Summary:
A complete protein is a protein source that "contains adequate proportions of the nine essential amino acids" that our body can not produce on its own.
A decent source of supplementary protein, a single slice of whole wheat bread contains 3.5 grams of protein, or about 7% of recommended daily values. [1]
To get the adequate amount of protein with whole wheat bread alone, you will need 14 slices of whole wheat bread (374 grams) for an average female, or 17 slices of whole wheat bread for males. [4] That's about 992 calories.

Proportionally, whole wheat bread does contain abundant amounts of 1 out of the nine essential amino acids. However, whole wheat bread is a little short on histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine and valine.[1]
To have adequate amounts of all nine essential amino acids with whole wheat bread alone, you will have to eat 24 slices of whole wheat bread (623 grams) for an average person. [2]
That's about 67% more whole wheat bread to compensate for the lack of histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine and valine, compared to the protein requirement alone.
