What are all the dental charting symbols?

Dental charting symbols vary by practice, but common symbols include: a circle for decay, an "X" for a tooth that is extracted, a filled-in circle for a root canal, a line through a tooth for a missing tooth, and a triangle for a crown. Additional symbols may indicate fillings, periodontal issues, or orthodontic treatments. Each dental office may have its own specific key for interpreting these symbols, so it's essential to refer to the provided legend.
