How Does Teeth Whitening Work?

After teeth whitening treatment

One of the most common questions asked about teeth whitening is “how does teeth whitening work?” We’ll break it down for you so you understand the process and what’s involved when you get your teeth whitened.

Teeth whitening is a process used to lighten the colour of discoloured and stained teeth. Although whitening can be done at home, consider having your teeth whitened at a dental practice for the best results. Keep reading below to find out everything you need to know about the active teeth whitening process.

How Are Teeth Whitened?

So, how does teeth whitening work? Teeth whitening involves bleaching agents, such as hydrogen peroxide and carbamide peroxide. They are used to remove surface stains caused by food, drinks, smoking, and other activities.

These bleaching agents penetrate the enamel of teeth and break down discolouration so that white teeth can emerge.

Professional treatments at your local dentist may also include heat or laser technology to help accelerate the whitening process. After the high-concentration bleaching gel has been applied to the teeth, the bleach is activated with a UV light. This is a highly effective teeth whitening method and is completely safe when supervised by a professional.

With proper care and maintenance, white teeth achieved through teeth whitening can last for many years.

Can Fillings Be Whitened?

Our teeth are made of enamel. Fillings, crowns and veneers are not. This means that they cannot be whitened along with your natural teeth because the bleaching agent will not react the same way as it does on enamel.

If you know you need dental work and are interested in having whiter teeth, we recommend having teeth whitened first.

How Immediate are In-Chair Teeth Whitening Treatments?

Results differ for every patient but some dental patients will see an immediate result with whiter teeth after treatment by a dental provider.

Many dentists use a 35% solution of hydrogen peroxide along with a UV light for optimal results. Take-home teeth whitening kits only use 7-10% so results won’t be as obvious. Because in-chair tooth whitening is supervised by qualified professional dental clinicians, you run less risk of causing damage to your teeth, gums, and mouth.

Maintain white teeth

For those interested in achieving white teeth, it’s important to speak with a dentist about the best whitening option for your particular situation. A dentist can help assess the condition of your teeth and determine which method will give you the most effective and long-lasting results.

Regardless of the approach that is chosen, white teeth can be achieved with a safe and professionally directed procedure. With white teeth, patients feel more confident in their smiles and become more likely to show off their pearly whites with pride. After all, white teeth are one of the most attractive features we have!
