If you are unable to clean your mouth directly after eating, consider chewing sugar free gum. This will stimulate saliva in your mouth that will naturally help flush out any lingering remnants of food. Also sugar free lollies will promote a similar mechanism.
High fluoride toothpastes should be used only in consultation with dental advice. They usually have five times the fluoride content of normal toothpaste and are advised in patients who are high-risk to dental decay. Other agents such as CPP-ACP (casein phosphopeptide – amorphous calcium phosphate), which are effective in helping remineralise the tooth, are being promoted in patients prone to erosion, dental decay, and dry mouth.
