Teeth whitening in New Westminster is a procedure used to lighten the color of discoloured teeth and eliminate stains that leave behind much whiter teeth than toothpaste alone could achieve.  A peroxide-based bleaching product is commonly used by teeth whitening experts as it helps to achieve the whiter teeth that all of us desire. The at home system contains between 3 and 20% peroxide, which are carbamide or hydrogen peroxides, while the in office system contains between 15 and 43% peroxide. 

Typically, the stronger the whitening solution and the length of time it is kept on the teeth the whiter the teeth become. Keeping the solution on for too long will boost tooth sensitivity while also dehydrating the teeth. Bleaching does not have the capacity to whiten porcelain crowns or tooth-coloured composite bondings.

What is tooth discolouration?

Your teeth are discoloured when they are stained or darkened. It could affect a complete tooth or appear as lines or spots on a tooth’s surface. Tooth discolouration comes in two types, which are: 

  • intrinsic or internal, which is discoloration that occurs inside a tooth and is caused by aging, tooth injury, a few health conditions, and some types of medications;
  • extrinsic or external, which is discoloration that occurs when products such as poor dental hygiene, food, drinks, or tobacco causes staining on the tooth’s surface.
