Since young, we’ve been told by parents and teachers to brush our teeth and avoid sweets. Good advice. Brushing away the plaque on our teeth will prevent tooth decay. Avoiding sweets is also a good preventive measure.

The good and bad thing about tooth decay is that it starts off without any symptoms. If it’s a front tooth, you may notice some greyish or brownish discoloration. For back teeth, you may not notice it at all. But as the decay gets deeper and deeper, the tooth may feel sensitive to cold stuff. That’s when the decay is getting into the second layer or the dentine layer of the tooth and the nerve begins to feel it.

This is your last chance to fill the do. The dentist drills to clean out all the decay and then fills up the cleaned cavity with cement or composite material which is plastic when inserted and solidifies when treated with a light.

Whether a filling can hold depends on many factors. The size of the cavity is one. The longer you delay treatment, the the larger, deeper and harder it is to fill the cavity. The location of the cavity is also an issue. Some surfaces are harder to fill than others.

Of course, if the cavity has reached the pulp, then fillings won’t work anymore.
