We check for cavities, periodontal disease, and nerve condition to ensure safe treatment.<\/p>\n<p>As shown in the photo above, we use a shade guide to assess your current tooth color. We discuss your desired level of whiteness and determine the most suitable whitening method. Based on your oral condition and preferences, we&#8217;ll help you choose between office whitening, home whitening, dual whitening, or walking bleach, and establish a treatment schedule.<\/p>\n<p>Please inform us in advance if you need results for a specific event like a wedding, photo shoot, or other occasions. Early consultation allows us to better plan treatment to meet your timeline, as last-minute requests may not be accommodatable.<\/p>\n<h3>\u2461 Pre-whitening Preparation &#8211; Essential Steps for Maximum Effectiveness<\/h3>\n<p>Proper preparation is crucial for optimal whitening results. We recommend Professional Mechanical Tooth Cleaning (PMTC) before whitening treatment.<\/p>\n<p><strong>What is PMTC?<\/strong><br \/>\nPMTC is thorough tooth surface cleaning performed by dentists or dental hygienists using specialized equipment. By removing plaque, stains, and biofilm (bacterial colonies), it helps whitening agents penetrate better for enhanced results. PMTC is also effective in preventing cavities and gum disease.<\/p>\n<h3>\u2462 Whitening Treatment &#8211; Safe Procedures with Attention to Comfort<\/h3>\n<ul>\n<li><strong>Office Whitening Procedure<\/strong>:<br \/>\nThe treatment takes about one hour. We begin by photographing your teeth with a shade guide to document the initial color. We then prepare by protecting your lips and gums with resin barriers. Once ready, we apply Beyond Whitening gel to your teeth. This system mixes the gel in the syringe before each treatment, ensuring fresh agent application. After the prescribed time, we remove the gel. (This process is repeated 2-3 times.) Finally, we photograph your teeth with the shade guide again to document the color change.<\/li>\n<li><strong>Home Whitening Instructions<\/strong>:<br \/>\nWe first create your custom mouth trays (typically ready within a week of taking impressions). Once complete, we&#8217;ll explain the home use procedure. After thorough brushing and flossing, apply the appropriate amount of whitening gel to the trays and wear them for 2-3 hours daily (duration varies by gel concentration) for typically two weeks. The trays feature reservoirs to hold the gel effectively and make application easier. If gel overflows, remove it with a toothbrush or cotton swab to prevent irritation to lips, gums, or cheeks. After wearing, remove trays, rinse your mouth, and clean both teeth and trays thoroughly. Treatment may be adjusted based on sensitivity or individual conditions.<\/li>\n<li><strong>Walking Bleach Procedure<\/strong>:<br \/>\nWe first thoroughly examine the target tooth, including X-rays to verify proper root treatment and absence of periapical lesions. Gaps in root filling or presence of lesions could lead to complications or tooth loss, requiring treatment before whitening. Walking bleach involves placing medication inside the tooth and replacing it several times for gradual whitening. Usually requires 2-3 sessions, though results vary. Chemical reactions may cause pressure and discomfort. If temporary filling dislodges, rinse thoroughly and contact us immediately.<\/li>\n<\/ul>\n<h3>\u2463 Regular Check-ups and Touch-ups &#8211; Maintaining your White Smile<\/h3>\n<p>Whitening effects are not permanent and will gradually reverse over time. Regular maintenance is key to maintaining whiteness.<\/p>\n<p>We recommend check-ups every 3-6 months. During these visits, we examine your oral condition and perform cleaning as needed. Touch-up treatments can effectively address any color regression.<\/p>\n<\/div><div class=\"fusion-text fusion-text-5\"><p><div class=\"fusion-fullwidth fullwidth-box fusion-builder-row-1-1 fusion-flex-container nonhundred-percent-fullwidth non-hundred-percent-height-scrolling\" style=\"--awb-border-radius-top-left:0px;--awb-border-radius-top-right:0px;--awb-border-radius-bottom-right:0px;--awb-border-radius-bottom-left:0px;--awb-flex-wrap:wrap;\" ><\/div><div class=\"fusion-builder-row fusion-row fusion-flex-align-items-flex-start fusion-flex-justify-content-center fusion-flex-content-wrap\" style=\"max-width:1248px;margin-left: calc(-4% \/ 2 );margin-right: calc(-4% \/ 2 );\"><\/div><div class=\"fusion-text fusion-text-5\"><\/div><div class=\"fusion-fullwidth fullwidth-box fusion-builder-row-1-2 fusion-flex-container nonhundred-percent-fullwidth non-hundred-percent-height-scrolling\" style=\"--awb-border-radius-top-left:0px;--awb-border-radius-top-right:0px;--awb-border-radius-bottom-right:0px;--awb-border-radius-bottom-left:0px;--awb-flex-wrap:wrap;\" ><\/div><div class=\"fusion-builder-row fusion-row fusion-flex-align-items-flex-start fusion-flex-justify-content-center fusion-flex-content-wrap\" style=\"max-width:1248px;margin-left: calc(-4% \/ 2 );margin-right: calc(-4% \/ 2 );\"><\/div><div class=\"fusion-text fusion-text-6\"><\/div>\n<\/section>\n<\/div><\/div><\/div><\/div><\/div>\n<\/section>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":5,"featured_media":1908,"parent":0,"menu_order":0,"comment_status":"open","ping_status":"open","template":"","meta":{"footnotes":""},"class_list":["post-3273","page","type-page","status-publish","has-post-thumbnail","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Whitening - SACHI Dental Clinic<\/title>\n<meta name=\"description\" content=\"For teeth whitening in Shiba Park and Mita, visit SACHI Dental Clinic.
