Swollen Tonsils

Grab a flashlight to take a look at your children tonsils. Healthy tonsils should be pink and spot free, but infected ones are red, inflamed, possible white spots, and terrible odor. Bacteria can collect in the pits of swollen tonsils causing bad breath. and, paired with the sour smell of infection, can cause bad breath. If your child’s tonsils look swollen or red, your pediatrician should examine them and can prescribe an antibiotic.

Dry Mouth
