• Inadequate cleaning/filling of narrow or curved canals
• Perforations
• Presence of an additional canal which may have been missed
• Salivary/bacterial contamination of a root canal filling due to recurrent caries or poor fitting filling or a crown.
• Delayed placement of a permanent restoration following an endodontic procedure

Many patients tend to opt for extraction following the failure of their root canal treatment, but it is important to remember that it is better to save the natural tooth if possible. Dr. Salmeron can help to determine if your tooth can be saved with root canal retreatment.
