Despite how fastidious an individual is, the teeth will always change its appearance and color. The youthful glow and sparkle of young teeth will over time lost its sheen as the enamel starts developing tiny crevices that will in the end lose the crystalline rods in the tooth, thinning the enamel making the teeth more transparent and showing through the yellowish color of the dentin. Even discounting this natural aging of the teeth, dietary habits, food options, medication, lifestyles, health conditions and many other reasons will develop the small fractures in the enamel allowing debris to gather between the spaces staining the teeth.
Extrinsic staining and intrinsic staining are the two basic types at which the teeth develop stains and discoloration.
Extrinsic stains are created in the top of the teeth that resulted from the accrual of food debris and color. While superficial stains and discoloration could be removed by prophylactic cleaning and brushing, there are stains that are a little more stubborn and could accumulate between the spaces of the small cracks in the tooth that would need bleaching to remove the stains. When the stains are not effectively removed and stays on the teeth for a period of time, this could penetrate deeper into the dentin which might require extensive methods.
Those stains that form beneath the enamel are intrinsic stains. Previously, intrinsic stains are believed to be resistant to remedies although today most of it could be taking away with close supervision from qualified professional people. Intrinsic stains are caused by the natural action of aging, trauma to the tooth, exposure to drugs containing tetracycline and flourosis.
Other factor that stains the teeth is grinding. Grinding often assigned to stress accelerates micro cracking of the tooth enamel that will hold tiny debris to be accumulated. It also causes the edges of the tooth shade darker, faster. Another big factor is smoking. Nicotine is brownish in color that may stick in the enamel of the tooth and even soak in its structure causing internal discoloration. Red wine can be beneficial to the heart but it incorporates a high concentration of tannins that produces staining fast.
DNA. All teeth are translucent to some degree. There are people though that are born with teeth that are more translucent than most. Teeth that are more translucent tend to show more staining than those with more opaque teeth.
Teeth transparency is the only known teeth condition today that couldn't benefit from teeth whitening and teeth bleaching. On the other hand, no sum of teeth bleaching will whiten teeth more than its natural color. In some situations, it could artificially be done but never recommended.
Regardless of how teeth cleaning and bleaching is done, anything involving cosmetic enhancements and restoration is subjective that changes from one individual to another. There will invariably be limits to this that are oftentimes the grounds for the feeling of well being or let-down.
A good point consequently before any teeth bleaching and bleaching is done is ask a realistic assessment from the dentist.
