Teeth whitening strips
Coated with a whitening gel, these thin, flexible strips are designed to conform to the shape of your teeth. They are very convenient and easy to use - and no mixing or shaping is required. What's more, they're discreet enough to be worn at work or while shopping or socializing.
However, whitening strips are less effective at removing stains between teeth than plates and are not suitable for crooked teeth. In addition, saliva can get under the whitening strips, thereby reducing their effectiveness. Some whitening strips are not long enough to last the entire smile and are prone to slipping and falling off.
Crest Whitestrips Supreme containing 14% hydrogen peroxide - the highest concentration allowed for whitening strips today - are prepared in dental offices. These plates are wide enough to cover up to 6 teeth.
Approximate price for a box of 84 strips (3 weeks) is $45. OTC whitening strips cost between $20 and $45.
Tooth whitening products applied
Brushes with applicators are considered to be the easiest way to whiten teeth. The procedure is carried out immediately after meals or regularly throughout the day as an alternative to whitening plates and strips. These bleaches are often referred to as "antidotes" for new stains caused by food, especially red wine.
But dentists are divided about brush-applied bleach. Some consider them useful additions to clinical or "flake" whitening, while others do not yet see any special effect from these whiteners.
Whitening Toothpaste
From a technical point of view, all toothpastes are whitening because they remove plaque from the surface of the teeth. But only a few of them contain the main whitening ingredients: chemical bleaching agents and abrasives in high concentration.
When used regularly, these toothpastes can serve as an adjunct to whitening your teeth. Of course, given that the brushing time is 1-2 minutes, the effect they produce is minimal. But since we brush our teeth every day, some believe that whitening toothpastes are potential whitening boosters.
Toothpastes containing peroxide
Because the foam of the toothpaste spreads throughout the mouth and is swallowed, the percentage of any brightener it contains is low, helping to avoid irritation.
Toothpastes with abrasives
Most toothpastes clean teeth with finely divided abrasives such as silica, alumina, calcium carbonate and baking soda. Whitening toothpastes contain higher amounts of these abrasives, however it is ironic that overuse can cause more staining and darkening of the surface of dental crowns and veneers.
Whitening floss
It may seem that flossing is not an important factor in teeth whitening due to its short-term contact with the teeth (1-2 seconds). But flossing daily for a long time helps to remove stains in narrow spaces between teeth, while even clinical whitening is difficult to deal with these types of stains.
Whitening floss differs from regular floss in silicon content.
