How to avoid bad breath after brushing your teeth

Updated on September 9, 2014

The primary cause of bad breath is the bacteria that build up on the back of your tongue or in between your teeth. These bacteria excrete acidic substance which cause tooth decay by destroying the hard tissues of the mouth and corroding with your teeth which gives you a bad breath. But for the bacteria to survive in you mouth it needs to be fed. And by starving it, you can inhibit its spread and thus control your mouth odor.

Drink water

- Always keep your mouth moist by drinking lots of water. This ensures that you have enough saliva which protects both hard and soft oral tissues from reacting with the acidic substance excreted by the bacteria.

- After a meal, swish water around your mouth for a few seconds. This will loosen food particles stuck between your teeth and clean your mouth. No food for the bacteria.

- If you drink alcohol, ensure you take water in between to wash out the sugars. Beer is fermented and contains lots of sugars.

Eat Fruits

Fruits hydrate your body and ensure your mouth does not get dry. Tooth decay is as a result of increase of acid in your mouth that react with your teeth. Eating fruits ensure you have saliva in you mouth to neutralize acid in your mouth and hence prevent cavity and bad smell.

Brush the molars

Brush at least twice a day, for at least 2 minutes and make sure to cover all the areas in your mouth. Especially focus on where the teeth meet the gum. When you brush your teeth ensure you thoroughly clean the molars to combat plaque buildup and help keep teeth and gums healthy. The remains of plaque may be the reason why you can still smell a bad odor coming out of your mouth even after brushing. Also, failure to clean you molars well will leave some food particles stuck on your teeth.

Avoid sugary snacks

- If you have to eat sweets and snacks, go for those that will clear from your mouth quickly. Lollipops, cookies, cakes or other desserts contain a high amount of sugar which will stick in your mouth. Bacteria feeds on these sugars. Instead, choose dentally healthy foods such as nuts, raw vegetables, plain yogurt, cheese and sugarless gum. For instance if you chew sugar free gum after meals it will help rinse harmful acid off your teeth to help you preserve tooth enamel. Also most sugar free gums contain xylitol, a substance that inhibit the growth of oral bacteria.

- Limit intake of starches made from white flour: these are simple carbohydrates and can linger in your mouth and then break down into simple sugars. A good way is to eat them as part of your meal, instead of by themselves, when mixed together they easily neutralize the acid in your mouth.

- Avoid carbonated soft drinks since they contain phosphorous which wear away the enamel. And if you do so, use a straw to avoid much contact with the teeth.

Keep your mouth closed

When you breath through your mouth, it becomes dry making it more conducive for bacteria to breed even after you have cleaned your mouth.
