teeth needed for replacement. In general, the price of each laminate unit is reported to be between 4 million and 13 million Tomans and even higher. - Ceramic laminate of each tooth costs about 4 million to 8.5 million tomans. - The price of more specialized laminates such as Imax and Feldspatik is between 8.5 million and 13 million Tomans. - To replace high-quality laminates, the price of each tooth can increase to about 24 million Tomans.
