What is Periodontitis?

It has likely happened to you before: you’re brushing your teeth in front of the mirror and, as you spit, you notice a trace of blood. Or perhaps you’ve noticed your gums looking redder than usual. We often ignore these signs, thinking they will “just go away” or that we’ve simply brushed too hard. However, what your mouth is trying to tell you could be much more important than it seems.

Today, we’re going to talk straight about a condition that affects millions and is the leading cause of tooth loss in adults: periodontal disease, commonly known as gum disease.

While the name sounds technical, understanding what is happening in your mouth is the first step toward protecting your smile for the long term. It’s not just about aesthetics; it’s about your health. We’re going to break down the essentials clearly and simply so you know what to look for and what to do.

What is Periodontitis? Causes and Symptoms

Periodontitis is a deep infection of the gums that damages the soft tissue and destroys the bone that supports your teeth. If left untreated, it can lead to loose teeth and eventually tooth loss.

It starts as gingivitis, a superficial inflammation of the gums caused by bacterial plaque. If gingivitis isn’t treated, the infection becomes chronic and spreads deeper until it turns into periodontitis.

Unlike gingivitis, bone damage caused by periodontitis is irreversible. Once bone support is lost, it does not grow back on its own. That is why the earlier you detect the problem, the better your chances of stopping the process and saving your teeth.

Causes of Periodontitis

Periodontitis doesn’t appear overnight. It is the result of several factors that create the perfect environment for bacteria to damage your gums and bone.

Bacterial Plaque and Tartar

The primary cause is the accumulation of plaque due to insufficient oral hygiene. The mouth is home to millions of bacteria. These, along with food particles, form a sticky film on the teeth called plaque or oral biofilm.

Brushing and flossing remove plaque. If it isn’t removed, it hardens and forms tartar (dental calculus). Tartar acts as a shield for bacteria; it cannot be removed by daily brushing, and only a professional cleaning can clear it away.

Risk factors that accelerate the process

In addition to bacteria, there are factors that can speed up the progression of the disease:

• Smoking: This is the most significant risk factor. Smoking weakens the immune system, reduces blood flow to the gums, and hinders healing. Furthermore, it often masks bleeding, allowing the disease to progress without you noticing.
• Genetics: If you have a family history of tooth loss due to gum problems or bone loss, you may have a higher predisposition.
• Systemic diseases: Diabetes, for example, worsens periodontitis and makes it harder to control. Conversely, periodontitis also makes blood sugar management more difficult.
• Hormonal changes: Pregnancy, menopause, or puberty can alter how the gums react to bacteria.
• Medications: Some drugs can reduce saliva flow or cause gum overgrowth (gingival hyperplasia), favoring plaque buildup.
• Stress and habits: Chronic stress and poor dietary or hygiene habits worsen the body’s response to infection.

Symptoms of Periodontitis

Periodontitis is known as a “silent disease” because it rarely hurts in its early stages. This causes many people to delay seeing a dentist. Even so, your body gives off signals: learn how to recognize them.

Visible signs in your daily life

Swollen or puffy gums that are bright red or purplish—rather than a healthy pink—are a classic sign. Bleeding when you brush, floss, or bite into hard foods indicates that something is wrong.

Another common symptom is persistent bad breath (halitosis) or an unpleasant taste in the mouth. This is caused by bacterial activity in the periodontal pockets, which generates foul-smelling compounds.

Changes in tooth structure

As the disease progresses, teeth may appear longer because the gums are receding, leaving the roots exposed. “Black triangles” or gaps between teeth that weren’t there before may also appear.

In advanced stages, you will notice tooth mobility. If you feel a tooth move when touched or while chewing, or if your bite changes, it is a sign that the bone support is compromised.

How to tell if I have periodontitis

Self-examination helps, but it is no substitute for a professional check-up. If you identify with several of the symptoms mentioned, some degree of periodontal disease is likely present. The only way to know for sure and determine the severity is through a clinical periodontal study.

The importance of periodontal probing

To diagnose periodontitis, professionals use a periodontal probe. This is a small millimeter ruler gently inserted between the tooth and the gum. In a healthy mouth, the depth is 1 to 3 millimeters. If the probe goes deeper than 4 millimeters and there is bleeding, it indicates the presence of periodontal pockets and suggests that bacteria are actively destroying the bone.

In addition to probing, X-rays are taken to evaluate bone loss around each tooth. This “map” of the mouth (periodontogram) is essential for designing the right treatment.

If you suspect something is wrong, don’t let it slide. Time works against your supporting bone. The best course of action is to see a specialist who can evaluate your case. If you are looking for an accurate diagnosis and effective treatment, having a good periodontist in Madrid can make the difference between keeping your teeth or losing them.

When to see a dentist

See your dentist if you notice frequent bleeding, “tender” or receding gums, loose teeth, changes in your bite, or persistent bad breath. You should also go if you have risk factors like diabetes or if you smoke. Early detection prevents more aggressive and costly treatments.

Connection to general health

Periodontitis doesn’t just affect the mouth. There is evidence that periodontal bacteria and inflammation can influence systemic health. There is a two-way relationship with diabetes: diabetes worsens periodontitis, and periodontitis makes blood sugar harder to control.

Gum disease has also been associated with an increased risk of cardiovascular problems and pregnancy complications. That’s why taking care of your gums is taking care of your entire body.

Treatments to stop the disease

The good news is that periodontitis can be treated. The primary goal is not always to recover lost bone, but to stop the infection to prevent further loss of support. In specific cases, regenerative techniques exist, but infection control is the foundation.

Basic treatment: Scaling and root planing

The first step is usually non-surgical treatment, known as “deep cleaning” or scaling and root planing. This involves cleaning deep below the gum line to remove tartar and bacteria from the periodontal pockets, and smoothing the root surface to encourage the gum to reattach.

If the pockets are very deep or access is difficult, periodontal surgery may be necessary to lift the gum, clean the bone, and reposition the tissue. In cases of severe bone loss, guided tissue regeneration or bone grafts are applied depending on the case.

Complementary therapies

In addition to mechanical therapy, there are adjuvant treatments such as the controlled use of local or systemic antibiotics, antimicrobial gels or specific rinses, and even lasers in certain protocols. The recommendation depends on the diagnosis and individual risk.

The maintenance phase: The key to success

Once treatment is complete, periodontal disease requires lifelong maintenance. It is a chronic condition similar to diabetes or hypertension: it is not enough to treat it once and forget about it.

Periodontal patients must attend check-ups and cleanings every 3, 4, or 6 months, depending on their risk. If you let your guard down and return to poor hygiene habits or stop attending check-ups, bacteria will re-colonize the pockets and the destruction will start again.

Daily prevention: An effective routine

Prevention is your most powerful tool. A proper daily routine significantly reduces the risk of things getting worse:

• Brush at least twice a day using the correct technique and a soft or medium-bristled brush.
• Use dental floss and interproximal brushes daily, especially if you already have spaces between your teeth.
• Include a chlorhexidine rinse or specific mouthwashes recommended by your dentist if you have active inflammation.
• Control risk factors: quit smoking, manage diabetes, reduce stress, and maintain a balanced diet low in sugar.
