If you cannot resist your morning cuppa or the lure of your evening glass of Shiraz, you probably have discoloured teeth. And if you happen to be a smoker too, there is just no way your teeth can be stain-free. Having discoloured teeth can cause psychological problems leading to avoidance of social interaction and refusal to smile or talk without covering the mouth.
Teeth can also darken with age as the enamel becomes less porous leading to a marked change in mineral structure. Even the food we eat can cause bacterial pigments to form on the teeth. Antibiotics, especially tetracycline, is also said to cause staining of teeth.
With several new and successful teeth whitening or bleaching methods, there is help at hand. You don’t have to be stuck with those dark stained or yellowy teeth any more. In some cases, a simple professional teeth cleaning by a dentist followed by regular and correct brushing at home can remove the stains.
The only person who can tell you if you need teeth whitening is your dentist. So make an appointment and get your teeth assessed professionally. The dentist will make an assessment based on several factors: dental and general health background, clinical observation of soft and hard tissues, existing dentures and other restorations, and call for x-rays if any grave irregularity is noted on examination.
There are quite a few ways in which you can get your teeth whitened:
- in-office whitening by a dentist
- at-home whitening under the guidance and supervision of a dentist
- by patient at home with over-the-counter whitening agents
- at unregistered kiosks, salons, and spas
‘Power bleaching’ done by the dentist uses light energy to speed up the whitening process. Another process used by dentists is ‘bonding’ where a thin layer of composite material is applied over the discoloured tooth and cured with a blue light. Over the counter whitening agents include bleaching gel, pen, or strips.
The safest is to get a well-qualified and trained dentist to perform the teeth whitening for you as it is an irreversible procedure. If the whitening agents are applied carelessly, it can cause harm. In spite of it being applied professionally, you still run the risk of:
- bleeding and irritation in the stomach and oesophagus (if the whitening agent is ingested.)
- severe sensitivity of teeth
- blistering and damaging of gums
- weakening of the enamel
Also, if you already have fillings, veneers, or crowns, this may not be a good idea as these cannot be whitened and you will end up with teeth of different shades!
The moment you feel the need to whiten your teeth, fix a dental appointment and get your teeth checked thoroughly. Discuss all available options with your dentist and decide on what is best for you. You will soon have the radiant smile of your dreams!
