Teeth Whitening:What Works


Teeth whitening can be a very effective way of lightening the natural colour of your teeth.Teeth whitening seems to be the  dominating our Instagram and Facebook feeds .We need to look into the reasons ,why your teeth appear yellow before we discuss the various  teeth whitening treatments available.

Why are my Teeth Yellow?

    1. You get yellow teeth from smoking

Smokers are prone to yellower teeth.Smoking causes yellow teeth because of the tar, nicotine and other chemicals carried in the smoke. These seep into the pores in your tooth enamel, staining its natural colour.

    2. Slack oral hygiene causes yellow stains

If you notice a yellow buildup on your teeth, it’s probably plaque or tartar. Plaque forms when bacteria from food and drink particles aren’t cleaned properly from your teeth. Over time, plaque hardens to form tartar, which can only be removed by a dentist or hygienist.

   3. Foods that make your teeth yellow

It shouldn’t come as a big surprise that the things you put into your mouth have an effect on the colour of your teeth. If your teeth are stained yellow, it might be because of foods such as :Red Wine,Curry,Coffee/Tea,Berries,Soy Sauce,Balsamic vinegar

  4. Age

It is natural for your teeth to become yellow as you age. This is because the protective enamel layer becomes thinner, revealing more of the yellow dentin underneath.

  5. Medication

Some antibiotics such as tetracycline  can affect the colour of teeth. Speak to your doctor if you’re concerned about this.

  6. Diseases that cause yellow teeth

Some illnesses might cause yellow stains or discoloured teeth, particularly those that affect the liver. Patients who undergo chemotherapy or radiation treatment for cancer may also find their teeth turning brownish hue.

Does any of the available Teeth Whitening Products actually work?Lets look into the different treatment options.

 1)In-chair whitening/Laser Whitening/Zoom Whitening

  This needs to be done at the dentist.The appointment usually takes about 2 hours . Zoom whitening is an accelerated teeth whitening procedure. After a thorough teeth cleaning, a powerful bleaching agent created from concentrated peroxide is applied to the yellow or stained teeth. The strong dental gel is allowed to cure under the Zoom light. During this curing time, the bleaching gel slowly dissolves stains  that are attached to the teeth contributing to the yellowing or staining. If teeth are sensitive after the procedure, a special fluoride paste can be applied to reduce sensitivity. The advantage of in-chair whitening is that the results are pretty much instant.

2) Home Whitening

We use Boutique Whitening which is a premium quality whitening gel that delivers superior results, with a noticeable improvement in just a few days.Home Whitening is done using custom made trays that are customised to fit your mouth and these trays can hold the whitening gel. The patient takes home his or her tray and wears it either every night or every day for two weeks.Home teeth whitening is the most popular way and it does achieve very good results.

 3) Over-the-counter products

  Whitening Strips

 Example of a popular over-the-counter gel you can buy is Crest Whitening Strips .You can buy these over the counter in chemists and supermarkets, and basically it’s like a little adhesive you stick onto your teeth with the peroxide gel inside the adhesive. , It’s probably not as good because it doesn’t have the customised trays, which means it’s not customised to fit people’s teeth. The concentration of the active whitening ingredient is too low to have good end results.

 Whitening Toothpaste

There are several whitening toothpastes on the market. Although they do not affect the natural colour of your teeth, they may be effective at removing staining. Therefore, they may improve the overall appearance of your teeth. Toothpaste like smokers toothpaste are a bit abrasive and may cause damage to your enamel.

Whitening done at my Beautician 

In UK teeth whitening can only legally be carried out by a dentist. So tooth whitening by beauticians is illegal. In Europe, it is illegal to supply bleaching material containing more than 0.1% peroxide (or the equivalent in carbamide peroxide) to anyone other than a dentist, or direct to the public.These regulations are to protect the public. They make sure that anyone carrying out whitening is properly trained and has the right skills and knowledge to carry out the procedure without risking permanent damage to the teeth or gums.

How long will my teeth stay whiter?

The effects of whitening are thought to last up to three years. However, this will vary from person to person. The effect is less likely to last as long if you smoke, or eat or drink products that can stain your teeth. Ask your dental team for their opinion before you start the treatment.

Any Side Effects ?


About 10 percent of people who undergo teeth whitening may find that their teeth becomes sensitive to cold during or after the treatment. Others may have discomfort in the gums, a sore throat or white patches on the gum line. These symptoms are usually temporary . Once the whitening treatment stops, the sensitivity should stop too
