How we help
We look for gum disease, decay and areas where food collects, and clean the teeth and gums thoroughly. You will also get simple advice on cleaning the tongue and between the teeth at home.
Frequently asked questions
Will mouthwash cure bad breath?
Mouthwash only masks the smell for a short time. Treating the cause, such as gum disease or tartar, gives lasting results.
Can bad breath come from somewhere other than the mouth?
Occasionally, from the sinuses, throat or stomach. If your mouth is healthy, we will advise you on seeing a doctor.
