Tooth coloured fillings, or composite resins, have become very popular option to restore the back teeth. They look virtually identical to natural teeth.

Composite resins require specific techniques and a dry environment when they are placed. It is not uncommon to find that the teeth are sensitive afterwards. A bigger problem is the development of decay under these fillings over time. Fortunately, both problems can be avoided with good technique.
