Surface Whiteners Contents

For the average person, natural tooth colour ranges from light grey to light yellow shades. Over time and with exposure to certain foods, beverages, and habits such as coffee, alcohol, and tobacco, the colour of your teeth may darken. It is perfectly normal for surface stains to build up on your teeth to diminish your bright smile. In addition, the colour of your teeth is something a matter of perception. Those with darker skin tones and makeup will appear to have brighter teeth, regardless of the actual colour of these teeth.

And while teeth are not naturally pure white, many dental patients complain of a dull, lackluster smile. Fortunately, teeth whitening is a common and safe procedure that can restore the quality of your smile. There are two main methods of tooth whitening: surface whiteners and bleaches. Surface whiteners contain abrasives that remove surface stains and leave your teeth whiter than before. Most surface whiteners fall into the category of toothpaste, gels, or chewing gums.

The abrasives in these surface whiteners are usually finer versions of the abrasives found in regular toothpaste so excessive wear on your teeth is not usually a concern when you use these products. Nevertheless, the degree of whitening is somewhat limited, and if you have found little benefit from these products, you should consider seeking a dentist's advice.
