Decongestants and antihistamines both cause dry mouth as a side effect— and dry mouth is one of the more underappreciated dental risks during illness.
Saliva isn ' t just moisture. It ' s the mouth ' s natural defence system: it neutralises acid, washes away food particles, and delivers the minerals that remineralise tooth enamel after every acid attack.
When saliva flow drops, all of those protective mechanisms slow down simultaneously.
During illness, keep fluids up. Water is best, and it ' s also exactly what a sick child needs anyway. Sugar-free gum or lozenges( for children old enough) stimulate saliva flow.
A humidifier in the bedroom at night helps counteract the drying effect of breathing through a blocked nose, which brings us to another issue: a blocked nose means mouth breathing, and mouth breathing means dry mouth. Even a few days of illness-related mouth breathing has a measurable effect on oral moisture levels.

Brushing twice a day matters even more during illness. The combination of medication sugar, dry mouth, and reduced immune function creates elevated decay risk. The challenge is that sick children( and their exhausted parents) often let the routine slip. Keep it simple: even a brief, gentle brush is better than nothing.
Toothbrush After Illness Replace your child ' s toothbrush after a fever-based illness, Bacterial and viral contamination can linger in the bristles. Between family members, ensure toothbrushes are stored separately so bristles don ' t touch.
