How does teeth whitening work?

Teeth whitening can be an excellent option for restoring your bright smile if you've noticed that your teeth have become yellowed or dull-looking.

The essential ingredients in teeth whitening products are peroxides, typically hydrogen peroxide or carbamide peroxide. The peroxides contain oxygen molecules that break apart the chemicals bonding stains to your teeth, restoring the bright, white appearance of your smile.

Why Professional Products Are More Effective Than Over-the-Counter

Professional teeth bleaching products that your dentist has access to typically contain a higher concentration of the peroxides that brighten your smile. Your Perth dentist can customise your bleaching gel to the ideal strength that you need to reach your smile goals.

Over-the-counter products you buy at the store may brighten your teeth, but since they're a lower strength to protect your teeth from damage, it could take longer or even be impossible to achieve the results you're looking for.

In addition to containing hydrogen peroxide or carbamide peroxide, professional strength whitening gel from your dentist also contains fluoride, which protects your tooth enamel and reduces the sensitivity that some people experience with teeth whitening.
