Whitening toothpastes are one among many products available that can whiten teeth.

Teeth whitening help to remove stains caused by food, age-related discoloration, trauma etc.

Teeth whitening can be done by those who have healthy teeth and gums and without any restorations like fillings or crowns in their teeth.

Whitening gels, strips, toothpastes, mouth trays, rinses are the common over-the-counter whitening products available.

Whitening toothpastes are ideal for removing extrinsic or surface stains for they contain mild abrasives like calcium carbonate or silica.

They may sometimes contain chemicals like hydrogen peroxide or polishing agents to make them more effective whitening agents.

Most whitening toothpastes can lighten teeth by one shade since they may not contain bleaching gel or have them in very small quantities.

Side Effects of Whitening Toothpastes

Whitening toothpastes are generally safe to use and may not cause any side effects.

Since whitening toothpastes contain mild abrasives, they must be used with caution.

Excess brushing with this can scratch the surface of the enamel and the natural shine of your teeth will be lost.

In fact, when enamel gets worn out like this, teeth can appear discolored and it can even lead to tooth decay.

If the whitening toothpaste contains peroxide, it must be used with caution especially by those who have an allergy to this agent or have sensitive teeth.

Peroxide can increase the sensitivity of teeth and gums.

Dentin which is the underlying layer can get exposed and increase our sensitivity to cold and hot beverages.

Consult your dentist on the right whitening toothpaste to use. A gentle whitening product used with a soft toothbrush can help whiten teeth without causing side effects.  

You can begin by first brushing teeth gently with and then floss and use the whitening toothpaste. Make sure the whitening toothpaste remains on teeth for not more than 2 minutes and then rinse thoroughly with water.  


You must always observe certain precautions when using home whitening kits for your teeth like whitening toothpastes.

First, before buying a product, make sure you are not allergic to the ingredients found in the toothpaste.

Some people could be allergic to peroxide and this can increase the sensitivity of teeth.

Anyone with dental problems like cavities, gingivitis, worn enamel or exposed roots must first get these treated by a dentist before using whitening toothpaste.

Fillings, bonding, bridges and other dental work will not get whitened. This can cause uneven whitening. Do not use peroxide-based whitening toothpaste if you are wearing braces.

Teeth will not only get unevenly whitened but the metal on the brace can change color due to oxidation when they come in contact with peroxide.

If you are on any prescription medications, ensure that the ingredients found in the whitening toothpaste will not react with the medication.  

Whitening toothpastes are a great way to maintain teeth which have been whitened by in-office or at-home whitening systems. They maintain healthy teeth and gums and also prevent stains from forming.
