Women rate a man’s smile as their most important feature. Teeth are thought to be the male equivalent of a peacock’s tail - a sign of a healthy lifestyle and desirable genetics.
Correspondingly, yellow teeth can look unappealing, and can cost you your confidence and make you less likely to smile.
Luckily, improving the colouration of your teeth can be as simple as changing what you eat and drink, polishing your oral care routine, and using our highly effective teeth whitening kits which can give your teeth an extra whitening boost in an easy, convenient and safe way.
Understanding whitening begins with understanding tooth staining. There are two sources of tooth discolouration: intrinsic stains and extrinsic stains.
With intrinsic stains, teeth become yellow due to a thinning of enamel which allows the dentin underneath it to show through. Dentin is the hard, inner surface of the tooth which supports the enamel. It a yellow/brownish in colour.
Dentin is one of the four major components of teeth along with the enamel, as well as cementum and pulp. It is usually covered by enamel on the crown and cementum on the root and surrounds the entire pulp.
Intrinsic stains are often difficult to remove as they become part of the tooth. They can be caused by a variety of factors including poor oral hygiene, aging, the side-effects of certain medication, excessive fluoride use, as well as trauma.
Poor oral hygiene is a leading cause of discolouration. We all have bacteria in our mouth which if not brushed away can form plaque and tartar. The plaque and tartar bacteria eat sugar in the mouth and produce acids which weaken and decay the enamel. This allows the dentin to show through.
Aging is a natural cause of discolouration. Aging causes teeth to yellow as the enamel degrades and thins over time, allowing the dentin to show through.
A variety of common and bespoke medication can cause discoloration too. These include antihistamines, antipsychotics and blood pressure treatments, as well as mouthwash for treating gum inflammation (containing chlorhexidine), and acne treatments (e.g. minocycline).
Fluoride can be good for teeth by strengthening the enamel and preventing decay but too much of it can cause discolouration. It's possible to get too much fluoride by taking supplements or regularly using rinses and toothpastes with fluoride in it.
Finally, genetics will also play a part, as genes are responsible for a variety of factors that determine whitening or discolouration. These include the strength and thickness of tooth enamel and how it responds to acids produced by bacteria in the mouth.
Extrinsic stains happen on the surface of the enamel. Although tooth enamel can be easily stained, these stains can typically be removed or corrected.
Generally, any food or drink that can stain clothes can also stain your teeth. Dark-coloured foods including chocolate, curries, and even fruit such as grapes, blueberries and cherries are leading causes of straining.
As for drink, it’s the usual suspects; coffee and red wine. Both contain ingredients called tannins, which cause colour compounds to stick to your teeth. When these compounds stick, they can leave an unwanted yellow hue behind.
Smoking is another leading cause of discolouration. This is because the tar and nicotine in tabacco are absorbed into the microscopic pores in tooth enamel, causing a yellow or brown discolouration, which becomes darker darker and harder to remove over time (nicotine is colourless but turns yellow when combined with oxygen).
