There is often a genetic link with this trait.
Common missing teeth include the upper lateral incisors and the second premolars. Missing teeth affect aesthetics and can affect chewing.

Every case is different – the treatment decision for each individual is complex and requires careful analysis of all associated growth, facial and dental factors.
