Gum disease affects nearly half of adults aged 30 and over in the United States, according to the CDC. That makes it more common than diabetes and almost as common as heart disease.
But here is a question most people ask, can you catch gum disease from someone else?
In this blog, you will learn whether gum disease is contagious, how it can spread, who is at risk, and what you can do to protect your oral health.
Gum disease is not directly contagious, but the bacteria that cause it can spread through saliva. Protect your oral health with strong hygiene, regular dental cleanings, and early care for every person in the household.
What Is Gum Disease?
Gum disease is a bacterial infection that affects the soft tissue and bone supporting your teeth. It is the most common form of gum disease and a major cause of tooth loss in adults.
It begins as gingivitis, marked by red, swollen gums that bleed easily. If left untreated, it progresses to periodontitis, where the gum pulls away from the tooth, forming pockets that trap harmful bacteria. Over time, this leads to gum recession, bone loss, and loose teeth.

Common signs of gum disease include:
- Bleeding gums during regular brushing or flossing
- Persistent bad breath and dry mouth
- Gum recession exposing tooth roots
- Sensitive teeth or uncomfortable chewing
- Loose teeth or loss of teeth
- Pus between gum tissue and teeth
So, Is Gum Disease Contagious?
Gum disease itself is not a contagious disease, but the bacteria responsible for it can spread from person to person through saliva contact.
Bacteria that contribute to gum infection, such as Porphyromonas gingivalis, travel in saliva.This means sharing food utensils, kissing, or close contact can transmit the oral bacteria that lead to the development of gum disease.
While this does not guarantee infection, the risk of gum disease increases in those with poor oral hygiene routines or other risk factors.
How Can Gum Disease Spread?
Transmission occurs when bacteria responsible for periodontal disease move from one person’s mouth to another. This path of infection is especially common in families or couples.
Ways gum disease bacteria can spread:
- Kissing or saliva contact: Bacteria travels in saliva, making disease through kissing a concern for those with active gum disease.
- Sharing utensils or drinks: Cups, forks, and spoons can transfer bacteria and food particles.
- Parents to children: Cleaning pacifiers or blowing on food introduces oral bacteria.
Bacteria thrive on food debris left behind by inconsistent dental hygiene. The buildup of plaque allows oral bacteria to advance through the stages of gum disease.
Who Is Most at Risk for Contracting Gum Disease?
The spread of gum disease is more likely when combined with individual health conditions and poor oral hygiene habits.
Risk factors include:
- Irregular or poor oral hygiene routines
- Smoking and dry mouth
- Diabetes or other health issues affecting immune response
- Pregnancy or hormonal changes
- Genetic predisposition to oral diseases
Preventive Strategies for Families and Couples
You cannot isolate yourself, but you can prevent the spread of gum disease bacteria by improving oral hygiene and reducing shared exposure.
Strategies to reduce risk of infection:
- Do not share toothbrushes, straws, or cups.
- Brush and floss daily. Effective dental hygiene lowers plaque buildup.
- Attend regularly a dentist for checkups to detect early symptoms of gum disease.
- Treat active gum disease quickly. Synchronize care within households.
- Support gum health with a healthy diet and reduced acidic foods.
Can Gum Disease Come Back After Treatment?
Without proper maintenance, harmful bacteria can return, especially if close contacts still have untreated gum diseases.
Stages of gum disease may regress or reappear after scaling and root planing or gum graft procedures if plaque is not controlled.
