Teeth whitening treatments explained.
Teeth whitening can be achieved through a number of different methods, but the best results are often gained through seeing a dental professional, it has been stated. 
Big News reported anyone considering teeth whitening could get an over-the-counter product. However, take-home kits will often contain harmful chemicals and therefore it may be more prudent to have this treatment carried out by a trained professional.
The online resource noted: “The change in the colour of the teeth [is a] combined effect of a number of factors and depends on the age of the person, bacterial presence, food stuff sticking and other external toxins like nicotine in smoke.”
Anyone who has stains or bad discolouration may also find that take-home kits are not suitable for them, the article concluded.
Elsewhere, the American Academy of Pediatric Dentistry recently noted anyone thinking of having a teeth whitening treatment carried out should remember the risks involved, including the possibility of increased tooth sensitivity, tissue irritation or possible root damage.
