Are teeth that contain fillings matched with other teeth so they are unnoticed?

Tooth-coloured front fillings may have matched beautifully when they were put in, but they usually only look good for three to five years. Certain foods stain but especially coffee, tea and smoking, cause the fillings to discolour and may require more professional cleaning or more frequent replacement. Later, crowning may be necessary to not only restore, but change the shapes of your teeth for a more attractive smile.
