They provide a translucent, natural-looking color and are less likely to cause dark lines near the gum margin, making them a popular choice for highly visible teeth.<\/li><li>Zirconia crowns: Zirconia is a type of all-ceramic crown known for its high strength, good chewing resistance, and fairly natural appearance.

The answer is no. Dental crowns cannot be whitened in the same way as natural teeth.<\/p><p>Whitening agents such as hydrogen peroxide or carbamide peroxide only work on natural tooth enamel. Meanwhile, dental crowns are made from restorative materials such as ceramic, porcelain-fused-to-metal, or zirconia, so whitening agents cannot penetrate the material or change its color.<\/p><p>Simply put, natural teeth have enamel that can respond to whitening agents, while dental crowns do not. The shade of a dental crown is selected and fabricated from the beginning to match each patient\u2019s natural tooth color. Once the crown is permanently bonded to the tooth, its color generally cannot be changed with conventional teeth whitening methods.<\/p><p><img decoding=\"async\" class=\"wp-image-30451 size-full\" title=\"R\u0103ng s\u1ee9 kh\u00f4ng th\u1ec3 t\u1ea9y tr\u1eafng r\u0103ng\" src=\"https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Boc-rang-su-co-tay-trang-duoc-khong.jpg\" alt=\"R\u0103ng s\u1ee9 kh\u00f4ng th\u1ec3 t\u1ea9y tr\u1eafng r\u0103ng\" width=\"900\" height=\"600\" srcset=\"https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Boc-rang-su-co-tay-trang-duoc-khong.jpg 900w, https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Boc-rang-su-co-tay-trang-duoc-khong-300x200.jpg 300w, https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Boc-rang-su-co-tay-trang-duoc-khong-768x512.jpg 768w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-274966bf elementor-widget elementor-widget-text-editor\" data-id=\"274966bf\" data-element_type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"color: #003366;\"><b>&gt;&gt;&gt; READ MORE: <a href=\"https:\/\/smilux.vn\/en\/can-teeth-affected-by-dental-fluorosis-be-whitened\/\">Can Teeth Affected by Dental Fluorosis Be Whitened<\/a>?

However, their surface may still become dull, stained, or lose its shine after a period of use. This condition is often caused by the following factors:<\/p><ul><li>Type of dental crown used: Dental crowns are commonly divided into porcelain-fused-to-metal crowns and all-ceramic crowns. Porcelain-fused-to-metal crowns have an inner metal framework, which may oxidize over time. This can cause a dark shadow around the gum margin or tooth root area, making the smile look less aesthetic.<\/li><li>Improper crown placement technique: When placing dental crowns, the dentist needs to reshape the natural tooth at the proper ratio and ensure the crown fits closely over the prepared tooth. If the crown does not fit properly, has an open margin, or affects the bite, food debris and plaque may accumulate around the gumline. Over time, this area can become discolored and may even affect the natural tooth underneath.<\/li><li>Frequent consumption of staining foods and drinks: Coffee, tea, red wine, colored soft drinks, or foods with strong pigments can adhere to the surface of dental crowns, making them appear duller over time.<\/li><li>Poor oral hygiene: If you do not brush thoroughly or use dental floss or a water flosser, plaque can easily build up around the crowns and gumline. This not only makes the teeth look less bright but may also lead to bad breath, gum inflammation, or decay in the natural tooth beneath the crown.<\/li><li>Smoking: Nicotine and tar in cigarettes can create yellow-brown stains on dental crowns, especially around the cervical area of the tooth and between the teeth.<\/li><li>Long-term use of dental crowns: After many years of chewing, the crown surface may lose its gloss, develop tiny scratches, or become more prone to staining. This is why many patients feel their dental crowns no longer look as bright and beautiful as when they were first placed.