Omega-3 Fatty Acids
A 2014 study showed that taking about 300 kilograms of omega-3 fatty acids daily for 12 weeks can reduce gingival index and improve gum-to-tooth attachment. Gingival index evaluates the severity of gum inflammation. Studies also show that omega-3 fatty acids can help prevent chronic periodontitis.
Turmeric Gel
Turmeric contains curcumin, a substance that is known for its anti-inflammatory and antioxidant properties. A 2015 study showed that turmeric gel may help prevent gingivitis and plaque, which may be responsible for receding gums.
