13.4.3 Treatment
As with hypodontia, the active cooperation of paediatric dentist, orthodontist, and
restorative dentist should be encouraged to optimize treatment planning for young
people affected by these conditions from an early age.
A megadont maxillary central incisor can be cosmetically unaesthetic and treatment
decisions may need to be considered soon after (or, in some cases, before) eruption of
the tooth. The options include acceptance, remodelling of the tooth, extraction of the
tooth with orthodontic treatment if necessary, and subsequent masking of the space
with a bridge, denture, or implant (803HFig. 13.11).
A microdont tooth, particularly if this affects the maxillary lateral incisors, may be
modified by acid-etch composite material being added to the tooth to reproduce the
typical contours of the crown. (804HFig. 13.12). In adult life, porcelain veneers may also
be used or the tooth can be crowned.
