Reasons for the yellowing of dental and dental composites

While tooth enamel has a crystalline and compact structure, the composite surface is slightly rougher and has micro-holes that absorb pigments more easily. This difference makes the composite discolor faster than the tooth enamel, even if both are exposed to the same factors. In addition, stains that form on natural teeth can be removed by scaling or bleaching; But composite does not have such a reaction, and to whiten it, you have to turn to more specific methods, such as professional polishing. The main reasons for the yellowing of composite teeth Yellowing of tooth composite usually happens as a result of one or more factors at the same time. Although the appearance of these spots sometimes seems superficial; But their roots can be deeper than what is seen at first glance. In this section, we examine the main causes of this phenomenon so that it can be better prevented or decided to treat it. ### Nutrition Foods that have natural or additive color are directly related to the color acceptability of the composite. Spices such as curry and turmeric, beverages such as black tea, coffee, soda and even some juices have pigments that easily adhere to the composite surface. Repeated consumption of these foods creates a layer of color that darkens the appearance of the composite. ### Tobacco use Nicotine, tar and other compounds in tobacco are not only harmful to the health of the body; Rather, they have a negative effect directly on the color of the composite. These materials easily adhere to the surface of the composite resin and cause a clear color change over time. Even if only a few cigarettes are consumed daily, the effects will be visible over time. ### Weakness in oral and dental hygiene If oral hygiene is not followed properly, microbial plaques and food residues accumulate on the composite surface. These layers provide a suitable environment for the absorption of food pigments. Not brushing regularly, not using dental floss or insufficient mouth washing are effective factors in the tarnishing of composite. ### Low quality composite materials Composites made of low purity materials are less resistant to pigment penetration. These materials have more roughness and their reaction to light, acid and chemical compounds of the mouth is weaker. As a result, yellowing occurs earlier and more intensively. ### Lack of proper polishing after composite installation Final polishing is a step that plays an important role in the longevity of composite beauty. If the surface is not polished well after the installation of the composite, there will be micro-holes that will easily stain. This uneven surface not only looks messy; Rather, it becomes a place for the accumulation of stains and particles. Ways to prevent composite yellowing Fortunately, by following a few simple habits in lifestyle and daily hygiene, it is possible to prevent composite color change. In this section, practical solutions are presented to maintain the whiteness and shine of the composite. ### modification of eating habits Reducing the consumption of colored foods and drinks is the first step to prevent the yellowing of composite teeth. Less use of foods such as colored sauces, saffron and turmeric also has a great effect on maintaining the color of the composite. Also, chewing sugar-free gum can help clean the surface of the teeth. ### Correct use of toothbrush and dental floss Brushing the teeth twice a day with a soft toothbrush and non-abrasive toothpaste helps to prevent colored particles from remaining on the composite surface. Using dental floss after every meal prevents the accumulation of food particles between the teeth and around the composite. It is better to use an electric toothbrush; Because it is more effective in cleaning more completely. ### regular visits to the dentist Periodic visits by the dentist help to detect any discoloration or surface damage in the early stages. It is often recommended to go for an examination and calculus every six months. ### Using suitable mouthwash Alcohol-free antibacterial mouthwashes prevent yellowing of composite teeth by reducing bacteria and colorable particles. It is better to choose mouthwashes that do not have whitening properties so as not to damage the surface of the resin. Is it possible to whiten composite teeth? In this section, applicable methods and their limitations are discussed so that you know what options are available to you in case of tooth composite yellowing. ### Does bleaching work on composite? no Whitening agents used in tooth bleaching do not affect the composite resin structure. This method only brightens the natural enamel, and the color difference between natural and composite teeth may become more visible after it is done. Therefore, bleaching is not a suitable solution for correcting the color of the composite and sometimes even causes more patient dissatisfaction. ### composite polish; The most effective whitening method If the color change is superficial and not too severe, composite polishing by a dentist is one of the best ways to restore the original shine. In this method, a thin layer is removed from the surface of the composite to remove stains, sediments, and minor discolorations. In addition to beauty, polishing also helps oral hygiene and prevents the accumulation of plaque. ### Composite partial replacement or repair in acute cases If the yellowness of the composite is deeper or is caused by surface damage or poor quality materials, there may be a need to replace or repair the discolored parts. Sometimes, only a part of the composite is shaved and replaced with a new material, and in some cases, a complete replacement of one or more veneers is suggested. The decision about this depends on the severity of the color change, the quality of the previous composite and the patient's taste. When should the composite be replaced? Some signs, including the following, clearly signal that it's time to visit the dentist for an update on your teeth's appearance. ### Severe color change or uneven color of teeth If the color of the composites is significantly different from natural teeth or other veneers, the overall appearance of the smile will appear out of sync. This issue attracts more attention especially in the front area of ​​the teeth and may harm a person's self-confidence. In such a situation, replacing the composite is the best way to restore the color harmony. ### Lip chipping or composite surface damage Over time or due to high pressures such as biting hard foods, the composite may suffer from small fractures or chipping. These injuries not only change the appearance of the teeth, but can also cause plaque accumulation and inflammation of the gums. Depending on the extent of the damage, the dentist may suggest partial restoration or full veneer replacement. ### the oldness of the composite The lifespan of the composite depends on various factors such as the quality of the material, the skill of the dentist, and how the patient is cared for; But normally, composites need evaluation after 5 to 7 years. Even if there is no change in color or visible damage, the resin structure may wear out over time and lose its beauty or strength. ### The patient's dissatisfaction with the aesthetic appearance of the composite sometimes the composite is technically sound; But after a while, the patient is not satisfied with the appearance of his teeth due to a change in taste or aesthetic expectations. In such cases, consultation with a dentist about better options such as reshaping or replacing with a new color can have a better result.
