The answer is NO. Patients should not undergo teeth whitening directly while they are experiencing tooth decay.<\/p><p>Before whitening their teeth, patients need to have their tooth decay treated first. Once the decayed tooth has been properly treated, the pain has subsided, and the tooth structure is healthy enough, the dentist may then recommend teeth whitening to improve tooth color.<\/p><p>Tooth decay is a condition in which the tooth structure has been damaged by bacteria. When the cavity progresses deeper inside the tooth, the tooth often becomes more sensitive to temperature, chewing forces, and active ingredients that come into direct contact with the tooth surface. If teeth whitening is performed at this stage, patients may experience the following problems:<\/p><ul><li>Increased tooth sensitivity: When the whitening agent comes into contact with the damaged area of the tooth, it can make the tooth noticeably more sensitive, especially when the cavity has spread into the dentin layer.<\/li><li>Prolonged toothache: A decayed tooth is already weakened and easily irritated. When further exposed to whitening agents, the pain may increase, affecting eating and daily activities.<\/li><li>Dental pulp irritation: If the cavity is close to the pulp or there are signs of pulpitis, the whitening agent may further irritate the pulp, causing the inflammation to progress more severely.<\/li><li>Increased risk of infection: An untreated cavity allows bacteria to continue developing. Whitening at this stage does not address the underlying condition; on the contrary, it may make the tooth more vulnerable to damage.<\/li><\/ul><p><img decoding=\"async\" class=\"wp-image-30140 size-full\" title=\"R\u0103ng s\u00e2u c\u1ea7n \u0111i\u1ec1u tr\u1ecb \u1ed5 vi\u00eam tr\u01b0\u1edbc r\u1ed3i m\u1edbi t\u1ea9y tr\u1eafng r\u0103ng\" src=\"https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Rang-sau-co-tay-trang-duoc-khong.jpg\" alt=\"R\u0103ng s\u00e2u c\u1ea7n \u0111i\u1ec1u tr\u1ecb \u1ed5 vi\u00eam tr\u01b0\u1edbc r\u1ed3i m\u1edbi t\u1ea9y tr\u1eafng r\u0103ng\" width=\"900\" height=\"600\" srcset=\"https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Rang-sau-co-tay-trang-duoc-khong.jpg 900w, https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Rang-sau-co-tay-trang-duoc-khong-300x200.jpg 300w, https:\/\/smilux.vn\/wp-content\/uploads\/2026\/06\/Rang-sau-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-c75359b elementor-widget elementor-widget-text-editor\" data-id=\"c75359b\" 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 style=\"color: #003366;\" href=\"https:\/\/smilux.vn\/en\/can-teeth-affected-by-dental-fluorosis-be-whitened\/\">Can Teeth Affected by Dental Fluorosis Be Whitened<\/a>?

To undergo this method, patients must have their tooth decay treated first.<\/p><p>In cases of mild tooth decay, the dentist will remove the decayed tissue and restore the tooth with a dental filling. Conversely, if the tooth is more severely damaged, painful, or has affected the pulp, the dentist may recommend <strong><a href=\"https:\/\/smilux.vn\/en\/root-canal-treatment-services-in-ho-chi-minh-city\/\">root canal treatment<\/a><\/strong>, dental restoration, or extraction if the tooth can no longer be preserved.<\/p><p>After oral health problems have been thoroughly treated, the dentist will re-evaluate the enamel, dental pulp, and gum condition.
