Tooth whitening is one of the most popular procedures of aesthetic dentistry, because it can greatly improve how your teeth look. Teeth naturally darken with age and their appearance can be affected by the accumulation of surface stains acquired from the use of tobacco products and the consumption of certain foods or drinks. Tooth whitening lightens teeth and helps to remove stains and discoloration. If applied properly, it doesn’t damage your teeth and you have much cleaner, white and eye-catching smile, and most importantly the original dental integrity is completely preserved.
Tooth whiteness provided by brushing teeth twice a day and cleaning done by regular dentist checks is sufficient for some people. But, of course everyone wants to have a whiter and more striking smile. No matter how well you look at your teeth, serious color changes will occur over the years. There can be many reasons for discoloration. Thinning of the enamel depending on age, consumption of coffee or tea, smoking, high doses of fluoride, tetracycline group antibiotics, and discolorations caused by root canal treatments are the most common reasons.
Whitening should be done only under a dentist’s supervision. It might not be suitable for every person. Bleaching is not recommended in children under the age of 15, in pregnant or lactating women, in individuals with sensitive teeth and gums, receding gums and/or defective restorations, and in individuals with gum disease or teeth with worn enamel. Teeth whitening is ideal for patients who have healthy, unrestored teeth (no fillings) and healthy gums who would like a brighter smile. Before the whitening procedure, it is absolutely necessary to go through the control of your esthetic dentist and determine whether you are a suitable candidate.
There are two types of tooth bleaching as office bleaching and home bleaching;
In home bleaching, a specific dental tray is molded based on patient’s measurement and patient uses this tray and bleaching material at home as instructed by dentist. Home bleaching has the following advantages over other types of treatment:
- You spend very little time at the dentist.
- It is usually much more financially affordable.
- You are able to bleach your teeth at your own convenience.
In office bleaching, soft tissue isolations are used at clinical conditions to bleach teeth. Unlike home-use systems that incorporate low-dose bleaching agents, in-office bleaching takes place under carefully monitored conditions which allow for the safe, controlled, pain-free use of a relatively high concentration of bleaching gel with yielding results that are visible immediately.
Combined bleaching or combination of two methods is used in some patients to get better and more permanent outcomes. For bleaching procedure, dental structure and personal habits play significant role in bleaching degree and permanence of the outcome.
