Teeth whitening is a dental procedure that lightens or removes stains, yellowing, and other discolouration. We invite you to call Isen Dental clinic serving all of Toronto and especially North York.. Don’t you deserve a brilliant smile?

Patients can’t stop talking about the benefits of professional whitening, so whitening has become one of the most popular procedures in most dental offices. Teeth whitening often leads to better self-confidence, which can positively affect one’s career, as well as social pursuits. With two distinct options, in-office and home whitening, the Isen Dental Clinic patients can enjoy the results they desire and the convenience of treatment that suits their schedule.

Why whiten your teeth?

A bright, easily shared smile conveys confidence, youth, and good health. Many factors can discolour your pearly-white tooth enamel, though. The two main categories of dental stains are extrinsic, or external, and intrinsic, or internal. Here are examples of each, what causes them, and how we whiten teeth in each situation:

Extrinsic dental stains: Extrinsic dental discolouration develops when staining agents buildup on the surface of teeth. This type of staining can be treated with professional chemical teeth whitening, either in our office in a single appointment or at your home over 7 to 14 days.
• Dark beverages and foods – coffee, tea, red wine, colas, dark sauces, etc.
• Acidic beverages and foods (make teeth more susceptible to staining) – citrus, wines, vinegar, etc.
• Tobacco use, smoking or chewing
• Time – teeth tend do discolour as we age, due to exposure to staining elements and thinning enamel

Intrinsic dental stains: Intrinsic stains occur inside teeth, beneath or inside tooth enamel. Chemically bleaching, or oxidizing, tooth enamel will not remove intrinsic stains. In some cases, chemical whitening can lighten enamel so that fluorosis lines are less obvious, but the white lines (stains) remain. To whiten teeth with intrinsic stains, restorative dentistry is usually recommended. Dark fillings and metal-based crowns can be replaced with all-ceramic or zirconia restorations. Thin enamel, fluorosis, and tetracycline stains can be covered with a ceramic or composite resin dental veneer.

Thin dental enamel – this can be natural or caused by acid erosion, but thin enamel allows yellowish dentin to show through, making teeth look yellowed
• Fluorosis – white, horizontal lines on teeth caused by ingesting fluoride in youth
• Tetracycline use – while in the womb or during childhood, tetracycline drug use (antibiotics) can cause a single tooth or all teeth to look off-white
• Dark fillings or metal-based crowns – these restorations can show through a semi-translucent tooth, making it look shadowy and unhealthy
