There are two types of tooth stains:
INTRINSIC STAINS (Internal stains): This means the stain occurs from within the tooth. This type of stain cannot be removed by brushing and flossing and sometimes bleaching may not be effective. Some causes of intrinsic staining are the injury to the tooth, certain medications (such as tetracycline) taken during tooth formation stage or an excess fluoride ingested during the formation of teeth.
EXTRINSIC STAINS (External stains): This is staining of the tooth surface. Some sources of extrinsic stains are cigarettes, cigars, paan masala, coffee, tea or foods that contain a lot of spices. This type of staining can sometimes be removed by good tooth brushing habits or by professional oral prophylaxis (scaling).
Occasionally people experience temporary discomfort during the bleaching treatment, such as tooth sensitivity. These symptoms are transient & disappear within one to three days after completion of the treatment. It is important that the manufacturer’s directions are followed precisely.Overall, tooth bleaching under professional supervision is an effective method for whitening the teeth.
Instructions for Home Bleaching
Bleaching is used to enhance your smile by brightening your existing natural teeth. Bleaching will not make crowns, Veneers/Laminates, bonding or existing fillings lighter. If you bleach and have these type of restorations in your smile line you may want to have these changed after you bleach. When you start to bleach we typically have you bleach your upper teeth first when you are bleaching both upper & lower teeth. This will provide you with a comparison so you know just how much your teeth are whitening. Bleaching usually takes 1-2 weeks for the complete result. We cannot predict the exact level of shade changes you will have with bleaching, but it will always make your teeth lighter.
Brush and floss teeth thoroughly prior to placing the tray in your mouth.
Place a small drop of gel in a tray at each tooth site where whitening is desired.
Seat tray completely and firmly onto teeth.
