Tongue scraping for bad breath with gum disease treatment
This trial checks if adding tongue scraping to regular gum disease treatment can help reduce bad breath more than gum treatment alone.

Resveratrol mouthwash for bad breath study
This trial tests whether a special mouthwash with resveratrol (a natural plant compound) can help reduce bad breath caused by gum-related bacteria. It might be a good option if you have bad breath from gingivitis (mild gum inflammation) and are a non-smoking dental student.
Baghdad, Bab Al-MoadhamAges 20–24 - NCT07463859Recruiting
Treating gum disease and bad breath in diabetes patients
This trial tests whether combining standard gum treatment with a light-activated therapy can reduce bad breath in people with type 2 diabetes and advanced gum disease.
Bauru, São PauloAges 18–70 - NCT07508839Recruiting
Probiotic lozenge study for healthy adults
This trial tests a probiotic lozenge (a dissolvable tablet) to see if it's safe and works well. It's for healthy adults who don't smoke and are between 18 and 70 years old.
Hamilton, OntarioAges 18–70 - NCT06219226Enrolling by invitation
Mouthwash for bad breath study

Budapest, BudapestAges 18 years+ - NCT07693972Recruiting
Probiotic vs zinc mouthwash for bad breath and plaque in braces
This trial compares a probiotic mouthwash to a zinc and chlorhexidine mouthwash to see which is better at controlling bad breath and plaque for people with braces. It aims to find a gentler option that still works well.
Baghdad, AlkarghAges 18–30 - NCT06900881RecruitingPhase 2/Phase 3
Kefir Mouthwash for Healthy Gums
This clinical trial tests if a mouthwash made from kefir, a fermented milk drink, can reduce gum swelling and bleeding (gingivitis) in young adults. You might benefit if you have mild gum disease but are otherwise healthy.
BaghdadAges 18–28 - NCT01793168Recruiting
Rare disease registry and history study
This study keeps a registry (a structured list) of people with rare diseases and may also track how the condition changes over time. It can help researchers better understand rare illnesses and find gaps in care, which may improve future treatments.

Common questions
- Are there clinical trials for halitosis?
- Yes. Clin2 currently lists 10 recruiting halitosis studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a halitosis trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a halitosis trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
