Hydrogen peroxide and its close relative, carbamide peroxide (which quickly breaks down into hydrogen peroxide), penetrate the enamel and oxidize the dark pigmented molecules within the hard tooth structure itself. By breaking down the dark-colored molecules, it literally whitens the underlying color of the tooth to a whiter shade. Teeth whitening performed by your dentist can make your teeth shine faster. The whitening solution is usually much stronger than home kits. In addition, heat, light, or a combination of the two can be used to accelerate and intensify the whitening process.
Teeth whitening is any process that brightens the color of a tooth. Whitening can be achieved by physically removing the stain or by means of a chemical reaction to lighten the color of the tooth. Bleaching is defined here as the chemical degradation of chromogens. The active ingredient in most whitening products is hydrogen peroxide (H2O), which is supplied as hydrogen peroxide or carbamide peroxide.
Carbamide peroxide is a stable complex that decomposes in contact with water to release hydrogen peroxide. Because carbamide peroxide releases hydrogen peroxide, the chemistry of most teeth whitening is that of hydrogen peroxide. Because the teeth are porous, the whitening gel is absorbed by the enamel and dentin layers of the tooth. The active ingredient in whitening gels is hydrogen peroxide, which removes stains and is then safely absorbed by the body. Most over-the-counter whitening products use low concentrations of hydrogen peroxide, while cosmetic dentists use higher concentrations for faster and more effective results. Home whitening kits can take the form of a gel or paste that is applied to the teeth with a brush or in the form of adhesive strips.
The new research also focuses on optimizing whitening procedures to reduce tooth sensitivity and increase the persistence of whitening. Some of the best at-home teeth whitening options meet ADA acceptance to lighten superficial and deeper stains. There are some newer whitening strip products that only require a 30-minute application per day and have the same whitening purpose as two-a-day products. Teeth whitening can temporarily cause teeth to become sensitive or uncomfortable for people who already have sensitive teeth. However, the higher the percentage of peroxide in the whitening solution, the shorter the application to the teeth. Teeth whitening works best for people with yellow teeth and is less effective for people with brown teeth.
Teeth whitening methods include sanding stains, whitening, ultraviolet (UV) light therapy, and more. In simpler terms, hydrogen peroxide dissolves stains from the enamel and dentin layers to whiten teeth. Turmeric is an all-natural product, making it a desirable alternative to less natural over-the-counter tooth whiteners. If the stains are more noticeable, you can try a home whitening kit or talk to your dentist about in-office whitening sessions. Whitening gels are peroxide-based gels that are applied with a small brush directly to the surface of the teeth.
Even if the whitening gel is only on the teeth for a limited period of time, it will still be effective for the first 24 hours after application. In general, the addition of LED lights to whitening procedures has improved the effectiveness of whitening agents, leading to brighter, whiter smiles. The effectiveness of activating light is controversial, as numerous studies have found improvements in short- and long-term whitening, as well as studies that have not found any effect on whitening. Teeth whitening can be an effective way to brighten your smile and improve your confidence.
