Can I have gum disease without knowing it?

Yes. Gum disease is often called a "silent" disease because it can progress without causing significant pain. Many people do not realize they have it until a dentist measures their gum pockets or detects bone loss on an X-ray. This is one of the main reasons regular dental exams are so important — early detection allows for much simpler treatment.

Is bleeding when I brush always a sign of gum disease?

Bleeding gums are one of the most common early signs of gum disease (gingivitis), but they can also result from brushing too hard or using a hard-bristled toothbrush. If your gums bleed consistently when you brush or floss, it is worth having a dentist evaluate them. Healthy gums should not bleed with normal brushing.

What is a gum pocket, and what is a normal measurement?

A gum pocket is the space between the tooth and the surrounding gum tissue. Dentists measure pocket depth with a small probe during a periodontal exam. Healthy pockets are typically 1–3 mm. Pockets of 4 mm or more indicate gum disease, and deeper pockets suggest more advanced periodontitis.

Can gum disease cause bad breath?

Yes. Persistent bad breath (halitosis) that does not improve with brushing and mouthwash is a common sign of gum disease. The bacteria that cause gum disease produce sulfur compounds that create an unpleasant odor. If bad breath is a recurring problem, a dental evaluation is recommended.

How is gum disease diagnosed?

Gum disease is diagnosed through a clinical examination that includes measuring gum pocket depths, assessing gum color and texture, checking for bleeding, and reviewing dental X-rays to evaluate bone levels. Your dentist or hygienist will classify the disease by stage and grade to determine the appropriate treatment.

Quick Answer

The most common signs of gum disease are bleeding gums when you brush or floss, red or swollen gums, persistent bad breath, and gum recession. In more advanced stages, teeth may feel loose or shift position. Because gum disease is often painless in its early stages, regular dental exams are the most reliable way to detect it.

How Gum Disease Is Diagnosed

Gum disease is diagnosed through a periodontal exam. Your dentist or hygienist uses a small probe to measure the depth of the pockets between your teeth and gums. Healthy pockets are 1–3 mm. Pockets of 4 mm or more indicate disease, and deeper pockets suggest more advanced periodontitis.

Dental X-rays are also used to assess bone levels around the teeth. Bone loss is a hallmark of periodontitis and is not visible during a visual exam alone. Together, pocket measurements and X-rays give a complete picture of gum health.
