Bleaching North York

In most cases, the natural colour of teeth is within a range of light greyish-yellow shades. Teeth naturally darken with age and their appearance can be affected by the accumulation of surface stains acquired from the use of tobacco products and the consumption of certain foods or drinks.

In addition, the perception of the colour of teeth is severely affected by skin tone and make-up. Independent of the real colour of their teeth, people with darker skin or who use dark makeup will look like they have brighter teeth.

Although teeth are not naturally meant to be completely white, many Canadians want a brighter smile. Responding to this desire, a wide range of "whitening" options has become available to consumers. These products fall into two main categories: surface whiteners and bleaches.

It should be noted that claims related to tooth whitening are seen as cosmetic in nature by Health Canada. These claims must be accurate, so as not to mislead the public. However, the regulator tolerates some puffery or exaggeration. As a consequence, the results of whitening treatment may not be as convincing as consumers originally expected.

Most bleaching products are peroxide-based and are actually capable of altering the colours of the tooth itself. However, not all tooth discolourations respond to tooth-bleaching treatments. Individuals contemplating tooth-bleaching should consult with Dr. Nubia Díaz to determine the cause of the tooth discolouration and to determine whether a bleaching treatment will have the desired result. This step is especially important for patients with fillings, root canal treatments, crowns and/or with extremely dark stains on the anterior teeth.

Bleaching should be done only under Dr. Nubia Díaz's care. Tooth-bleaching under controlled dental office conditions may be safe and effective, but the new in-office vital tooth-bleaching techniques, particularly those using laser and lights, have undergone little scientific assessment.

Home-use tooth-bleaching systems are available to the general public, either from Dr. Nubia Díaz or from various retail outlets. Clinical studies support the safety and effectiveness of home-use bleaching gels when used appropriately. Tooth sensitivity and irritation to soft tissues can occur during bleaching treatment, but these effects are transient. Yet the effects of long-term tooth-bleaching are unknown and need to be researched, especially since the effect is not permanent and many individuals end up undergoing periodic bleaching treatments.
