Halitosis, more commonly known as bad breath, is a very common condition that can affect people of all ages. Occasional bad breath is normal, especially after eating strongly flavoured foods such as garlic or onions, but persistent bad breath may indicate an underlying oral health problem.
For many people, halitosis can affect confidence, social interactions, and quality of life. Fortunately, in most cases, bad breath can be improved with appropriate dental care and oral hygiene habits.
