Cavities are expensive!  Help spread the word that daily sunshine and vitamin D might be just as important to dental health in our children as regular brushing and flossing

Tooth enamel, which is the hard, outer surface of a tooth that protects against decay, primarily consists of calcium and phosphate. Vitamin D plays a key role in the absorption of calcium and phosphate, therefore, inadequate vitamin D can cause a lack of enamel, which can lead to cavities. Studies have linked vitamin D deficiency, in both the mother during pregnancy and the child after birth, to an increased risk of cavities. Today, we highlight two studies showing an association between vitamin D and childhood cavities.

Study #1: Cord Blood Vitamin D Levels and Childhood Cavities

A study published in March, 2019, in the Journal of Dental Research, assessed the association between maternal vitamin D levels during pregnancy and the rate of severe early childhood cavities in Alaska Native children. Cavity status was determined by a score based on the amount of decayed, missing, or filled primary teeth. In 43 children between one and three years of age, the research team found that children with cord blood vitamin D levels at or above 12 ng/ml (30 nmol/L) had half as much tooth decay as children with cord blood vitamin D levels below 12 ng/ml (P = 0.002).

Study #2: Child Vitamin D Levels and Childhood Cavities

In September 2018, a study assessing the relationship between vitamin D levels in children and early childhood cavities was published in the Journal of Dentistry for Children. This study examined 276 children aged one to six years old who received care at Seattle Children’s Hospital between 1999 and 2014. The research team found that children with vitamin D levels at or above 30 ng/ml (75 nmol/L) were half as likely to have cavities as children with vitamin D levels less than 30 ng/ml (P<0.001).

Too Many Children Are Vitamin D Deficient

Unfortunately, many children are not getting enough vitamin D, and the problem seems to worsen as they age.

According to 2009-2014 data from the National Health and Nutrition Examination Survey (NHANES) on children under the age of 18 in the United States, 93% had vitamin D levels below 40 ng/ml (100 nmol/L), with 16% of them below 20 ng/ml (50 nmol/L). That data is charted below next to data on children in the GrassrootsHealth cohort, among whom over 50% are still below the recommended 40 ng/ml, regardless of the fact that the parents testing their children through the project are educated enough about vitamin D to be measuring levels on their own.

How Can You Use this Information for YOUR Health?

Having and maintaining healthy vitamin D and other nutrient levels can help improve your health now and for your future. Measuring is the only way to make sure you are getting enough!

STEP 1 Order your at-home blood spot test kit to measure vitamin D and other nutrients of concern to you, such as omega-3s, magnesium, essential and toxic elements (zinc, copper, selenium, lead, cadmium, mercury); include hsCRP as a marker of inflammation or HbA1c for blood sugar health

STEP 2 Answer the online questionnaire as part of the GrassrootsHealth study

STEP 3 Using our educational materials and tools (such as our dose calculators), assess your results to determine if you are in your desired target range or if actions should be taken to get there

STEP 4 After 3-6 months of implementing your changes, re-test to see if you have achieved your target level(s)