<\/li><\/ul><p>To better understand why dental crowns may lose their original shade, you can read more in this article: \u201c<a href=\"https:\/\/smilux.vn\/en\/do-teeth-turn-yellow-again-after-whitening\/\"><span style=\"color: #003366;\"><b>Do Teeth Turn Yellow Again After Whitening?<\/b><\/span><\/a>\u201d<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-30452 size-full\" title=\"R\u0103ng s\u1ee9 sau m\u1ed9t th\u1eddi gian s\u1eed d\u1ee5ng c\u00f3 th\u1ec3 b\u1ecb \u1ed1 v\u00e0ng, x\u1ec9n m\u00e0u\" src=\"https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Tai-sao-boc-rang-su-bi-xin-mau.jpg\" alt=\"R\u0103ng s\u1ee9 sau m\u1ed9t th\u1eddi gian s\u1eed d\u1ee5ng c\u00f3 th\u1ec3 b\u1ecb \u1ed1 v\u00e0ng, x\u1ec9n m\u00e0u\" width=\"900\" height=\"600\" srcset=\"https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Tai-sao-boc-rang-su-bi-xin-mau.jpg 900w, https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Tai-sao-boc-rang-su-bi-xin-mau-300x200.jpg 300w, https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Tai-sao-boc-rang-su-bi-xin-mau-768x512.jpg 768w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-35d43ef2 at-heading-animation at-animation-heading-none elementor-widget elementor-widget-heading\" data-id=\"35d43ef2\" data-element_type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\"><span class=\"ez-toc-section\" id=\"Tips_to_Keep_Dental_Crowns_Bright_at_Home\"><\/span>Tips to Keep Dental Crowns Bright at Home<span class=\"ez-toc-section-end\"><\/span><\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-67d119ff elementor-widget elementor-widget-text-editor\" data-id=\"67d119ff\" data-element_type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Based on the causes mentioned above, dental crowns cannot be whitened with bleaching agents like natural teeth. However, with proper at-home care, you can help reduce staining and keep the crown surface cleaner, brighter, and shinier.<\/p><ul><li>Maintain proper oral hygiene: You should brush your teeth at least twice a day with a soft-bristled toothbrush, using gentle movements to avoid irritating the gums and the natural tooth structure beneath the crown. In addition, dental floss, a water flosser, or mouthwash can help remove food debris and plaque between the teeth.<\/li><li>Adjust your diet: Limit frequent consumption of coffee, tea, colored soft drinks, heavily pigmented foods, sugary foods, and starchy foods. After eating or drinking staining foods and beverages, you should rinse your mouth or drink water to reduce the risk of stains adhering to the crown surface.<\/li><\/ul><p>Note: Do not use at-home whitening products without professional guidance. Whitening agents only work on natural teeth and cannot change the color of dental crowns. Using unsuitable whitening products on your own may cause tooth sensitivity, gum irritation, or affect the restored tooth area.<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-30453 size-full\" title=\"B\u00ed quy\u1ebft l\u00e0m r\u0103ng s\u1ee9 s\u00e1ng m\u00e0u t\u1ea1i nh\u00e0\" src=\"https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Bi-quyet-lam-rang-su-sang-mau-tai-nha.jpg\" alt=\"B\u00ed quy\u1ebft l\u00e0m r\u0103ng s\u1ee9 s\u00e1ng m\u00e0u t\u1ea1i nh\u00e0\" width=\"900\" height=\"600\" srcset=\"https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Bi-quyet-lam-rang-su-sang-mau-tai-nha.jpg 900w, https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Bi-quyet-lam-rang-su-sang-mau-tai-nha-300x200.jpg 300w, https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Bi-quyet-lam-rang-su-sang-mau-tai-nha-768x512.jpg 768w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4b131f3 elementor-widget elementor-widget-text-editor\" data-id=\"4b131f3\" data-element_type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"color: #003366;\"><b>&gt;&gt;&gt; READ MORE: <a href=\"https:\/\/smilux.vn\/en\/can-teeth-with-cavities-be-whitened\/\">Can teeth with cavities be whitened<\/a>?
