Large cavities and progressive gum disease both provide perfect hiding spots for large collections of bacteria. As cavities worsen, bacteria accumulate in actual holes in the teeth. When gum disease progresses, deep pockets develop between the tooth’s roots and the surrounding gum and jawbone. The deep pockets are breeding grounds for bacteria that become more dangerous as the pocket deepens.
When choosing a mouthwash for fresh breath, it is important to look for certain ingredients. Antiseptic ingredients like essential oils or chlorhexidine can kill bacteria that cause bad breath. Fluoride can help prevent cavities and strengthen teeth. Alcohol-free mouthwashes are gentler on the mouth and do not contribute to dry mouth, which can worsen bad breath.

Foods that are sticky or have a high sugar content, such as candy or dried fruit, can contribute to the formation of tonsil stones. These foods can stick to the tonsils and provide a breeding ground for bacteria.
Remember, brushing and using mouthwash can only offer temporary relief in case the patient suffers from chronic halitosis caused due to other illnesses.
