Did you know that gum disease typically involves multiple stages, the first one being gingivitis? Although this is the mildest form of the infection, it usually involves some inflammation, redness, and bleeding—all of which can worsen if left untreated for too long. Would it surprise you to know that it can present a risk to others around you? Keep reading to learn how contagious gingivitis can be and ways to protect your smile in the long run.

Is it Possible for Gingivitis to Spread to Others?

Similar to most other forms of infection, gingivitis can also spread from your mouth to others. The bacteria that settles around your smile can start to weaken and attack the soft oral tissues, causing bleeding and inflammation along the gum line. Of course, the germs can easily move from you to another, which can happen through:

  • Kissing
  • Sharing a toothbrush or other oral hygiene tools
  • Sharing cups, forks, spoons, or other utensils (especially with a baby)

According to the American Dental Association, bacteria from gingivitis most easily spreads from mothers to their children, specifically if the parent currently presents signs of the disease. The same can be said for couples who live together and share certain products or even food.

Tips for Preventing Gingivitis

Avoiding the spread of gingivitis involves more than simply not sharing your food or personal utensils. Some of the best ways to protect your smile include:

  • Visiting your dentist every six months for dental checkups and cleanings allows them to clear out plaque and tartar that can develop into gum disease.
  • Eating nutritious foods that promote good saliva production and gut health helps you reduce bacteria accumulation.
  • Looking for oral hygiene products that specifically fight against gum disease.
  • Refraining from sharing toothbrushes or other products with your partner or spouse.
  • Encouraging your significant other to get treatment if they show signs of gingivitis.

While gum disease can be problematic, it can also be reversed with proper care! Keep the above tips in mind, and you’ll set yourself up for success with a healthier smile in the long run.
