With the expansion of the use of dental cosmetic services, dental composites are known as one of the most common methods to modify the smile design and restore teeth. However, despite the many benefits, in some cases patients face problems such as loosening or even falling of the composite. In this article from Dr. Benianian's dental site, we will examine the possible reasons for the loosening or falling of the dental composite in order to provide solutions for prevention and treatment. What are the reasons for the composite to loosen or fall off the tooth? Dental composite falling can have various reasons. Some of the reasons are related to the patient, others to the dentist, and some to the quality of the composite raw materials. To find these reasons, we reviewed several authoritative scientific articles, including an article entitled "Why Do Composite Fillings Fall Out Easily". Now, we will discuss some of the most important reasons for this problem. ### Inserting too much force into the composite One of the common reasons for tooth composite to fall is excessive force applied to it. A force that can come from various sources such as chewing very hard food, grinding teeth in sleep, strong impacts to the teeth during sports or accidents, or even bad habits such as biting on hard objects. This extra pressure, over time, causes tiny cracks in the tooth composite and reduces its adhesion to the tooth, and eventually leads to the separation of the composite from the tooth surface. For this reason, it is recommended that people who have cosmetic dental composites do not chew very hard foods, or if they have harmful habits such as grinding their teeth, they must use a mouth guard. ### Non-observance of oral and dental hygiene Another reason that leads to dental composite falling or loosening is lack of oral and dental hygiene. Because the accumulation of plaque and mass on the teeth can cause gum inflammation and bone loss around the teeth; An issue that shows the relationship between composite and tooth decay due to poor oral hygiene. These conditions weaken the base of the tooth and, as a result, reduce the adhesion of the composite to the tooth. Finally, the bacteria in the plaque gradually penetrate the adhesive under the composite and weaken it. All these events together lead to loosening and eventually falling of the composite. So in a word, to avoid this problem, it is very important to observe oral and dental hygiene regularly, brush your teeth correctly and use dental floss. ### Consuming acidic foods is the main reason for loosening or falling of the composite If you regularly use some acidic foods such as soft drinks, carbonated juices, citrus fruits and even fruits such as limes, grapes or tomatoes, your tooth composite will become softer over time. As a result, the structure of the composite will change and parts of this material may be discharged (separated) from your tooth. These acids are so harmful to the tooth that they can even penetrate the lower layer of the composite and weaken it from the inside. That is, they not only remove the composite from your tooth, but also cause decay in the tooth under the composite. ### Use of poor quality composite materials Perhaps, we are not exaggerating if we introduce the use of low-quality composite materials as the main reason for composite falling off the teeth. Because the role of the quality of these materials has a great impact on their durability on your teeth. Low-quality composite materials have a weak structure and their adhesion to the tooth is very inappropriate. Because of this, they cannot last long on the tooth. They do not have enough resistance to the pressures caused by chewing, wear and temperature changes, they easily crack or detach from the teeth. However, these are just some of the defects of low-quality composites. Discoloration over time, increasing the possibility of tooth infection and low lifespan are other disadvantages that these composites bring with them. ### Poor quality composite bonding The low quality of bonding or glue used to connect the composite to the tooth is another reason that plays a role in the loosening or falling of the dental composite. Bonding is one of the dental composite steps that plays a very important role in creating a strong and stable bond between the composite and the tooth. Therefore, it is natural that if the bonding does not have the necessary quality, it will lose its adhesion over time and the composite will be easily removed from the tooth. Various factors, such as the use of outdated bonding, incompatibility of bonding with the type of composite, or non-observance of treatment protocols during bonding, can reduce the quality of the bond and, as a result, the composite falls. Therefore, the use of high-quality bonding and strict adherence to treatment protocols by the dentist are of great importance. ### Suffering from gum disease Almost all of us know that tooth inflammation and gum infection cause bone loss around the tooth and create a gap between the tooth and the gum. The distance that even affects the adhesion of the composite with the tooth, reduces it and even causes the composite to be easily removed from the tooth. In addition, bacteria present in gum diseases can penetrate the adhesive under the composite and weaken it. So, it is possible that over time, the composite on your tooth will loosen or dislodge. **Read more:** What is composite polishing? ### Failure to fix primary tooth decay by the dentist Among the other common reasons for tooth composite falling out, we can point out the failure to completely remove the initial decay of the teeth before installing the composite. In this situation, the person's tooth had partial or even total caries before the installation of the composite. But the dentist, regardless of these caries, has started the composite layering process. As a result of this behavior, the bacteria continue their activity under the composite and cause the further spread of decay. As a result, the structure of the tooth is weakened and the adhesion of the composite to the tooth is reduced. For this reason, you should visit the best composite dentist to perform this dental procedure. Before installing the composite, the dentist must carefully examine the teeth, and if there is any decay, treat it completely to ensure the durability and longevity of the composite. ### Low expertise of the dentist in the implementation of dental composite The skill and experience of the dentist in preparing the tooth, choosing the right materials, creating a strong bond and shaping the composite plays a very important role in its durability. Because if the dentist is not skilled enough, mistakes may occur in different stages of treatment. For example, improper preparation of the tooth surface, use of inappropriate materials, creating air bubbles under the composite, or not creating a strong bond between the composite and the tooth, all can cause the composite to quickly detach from the tooth. Therefore, choosing a specialist and experienced dentist to perform dental composite is one of the most important factors to increase its lifespan and durability.
