When decay has started in the tooth it needs immediate attention because the sooner we treat it the better and lesser expensive is the treatment.

 

If the decay reaches the pulp(blood vessels and nerves) then we need to clean the tooth upto roots (Root canal treatment) to make tooth non vital (dead).

 

After Root canal treatment (RCT) tooth becomes brittle. It needs a cap(crown) to save it from fracturing and function well.

 

Brushing, flossing and regular monitoring is highly recommended.
