Signs of gum disease: what to watch for
Gum disease often develops without pain. Knowing the early signs means catching it when it’s easiest to treat.
What gum disease looks and feels like
This is the most common early sign. Healthy gums don’t bleed. If yours do, it means they’re inflamed, typically because bacteria has built up at or below the gumline.
Healthy gum tissue is firm and pink. Inflammation changes both the color and texture.
Bacteria below the gumline produce odor that doesn’t resolve with brushing. If bad breath keeps returning despite good home care, gum health is worth evaluating.
• Early signs (gingivitis)
• Bleeding when you brush or floss
• Gums that look red, swollen, or puffy
• Persistent bad breath
• Signs of more advanced disease (periodontitis)
Gums pulling away from the teeth
Recession exposes more of the tooth root. Once gum tissue pulls back, it doesn’t grow back, though the disease can still be stopped.
Teeth that feel loose or have shifted
Bone loss affects the support structure. Looseness is a later-stage sign.
Pockets forming between teeth and gums
These are measured at your dental exam. Pockets deeper than 3mm indicate the disease has moved below the gumline.
Pus between teeth and gums
A sign of active infection.
Increased sensitivity to hot and cold
Receding gums expose root surfaces, which are more sensitive than enamel.
A change in your bite
If teeth that once fit together feel different, bone loss may have caused shifting.
Bleeding when you brush is not normal
The most common reason patients delay seeking care is the belief that some bleeding is just part of brushing. It’s not. Healthy gums don’t bleed.
Bleeding gums mean the tissue is inflamed. Inflammation is the body’s response to bacteria that have settled at or below the gumline. The bleeding itself is a signal, and the earlier it’s addressed, the simpler the treatment: gingivitis is still reversible before it progresses to periodontitis.
What causes gum disease
The direct cause is bacterial plaque, the sticky film that forms on teeth between cleanings. When plaque isn’t fully removed, it hardens into tartar (calculus), which forms at and below the gumline. Tartar can only be removed with professional instruments. The bacteria in tartar trigger the inflammation that becomes gum disease.
Several factors affect how quickly the disease develops or how severe it becomes:
Genetics. Some people are significantly more prone to gum disease regardless of home care habits.
Smoking and tobacco use. Smoking is one of the strongest risk factors for gum disease and makes treatment less effective.
Diabetes. Poorly controlled blood sugar increases inflammation throughout the body, including the gums.
Dry mouth. Saliva helps control bacteria. Medications that reduce saliva flow increase gum disease risk.
Hormonal changes. Pregnancy, puberty, and menopause can all increase gum sensitivity and susceptibility.
When to book an evaluation
If you’ve noticed any of the signs above, book an exam rather than waiting to see if they resolve. Gum disease doesn’t improve on its own. The bacteria need to be removed professionally for the inflammation to calm down.
If you haven’t had a dental exam in more than a year, it’s also worth scheduling one regardless of symptoms. Gum disease is often painless until it’s progressed significantly, and an exam is the only reliable way to assess pocket depths and bone levels.
Our office is in Seattle, open Monday through Thursday, with straightforward scheduling by phone or online.
