1. What is teeth whitening?
Teeth whitening is a process that whitens the teeth. The procedure does not harm the structure of the enamel of the tooth. Dentists whiten the teeth by using certain teeth-whitening chemicals or removing the stains from the teeth.
2. What are the factors that can change the colour of your teeth?
Cracks in teeth that develop stains, smoking, and consuming beverages and foods that can stain, for example, tea, red wine and coffee are some factors that cause teeth discolouration. Other factors include old age, antibiotics, and presence of tartar in the teeth.
3. Which method is used for teeth whitening?
Among all the methods, dentists typically use the bleaching method to whiten teeth. The active ingredient in the chemicals used for this process is mostly either carbamide peroxide or hydrogen peroxide. The bleaching agents oxidise the stain, which leads to a lighter tooth colour.
4. How long will my teeth stay white with this procedure?
In most cases, effects of bleaching last for up to 3 years. You can sustain the bleaching effect for about 3 years by avoiding smoking, consuming foods that increase the possibility of staining in your teeth like drinking red wine.
5. What are the side-effects of teeth whitening?
Sore throat, sensitivity to cold foods during or after treatment, irritated gums, and white patches in the gums are some of the common side effects people experience after bleaching their teeth. Most side effects of teeth whitening subside in a few days. If they do not reduce in some days, contact your doctor.
