Lingual therapy has what trade-off compared to labial therapy?

Increased ease of use Shorter treatment Lower cost Increased difficulty, duration, and cost

Correct Answer:

Increased difficulty, duration, and cost

Explanation:

Lingual therapy hides braces on the tongue-facing surfaces, which makes placement, adjustments, and overall tooth movement more technically demanding. This interior placement requires precise customization, more specialized equipment, and often extra laboratory work, plus clinicians need greater experience to manage the unique mechanics and potential tongue irritation. All of that tends to increase the time spent in the chair, can extend the overall treatment duration, and raises the cost due to materials, lab work, and specialized expertise. So the trade-off is increased difficulty, duration, and cost. It isn’t easier, shorter, or cheaper.
