If you have a bad taste in your mouth, then you might do what you can to get rid of it. You may try drinking water to wash it away, or chewing some gum or mints. These may offer some relief, but why is it happening? Some reasons may not be too much of a problem, while others can turn into a dental emergency! Keep reading to learn four possible causes for the bitter taste you’re experiencing.

1.)  Poor Dental Hygiene

When you wake up in the morning, is that when you notice this unpleasant symptom? A reason behind it may stem from your oral health habits! What you may be tasting is a buildup of bacteria in your mouth. To get rid of it, you can try to brush and floss. Be sure to do them twice a day and don’t forget to scrub your tongue! Rinse with an antibacterial mouthwash to get as much plaque as you can.

Not only that, but you are also lowering your risk of cavities and gum disease by doing this. If you have any, then they can only continue to worsen until they are treated by your dentist. When left to their own devices, they can even spiral into a dental emergency!

2.)  Dry Mouth

For some individuals, they may have dry mouth. This is when you don’t produce enough saliva. It’s not good news because you won’t be able to effectively wash away harmful bacteria.

The cause of this condition can be a few different things, so you may have to do some digging to find out what’s true for you. It can happen because of medications, smoking, autoimmune diseases, or even just natural aging. Be sure to drink plenty of water to keep your mouth hydrated.

3.)  Acid Reflux

This condition is when your stomach contents get backed up into your esophagus. It’s generally temporary, but it’s called gastroesophageal reflux (GERD) if it’s longer-lasting and chronic. You may also have a burning sensation in your abdomen and chest. That being said, it’s often the most common cause of a bitter taste in your mouth.

4.)  Certain Medications and Supplements

This symptom may come as a side effect of some medicines and vitamins. When they are being absorbed, bits of them can find their way into your saliva and cause this symptom. If you notice that it’s often intense and persistent, then you can consider talking to your physician about how to stop it or if anything else can be done.

Although you may have this unpleasant taste in your mouth, bringing it up to your dentist can help ensure it’s not a problem with your oral health. That way, you can narrow down the possibilities and get the relief you deserve.
