Smile is the first thing we notice about a person and more than anything else, it reveals the teeth first. We all desire for that set of perfectly aligned teeth that are pearly white in colour. However, this is not a reality for all people.
Due to various reasons, our teeth are not always bright and white. In some cases, the high fluoride content in the water can lead to fluorosis, which causes irregular patches on the teeth. Chewing tobacco and smoking are other reasons for teeth discolouration, ranging from yellow to brown and then to black. The most inevitable reason is ageing, where they naturally change to a darker shade of yellow. However, dental technology has improved to come up with various solutions, so that the dream for the set of pearly white teeth can be made a reality.
Bleaching is by far the most commonly used method for teeth whitening. The tooth has an outer layer called enamel, a middle layer called dentin, and a final inner layer called the pulp. The enamel contains organic particles that give the tooth its colour and the bleaching material attacks these organic particles and removes the stains.
It is always advisable to use teeth bleach under the supervision of a dentist. A thorough examination is required before deciding for one of the two modes of bleaching.
The two modes of bleaching are mentioned below:
In addition, for minor discolourations, there are other options as below:
But there are also a few side effects of bleaching. Sensitivity and gum irritation are the two common shortcomings of bleaching. This could be either from the chemical or the trays that are used. The need to repeat the treatment is another shortcoming. Repeated visits to the dentist may be needed once or twice a year to maintain the pearly white smile!
