Types of tooth whitening

Are you looking for a whiter smile and not sure where to start in regards to tooth whitening?

Are you debating whether you should get your teeth whitened at the dentist or from an over the counter tooth whitening kit? No fear we have outlined the two types of tooth whitening available to you and what to do before you whiten your teeth. 

Tooth whitening using bleaching agents

The tooth whitening kits that you can get from your dentist or the over the counter use peroxide-containing bleaching agents. This means the tooth’s actual colour is being altered from the bleach. During the process, you may experience temporary irritation on the gums and other soft tissue. 

The bleaching agent comes in several forms. If you get a tooth whitening kit over the counter, it will most likely be in a strip or paint form. If you get the kit from your dentist, it is in the form of a gel that is placed in a fitted tray. The bonus of buying a kit from your dentist is you will have a consultation to ensure bleaching is the right method for you. 

Tooth whitening using toothpaste (dentifrices)

This is a less abrasive form of whitening in the form of toothpaste. Instead of altering your tooth colour the toothpaste removes the surface stains from the tooth either by polishing or chemical agents. 

Before you whiten

Before using a bleaching programme, it is recommended you consult with your dentist. This is especially important if you have multiple fillings or a crown, bridge, or dental implant. False teeth do not work with bleaching agents, and your dentist can help you avoid various shades of teeth colours in your smile. 

If you have dental decay, receding gum or cavities you may experience increased sensitivity and the product may not work correctly. 

It is best to have a dental cleaning before using a whitening product to remove any plaque or food buildup.
