Periodontitis: early symptoms and warning signs

Periodontosis, medically known as periodontitis, is an inflammatory condition that can progressively damage the gums, ligaments and bone that support the teeth. The early signs may seem easy to overlook: a little bleeding when brushing, redder gums or recurring bad breath.

These symptoms do not in themselves confirm a diagnosis of periodontitis, but they do indicate that the gums need to be assessed. Identifying inflammation before tooth mobility sets in can limit damage to the supporting tissues and help preserve your natural teeth.

Periodontitis: symptoms at a glance

Signs that may indicate a gum or periodontal problem include:

• bleeding gums when brushing, using interdental cleaners or chewing;
• red, swollen or tender gums;
• persistent bad breath;
• receding gums and teeth that appear ‘longer’;
• tooth sensitivity, particularly in areas where the roots have become exposed;
• the appearance of new gaps between the teeth;
• discharge between the gums and teeth;
• a change in the way the teeth meet when biting
• tooth mobility.

According to the European Federation of Periodontology, bleeding, gum recession, bad breath and tooth mobility are among the main signs that require professional assessment. Some of these may have other causes, which is why a diagnosis should not be made solely on the basis of symptoms observed at home.

The colloquial term ‘periodontosis’ is frequently used to describe periodontitis. This is an inflammatory condition affecting the tissues that support the teeth: the gums, the periodontal ligaments and the alveolar bone. Unlike gingivitis, the inflammation is no longer confined to the gums alone, but also affects the deeper structures that support the teeth.

The process usually begins with the build-up of bacterial biofilm on the surface of the teeth and along the gum line. The body’s inflammatory response can gradually lead to the gums pulling away from the teeth, the formation of periodontal pockets and the slow destruction of the supporting bone.

What is the difference between gingivitis and periodontitis?

Gingivitis and periodontitis are not the same thing. Gingivitis affects the gums and is reversible when bacterial plaque is controlled through proper oral hygiene and professional treatment. Periodontitis involves the loss of supporting tissues – the alveolar bone and periodontal ligaments – and the damage that has already occurred cannot be reversed by brushing alone. Treatment can, however, control the inflammation and halt or, at worst, slow down the progression of the disease.

Why can periodontitis go unnoticed?

Periodontitis can progress without obvious pain. The American Academy of Periodontology describes periodontal disease as often being ‘silent’, as clear symptoms may only appear in more advanced stages.

Furthermore, some changes are easily dismissed as normal:

• bleeding is put down to brushing too vigorously;
• bad breath is temporarily masked by mouthwash;
• gum recession is regarded as a cosmetic issue;
• slight mobility may not be noticed straight away.

In people who smoke, bleeding may be less obvious, even if the condition is present. The absence of bleeding does not, therefore, rule out a periodontal problem.

“Bleeding gums are not normal, even if they only occur when brushing your teeth. They are often one of the first signs of inflammation and a reason to have your gums checked before the condition progresses and affects the tissues that support your teeth.” – Dr. Codruța Ciurescu

Bleeding gums

Bleeding whilst brushing, flossing or when biting into hard foods is one of the most common signs of gum inflammation.

Healthy gums should not bleed repeatedly when brushed correctly. If bleeding occurs frequently, spontaneously or is accompanied by redness and swelling, a dental consultation is recommended.

Do not stop brushing the area just because your gums are bleeding. Gentle cleaning should continue, but the cause of the bleeding must be assessed by a dentist.

Red, swollen or sensitive gums

Gingivitis is the superficial and reversible form of the condition. The gums may become red, swollen, shiny or sensitive, and may bleed easily.

Not all cases of gingivitis progress to periodontitis. However, persistent gingivitis indicates that the inflammation is not under control and that improved oral hygiene and professional removal of bacterial deposits are required.

Halitosis

Persistent bad breath, known as halitosis, can be associated with the build-up of bacteria on the tongue, between the teeth and in periodontal pockets. Bacteria are most often responsible for this unpleasant odour.

