How your diet can help
If your oral hygiene is good but you still experience bad breath, the answer might lie in what you are eating. Poor diet and lifestyle habits can contribute to unpleasant breath. Strong foods such as garlic, onions, fish, too many dairy products, as well as beverages such as alcohol and coffee are major culprits. Foods that are high in fat, as well as sugary foods and refined (white) carbs also contribute towards the breeding of bad bacteria in the mouth. Gargling with salt water could help you, as it removes leftover food particles and bad bacteria.
Eating fruits which are high in vitamin C can help prevent bad breath, as they reduce levels of bacteria in the mouth. Including apples in your diet is great for reducing plaque, as apples clean the surface of the teeth as you bite into them. Fennel seeds can help combat bad breath alongside being a good digestive remedy. Incorporate them into curries and salads, or chew them after meals. Fennel tea is great option if you do not like the seeds. Parsley is a potent natural deodoriser, so garnishing your meals with parsley may help if you experience bad breath. Parsley is also delicious added to smoothies and juices.
Alternately you could chew on a small amount after meals. Chewing small amounts of ginger root, or sipping a ginger tea, can help deodorise your mouth and wash away bad bacteria. The problem could also lie past the mouth and down in your gut. Poor or sluggish digestion contributes to bad breath. Ensure you are eating plenty of fibre, which keeps the gut healthy by encouraging the fast elimination of toxins.
