How Dental Problems Can Increase Your Risk of Heart Attack and Stroke

dental problemsAs medical science and technology continue to advance, we are beginning to see more how problems in one area of the body can have massive effects on other areas that don’t seem at all related. Proclaiming that the body is an interconnected system might seem almost silly because it’s such an obvious fact, but 20-30 years ago, most people wouldn’t have thought that problems with the teeth or gums could increase one’s risk for heart disease, heart attack, or hemorrhagic stroke.

Understanding the connection between the mouth, the bloodstream, and one’s overall health depends on understanding how dental and gum problems develop, and their ultimate results. In this post, we’ll be discussing:

  • The stages of dental decay and how it could increase one’s risk of stroke
  • The stages of gum disease and how it could increase one’s risk of heart attack

Dental Decay

dental problemsAs with almost all dental problems, dental decay begins with plaque. This is the sticky, fuzzy substance that accumulates on your teeth when you go long periods of time between brushing.

Plaque is the result of a combination of carbohydrates from the food that you eat, and the bacteria that naturally lives in your mouth. The combination of the two results in an acid, which later builds up with further food particulates to become a thick, sticky film.

This is why foods that are rich in carbohydrates – sugary and starchy food, most notably – increase your risk of dental decay.

This is how the dental decay progresses:

  • Plaque builds up on the teeth.
  • The acid in the plaque begins to eat away at the tooth enamel, the protective layer surrounding the teeth. At this stage, you won’t feel any pain, and the tooth enamel can actually be replenished later on if the process is stopped and reversed through dental cleanings and proper dental hygiene. However, if left untreated, the acid in plaque will begin to eat away at the next layer.
  • As the acid begins wearing down the dentin (the white, bony part of the tooth), a hole begins to develop. When that happens, you officially have a cavity. This is where it starts to hurt, and your tooth may become sensitive to hot and cold temperatures as well as pressure. At this stage, a dental filling is usually the most appropriate solution.
  • If the cavity problem is not solved, the acid will eventually make its way into the pulp – the soft tissue underneath the dentin which contains the tooth nerve. Because the acid in plaque is also filled with bacteria, the tooth pulp eventually becomes infected and begins to swell. However, because the swelling is suppressed by the surrounding dentin, the pressure gets focused downward onto the tooth root and the blood vessels that supply the tooth with nutrients. At this stage, the tooth begins to die. The pain levels at this stage are also incredibly painful. The solution to this problem is usually a root canal.
  • Abscess – this is the culmination of dental decay, at least at the level of the mouth. An abscess is an inflamed pocket of pus (containing acid and bacteria from plaque) that forms at or around the tooth nerve. Often this manifests as a pimple-like protuberance at the gum line next to the infected tooth. This is the most painful stage. Your dentist can pierce the abscess and relieve the pressure, then he or she can perform a root canal and cover up the tooth with a dental crown.

For a long time, we used to believe that the problems began and ended at the level of the teeth and gums. However, research suggests that the bacteria involved in dental decay can make its way from the gumline directly into the bloodstream. From the bloodstream, the bacteria from the infection can make its way to the various blood vessels in the body.

Now, consider that a hemorrhagic stroke is the result of a rupture in the blood vessels of the brain, which causes internal bleeding. Also note that the main bacteria that correlates with hemorrhagic stroke is the Streptococcus mutans bacteria, and studies have shown that those who have suffered hemorrhagic stroke contained higher amounts of Streptococcus mutans in their saliva. Furthermore, this specific kind of bacteria is also associated with cerebral microbleeds.

Periodontal Disease

dental problemsPeriodontal disease is often referred to simply as “gum disease” and the two names are essentially synonymous. However, it is often mistakenly referred to as “gingivitis” or “periodontitis”. So, before we move on, let’s define our terms:

  • Periodontal disease – a disease of the gums, synonymous with “gum disease”
  • Gingivitis – the beginning stages of periodontal disease
  • Periodontitis – a stage of periodontal disease that’s advanced beyond gingivitis

As with dental decay, periodontal disease is caused by plaque. Specifically, it’s the result of plaque making its way into and underneath the gumline. This is why it’s imperative to massage the gumline as you brush your teeth in order to clear out plaque that could be lingering on it.

If left to accumulate on the gums, the body responds to plaque by releasing a hormone that causes the gums to become inflamed. This inflammation is often painful and causes the gums to bleed easily. This is the early stage of periodontal disease called gingivitis, and can be treated and reversed with dental cleanings and good dental hygiene.

If left untreated, gingivitis can progress into full on periodontitis, an advanced stage of gingivitis in which the gums loosen from the teeth (due to the inflammation) and recede away from the teeth and the tooth roots. This often results in tooth loss. Periodontitis is technically reversible, although it is more difficult than reversing gingivitis.

As we’ve seen above with tooth abscesses, the gumline has a direct root to the bloodstream, and from there, to various vessels of the body, including the arteries of the heart. Consider that heart disease is a matter of plaque building up on the interior walls of heart.

Inflammation is also a common factor in heart disease, and is one of the main factors of concern when it comes to periodontal disease as well. As time goes on, more and more evidence is beginning to reveal the connection between periodontal disease and heart disease.

Contact Your Dentist for Dental Cleanings and Other Services

A major part of proper dental hygiene is making regular appointments with your dentist for check ups, cleanings, and other services that you need to stop, reverse, or treat dental decay and periodontal disease. It’s always better to solve these problems early on, as it is easier and less expensive to treat than in later stages of development.
