How Much Caffeine is Too Much?

How Much Caffeine is Too Much? - Lubricity

Caffeine is a large part of many people’s day. Coffee can be an essential part of someone’s morning routine or even soda during dinnertime. While caffeine may seem like an integral portion of the day, too much caffeine can affect your overall health. Moreover, typically when we think of caffeine, we initially think of coffee, but caffeine is in many different beverages. 

How Much is Too Much?

It is important to be aware of your caffeine intake. Generally, about 400mg of caffeine per day is safe for most adults. This is equivalent to about 4 cups of coffee per day. If you are consuming more than this amount, you probably have experienced a jittery feeling or even dry mouth symptoms.  

In addition, energy drink or energy shot consumption has been increasing over the past few years. In general, energy drinks contain more concentrated caffeine than coffee, tea, or soda. This can be harder to keep track of because generally, there are higher levels of caffeine in energy drinks. 

Overconsumption of caffeine may lead to caffeine intoxication resulting in tachycardia, vomiting, cardiac arrhythmias, and seizures.

Side Effects of Too Much Caffeine

Drinking too much caffeine may have negative side effects. It is always important to speak with a medical professional about any problems you are experiencing, but some effects of too much caffeine may be: 

  • Insomnia 
  • Jittery feeling 
  • Irritability 
  • Muscle tremors 
  • Frequent bathroom breaks 
  • Headache 
  • Fast heartbeat 
  • High blood pressure 
  • Bad breath or halitosis 
  • Dry mouth 

What is Dry Mouth?

Dry mouth is a medical condition known as xerostomia. Xerostomia can be caused by medical and non-medical reasons, but regardless, causes inadequate saliva production. Consequently, this creates a dry, uncomfortable feeling in the oral cavity. Some causes of dry mouth symptoms are:

Connection Between Caffeine & Dry Mouth

Many of us do not consider the effects our morning coffee may have on us. However, it is the overconsumption of caffeine we need to be cautious about. Too much caffeine can have negative side effects such as irritability, insomnia, etc. as previously stated above.  

Dry mouth as a result of caffeine is usually caused by the presence of tannins. Tannins are categorized as an astringent that when consumed, may create a dry, puckering feeling within the mouth. Tannins are located in coffee, tea, red wine, and fruit. 

Too much caffeine may lead to a large increase in tannins, hence the cause of dry mouth symptoms. This is why tracking caffeine intake is crucial to avoid dry mouth symptoms.  

Dry Mouth Problems

While dry mouth symptoms may be uncomfortable, there may be larger problems that arise. Unfortunately,  these symptoms may lead to larger systemic health issues. The health issues may range from oral and systemic. Some dry mouth problems are:

  • Poor dental hygiene
  • An increase in plaque
  • Tooth decay
  • Gum disease
  • Oral thrush 
  • Altered, or metallic taste
  • Poor nutrition as a result of discomfort while eating

Alleviate Dry Mouth Symptoms

If you are consuming too much caffeine, this should be easier to fix than some of the other causes of dry mouth. So, first and foremost, begin limiting your caffeine intake. It may be beneficial to switch out your typical coffee with a decaffeinated version for you initially or make sure you’re reducing your normal cups of caffeinated coffee.  

Some other ways to alleviate dry mouth symptoms are to stay hydrated, use a humidifier, or avoid mouthwashes with alcohol. Registered Dental Hygienist and Teeth Chatters Podcast Host Sara Juliano also recommends utilizing a tongue scraper to remove excess plaque and reduce the risk for halitosis.
