The most soothing thing you can do is often to rub sore gums gently with a clean finger or with the back of a cold plastic spoon or cold wet cloth. Teething rings often work well. It is best to avoid teething biscuits, they may contain sugar that is not good for baby teeth. Infant tylenol can also be used, especially prior to bedtime if your child is fussy. Just be sure to BRUSH or WIPE the teeth afterwards.
