Dental caries is considered an infectious transmissible disease within our saliva. Mutans Streptococci (MS) is considered to be the principal group of bacteria responsible for the invitation of dental decay. MS adhere to teeth, metabolize sugars and produces acids that demineralize tooth structure. Babies are not born with MS, but colonization may occur at the time of birth and over 70% of the time it is transmitted by their mother or primary caregiver (1,3).
The higher the levels of maternal/primary caregiver salivary MS, the greater the risk of the infant being colonized at a younger age. In order to suppress the reservoirs of MS, it is important for the mother or primary caregiver to maintain a healthy well rounded diet, reduce the frequency of simple carbohydrate intake, applying topical fluoride at routine dental visits, restoring active caries, and chewing xylitol gum.
Xyltiol Gum Reduces Plaque Production
Xyltiol is a 5 carbon sugar alcohol that looks, tastes and has similar sweetness to sucrose, but with 40% fewer calories. It is plant derived and is found in small quantities in fruits and vegetables. It has been shown to reduce the production of plaque and number of MS in the mouth. Evidence has shown that parents that chewed xylitol gum (4 pieces a day for 20 minutes) as early as 3 months after birth can significantly decrease the child’s caries rate(2).
Preventing Tooth Decay in Children
Transmission of caries can also occur between siblings of similar age or children in daycare(1).
A healthy smile for your child starts before they are born. By the age of 1 or 6 months after their first teeth erupt, it important that they see a pediatric dentist for an initial exam, cleaning, and fluoride treatment. Follow these helpful hints to prevent the spread of Mutans Streptococci (MS).
- Don’t cut your child’s food into smaller pieces by biting it in half.
- Don’t clean off a dropped pacifier or bottle by putting it your mouth first.
- Don’t blow on your child’s hot food to cool it off.
- Don’t share eating utensils.
