Still curious about the specifics of cold light whitening as part of cosmetic dentistry? We'll now unveil the mystery behind this procedure by detailing material preparation, treatment precautions, cold light whitening device operation steps, and session duration.
Our accompanying medication comes in individually packaged portions per person. Upon opening, you will find the following components: polishing sand (mixed with water and used in a polishing cup to polish the patient's tooth surface, removing soft deposits and plaque), lip balm and cotton swabs, a lip shield (worn over the mouth opener to protect the skin around the mouth),damp-proof cotton rolls, gingival protection agent (with one thick and one thin delivery tip), three boxes of whitening powder and three bottles of whitening liquid (mixed into a paste during use), mixing spatula, brush (for applying the whitening paste to tooth surfaces), and suction tube.Essential instruments for the procedure are mostly included in the medication kit. Additional items to prepare independently are a slow-speed handpiece, a rubber polishing cup, a light-curing lamp, and a pair of scissors.
1) The patient must wear protective eyewear throughout the entire treatment to prevent foreign objects from entering the eyes.
2) Apply lip balm (petroleum jelly) to the patient before using the retractor to prevent corner abrasions. After applying gingival protectant, spread any remaining lip balm over soft tissues to reduce mucosal dryness.
4) Thoroughly dry tooth surfaces and gingival margins before applying gingival protectant. Failure to do so prevents complete sealing of the gingival sulcus, potentially causing marginal bleaching.
5) Cover cervical wedge-shaped defects and severe enamel cracks with gingival protectant to prevent patient discomfort during treatment.
6) The gingival protectant must completely seal the gingival sulcus to prevent direct contact between the whitening agent and the gums. It is generally applied 3mm above the gingival margin. Avoid prolonged exposure of the light-curing lamp to the patient's soft tissues, as the high temperature generated by the lamp can cause discomfort.
7) Mix the whitening agent into a paste. When blending, avoid adding all liquid to the powder, which would make the paste too thin. Conversely, avoid excessive thickness—the paste should hold its shape when lifted with the provided small brush without dripping. Crucially, unused whitening paste must not be reused, as exposure to air reduces the concentration of peroxides, significantly diminishing treatment efficacy.
8) During the procedure, avoid dripping whitening agent into the patient's mouth. After each eight-minute cycle, use a strong suction device to remove the whitening agent (never rinse with water). This saves time without compromising results. Wiping with cotton rolls risks spilling agent into the mouth; if this occurs, immediately suction it out.
