A smile is one of the simplest gestures that we can make, but it can also be one of the biggest. A bright smile is considered a reflection of friendliness, honesty, happiness, and health.
An attractive smile can be beneficial in social situations, help attract a partner and also make you more confident and outgoing. We are bombarded with pictures of celebrities flashing mega-watt grins, which unfortunately cause many people to feel self-conscious about their own smile.
The enamel covering the teeth can become stained over time for a number of reasons. The fix for this is teeth whitening, which is considered to be one of the easiest and most economical ways of enhancing the appeal of your smile.
REASONS FOR TOOTH DISCOLORATION
White teeth are universally considered to be more youthful due to the fact that infant/first teeth are almost always whiter than their adult counterparts.
Adult teeth can become stained or discolored over time due to:
Smoking – one of the biggest contributors to yellowed teeth!
The use of antibiotics as a child/teenager
Exposure to high levels of fluoride
Food or drinks that contain tannins such as oranges,
carrots, red wine, and coffee
Trauma to the tooth
Damage to nerve or blood vessels inside the root canal
Genetics – the thickness of the enamel covering your teeth is usually determined by genetics. Thinner enamel can often show the color of the dentin beneath it, giving the tooth a darker appearance.
Aging – our teeth naturally darken as we get older
CAN’T I JUST USE AN OVER-THE-COUNTER TEETH WHITENER?
There are dozens of products on the market that claim to be able to improve the whiteness of your smile without you needing to visit the dentist. However, over the counter products are simply not able to provide the same strength of whitening as professional-grade treatments that your dentist is able to offer. Not only are the results usually only mediocre, but they also fade quicker and usually require more treatments.
We recommend that you at least have the first treatment performed by a dentist who is qualified in providing teeth whitening procedures.
THE IN-OFFICE WHITENING PROCEDURE
Dental whitening is a painless procedure, but one that may require several visits to your dentist in order to achieve the final color results you desire. During your consultation visit, your dentist will likely photograph your teeth to provide a starting point for comparison so that he/she can effectively monitor the progress of your treatment. Your dentist will then perform a thorough examination to ensure that no other treatment is required ahead of the whitening process as well as ask you a number of questions to get to the cause of the discoloration.
Next, your dentist or dental hygienist will give your teeth a thorough cleaning to remove any residue or bacteria that may prevent the whitening process from working properly.
After this, it is time for the whitening to begin. There are two main types of tooth whitening performed in most offices.
The most common variety of teeth whitening is called vital whitening which is performed on teeth with current active nerves and involves whitening the tooth on the outside only.
The whitening product is usually a gel that contains a form of hydrogen peroxide and is applied directly on to the surface of the tooth.
Your dentist will then shine a special laser or light onto your teeth, creating a chemical reaction that begins the bleaching.
You can expect a session of vital whitening to take between 30 and 90 minutes. Then depending on the extent of your staining as well as the level of whiteness you wish to achieve, you may require between one and three visits to your dentist’s office.
Non-vital whitening is most commonly used in teeth that are stained from the inside out, usually as a result of damage to the interior nerves.
In non-vital whitening, your dentist will place the whitening agent inside the tooth and cover it with a temporary filling. Again, you may require multiple treatments in order to achieve the extent of whitening that you desire.
RISKS OF TEETH WHITENING
Teeth whitening is a very safe procedure and is unlikely to cause serious side effects. However, you may find that your gums and teeth are a little more sensitive for a short time after the procedure. Even though this is a relatively safe procedure, not enough is known about the effect of teeth whitening on unborn babies, and as such, pregnant women should refrain from having their teeth whitened until after delivery.
LONGEVITY OF RESULTS
Unfortunately, teeth whitening is not a one-off procedure, but the speed with which the whiteness will fade will vary depending on a range of factors including whether or not you smoke and if you consume a lot of stain-causing foods and drinks. If these are regular habits for you, then you could see the whiteness begin to fade in as little as six weeks after your procedure. However, if you avoid stain-inducing activities and maintain a rigorous oral care regime, then you may not require another teeth whitening procedure for six to twelve months after your initial treatment.
