Saliva plays a large part in the formation of plaque, and within a few minutes of cleaning, the tooth is covered in a sticky film made from salivary proteins, called the salivary pellicle. This provides receptors for early bacterial colonisers to attach to. Initially, these connections are weak and easily broken. These early aerobic bacteria are gram‐positive (stain violet when exposed to Gram’s stain in the laboratory), and feed on sugars from the diet.
