Is there a chance of tooth decay if my tooth filling was placed before my tooth was dry?

It is definitely possible to have pulp (the nerve of the tooth) damage in the absence of decay. Other causes of pulp damage/inflammation include:1) Cracks in the tooth or rootHairline cracks may be present in the crown or the root of a tooth due to trauma (from an accident, teeth grinding or clenching, or biting into something hard) or weakening of an undermined cusp usually associated with a large cavity or a large filling. Most cracks may be painless when confined to the superficial part of the tooth.

There are 4 methods to detect decay, and the best method depends on the exact location of the cavity and also the stage of decay. Essentially, large cavities are easier to detect but are more complicated to treat. 1) Visual This is done by scanning your teeth surfaces that have been dried and observing colour or textural changes. This is routinely done during all dental examinations. Detection of cavities is improved with good light and magnification (using loupes or even a microscope).
