Third most frequently impacted tooth according to the provided order is which?

• A. Mandibular third molars
• B. Maxillary third molars
• C. Maxillary canines
• D. Mandibular canines

Answer: (C)

The pattern of tooth impaction follows how difficult eruption is and how much space is available in the dental arch. The mandibular third molars are the most commonly impacted because they erupt late at a crowded end of the arch. The next in frequency are the maxillary third molars, which also face limited space and a awkward eruption path. The third most frequent impaction is the maxillary canines. They have one of the longest and most complex eruption trajectories and rely heavily on guidance from the lateral incisors. If the lateral incisors are missing or peg-shaped, or if there isn’t enough space in the canine region, the maxillary canines often fail to erupt and become impacted, usually palatally. So, the maxillary canines ranking third fits with how eruption paths and space issues influence impaction rates.
