Whether you purchase strips over the counter in a pharmacy, answer an ad on late-night TV or have treatment in your dentistĚs office, all the whitening agents are based on a peroxide solution.
The solution cleans teeth with a bubbling action that removes stains trapped in your teethĚs enamel. Whitener types differ by strength of the peroxide solution and by delivery method.
Your dentist can help you choose the appropriate whitener. Inexpensive over-the-counter products, such as whitening strips, have about 4 per cent peroxide solution and can whiten teeth by two or three shades. In the tray-and-gel solution, the dentist prepares a mouthpiece filled with gel for the patient to wear a few hours every night for about two weeks.
This method has 10 to 15 per cent peroxide, and can whiten the teeth by about eight shades. Powerful whitening systems administered in the dentistĚs office have a concentrated peroxide solution of about 35 per cent. Over the course of a single hour-and-a-half treatment, teeth can be whitened by 12 to 14 shades. So, someone who has quit smoking after 20 years and wants to whiten his teeth may need a more powerful solution than a young person with good dental hygiene who just wants her teeth a little brighter for a special occasion.
