Teeth whitening in a nutshell

Teeth whitening, also known as tooth bleaching, is a popular cosmetic dental procedure aimed at lightening the natural colour of your teeth without removing any of the tooth surfaces. It is one of the most effective ways to enhance your smile quickly and safely.

The process of teeth whitening involves using bleaching agents, typically hydrogen peroxide or carbamide peroxide, to break down stains and discolouration on the tooth surface. When applied, these agents penetrate the porous outer layer of your teeth (enamel) to reach the discoloured molecules inside your teeth’s dentin. Oxygen molecules from the whitening agent react with the discoloured molecules in your teeth, breaking the bonds that hold them together. This process causes the teeth to appear lighter and brighter, providing a significant aesthetic improvement.

Teeth whitening is particularly effective against extrinsic stains, which are those that appear on the surface of the teeth as a result of exposure to dark-coloured beverages, foods, and tobacco, as well as routine wear and tear. These stains are easier to remove and respond well to the bleaching process. Intrinsic stains, which are deeper and can be caused by medication, trauma, or different types of mineral exposure during tooth formation, are more challenging to treat and may require more advanced whitening techniques or alternative cosmetic treatments such as veneers.

Professional vs At-Home Whitening

Professional Teeth Whitening

Professional teeth whitening, performed in a dental office, is the most effective way to brighten your smile quickly. This method uses significantly higher concentrations of whitening agents, such as hydrogen peroxide or carbamide peroxide, compared to those available over the counter. During the procedure, the gums and mouth are protected with special isolation materials, and advanced technologies like heat sources, UV lights, or lasers are often used to activate and accelerate the whitening agents. This allows for dramatic results in just a single session, which typically lasts between 60 to 90 minutes. Depending on the initial level of discolouration and desired whiteness, some patients may require more than one treatment to achieve their optimal results.

At-Home Whitening

At-home teeth whitening offers a more gradual and controlled approach to improving your smile. Available in forms such as gels, strips, and custom-fitted trays, these products contain lower concentrations of whitening agents, making them safe for unsupervised use. Custom-made trays, provided by dentists, ensure a precise fit and effective coverage, allowing the gel to evenly contact all surfaces of the teeth. To see visible changes, these products need to be used consistently as instructed—typically daily for several weeks. This method is particularly appealing for those who prefer to manage the whitening process on their own schedule and is effective in reducing the appearance of surface stains with minimal sensitivity.


Tips to keep your teeth white

After undergoing a teeth whitening treatment, maintaining the results can extend the vibrancy of your smile. Here are some enhanced tips to help keep your teeth looking their best:

  • Avoid stains: Immediately after treatment, steer clear of coffee, tea, red wine, berries, and dark sauces for at least 48 hours as your teeth are more prone to staining.
  • Maintain oral hygiene: Brush at least twice a day using fluoride toothpaste and floss daily. Incorporate an antiseptic mouthwash to kill bacteria and freshen breath.
  • Use whitening products: Employ whitening toothpaste to combat surface stains and occasional touch-up kits, if recommended by your dentist, to prolong effects.
  • Reduce smoking: Tobacco can significantly darken teeth, undermining whitening results.
  • Limit acids and use a straw: Reduce exposure to acidic foods and drinks, and use a straw for beverages that might stain or erode enamel.
  • Regular dental checkups: Visit your dentist for cleanings and check-ups every six months to keep your smile in top condition.

Frequently asked questions - Teeth Whitening

Is teeth whitening safe?

Yes, when performed by a professional or under professional guidance, teeth whitening is a safe and effective way to brighten your smile.

How does teeth whitening work?

Teeth whitening involves applying a bleaching agent, typically hydrogen peroxide or carbamide peroxide, which breaks down stain-causing molecules on the tooth surface, resulting in a lighter tooth colour.

How long does teeth whitening last?

The effects of teeth whitening can last from several months to up to three years, but this varies depending on lifestyle and oral hygiene. Regular touch-ups and good oral care can prolong the results.

Will teeth whitening work on all types of teeth?

Whitening works best on natural teeth and may not affect existing dental restorations such as crowns, veneers, or fillings.

Can I whiten my teeth if I have fillings, crowns, or veneers?

Teeth whitening does not change the colour of dental restorations; it only lightens natural teeth. It’s important to consult with your dentist on how best to match your natural teeth to any existing dental work.

Are there any side effects of teeth whitening?

Some people may experience tooth sensitivity or mild gum irritation during or after the whitening process, but these symptoms are usually temporary.

How do I maintain my whitened teeth?

Avoid stain-causing foods and beverages, reduce smoking, maintain diligent oral hygiene, and consider using whitening toothpaste.

How often can I whiten my teeth?

It’s best to follow your dentist’s recommendations, but typically, professional whitening can be safely done once a year with occasional at-home touch-ups.

Does teeth whitening cause permanent tooth sensitivity?

No, any sensitivity from whitening treatments is usually temporary. Using toothpaste designed for sensitive teeth can help alleviate symptoms.

How soon will I see results from teeth whitening?

Results from in-practice whitening are typically seen immediately after the procedure, while at-home treatments may take several weeks to show noticeable changes.

Can teeth whitening damage enamel?
