How is that going to affect him or her?
Children require extraction of one or more primary teeth in certain situations. These situations may include extensive decay on their front teeth, and/or localized infection (for example an abscess or a gum boil).
Extractions are also necessary in cases of trauma, where the baby teeth have been pushed back, pushed forward, broken or simply knocked out.
Parents are obviously concerned of the aesthetic and functional effects (on speech, feeding, and breathing) of removing one or more front baby teeth.
There is good evidence that has shown NO long-term speech impediments on these cases. We also know from our professional experience that once the gums heal, children will be able to eat almost anything, since they can still bite-and-cut with the remaining teeth.
As far as aesthetics is concerned, your pediatric dentist can offer you information on fixed appliances that can replace the missing tooth/teeth, assuming your child meets the right criteria.
