Identifying internal and external stains for teeth whitening near Pickering

Dr. Amir Awadalla at Esquire Dental Center, Providing Internal Teeth Whitening

Discoloration has a way of creeping up on you, stealing the vibrancy and beauty of your smile. If you have noticed that your teeth are not as bright as they once were and that they are not an accurate reflection of your internal beauty, you will be happy to learn that professional teeth whitening services in Pickering, North York, and Scarborough are very affordable and very effective.

Due to the availability of over the counter whitening products, this is the route many people initially take in their quest to brighten their smile. Rarely do excellent results come from such systems, which are not designed for the individual. In fact, teeth whitening may be completely ineffective on certain types of stains, which is another reason for seeing a dentist for your cosmetic needs.

Internal Vs. External Staining

In most cases, discoloration is the result of years of settling in which particles from foods and beverages accumulate in the pores of enamel. This external staining occurs over time, with teeth becoming dull and then yellowed as these particles block light from reflecting off enamel. During professional teeth whitening, whether performed in the dental office or at home with prescribed bleach solution, colored molecules in pores are broken up gradually. When the procedure is performed in the office, this process is completed through light activation and multiple applications in a visit that lasts about an hour. When home whitening is done, each daily application further lifts the color of teeth until the desired shade and vibrancy is achieved.

Teeth may also be stained from the inside out. This is far more rare but a problem that must be identified if results are to be achieved. Think of the frustration that must occur after multiple attempts at teeth whitening using the wrong method, just because the type of stain was not pinpointed. Internal stains, also called intrinsic stains, are typically the result of some type of medication. Individuals who were prescribed tetracycline during their childhood, for instance, may notice that teeth have a sort of grey tinge to them. Teeth may also become “spotted” as a result of too much ingested fluoride in childhood.

Intrinsic stains such as these will not respond to teeth whitening using any strength of bleach. For this reason, the dentist may recommend brightening the smile by disguising discoloration behind beautiful porcelain veneers.
