Teeth Whitening

Why would my teeth need to be whitened?

Teeth yellow with age and can become stained on the surface through daily exposure to foods and drinks such as tea, coffee and blackcurrants. Calculus or tartar can also affect the colouration of the teeth. Some people may have internal staining which can be caused by certain antibiotics or minute cracks in the teeth. One of the ways to restore your bright smile is by doing teeth whitening.

Is dental whitening for you?

Naturally, prior to any treatment, a thorough examination and diagnosis should be performed, evaluating the potential benefits the technique may offer you. Teeth that have become stained from age, coffee, tea or smoking are ideal candidates. Patients with healthy, natural and unfilled teeth often achieve dazzling results. Teeth darkened with extrinsic or surface stains, respond better to bleaching than deep, intrinsic discoloration caused by fluoride or tetracycline. These types of stain are less likely to produce dramatic results. Bleaching is generally not indicated for sensitive or worn teeth; those with large fillings or crowns; and teeth affected by gum disease.

Teeth Whitening Options

In-office Teeth Whitening

In-office Teeth Whitening offers good results. This procedure takes just over an hour. It is more costly. However, the time you can save by having immediate results makes this option appealing. A protective gel layer is placed on your gums adjacent to the teeth and hardened. Then the whitening gel is applied on your teeth.

Teeth Whitening Home Kits

Dental Whitening Home Kits take longer to achieve the desired results than in-office bleaching but they are more convenient in terms of time and more cost-effective.  Teeth-Whitening Gel (about a third of a tube) is applied on the tray according to the dentist instructions. After placing in the mouth, any excess gel which has flowed out should be wiped away gently. Depending on the concentration of the gel, these clear trays are usually worn a couple of hours a day or overnight. It usually takes a couple of weeks before results are noticeable.

For both In-office and Home Kit Whitening, certain food that can cause stains easily (eg. red wine, tomato sauce) have to be avoided for the duration of the whitening.

Teeth Whitening Procedure

Teeth whitening is a procedure to lighten the natural colour of your teeth without removing any of the tooth surfaces. The two most common methods are In-office Teeth Whitening and using teeth whitening trays and gels.

In-office Teeth Whitening offers excellent results. This procedure is performed in the dental clinic in just over an hour. It is more costly but the time you save by having immediate results makes this option appealing.

Dental whitening home kits take longer to achieve the desired results than in-office bleaching but they are more convenient time-wise and cost-effective. Depending on the strength of peroxide in the gel, these clear trays are usually worn a couple of hours a day or overnight and could take anywhere from 3 days to a couple of weeks before results are noticeable.

Dental whitening kits from the dentist produce faster and more effective results because they contain a stronger peroxide-bleaching agent than whitening kits purchased over the counter.

Another benefit of trays and gels from the dentist is that the trays are custom made, and fit your teeth exactly so that the gums are protected from the tooth whitening gels.

Frequently Asked Questions

What about store/pharmacy bought products?

Over-the-counter kits are not recommended as they contain only a small concentration of hydrogen peroxide, which reduces the effectiveness of the product. Some also contain mild acids, while others are abrasive.

Although these products are cheaper, whitening is a complicated treatment procedure and should only be carried out by a dentist after thorough examination and assessment of your teeth. It is very important to follow the instructions issued by your dentist and to ensure that you attend any follow-up appointments recommended.

Will teeth whitening harm my teeth?

To our knowledge, nothing detrimental has been documented and microscopic research shows no changes to the tooth surface with the use of 10% bleaching solution. There is no study that we have come across showing any irreversible damage to the tooth structure.

If my teeth are sensitive during teeth whitening, what can I do?

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?

Generally, immediately after whitening, the colour will fade slightly and then remain stable for approximately 2 years, sometimes longer.

Touch-ups every 4-6 months with 1-2 applications are recommended to maintain your desired shade.

The success of teeth whitening depends on several factors:

  • The cause of discolouration
  • How long have the teeth been discoloured
  • The location of discolouration
  • How long can the whitening gel remain at the affected site
