When used as directed, ProBiora Kids will help support oral health and is safe, and effective for all ages. For those at risk of choking, grind up the tablet before dissolving in the mouth.
However, if your question is for newborns or infants our general recommendation is you want them to be old enough to chew or suck on the mint. A very young child could potentially swallow the mint and have it stuck in the throat. For example, if you want to use ProBiora Kids with an 18-month old child, you may need to crush the tablet in some water, or dissolve it in the water and then apply the solution to the child’s erupted teeth with something such as a cotton swab, until the child can safely take the product by his/herself, with parental supervision.
