Did you know that what happens in your mouth impacts the health of your entire body? Healthline shares more on the relationship between gum health and heart health:

Gum disease (aka periodontal disease) is inflammation of the gums. It can lead to the breakdown of the gums, teeth, and bone tissues that hold them in place. Gum disease may increase the risk of heart disease because inflammation in the gums and bacteria may eventually lead to the narrowing of important arteries (heart disease).

Here is a closer look at the inflammation link from Harvard

"Periodontal disease increases the body's burden of inflammation," says periodontist Dr. Hatice Hasturk of the Harvard-affiliated Forsyth Institute. Acute inflammation — which involves an outpouring of immune cells that attack irritants and microbial invaders — fosters healing over the short term. But long-term (chronic) inflammation is a key contributor to many health problems, especially atherosclerosis.

Let essential oils assist in your oral routine so you can naturally eliminate harmful bacteria and inflammation in the mouth and gums. Making your own mouthwash with essential oils is a simple way to put them into action. Homemade mouthwash also costs less than most commercial preparations.

How to Use Essential Oil Mouthwash

When using essential oils in mouthwash, use caution with hot oils like oregano, cinnamon, clove, and thyme. Start with one drop, stop using if mouth irritation occurs. You can dilute hot essential oils first with a teaspoon of virgin coconut oil before adding to warm water if needed.

Use mouthwash 2-3 times per day after brushing your teeth. Remember to mix well right before use because oil and water don't mix. I prefer not to use any additives when I make my DIY mouth rinses so the mixtures will separate.

Homemade mouthwash can also be used for cleaning your toothbrush. Just fill up a shot glass and place brush bristles down into the mixture. Let soak for 30 minutes. Use this method for mouth guards and retainers too.

Other good oral habits include:

  • Be sure to drink plenty of water and to avoid sugary drinks
  • Floss at least once per day (removes debris and plaque between teeth)
  • Refrain from smoking or chewing tobacco
  • Chew only sugar-free gum to stimulate saliva and reduce plaque
  • Use mouthwash regularly
  • Eat a healthy diet with vegetables, high-fiber foods, and low-sugar fruits
  • Practice tongue scrapping (using a special tool to clean tongue)
