Teeth whitening treatments have gained in popularity. Many turn to this option in a bid to enhance their smile. But, what’s the science behind these treatments?
Understanding the Color of Teeth
Primarily, the color of our teeth is determined by the inner layer, known as dentin, and the outer protective layer, the enamel. Over time, our enamel thins, which may make the dentin more visible, giving teeth a yellowish rather than lustrous white appearance.
The Role of Stains
Stains also play a part in discoloring teeth. There are two types of stains. Extrinsic stains are on the surface of the teeth and are usually due to factors such as food, drink, or tobacco. Intrinsic stains occur inside the tooth, often due to age, trauma, certain types of medication, or excessive fluoride.
The Whitening Process
Teeth whitening treatments work by breaking these stains into smaller pieces. The color becomes less concentrated, making your teeth look brighter.
The active ingredient in teeth whitening products is usually either hydrogen peroxide or carbamide peroxide. These bleaching agents penetrate the enamel and reach the discolored molecules within the teeth. They react with these molecules, breaking the bonds that hold them together. The stain molecules scatter and become less concentrated. The result is a brighter and whiter smile.
Whitening Treatments and Sensitivity
One frequent question about teeth whitening treatments is their potential effect on tooth sensitivity. There is a chance that some people could experience temporary increased tooth sensitivity after a whitening treatment. This is generally due to the peroxide in the whitening product getting through the enamel to the soft layer of dentin and irritating the nerve of the tooth. However, this discomfort should resolve within a few days after the treatment.
Post-Whitening Dental Care
After a teeth whitening treatment, certain steps can maintain the brightness of the teeth. Daily brushing and flossing, along with regular visits to the dentist, are essential. Also, try to avoid foods and drinks that can stain the teeth. When necessary, some people might opt for dental procedures such as tooth crowns in Gonzales, LA.
Conclusion
In sum, the science behind teeth whitening lies in the ability of bleaching agents to break down stains into smaller particles, thereby reducing their color concentration and making teeth appear brighter. While it might cause temporary sensitivity for some, this procedure generally offers an effective way to enhance individuals’ smiles. Regular oral hygiene and a watchful eye on the consumption of stain-causing food and drinks can help maintain this brightness.
