An oral health issue that may be more widespread than you think is gum disease. It’s estimated that half of U.S. adults over 30 have some form of it. This condition’s early stage is known as gingivitis, which causes inflamed and noticeably red gums. With how prevalent it may be, you may wonder if it’s contagious. Here’s what you need to know and how you can protect your smile.

How Can Someone Get Gingivitis?

Gingivitis occurs when you have an infection in the soft tissues of your mouth. This can happen if you have a buildup of bacteria and plaque along your gumline. It attacks the pink soft tissues, making them swell and become red. Many people often experience bleeding when brushing and flossing. You may be at a higher risk of developing it if you have poor oral hygiene, smoke, or overindulge in sugar.

So, Is Gingivitis Contagious?

Technically speaking, gingivitis itself isn’t contagious. However, that doesn’t mean that the bacteria that cause it aren’t. It’s possible for them to spread if you exchange saliva with someone who has it. For instance, if you have it, then actions such as sharing drinks, utensils, toothbrushes, and even kissing can increase the other person’s risk of it. This is especially true if they have poor oral hygiene themself.

What Can I Do to Avoid Developing Gingivitis?

The good news is that preventing gingivitis can be an easy feat! One of the best ways you can do it is by having good dental hygiene. By brushing twice and flossing once a day, you can remove bacteria along your gumline. Rinsing out with an antibacterial mouthwash can help ensure you get as much harmful plaque as possible.

You may also consider breaking bad habits, such as using tobacco. Chewing or smoking it can increase your risk of inflammation and gingivitis. Not only that, but following a balanced diet can also be fruitful. By eating foods that support your body and oral health, your immune system can be more effective in fighting off infections.

In the end, an easy thing you can do is visit your dentist. Through routine checkups and cleanings, they can look out for early warning signs of gum disease. If they find any red flags, then you can get the treatment you need. That way, it doesn’t progress into its more advanced stages and keeps your smile strong and problem-free.
