Ideal age of interceptive orthodontics is -
Interceptive orthodontics aims to intercept and correct a developing malocclusion at an early stage, before it becomes fully established. This window corresponds to the mixed dentition period (roughly 6–12 years), when both primary and permanent teeth are present. During this period, problems such as crossbites, crowding, habits (thumb sucking), and arch-length discrepancies can be corrected more easily because the jaws are still growing and teeth are still erupting, making treatment simpler and more effective than after the permanent dentition is fully established.

Trismus refers to a spasm/tonic contraction of the muscles of mastication resulting in restricted mouth opening. It is most commonly caused by inflammation or infection involving the muscles of mastication — for example, pericoronitis, odontogenic space infections (masticator space), or post-injection infection — which trigger a protective muscle spasm. Jaw deviation and muscle weakness are not causes of trismus, and TMJ ankylosis produces a fixed, structural (non-spastic) limitation of opening rather than muscle-spasm-related trismus.
