Best Whitening Toothpastes: 5 Things To Consider

Published date field

Supermarket shelves are stacked high with whitening toothpastes promising to give you a bright, sparkling smile. With so many to choose from, how do you know which whitening toothpaste is best for you?

The right whitening toothpaste depends on a number of factors, including the cause of your tooth discolouration, your smile goals, and your individual oral health needs.

Here, we discuss the main differences between the various types and highlight the five key things to consider when choosing your toothpaste.

1. Cosmetically Active Ingredients

Whitening toothpastes work in one of two ways: stain removal or bleaching. They each achieve results using different active ingredients.

Surface Stain Removers

Whitening toothpastes that remove surface stains essentially work by polishing the teeth with abrasive active ingredients.

If your teeth are stained from tea, coffee or red wine, for example, such a toothpaste can help to gently buff away the surface discolouration and improve the colour of your smile.

Bleaching Agents

Some whitening toothpastes and gels lighten the teeth with bleaching agents, such as hydrogen peroxide.

These ingredients penetrate deep into the teeth to remove the molecules that cause discolouration and lighten the dentine inside the tooth. They can also give a brighter appearance by making the enamel surface more reflective.

While toothpastes with bleaching agents typically give quicker and better results than other whitening toothpastes, they can also lead to tooth sensitivity and gum irritation.

2. Sensitivity

Some people experience sensitivity when using whitening toothpastes. If your teeth and/or gums feel sore after you use a whitening toothpaste, consult your dental professional for advice.

3. Enamel Protection

Strong enamel makes it more difficult for stains to penetrate and discolour your teeth, so protecting your enamel can help to keep your smile bright and white.

Toothpastes and mouth rinses containing fluoride can protect your smile by helping to re-mineralise and fortify the tooth enamel. Colgate Australia sells Colgate Optic White Enamel White, with high fluoride content to support your enamel.

4. Added Benefits

Choose a whitening toothpaste that also offers cavity protection, plaque control, or other oral health benefits. After all, you want your teeth to be white and healthy! Your dentist can advise you on options that meet your individual requirements.

5. Safety and Effectiveness 

While whitening toothpastes and home whitening products are generally safe, some ingredients may not be suitable for everyone. You should also consider that certain types of discolouration respond differently to whitening treatments.

Health Direct points out that whitening toothpastes and other products will not work on existing crowns, veneers or fillings. This may lead to uneven colouration on visible teeth, so your dentist may recommend a different treatment to achieve the desired results.

The ADA agrees that your dentist is best-qualified to advise on teeth whitening. With this in mind, it’s always wise to consult your dentist first to determine if your chosen teeth whitening option is safe and suitable for you.
