Level 3
Many patients find that their bad breath is managed by using treatments or self-help tips from levels one and two but there are a few patients that have such severe symptoms that nothing seems to work for them.
For these people bad breath affects their everyday activities and relationships so much that it has a detrimental impact on their life.
If level one and two products have not been successful they would need to try a treatment that works by neutralising the sulphur compounds. If you have a patient that requires a level 3 treatment for halitosis then you will need to refer them to the pharmacist.
