The Study
Do Adjunctive Therapies with Natural Products Improve Periodontal Clinical Parameters After Non-Surgical Treatment? A Systematic Review and Meta-Analysis
This study looked at lots of different experiments where people used natural things like curcumin or green tea along with regular dental cleaning. It found that, on average, these natural things helped a little bit more than cleaning alone—but only for a few months. It doesn't prove they fix everything, just that they might help a little in the short term.
Analysis score
Maximum 100 for a systematic review with meta-analysis.
Where the score came from
After a dentist cleans deep under your gums (scaling and root planing), adding natural things like turmeric, fish oil, or aloe vera might help your gums heal a little better — but only for a few months.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Even small improvements like 0.8 mm less pocket depth can mean less risk of tooth loss over time — especially for people whose gums don’t heal well after cleaning alone.
- 2Turmeric and fish oil reduced gum pocket depth by about 0.8–0.9 mm; aloe vera cut bleeding by 35–45% at 3–6 months; resveratrol cut pocket depth by over 1 mm at 1 month.
- 3But after 6 months, most benefits faded.

In adults with periodontitis, adding curcumin to dental cleaning reduces gum pocket depth by 0.85 mm after one month and 0.93 mm after three months, but the reduction returns to baseline by six months.
In adults with periodontitis, adding omega-3 fatty acids to scaling and root planing reduces gum pocket depth by 0.9 mm and increases gum attachment by 0.7 mm after three months.
When used with standard gum treatment, aloe vera reduces bleeding from the gums by 35–45% after three and six months in adults with periodontitis, and this effect is supported by moderate-certainty evidence.
When resveratrol is applied along with standard gum treatment in adults with periodontitis, it reduces pocket depth by more than 1 millimeter and lowers bleeding around the gums after one month.
When natural products are used along with deep cleaning of teeth, they lead to small, temporary improvements in gum health measurements, but these benefits typically fade after six months and vary widely depending on the product and study design.
