A beautiful, brilliant smile is a great asset and a dream of many of us.
Unfortunately, very often our teeth do not look like they should because of our bad habits which include smoking or drinking too much coffee or tea.
-ageing - with the passage of time, our teeth become darker as enamel wears out and absorbs colourants.
- eating habits - red wine, coffee, tea, cola, sour fruits and coloured soda erode enamel,
-certain drugs – some drugs and chemicals, e.g. tetracycline, can stain your teeth from dark grey to brown and such stains are very difficult to remove. Overexposure to fluoride can cause fluorosis which is a dental disorder characterised by white or brown patches on the tooth enamel.
Fortunately, cosmetic dentistry offers many safe methods to restore a snow-white smile, and a wide variety of products which are available to suit every pocket and timescale, are always selected to the satisfaction of our patients.
Teeth whitening removes colourants and impurities from the so called interprismatic region of the enamel. One of the most advanced and common whitening methods involves the use of a special lamp. For the most satisfactory effect, the dental practitioner chooses the exact tooth colour and presents it to the patient as an example of what can be achieved.
The treatment is always preceded by a dental assessment to rule out any contraindications.
Prior to whitening, the teeth must be healthy, with no dental plaque or tartar.
Next, liquid cofferdam is put on the gums to protect them against irritation.
The dentist will then apply a special gel to the teeth and activate it by radiation from a lamp emitting cold blue light.
The gel will remain on the teeth for about fifteen minutes and the procedure will be repeated two times. The whole treatment will not take more than 45 minutes.
It may happen that patients with stains which are particularly difficult to remove will need a greater number of treatments to achieve the desired shade.
Sometimes the treatment needs to be continued at home, which requires the use of special whitening strips.
The whitening result will vary from person to person as it depends on the type of discolouration and the state of the teeth. Prior to the treatment, your dental practitioner will always tell you what results you can expect.
Prior to the commencement of a procedure, the dentist will assess the colour of your teeth using a standard guide with 16 shades arranged from the brightest to the darkest.
Whitening can change the shade of your teeth by five to nine shades but sometimes the difference reaches even 10 to 14 shades.
A great body of research has shown that teeth whitening performed by a qualified professional is safe and will not damage your teeth.
