What is teeth whitening?

Tooth whitening is the removal of stains and discolorations from the enamel and dentin. The outer layer of the tooth is enamel, and beneath the enamel is dentin. Enamel is thin and typically much lighter in colour, while dentin is darker in colour and makes up the bulk of the tooth. Enamel can be discoloured over time simply from age, but also from outside sources like coffee, tea, tobacco, and other foods and beverages. Also, as we age, our enamel thins, causing more dentin to show through, making the overall appearance of the tooth look darker. Whitening your teeth removes these stains and discolorations, giving you a whiter, brighter smile.

How does teeth whitening work?

Working from the inside out, the active ingredients in EU compliant gels used in City Smile penetrate your teeth to break down the discoloured molecules deep down in your teeth, removing stains and whitening your smile. EU compliant non-peroxide gels contain sodium perborate or sodium bicarbonate making the treatment pain free.

Is the non-peroxide teeth whitening gel effective?

The non-peroxide whitening solutions are on the market for 3 years. They were introduced in Ireland due to the new EU regulations (from 2012). Before the only option for whitening was either hydrogen peroxide or carbamide peroxide base gel. They were very effective but unfortunately have a lot of side effects like sensitivity, dehydration or chemical burn.

The non-peroxide gels used in City Smile are virtually as effective as the peroxide-based but without the potential downside danger of sore throat, chemical burning of the gums, or increased sensitivity of the teeth and can be used with home whitening treys but also works very well with UV light-free laser accelerator lamps.

How long does it take?

1 full hour of laser treatment (usually divided into 2 x 30 mins or 3 x 20 mins sessions all done in 1 day).

Why Whiten Teeth?

Your smile can create a massive difference to your confidence and self esteem. As we get older our teeth naturally darken and this can be affected by various factors, however this process can be accelerated with staining foods and drinks. Over time you may feel that your teeth are not as light as they used to be.

How white will my teeth go at the end of the treatment?

This depends on a number of factors and results will vary between patients. Generally speaking, we will get your teeth to as white as your teeth can naturally go. We expect an improvement of 2-10 shades from a treatment. We take an initial shade of your teeth to show the difference at the end of treatment.

How soon will I see results?

Some people get the result they want after 1 session, while most people see results from the whitening procedure within a couple of days.

Will the teeth remain permanently white?

Teeth whitening results are very stable, leaving you with a stunning smile long after treatment is over. However, there are a few factors that can make teeth lose their brightness. Things like genetics, diet, age, some medications (like tetracycline), and certain habits (like smoking) may affect the length of your whitening results. Fortunately, touch-up treatments are quick and easy, helping you get that bright, white smile back. Results will generally last for up to 1 year, sometimes longer

Will the gel whiten crowns, veneers or false teeth?

No. The procedure will only remove staining from natural teeth.

If you are planning to have a crown, bridge, filling or false tooth, it is recommended that you first have your teeth whitened. We can then match the shade to your new colour.

After Care & Tips

To get the best results from having your teeth whitened, we recommend the following:

During whitening, try avoid staining foods and drinks like red wine, tea, coffee, tomato based sauces, curry based sauces etc. If it would stain your clothes then it may stain your teeth

Avoid Smoking

Why do some People have Yellow Teeth?

There are many factors affecting the colour of your teeth. One of the most important factors affecting the colour of your teeth is actually your genes. If your mother and father have naturally yellow teeth, then chances are that you will have a similar teeth colour.

Causes of Yellow Teeth

Among the primary reasons of yellow teeth (aside from your genes) are food, oral hygiene, and aging. Most of everyday food that we consume contains chromomeric ingredients that are used by manufactures to impart colouring. Food and drinks such as tea, coffee, wine, and certain fruits like berries contain colour impurities which stain white teeth. Smokers should also be aware of the fact that tobacco is not only harmful but cause permanent discoloration. Secondly, poor dental hygiene is another major cause of concern. For adults, medical experts suggest using a combination of brushing and floss to remove plaque that may reside between tooth cavities. Besides these medical reasons, often times the cause is natural. For example, as someone grows old, the upper layer of enamel wears down exposing the yellow colour of the underlying dentin layer. Certain diseases which require chemotherapy or exposure to radiation may also cause enamel layer to decay, overtimes. Excessive fluoride contamination can be a source of discoloration. Meanwhile antibiotics like Tetracycline are widely presumed to discolour teeth. Accidents at a young age may also explain permanent yellow teeth.

Which teeth shades are easier to whiten?

In general if your teeth are yellow, it will be easier to make them whiter. Gray teeth are harder to whiten. The easiest way to find out what to expect from teeth whitening is to talk to City Smile specialists. Some people have teeth that are naturally yellow (the yellow colour is not result of stains) and in their case it will be harder to whiten their teeth considerably.

Gray teeth shade is increased by minerals and fluoride found in local water and may now be targeted by contemporary whitening strategies including a laser teeth whitening and take home kit that can be applied routinely.