However, halitosis has several possible causes, including dry mouth, tooth decay, certain infections or general medical conditions. If the odour returns quickly after brushing and cleaning the tongue, a dental check-up is recommended.

Sensitivity to cold, heat, sweet or sour foods

Tooth sensitivity is not a specific or definitive sign of the onset of periodontitis. It can occur when the gums recede and part of the tooth root remains exposed.

Gum recession may be associated with periodontal disease, but it can also have other causes, such as aggressive brushing, the position of the teeth or thin gum tissue. Your dentist can distinguish between localised recession and changes caused by periodontitis. 

The symptoms observed by the patient do not always accurately indicate the stage of the disease. Staging is determined through clinical examination and radiological investigations, based on the loss of attachment, bone loss, the depth of the pockets and the complexity of the case.

Book an appointment if you notice repeated bleeding of the gums, swollen gums, persistent bad breath, receding gums or changes in the position of your teeth.

You should not wait until you experience pain before seeking an assessment. Book an appointment as soon as possible if you notice:

• loose teeth;
• pus or other discharge between the gum and the tooth;
• severe swelling;
• a change in your bite;
• difficulty chewing;
• new gaps between the teeth.

These signs do not automatically mean that a tooth will be lost. However, they do indicate the need for a diagnosis and a treatment plan.

What happens during a periodontal consultation?

The assessment may include:

• a discussion about symptoms, medical history, smoking, diabetes and any treatments you are currently undergoing;
• an examination of the gums and any plaque and tartar build-up;
• measuring the depth of the periodontal pocket, which corresponds to bone loss around the tooth, using a periodontal probe;
• recording bleeding on probing;
• assessment of gingival recession;
• checking tooth mobility and position;
• assessing how the teeth fit together when biting;
• X-rays to assess the supporting bone, where indicated;
• determining the diagnosis, stage and risk of progression.

At DENT ESTET, the assessment can be carried out using the Florida Probe digital system, which allows for the computerised recording of periodontal measurements and their comparison throughout the course of treatment.

“In periodontitis, the aim of treatment is to control inflammation and preserve natural teeth for as long as possible. Long-term results depend on both treatment tailored to each individual case and good daily oral hygiene, together with regular follow-up.” — Dr. Codruța Ciurescu

Treatment for periodontitis is tailored to the stage of the disease, the depth of the periodontal pockets, individual risk factors, and how the tissues respond to the initial stages of treatment.

According to the EFP clinical practice guideline for the treatment of stage I–III periodontitis, treatment follows a stepwise approach:

1. Plaque control and management of risk factors

Patients receive personalized guidance on toothbrushing and interdental cleaning. Risk factors such as smoking and diabetes are addressed, along with factors that contribute to plaque build-up.

2. Subgingival instrumentation

Bacterial deposits and calculus are removed from the root surfaces and periodontal pockets using hand and/or ultrasonic instruments.

3. Re-evaluation

After a period of healing, the dentist reassesses pocket depth and bleeding. If disease remains active in certain areas, further non-surgical treatment or periodontal surgery may be recommended.

4. Supportive periodontal care

Once the disease has been brought under control, regular follow-up appointments are required at intervals determined by the patient’s individual risk. These visits help prevent recurrence and maintain the results of treatment.

Antibiotics are not routinely recommended for all patients with periodontitis. They may be considered in selected cases based on the diagnosis and the dentist’s clinical assessment.

Professional periodontal treatment does not replace good oral hygiene at home. Long-term stability depends on daily plaque removal, effective management of risk factors, and regular follow-up appointments.

The early signs may be subtle. It is important to recognise them.

Bleeding when brushing, swollen gums or persistent bad breath should not be ignored, even if there is no pain. These symptoms can have various causes, and a consultation is the only way to find out whether the inflammation is limited to the gums or has also affected the tissues supporting the teeth.

If you notice any changes to your gums, book a periodontal consultation. A timely diagnosis allows for the selection of a treatment tailored to the stage of the disease and ensures the long-term protection of your natural teeth.
