Teeth whitening is an extremely effective method of lightening the colour of teeth without damaging it or having to remove any portion of the surface. According to a report published in the British Dental Journal in April 2005, nearly all of whitening approaches today work, because the most significant factor in the effectiveness of any bleaching or whitening treatment is concentration of the agent and the exposure duration.
Why People Need it?
As people age, their teeth will get darker, partly due to the fact of aging, but also due to what we drink and eat, plus other individual habits like smoking. Coffee, tea, red wine, blackcurrant juice and other foods and drinks which contain strong colours could also have some effect on the general teeth colour. The teeth might also begin to darken due to the usage of specific antibiotics. Some individuals will naturally be having more of a grey shade than others, while several others might be having white spots on the teeth due to illness or ordinary tooth decay.
There are several reasons why somebody may want to have their teeth whitened. We all differ; and just like our skin and hair differs, so do our teeth. Extremely few individuals have got teeth that are brilliant-white. Tartar could also have an impact on your teeth colour. Some might be having staining beneath the enamel cover or tiny dental cracks could appear on the teeth which then take up the stains.
What Does It Involve?
The most common method of professional teeth whitening is bleaching. The dentist will first assess you to determine if tooth whitening is appropriate for your case and also inform you about available options.
Perhaps the most widespread kind of whitening is one known as ‘dentist-supervised’ tooth whitening, which is done at home. Here you get some gel trays containing special gel that are made to fit inside your mouth similar to gum-shields. You then follow a home routine given by the dentist.
Another alternative is ‘chair-side whitening’. In this case, the dentist, therapist or hygienist puts a gel or rubber shield on your gum protection. There after they apply the whitening product onto the teeth using a tray that is specially made.
In majority of the whitening products, the active ingredient is typically hydrogen carbamide peroxide measured to appropriate quantities. For instance, the US Food and Drug Administration only approves those gels which are below 6 per cent hydrogen peroxide or 16 per cent or below of carbamide peroxide. At the same time, the Scientific Committee for Consumer Protection of the EU views all gels which contain concentrations higher than these not to be safe.
What Are Possible Side Effects?
After or during the treatment, some might find that teeth have become quite sensitive to cold. Some other category of patients might experience discomfort in their gums, some sore throat or get white patches along their gum line. All these symptoms are more often than not fleeting and ought to disappear after a couple of days following treatment.
The British Dental Bleaching Society stresses that it is essential for all dental therapists and dental hygienists to undertake suitable instruction in all dental bleaching techniques so that they are able to assist in the provision of successful whitening for all their dental patients.
