The Pros and Cons of Teeth Whitening

It's one of the fastest growing areas of cosmetic enhancement so it's important to get the right advice. Here's the down-low for people considering getting their teeth whitened.

Everybody wants a brighter, whiter smile; and professional teeth whitening is the best way to get your teeth to their brilliant best.

Teeth whitening is an accessible cosmetic dentistry option for almost every patient, and is universally safe and effective because rather than mask discolouration, it brings out the natural whiteness in teeth by neutralising pigments and stains - teeth just look better when they are white- not yellow, not grey, not brown. Here are some of the pros and cons associated with teeth whitening:


  • Whiter brighter prettier teeth
  • Makes you look younger
  • Relatively inexpensive
  • Immediate results
  • Non-invasive


  • Can cause some sensitivity for 24 hours post whitening treatment
  • For 24 hours after your in chair whitening treatment (or for as long as you’re whitening for at home) you need to abstain from having tea, coffee, red wine or eating things like red sauces, soy sauces, butter, curries  -  basically anything that will stain your white t-shit, will stain you teeth!
  • Teeth become super porous and dehydrated from the hydrogen peroxide gel so it’s necessary to allow for the teeth to re-mineralise otherwise, your teeth will just soak up all the staining and kill your whitening.

What you should look for when choosing a treatment/ dentist to ensure you get the best results.

Find out what whitening system and products the dentist uses. There are so many out there (britesmile, Zoom!, Polawhite are probably the most popular ones) some don’t achieve results as well as others, some cause more sensitivity than others, so it’s important to know what product  you’re getting pre-treatment.
