For most people, having bad breath is a common problem that often impacts how they feel about themselves and how they communicate or interact with friends, coworkers, and family. The foods that can be the cause of bad breath are listed below.

Foods that Can Cause Bad Breath

1. Coffee and Tea

Certain foods can decrease mouth moisture, providing sustenance for odour-causing bacteria. Balancing them in your diet, while adding flavour, can be challenging for your breath. Taste buds may not thrive on a breath-friendly diet.

Coffee and tea, both notorious for drying the mouth and their strong scents, are daily staples in the UK. In fact, Britons consume 165 million cups of tea daily, equivalent to 20 Olympic swimming pools!

Eliminating both could reduce the risk of bad breath, though your morning ritual may not see significant improvement. After your coffee, consider a glass of water to rinse your mouth and restore moisture.

2. Alcohol

Alcohol, with its high sulphite content, is known to be a beverage that can contribute to bad breath. Its potent drying effect provides an environment conducive for harmful bacteria to thrive. Consider opting for water, tea, or coffee as alternatives and minimize alcohol consumption whenever feasible to maintain fresh breath.

8 Foods That Can Cause Bad Breath3. Garlic

While garlic adds richness to curries, spaghetti sauces, and more, it’s a known culprit for causing bad breath. Its strong aroma can persist, even entering the bloodstream and exiting through the lungs, making the taste linger for days after consumption, impacting your breath long after the meal.

4. Protein

You may have noticed that enjoying dishes like spaghetti bolognese, wine, and coffee isn’t the best choice for fresh breath. While protein itself doesn’t have a noticeable odour, it can trigger processes leading to bad breath. When your protein intake is significantly higher than fats and carbohydrates, the body converts excess protein into energy through ketosis, producing ketones with a strong odour that brushing or flossing can’t eliminate.

However, reducing your protein intake may not be feasible or advisable depending on your dietary needs, so prioritising overall health is crucial. One way to mitigate the effects of a high-protein diet is by increasing your water intake, which can help freshen your breath.

5. Onions

Due to their high sulphur content, consuming onions can lead to unpleasant breath originating from both the mouth and the lungs. Consequently, thorough mouth washing may only tackle part of the problem.

6. Canned Fish

While opting for canned fish like tuna makes for a convenient and speedy lunch choice, it’s important to note that it often results in bad breath. The fish begins to oxidize within the can, emitting an odour that can linger in your mouth even after your midday meal.

7. Sugar

Sugar is an ideal fuel for the bacteria responsible for bad breath. While gum chewing can help keep your mouth moist, it’s essential to choose sugar-free gum; otherwise, you’re simply feeding the germs!

8. Highly Acidic Foods

Foods with high acidity, such as sauerkraut, tomatoes, blueberries, and grapes, create an environment favoured by harmful bacteria. While fruits and vegetables are crucial for a balanced diet, acidic ones can harm dental health. This highlights an important concern: an oral-friendly diet may not meet overall nutritional needs due to the exclusion of certain foods and nutrient imbalances.

Foods that can prevent bad breath

Foods that may prevent bad breath1. Herbs

Oils found in parsley, basil, and mint can all temporarily cover up other less pleasant smells.

2. Apples

You may significantly reduce your risk of developing bad breath if you can replace acidic foods with apples.

Apples act as a natural mouthwash by breaking down the substances that cause bad breath.

Melons are another excellent fruit choice because of their high vitamin C content, which not only controls bacteria but also helps in the prevention of gum disease and gingivitis.

3. Greens

By balancing internal PH levels, spinach fights bad breath.

As well as spinach, foods like kale, lettuce, and cabbage may all help in the fight against bad breath.

4. Water

By preventing the bacteria of a dry mouth, where they thrive, drinking plenty of water helps to keep your mouth hydrated and saliva levels high. Moreover, water will wash away food odour-causing particles.

Other potential underlying issues for bad breath

Besides food, bad breath can also be caused by various underlying issues, including:

  1. Poor Oral Hygiene: Inadequate brushing, flossing, and tongue cleaning allow bacteria to thrive in the mouth, leading to foul-smelling breath.
  2. Gum Disease: Gingivitis and periodontitis can produce bad breath due to bacterial infection and inflammation of the gums.
  3. Dental Issues: Tooth decay, cavities, and abscesses can release odour-producing bacteria, contributing to bad breath.
  4. Dry Mouth: A lack of saliva can result in a dry mouth, making it easier for bacteria to cause bad breath. Dry mouth can be caused by medications, medical conditions, or mouth breathing.
  5. Tongue Coating: Bacteria and food particles can accumulate on the tongue’s surface, forming a white or yellow coating that emits odour.
  6. Tobacco Use: Smoking and tobacco products can lead to bad breath, as well as increase the risk of gum disease and oral cancers.
  7. Diet: Consuming pungent foods like garlic, onions, and certain spices can result in temporary bad breath. Additionally, crash diets and fasting can cause an unpleasant odour.
  8. Medical Conditions: Some systemic illnesses, such as diabetes, respiratory infections, and liver or kidney disease, can produce bad breath as a symptom.
  9. Sinus and Respiratory Issues: Postnasal drip and sinus infections can lead to bad breath due to the buildup of mucus and bacteria in the throat.
  10. Dentures and Orthodontic Appliances: Bacteria can accumulate on dentures, braces, and other dental appliances, causing bad breath if not cleaned properly.
  11. Alcohol and Mouthwash: Overuse of alcohol-based mouthwashes and certain medications containing alcohol can contribute to dry mouth and worsen bad breath.

A great practice, all of the staff are lovely, including the receptionists, who are welcoming. I had some surgery done on my cervical spine the week before my visit and still had the stitches in across my throat, anhway the dentist made me feel relaxed and did the check up without having to tilt my head back, it was harder for her to do the routine heck that way but she was adamant I wasn't tilting my head back due to my surgery. The dentists and dental nurses I have had the pleasure to meet so far, make you feel totally relaxed, I used to dread going to the dentist but it's now a positive experience and I have regular check ups every 6 months, something I never did before as I hated going to a dentist. So I'm very happy with this practice and highly recommend them to anyone requiring to register with a dentist, or needs treatment and is afraid of the dentist!
