Everyone wishes for something. For some, it is to be an inch taller. For the rest of us, it might be to have teeth a shade whiter. It didn’t take long for household brands to capitalise on that – the promising whitening toothpaste that allows us to keep our teeth clean and whiter at the same time. Tubes after tubes, nothing changed. How come?

First, we need to know the causes of teeth discolouration. These are as follows:

Extrinsic stains

These are, broadly speaking, anything that we ingest. It can be from our diets such as coffee, or also tobacco smoking. These stains are best removed with polishing and whitening.

Intrinsic stains

Some teeth are born naturally darker in shade. It usually involves the whole dentition. Other situation involves isolated teeth. This turns darker due to internal breakdown of the pulp. This is commonly on a dead tooth where often only an isolated tooth is darker. This tooth will require root canal treatment followed by internal whitening and/or crown/veneer to appear normal again. Internal whitening involves dentist placing whitening gel inside the tooth after root canal treatment before sealing the cavity again. The gel will be replaced as many times as necessary. For generalize teeth whitening, one can either go for laser chair-side whitening or tray system take home kit.


Fluoride is beneficial for teeth, until it passes its optimum level. Too much of it causes brown and white spots on teeth. Spot whitening and/or micro-abrasion will better target the affected areas. Micro-abrasion works by gently removing the discoloured regions, and spot whitening focuses the whitening effect on the brown areas only to make the teeth even coloured.
