Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Calcium formate is a calcium salt commonly used as a dietary calcium supplement. Calcium itself is a well-established mineral necessary for the development and maintenance of healthy teeth and bones. The rationale for using calcium formate to support the teeth is based on its bioavailability—studies indicate that calcium from calcium formate is absorbed efficiently compared to some other calcium salts, such as calcium carbonate or calcium citrate.[1] However, the bulk of scientific evidence focuses on calcium in general, not specifically on calcium formate for oral or dental health.

There is a lack of direct clinical trials evaluating calcium formate supplementation specifically for dental outcomes (e.g., caries prevention, enamel mineralization, or periodontal health) in humans. Most recommendations for calcium supplementation to support teeth are based on the broader body of evidence linking adequate calcium intake to the prevention of dental and skeletal problems, especially during growth and in older adults. The formate component does not appear to have any unique benefit for the teeth beyond its role as a calcium carrier.[2]

In summary, while there is scientific rationale for using bioavailable forms of calcium (including calcium formate) to maintain healthy teeth, direct scientific validation specific to calcium formate and dental health is limited. Thus, the evidence level is moderate (2 out of 5), reflecting established knowledge about calcium’s importance but limited data on this specific form.
