Rhonda Kalasho, DDS, explains that these trays typically use low concentrations of peroxide-based gels, such as 15% hydrogen peroxide or 35% carbamide peroxide. You usually wear a whitening tray ...
The bleaching gel typically contains between 10% and 44% carbamide peroxide, which is roughly equivalent to a 3% to 16% hydrogen peroxide concentration. The legal percentage of hydrogen peroxide allowed to be given is 0.1–6%. [where?] Bleaching agents are only allowed to be given by dental practitioners, dental therapists, and dental hygienists.
In dentistry, debridement refers to the removal by dental cleaning of accumulations of plaque and calculus (tartar) in order to maintain dental health. [1] Debridement may be performed using ultrasonic instruments, which fracture the calculus, thereby facilitating its removal, as well as hand tools, including periodontal scaler and curettes, or through the use of chemicals such as hydrogen ...
The agents most commonly used to intrinsically change the color of teeth are hydrogen peroxide and carbamide peroxide. Oxygen radicals from the peroxide in the whitening agents contact the stains in the interprismatic spaces within the enamel layer. When this occurs, stains will be bleached and the teeth now appear lighter in color.

In addition to brushing, cleaning between teeth may help to prevent build-up of plaque bacteria on the teeth. This may be done with dental floss or interdental brushes.. 80% of cavities occur in the grooves, or pits and fissures, of the chewing surfaces of the teeth, [4] however, there is no evidence currently showing that normal at-home flossing reduces the risk of cavities in these areas.
Hexane and other volatile hydrocarbons (petroleum ether) present an aspiration risk. [26] n-Hexane is sometimes used as a denaturant for alcohol, and as a cleaning agent in the textile, furniture, and leather industries. It is slowly being replaced with other solvents. [27] Like gasoline, hexane is highly volatile and is an explosion risk.
This is a common method used in households to remove a variety of stains. Depending on the stains composition, the stained material is left to soak in a container of warm or cool water and solvent. Such solvents can include laundry detergent, bleach, peroxide, vinegar, or a cleaning product with enzymes.
