As we age, it is inevitable that our teeth become more yellow. This is due to the ‘second layer’ of our tooth, the dentine, becoming more dense, therefore darkening in colour in combination with our enamel (the white outer-layer) becoming worn.
The natural effect of aging in combination with staining from environmental factors caused by different foods, drinks and smoking discolour our teeth.
Teeth whitening is therefore the option which many people consider once their teeth start to yellow.
There are two types of teeth whitening
This involves the removal of external staining caused by food and drinks including red wine and coffee as well as smoking tobacco.
Whitens the dentine layer of the tooth. This is done by using whitening gels containing hydrogen peroxide or carbamide peroxide. As the now lighter dentine shines through the enamel making the teeth appear whiter.
Therefore, following a scale and clean where the extrinsic stains are removed, if the teeth still appear yellow, you may consider using a whitening gel to make your teeth appear more white.
One of the most commonly asked questions we get asked at our clinic is “do you do teeth whitening? (aka bleaching)”. The answer to this question is yes, we do. We offer in-chair whitening and take-home whitening kits.
What is HiSmile teeth whitening?
HiSmile is currently being advertised everywhere – Facebook, Snapchat and Instagram with many celebrities promoting the product.
"When I stumbled across this study performed by Method Dental, I was not surprised that Dr Mc Grath came to the conclusion that Hi Smile did not cause any significant change in the shade of the teeth" states our Clinic Director.
Dr Mc Grath states that in comparison to professional systems which have a track record of production of safe materials, stating the country of manufacture and also the concentration of the active ingredient, HiSmile doesn’t. HiSmile do not state where the products are sourced from, the concentration of the key ingredients or where it is manufactured. Also,the ingredients used at a pH that is suitable for the human body have been shown to have no whitening effect.
Dr Mc Grath concluded that the difference in tooth colour in the images seen online are due to lighting conditions when the photo is taken and editing the photo's ‘white balance’. Furthermore, there are no before and after images of celebrities using the product. Watch the video here to view the full investigation by Dr McGrath.
If you would like whiter teeth, the best option is always going to be a recommendation by your dentist who knows your teeth.
