Periodontal Disease: Warning Signs, Health Risks, and Prevention

When people think about oral health, they usually focus on their teeth. Far less attention is given to the gums, even though healthy gums play a critical role in supporting healthy teeth and overall wellness.

The challenge is that periodontal disease, commonly known as gum disease, often develops quietly. Unlike many dental problems, it may not cause pain in its early stages, allowing damage to occur before patients realize anything is wrong.

Nico Geurs, D.D.S., M.S., a periodontist and oral health expert with UAB Dentistry, says bleeding gums are one of the earliest warning signs people should never ignore.

“Gum disease or periodontal disease tends to not be associated with overt signs that are alarming to the patient,” Dr. Geurs said. “Pain is not associated with periodontal disease, and the signs that it does have are often minimized.”

Common signs and symptoms of gum disease

Many patients assume occasional bleeding while brushing or flossing is normal. It is not.

“If your gums bleed when you brush, that is a sign of an inflammatory disease around your teeth that needs to be evaluated and possibly treated,” Dr. Geurs said.

Other signs of periodontal disease can include:

• Bleeding gums
• Gum recession
• Persistent bad breath
• Loose teeth
• Sensitive teeth
• Deep pockets around teeth

Because these symptoms often develop gradually, patients may overlook them until the disease has progressed.

How periodontal disease can lead to tooth loss

Periodontal disease affects more than the gum tissue surrounding the teeth.

As inflammation progresses, it can destroy the bone and supporting structures that hold teeth in place. Deep pockets begin to form around the teeth, creating an environment where harmful bacteria can thrive.

“It’s important just from the perspective of keeping the tooth,” Dr. Geurs said.

Without treatment, periodontal disease remains one of the leading causes of tooth loss in adults.

The connection between gum disease and overall health

Researchers have identified associations between periodontal disease and several systemic health conditions. While these relationships continue to be studied, evidence suggests that oral inflammatory burden and oral microbial burden may influence overall health.

“There are correlations between oral inflammatory burden and oral microbial burden with an established impact on the progression of cardiovascular disease,” Dr. Geurs said.

This growing body of research reinforces the importance of maintaining healthy gums as part of a comprehensive approach to health.

Gum disease during pregnancy

Oral health is especially important during pregnancy.

Geurs notes that studies have shown women with periodontitis face a significantly increased risk of preterm birth.

“It was established that if you have periodontitis during pregnancy, your odds for delivering preterm goes up,” he said.

His research has also examined oral health disparities in underserved communities, where access to professional dental care during pregnancy may be limited.

“We found that it’s feasible to improve oral health if the patient just knows they have to do this and are given the tools so they can learn to do it,” Dr. Geurs said.

These findings underscore the importance of education, preventive care, and regular dental visits during pregnancy.

The best ways to prevent periodontal disease

Despite advances in dental technology and treatment, the most effective prevention strategy remains remarkably simple.

“The basic treatment is for patients to keep their teeth plaque-free, and that’s done at your home,” Dr. Geurs said.

Daily brushing and cleaning between the teeth help remove the bacterial plaque that contributes to inflammation and gum disease.

Routine dental visits allow providers to identify problems early and recommend treatment before significant damage occurs.

Why daily oral hygiene matters

Patients often hope there is a mouth rinse, medication, or quick solution that can replace daily oral hygiene.

Dr. Geurs says that solution does not currently exist.

“There’s really no alternative to good oral hygiene at this point,” he said.

Dental professionals can diagnose disease, provide treatment, and recommend strategies for success, but long-term gum health depends largely on daily habits at home.

“We’re merely there to understand the issues, and guide and help them,” Dr. Geurs said. “But if they don’t treat it, then our efforts are going to almost be in vain.”

How dental visits support overall health

Modern dentistry increasingly considers the relationship between oral health and overall health.

During routine dental visits, providers may identify signs and symptoms that warrant further medical evaluation. Dental teams can also work alongside physicians and other health care providers to support a patient's overall well-being.

“We’re trying to be a partner with patients not just in their oral health, but also to look at the aspects that intersect between oral health and overall health,” Dr. Geurs said.

Because many patients visit their dentist more frequently than their physician, dental appointments provide valuable opportunities for early detection.

“The mouth is often a mirror for the rest of the body to help screen for diseases that patients may not know they have,” he said.

Protect your gums for lifelong oral health

Gum disease is one of the most common oral health conditions, yet it often develops without obvious symptoms. Bleeding gums, gum recession, persistent bad breath, and loose teeth should never be ignored.

The best defense against periodontal disease remains simple: brush twice daily, clean between your teeth every day, and schedule regular dental checkups. These habits can help protect your gums, preserve your teeth, and support your overall health for years to come.
