Blueberries and blackberries are winter favourites and good for oral health.

Hundreds of studies show that berries provide a protective effect against oxidation—a principal cause of cellular damage and a major contributor to illness including oral disease.

Blackberries and blue berries get their intense colour from polyphenol antioxidants that have anti-inflammatory, anti-viral, and anti-microbial properties, and thought to be key to improving the condition of our mouths.

From cold sore, to cavities and gum disease – winter berries are hold great promise:

Cold sores:

Dr. Mumper and Dr. Craig Miller of the University of Kentucky reported in the September 2011 issue of Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology & Endodontics, that an application of blackberry extract on the herpes simplex virus (HSV) was found to have virucidal effects 1.  The study concluded that a topical treatment containing the extract might prove highly effective in treating oral lesions associated with HSV1.

 

Reducing gum disease:

Our two berry champions show great promise for gum disease. Blackberry extract significantly reduces (by 40%) the metabolic activity of key oral bacteria, Porphyromonas gingivalis and Fusobacterium nucleatum (both known to cause periodontal disease)1.  And, blueberry extract has been found to reduce Fusobacterium nucleatum (which plays a role in gum disease) biofilm by 90%2.

Currently, the most effective method of preventing pathogenic oral bacteria from causing gum disease is the use of chlorhexidine mouthwashes. However, long-term use can lead to oral staining and increased tartar build up. Blackberry extract offers a potential alternative that is safe for long-term use.

Reducing tooth decay:

There’s also evidence that blackberry extract reduces bacteria that cause cavities. Studies showed that blackberry extract resulted in a 30% reduction in Streptococcus Mutans (the key bacteria responsible for dental caries) population in vitro2.
