Hi there and thank you for your question.
As the link you have provided suggests, microabrasion definitely does have a place in the management of tooth discolouration. We sometimes use it in isolation and at other times in conjunction with other means of correcting tooth colour.
Do bear in mind though that not every case will respond well to microabrasion and some discolouration may be too deep seated to be corrected by microabrasion alone. A prior clinical assessment to determine suitability is of course necessary.
There is however no downside to trying as microabrasion is a very conservative approach to correcting discolouration!
Hope this helps!
