Garlic Mouthwash Works as Well as Top Antiseptics, Study Finds
A new scientific review suggests that garlic extract may work as well as popular antiseptic mouthwashes. The findings come from researchers at the University of Sharjah, who compared garlic-based rinses with chlorhexidine. Their results point to a possible natural option for everyday oral care.Chlorhexidine is widely used in dental clinics. However, many people avoid it because of side effects and concerns about resistance. Garlic, on the other hand, has long been known for its natural antimicrobial power. Therefore, the team wanted to see whether garlic extract could deliver similar benefits.
How the Review Was Conducted
The researchers followed strict guidelines to ensure reliable results. They used PRISMA 2020 standards and the PICO framework, which help improve transparency and quality in clinical reviews. Their search began with 389 studies across six databases. After screening and removing duplicates, only five studies met all requirements.These studies included both randomized trials and clinical evaluations. Each tested different concentrations of garlic extract. As a result, the outcomes varied slightly from one study to another.
Garlic Shows Comparable Antimicrobial Power
Overall, the review found that high-concentration garlic mouthwash performed similarly to chlorhexidine in reducing harmful microbes. Some studies even reported better results with garlic at specific concentrations. However, garlic rinses caused more discomfort, including a burning sensation or strong odor.In addition, the review noted that garlic’s side effects were still mild compared with some chemical alternatives. The authors also highlighted garlic’s long history as a natural antibacterial ingredient. Its key compound, allicin, is responsible for most of its antimicrobial strength.
Why More Research Is Needed
The findings are encouraging, but the authors call for larger and longer clinical studies. This would help confirm garlic’s effectiveness and make it easier to use as a practical option in dental care. With global garlic consumption rising each year, interest in natural products continues to grow. Therefore, garlic extract may soon gain more attention as a gentle, plant-based alternative.
