Cosmetic Dentistry and Bleaching

Cosmetic dentistry is that branch of dentistry dedicated to improving one's appearance. Aesthetic dentistry may range from simply replacing a discoloured front filling or a 'silver' back filling into a white filling that looks better at one end, to bleaching and/or veneers in combination, to completely transform a smile.

Veneers are thin laminates of porcelain that stick to the front teeth. they are usually very thin, less than 0.5mm, and are especially made to be highly aesthetic. They have numerous advantages over crowns and tradidtional white fillings, namely in being translucent (thus making them look natural as well as very aesthetic), and in that they do not need extensive reduction of the original tooth (thereby preserving much of the original shape and size of the tooth).

Full porcelain crowns are the modern alternative to traditional metal-porcelain crowns. The latter crowns consist of a metal underlay that gives strength to the crown and a porcelain onlay that makes the crown look white. Unfortunatley however, after a few years, the metal underlay starts to 'shine through', resulting in a greying of the margin, which looks unaesthetic on front teeth. Modern porcelains are made using special techniques that are very strong even in the thinnest sections and so do not require metal underlays. A wide range of shades of porcelain is available, enabling a close match to the most particular shade of neighbouring teeth or the choice of a new shade made to our patients' satisfaction.

Bleaching (tooth whitening) is one of the latest innovations to be used in aesthetic dentistry. It works by way of the bleach infiltrating tooth tissue and breaking down darker substances into tinier, lighter substances, thereby improving the overall appearance. It is not harmful to the teeth, and subject to proper usage, it is not expected to give any unpleasant side-effects. The only problem that has been identified is one of possible sensitivity of the teeth following bleaching, that occurs in an unspecified percentage of cases. To counter this possible sensitivity, the use of a sensitive toothpaste or a product called ‘Tooth Mousse’, readily available at chemists, is advocated.

Bleaching is most effective in cases where the teeth are yellowish or orangey in colour, and one would realistically expect a 7-step shade reduction after a course of bleaching. Porcelain-white teeth are not a realistic expectation, and belong only to movie stars. Your dentist will be able to guide you better as to whether bleaching would be effective to its full potential. Bleaching cannot be undergone by pregnant or breastfeeding ladies, or to people who have an allergy to certain components of the bleach.

In-surgery bleaching may make use of a light to make the bleaching process shorter (about 1 hour), but the disadvantage is that this is more likeley to cause unpleasant sensitivity after. Take home bleaching is the easiest and most versatile bleaching technique, and is done in the comfort of one's home typically for one hour a day for 3 weeks, and acheives the same result as the in surgery technique.


The Take-Home Bleaching Syringes


In the latter procedure, bleach gel is usually loaded onto special custom-made trays which fit tightly around one's teeth and have a reservoir area to house bleach. Below is an outline of the method used to bleach teeth un the take-home technique.

Casts and trays

The Custom-made Bleaching Tray and Cast


1. Brush your teeth well, and floss,

2. Load the bleach onto the trays and remove any excess bleach from around the gum margins using cotton wool or tissue-paper,

3. Bleach the teeth for about one hour at a stretch. Do not eat or drink anything or smoke during this period and for at least one hour after. It might be handy to bleach just before bedtime, as stains are more likely to stick to the teeth just after they have been bleached.



Bleach the Teeth for an Hour


4. Brush the teeth immediately after the bleaching hour is up, clean the bleaching trays, and store in a cool place, such as a refrigerator.

There will be a certain element of regression of the shade of the teeth in the first few days, and bleaching may need to be touched-up every nine months or so to maintain the new lighter colouration, but of course this is done at the discretion of the patient. Some people may be quite happy to have a lighter shade for a special occasion, such as a wedding.

Recent Government guidelines have stated that tooth whitening cannot be done using bleaching agents for cosmetic reasons, but it may be used at the discretion of a dental surgeon for medical purposes. As such your treatment would be considered as being ‘medical’, on the grounds that it is intended to improve your quality of life by improving your perceived ‘self-image’, and by being a non-destructive way of improving the appearance of your teeth, as opposed to say, crowns.
