Smile is important. It’s one of the first things someone notices when they meet you. A whiter, ever brighter smile can instantly make you feel better and help making a memorable impression. However, sometimes lifestyle choices such as smoking, drinking tea, coffee, cola or red wine etc. and inevitable ageing process can result in stained and darkened teeth. Over the years medication and inadequate oral hygiene can also contribute to this problem. The change in this process is so gradual that you wouldn’t even notice.
