Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Citrus spp., such as oranges, lemons, and limes, are rich sources of vitamin C (ascorbic acid) and various bioflavonoids. There is scientific evidence supporting the role of vitamin C in maintaining oral health and supporting teeth. Vitamin C is essential for collagen synthesis, which is a critical component of gum tissue and the periodontal ligament that anchors teeth. Deficiency in vitamin C can lead to scurvy, characterized by bleeding gums, tooth mobility, and, in severe cases, tooth loss. Several studies have demonstrated that adequate intake of vitamin C can help reduce the risk of gingivitis and other periodontal diseases. Additionally, the bioflavonoids present in citrus fruits exhibit antioxidant and anti-inflammatory properties that may help protect oral tissues from oxidative stress and inflammation. However, it is important to note that while consuming Citrus spp. can contribute to oral health, the high acidity of citrus juices can erode dental enamel if consumed excessively or without proper dental hygiene. In summary, the use of Citrus spp. to support the teeth body system is scientifically validated, primarily due to its vitamin C content and its role in maintaining gum and periodontal health, but the evidence is moderate rather than strong, warranting a rating of 3 out of 5.
