Stage 4 of tooth decay

In addition to compromising the vitality of the tooth, the infection that has invaded all of the dental pulp can extend and form an abscess at the bottom of the root. The accumulation of pus in the abscess is actually a protective measure from the body to prevent the spread of infection.

Without the removal of the pus, symptoms like swelling, fever and acute pain will appear.  If the tooth is too affected by decay, tooth extraction will likely be the only way to eliminate the infection.

It is also important to know:

  • Misaligned teeth can be more difficult to brush which promotes plaque and tartar build-up.
  • The presence of cracks (e.g.: broken tooth) reduces the protective power of enamel.
  • Defective fillings can allow infiltration of decay.
  • Sensitivity to cold, warm and sweet drinks or food may indicate the presence of cavities.
