The basic difference
A complete denture replaces every tooth in an arch. A partial denture replaces selected missing teeth and works alongside the natural teeth that remain.
Why remaining teeth matter
Natural teeth can help support and retain a partial denture, which changes how it is designed. The health of those teeth and their supporting gum and bone is therefore assessed carefully before planning.
Choosing between them
This is a clinical decision rather than a preference. Your dentist will consider the number and position of missing teeth, the condition of remaining teeth, bite, gum health and your own priorities before recommending an option.
