What Causes Teeth Discolouration?
Over time, your teeth can change colours due to a number of factors:
In-Office vs. At-Home Teeth Whitening
You may see different over-the-counter (OTC) bleaching products online or at your local pharmacy, such as toothpaste or strips that whiten by bleaching your teeth. However, before you try these, keep in mind a few limitations of these kits:
How Does In-Office Teeth Whitening Work?
In-office teeth whitening procedure uses a formula containing hydrogen peroxide, which breaks down into water and oxygen components when exposed to the air and water in your mouth. The oxygen molecules then break stains into smaller pieces, which makes the colour less concentrated and your teeth brighter.
Some people may experience tooth sensitivity from whitening procedures. This happens when the peroxide in the whitener gets through the enamel to the soft layer of dentin and irritates the nerve of your tooth. In most cases, the sensitivity is temporary. Make sure to follow the directions of OTC whitening products and/or talk to your dentist for guidance.
The results from professional teeth whitening can last for as long as a year depending on your diet and lifestyle. With touch-up treatments (at home) every few months, your results can last even longer. "Touch-ups" are especially useful for patients who regularly drink beverages that can stain teeth, including coffee, tea and red wine.
Be sure to talk to one of your dentists about professional teeth whitening as well as OTC whitening products. Together, we can compare treatments and determine which solution will be most effective for you. Contact us today to schedule a consultation appointment!
