What Causes a Bad Taste to Occur?
Should you develop a bitter or bad taste in your mouth, it is important that you know most causes are not life-threatening or even what you would consider “serious.” However, the symptoms can leave you with an unpleasant and irritating problem that won’t go away until it’s properly treated.
But why does it happen in the first place? If it’s not soured milk or pungent food causing the problem, it might be due to:
- Dry Mouth – If your mouth is unable to produce enough saliva because of medications you’re taking, poor oral hygiene, or the use of tobacco products, it can become dry and serve as a haven for bad bacteria to grow and spread. As a result, you can develop a bad taste in your mouth.
- Poor Oral Hygiene: If you are not cleaning your teeth and gums as you should, cavities, an abscess, or even gum disease can form, resulting in a bad taste in your mouth.
- Pregnancy: It’s not uncommon for pregnant women to get a bitter taste in their mouths. The reason is due to fluctuating hormones and typically dissipates after giving birth.
- Oral Thrush: Unpleasant to look at and experience, these white spots occur on the tongue as a result of a yeast infection within the mouth that can create a bitter taste and may need treatment from your dentist or physician.
Other reasons you may be developing a bad taste in your mouth include taking certain medications, experiencing GERD or acid reflux, undergoing cancer treatment, menopause, stress and anxiety, and even nerve damage.
Ways to Prevent It in the Future
One of the most effective ways to keep from experiencing a bad taste in your mouth is to remember to maintain good oral hygiene. Bad bacteria is known for causing many serious oral health conditions, so making sure you are brushing with fluoride toothpaste twice a day as well as flossing at least once and rinsing with an antimicrobial mouthwash can help eliminate causes of gingivitis and tooth decay.
It’s also important to talk to your physician about the symptoms you’re experiencing if you are taking certain medications or vitamins (i.e., zinc, iron, copper). And don’t forget to keep your regular six-month checkups and cleanings with your dentist to ensure there is no build-up of plaque and tartar on your teeth.
If the bitter taste lasts for multiple days and will not go away no matter how much you brush your teeth or chew sugar-free gum, it’s time to seek the help of a professional.
By drinking plenty of water, eliminating bad lifestyle habits, and staying on top of your oral healthcare each day, you can minimize your chances of developing a bitter taste in your mouth, and instead enjoy your daily life.
