Root canal therapy has an unfairly bad reputation. Some people mistakenly believe that it is very painful, while others believe that it is associated with an increased disease risk. Nothing could be further from the truth! In fact, root canal therapy is a surprisingly comfortable treatment that can preserve damaged teeth. And, research indicates that this procedure can actually support your overall wellness. How does it do so? Continue reading to find out.

Groundbreaking Research about the Link Between Root Canal Treatment and Overall Health

A study conducted in England looked at 65 adults who underwent root canal treatment. The participants all had their blood drawn before their procedure and afterward at the 3-month, 6-month, 12-month, and 24-month marks. The researchers looked at 40 biomarkers that are linked to risks for heart disease and diabetes.

What were the results? The researchers found that the participants exhibited better blood sugar control, healthier cholesterol levels, and lower inflammation (a major risk factor of heart disease).

Why Does Root Canal Therapy Make a Difference?

The participants’ improved health after their dental treatment is no mere coincidence. Scientists have known for years that poor oral health is strongly linked to overall health risks, including issues like diabetes, heart disease, and more. Often, this has to do with how oral bacteria can sneak into the bloodstream and increase the body’s overall burden of inflammation.

Root canal treatment addresses a tooth infection at its source. All of the diseased tissue is removed from the tooth, and the tooth is filled with an inert material to help it maintain its structure. After the procedure, the body no longer has to constantly fight the infection, which translates to less inflammation and improved metabolic biomarkers.

What Does This Mean for You?

Of course, it would be best to prevent dental infections from occurring in the first place. That is why you should keep up with good oral hygiene, visit your dentist for routine care, and avoid harmful habits like smoking.

However, if you do end up developing a tooth infection, it is important to listen to your dentist’s treatment recommendation. It is possible they will have to remove the tooth if it is badly damaged. Or, if they suggest that you undergo root canal therapy, you can commit to the procedure with confidence that it will benefit both your smile and your head-to-toe wellness!
