How Teeth Whitening in North York Works
We have consistently been asked about different teeth whitening options, especially with the ocean of products available to the public. Reasonably so, patients have asked us about the benefits and dangers, the risk of sensitivity, the chance that the enamel may thin, and how long the results will last. Since teeth whitening in North York is in such high demand, it is important to get all questions answered so the right method of whitening can be selected.
1. What is tooth discoloration caused by?
Tooth discoloration occurs from many sources and reasons. Dietary and lifestyle choices are one of the most common causes of yellowing of teeth. Dark colored food and drink products, such as blueberries, soy sauce, Pepsi, tea and coffee, are major contributors. All of these food products exhibit the chemical molecules called, chromogens, which the molecular cause of discoloration. The constant contact of your dentition with these staining-prone food will cause yellowing of the enamel surface. Smoking is another prevalent source of darkening teeth. Teeth that have become grayer in colour is mostly attributed to a phenomena known as “tetracycline staining.” More common in countries abroad, when patients are given an antibiotic known as tetracycline as a child to fight common infections, discoloration of the teeth can occur. Persistant use of this antibiotic can worsen the condition, while also causing streaking. Below is an example of a patient with tetracycline stains.
2. How does teeth whitening work?
Teeth whitening in North York is a great method to brighten a smile. As described previously, chromogen molecules penetrate deep into the tooth surface, causing discoloration. It is these molecules which need to be broken down to remove the staining in the teeth. This is where peroxide comes into play! When applied to the teeth, the whitening materials, made up of either hydrogen peroxide or carbomide peroxide, breaks down to free radicals which helps to disrupt the chemical bonds of chromogen. This breakdown of chromogen, in effect, leaves the tooth in its natural whitened state! Tetracycline stained teeth, however, are more difficult to get the desired result. Often other solutions, such as veneers or crowns are required to permanently restore the tooth to its natural colour.
3. Which teeth whitening product should I use?
There are many teeth whitening in North York options available to the public. Over-the-counter products, such as Crest White Strips, have gain a lot of attention recently, due to extensive marketing as well as its low cost. When using this product, you must ensure that the strips cover all curved surfaces of the teeth. If not, teeth will be unevenly whitened. Furthermore, the concentration of peroxide is very low, so ideal whitening results may not be achievable. You must also carefully read ingredients to over-the-counter whitening products, since they are less regulated. Thinning of enamel is more prevalent with them.
Teeth whitening in North York can also be done in a dental office. With more regulations and research compared to over-the-counter products, in-office products are typically safer and more effective. Our office utilizes the Philips Zoom Whitening product. With it, patients are able to achieved their whitest teeth in a one hour session. Whether you choose an in-office product or one bought at a drug store, it is best to consult with a dentist to ensure it is a safe and widely recognized product.
