Frequently Asked Questions About Teeth Whitening

I brush my teeth regularly, do I need professional teeth whitening at a dental clinic?

Do you still see yellowish colour or stains on your teeth? This is why teeth whitening is required Regular brushing will keep your teeth clean and healthy, but it will not get the stains out of your teeth or take away discolouration. There are two types of stains that discolour your teeth, external stains and internal stains.

External stains: Frequent consumption of coloured foods like coffee, tea, cola, or red wine, excessive smoking, dental plaque or use of products high in fluoride can stain your outer layer of teeth (enamel surface).

Internal Discolouration: The inner layer of your teeth (yellow dentine) can get stained due to ageing, antibiotics used when young, discolouration from birth (genetic factors) or due to dental trauma (bleeding teeth). These give your teeth a yellowish or greyish hue. Regular brushing may help to some extent in terms of taking away external stains but they do not remove internal discolouration. After a thorough examination and diagnosis, our dental clinic will advise you on an effective whitening procedure to lighten the shade of your teeth’s colour and make sure all stains are removed. While maintaining a good oral hygiene through regular brushing, teeth whitening is an ideal method to gain a whiter smile!

I also use whitening toothpaste. Why do I need professional teeth whitening at a dental clinic?

One of the most popular questions but least overlooked. In simple terms with whitening toothpaste your teeth will be clean and most probably shiny, but still may look yellow and stained. There are two different types of teeth discolouration – Internal and external

External stains: Due to frequent intake of coloured foods like coffee, tea, cola, or red wine, excessive smoking, dental plaque or use of products high in fluoride can stain your outer layer of teeth (enamel surface).

Internal Discolouration: The stain is at the inner layer of the teeth (yellow dentine). These stains give your teeth a yellowish or greyish hue. Attributed to ageing, antibiotics used when young, discolouration from birth (genetic factors) or due to dental trauma (bleeding teeth) Whitening toothpaste is mainly a cleaning agent and can remove external stains to a certain extent. They do not remove internal discolouration. At Smilepoint we conduct a thorough examination and diagnosis will be performed by an expert dentist, and a safe and effective whitening procedure will be adopted to make sure all stains are removed. This is an effective and sure way to achieve a whiter smile!

What about those over-the-counter teeth whitening kits? Surely those must be effective?

It is only 11.99 at an Online Store! But one issue. Teeth whitening requires an active ingredient to whiten your teeth and by law over-the-counter teeth whitening kits have a restriction by the Ministry of Health (MOH) for the concentration to be 0.1% or less.

Dental clinics employ teeth whitening agents up to 10% and our expert dentists will assess your condition case by case and apply the required level in a safe and effective manner to target both internal and external stains So it is kind of self-explanatory which method is effective. Hence, over-the-counter kits even though they are cheaper, the chances are lesser that they will effectively whiten your teeth. Teeth whitening is a complicated treatment procedure that should only be carried out by a dentist after a thorough examination and assessment of your teeth and gums.

Why a dental clinic for teeth whitening? What about Spa and Saloons?

Spas and saloons seem affordable and Sensible, right? All done in one place and we sure love to have a good bargain, but again the same restriction applies to them for teeth whitening as non-dentists. The Ministry of Health (MOH) has restricted the use of active agents in teeth whitening concentration to 0.1% or less.

A non-medical professional will only allow a low or ineffective amount of whitening agent and will not make your teeth as white as you expected. Further complications can arise due to ill preparation and can result in chemical burns and excessive bleaching This does not mean the most expensive teeth whitening solution should be chosen, but cost and convenience should not be the only guiding factor. At Smilepoint we have a range of teeth whitening packages that will effectively and safely bring you the smile you always dreamed of at a reasonable cost and most importantly desired results!

Will Teeth Whitening harm my teeth?

Current research shows no changes to the tooth surface or tooth structure with the use of 10% bleaching gel. Our experienced and professional dentists will always assess your condition before beginning any treatment, so you can be sure that you are in good hands.

What can I do if my teeth are sensitive during Teeth Whitening?

Toothpaste containing Potassium Nitrate or a prescription level of Fluoride can help seal the microscopic tubules (dentin pores) to prevent nerve irritation and sensitivity. There are also professional products available that your dentist can apply to the affected area.

How long does Teeth Whitening last?

It’s important to have realistic expectations of before and after whitening. Generally, immediately after teeth whitening, the colour will fade very slightly. This may remain stable for approximately 2 years, sometimes longer. However, several factors such as your diet and habits (eg. smoking) can cause staining to occur again. We recommend patients to get touch-ups every 3-6 months to maintain your desired shade.
