Periodontal disease is a bacterial infection of the gums and bone that support your teeth. It starts with plaque buildup along the gum line and, if left untreated, can destroy the tissue and bone holding teeth in place. According to the NIDCR, 42.2% of adults over 30 in the United States have some form of periodontitis, and 7.8% have the severe form. The good news is that early-stage gum disease is completely reversible, and even advanced cases can be managed with professional treatment. This article explains what periodontal disease is, how it progresses, the warning signs to look for, and how we treat and help prevent it at our Southwest Houston office.
How Periodontal Disease Affects Your Gum Health
Periodontal disease affects your gum health by triggering a cycle of inflammation, tissue breakdown, and bone loss around the teeth. It begins when bacteria in dental plaque irritate the gum tissue, causing redness, swelling, and bleeding. According to the NIH’s StatPearls medical reference, gingivitis, the earliest form of gum disease, affects up to 90% of the population at some point in their lives. At this stage, no bone loss has occurred and the condition is fully reversible with proper care.
When plaque is not removed through brushing, flossing, and professional cleanings, it hardens into tartar (calculus) that cannot be removed at home. Bacteria then migrate below the gum line, forming pockets between the teeth and gums. As these pockets deepen, the infection destroys the connective tissue and bone that anchor the teeth. This is periodontitis, and it is the leading cause of tooth loss in adults according to the NIDCR.
We see patients across Southwest Houston who had no idea they had gum disease until the condition had already advanced. Periodontal disease is often painless in its early stages, which is why routine dental exams are so important.
Regular checkups allow us to measure pocket depths, check for bone loss, and catch problems early. Our preventive dental care program is designed to help patients avoid gum disease before it starts.
The Stages of Gum Disease
Gum disease progresses through distinct stages, each more serious than the last. Recognizing which stage you may be in helps determine the right treatment approach.
Gingivitis
Gingivitis is the mildest form of gum disease. It causes red, swollen gums that may bleed during brushing or flossing. There is no bone loss at this stage. According to the CDC, gingivitis is largely preventable and treatable with a combination of good home care and professional cleanings. A thorough dental cleaning followed by consistent brushing and daily flossing is usually enough to reverse gingivitis completely.
Mild to Moderate Periodontitis
When gingivitis is left untreated, it can progress to mild and then moderate periodontitis. At this stage, bacteria have moved below the gum line and started to damage the bone and connective tissue. Gum pockets deepen to 4 to 5 millimeters (a healthy pocket measures 1 to 3 millimeters). According to a study published in the Journal of Dental Research, 30% of U.S. adults over 30 have moderate periodontitis. Treatment at this stage typically involves scaling and root planing, a deep cleaning procedure that removes plaque and tartar from below the gum line and smooths the root surfaces so the gums can reattach.
Severe Periodontitis
Severe periodontitis involves significant bone loss, deep pockets of 6 millimeters or more, tooth mobility, and possible tooth loss. The NIDCR reports that 7.8% of U.S. adults over 30 have severe periodontitis. At this stage, treatment may include more aggressive deep cleanings, antibiotic therapy, and in some cases, tooth extraction to prevent infection from spreading to neighboring teeth and bone.
Warning Signs of Periodontal Disease
Many people with gum disease do not realize they have it because the early stages are usually painless. The CDC recommends watching for these warning signs: red, swollen, or tender gums; gums that bleed when you brush or floss; gums that have pulled away from your teeth; persistent bad breath or a bad taste in your mouth; loose or shifting teeth; changes in how your teeth fit together when you bite; and changes in how a partial denture fits.
If you notice any of these symptoms, schedule an appointment promptly. The earlier gum disease is caught, the more treatment options are available. Patients in the Houston area can call our office at 713-668-1600 for a same-day evaluation.
Severe or sudden gum pain, swelling, or bleeding may indicate an acute infection that needs immediate attention. Our team provides emergency dental care for urgent gum and tooth problems.
Risk Factors That Increase Your Chance of Gum Disease
Certain factors make some people more likely to develop periodontal disease than others. According to the CDC and the American Academy of Periodontology, the major risk factors include smoking and tobacco use, diabetes, poor oral hygiene, age, genetics, hormonal changes (such as during pregnancy), certain medications that reduce saliva flow, and conditions that weaken the immune system.
Smoking is the single most significant modifiable risk factor. The CDC reports that 62% of current smokers over 30 have periodontitis, compared to about 25.6% of nonsmokers. People with diabetes are also at much higher risk. The NIDCR found that 59.9% of adults who self-reported diabetes had periodontitis.
