Gum disease is the leading cause of tooth loss in adults worldwide — and it is largely preventable and treatable when identified early. Periodontics is the dental specialty dedicated to the health of the gum tissue, bone, and other supporting structures that hold the teeth in place. At Al Safwa Medical Center in Bani Yas, Abu Dhabi, the periodontics department manages the full spectrum of gum and bone health — from early gingivitis and professional deep cleaning to advanced periodontal surgery, bone grafting, and gum contouring for cosmetic purposes.
This guide explains what periodontal disease is, how it progresses, what the available treatments involve, and when each is appropriate. Whether you have been told you have gum disease, are noticing bleeding when you brush, or are planning a dental implant that requires bone preparation, understanding periodontal health is essential to long-term oral and systemic wellbeing. A detailed overview of the stages and warning signs of gum disease is available in the guide to gum disease stages.
What is periodontal disease and how does it develop?
Periodontal disease (gum disease) is a bacterial infection of the structures supporting the teeth — the gum tissue, periodontal ligament, and the alveolar bone in which the teeth are anchored. It begins as gingivitis — inflammation of the gum tissue caused by plaque accumulation at the gumline — and can progress to periodontitis if left untreated, where the infection extends below the gumline and begins to destroy the bone and tissue attachment around the roots of the teeth.
The defining clinical feature of periodontitis is the formation of periodontal pockets — deepened spaces between the tooth and the surrounding gum tissue where bacteria accumulate in an environment that is impossible to clean with a toothbrush. As the pockets deepen, bone loss progresses, teeth become mobile, and eventually the support is insufficient to retain them. The World Health Organization identifies severe periodontitis as the sixth most prevalent disease globally, affecting nearly 20% of the world’s population.
Risk factors for gum disease
The primary cause of periodontal disease is bacterial plaque that is not adequately removed. Beyond this, several systemic and lifestyle factors significantly increase susceptibility or severity:
Smoking and tobacco use. The most significant modifiable risk factor for periodontal disease. Smoking reduces blood flow to the gum tissue, suppresses the immune response to bacterial infection, and masks the classic signs of active disease — smokers tend to bleed less on probing despite having more severe disease than non-smokers.
Diabetes. Uncontrolled blood glucose creates a pro-inflammatory environment that accelerates periodontal breakdown. The relationship is bidirectional — periodontal disease makes blood glucose control harder, and poorly controlled diabetes worsens gum disease.
Genetics. Some individuals have a genetic predisposition to more aggressive inflammatory responses to periodontal bacteria, meaning they develop more severe disease despite comparable levels of plaque control.
Medications. Certain drugs — calcium channel blockers, anti-epileptic medication, immunosuppressants, and some oral contraceptives — cause gum overgrowth or increase gum susceptibility to inflammation.
Signs and symptoms of gum disease
Early gum disease (gingivitis) is often entirely painless, which is why many patients are unaware they have it. The most common signs that warrant a dental assessment include:
Bleeding when brushing or flossing — the single most common early warning sign that the gum tissue is inflamed. Healthy gums do not bleed during normal home care. A thorough explanation of causes of gum bleeding and treatment options covers this in detail. Swollen, puffy, or red gum tissue. Bad breath that persists despite good oral hygiene — bacteria in deep periodontal pockets continuously produce volatile sulphur compounds. Gum recession — teeth that appear longer than before as the gum tissue pulls away from the tooth surface. Tooth sensitivity along the gumline where root surfaces have become exposed. Loose or mobile teeth — a late sign indicating significant bone loss. Pus visible at the gumline. Changes in how the teeth fit together when biting.
Periodontal treatments at Al Safwa Medical Center
Gum disease treatment and deep cleaning
Gum disease treatment at Al Safwa begins with a comprehensive periodontal assessment — probing depths are measured at six points around every tooth, bleeding on probing is recorded, gum recession is documented, and radiographs are assessed for bone level. This provides a clinical map of disease severity and extent before treatment begins.
The primary non-surgical treatment for periodontitis is deep cleaning — subgingival debridement (also called scaling and root planing) — which removes bacterial deposits from root surfaces within the periodontal pockets. This is performed under local anaesthesia and is typically divided into quadrant-by-quadrant sessions. The pocket depth should reduce measurably after professional debridement as the gum tissue heals and re-attaches. Follow-up assessment at six to eight weeks confirms the response to treatment and determines whether further intervention — periodontal surgery — is needed.
Bone grafting
Bone grafting is used both as a periodontal surgical procedure — to restore bone lost to periodontal disease in select defect morphologies — and as a preparatory procedure before dental implant placement in patients who have insufficient bone volume at the implant site. Bone graft material (which can be synthetic, processed bovine, or from the patient’s own bone) is placed at the defect site and covered with a membrane to guide bone regeneration while preventing soft tissue from growing into the space.
The detailed guide to bone grafting in Abu Dhabi explains when it is needed before implants, how the procedure works, and what recovery involves. The relationship between bone grafting and implant planning is also covered in the dental implants guide.
Gingivectomy (cosmetic gum surgery)
Gingivectomy refers to the surgical removal of excess gum tissue. It is used both therapeutically — to reduce enlarged gum tissue that creates deep pockets and traps bacteria, often caused by medications or genetic overgrowth — and cosmetically, to rebalance an asymmetric or excessively gummy smile as part of a Hollywood Smile plan. When performed for cosmetic purposes, gingivectomy raises the gumline to expose more of the tooth crown, improving the visible tooth-to-gum ratio and creating a more proportional smile frame for veneers or other restorations placed subsequently.
How periodontal health connects to overall health
The connection between periodontal disease and systemic health has been increasingly well-established in clinical research over the past two decades. Active periodontal disease creates a chronic bacterial and inflammatory burden that can affect conditions beyond the mouth. The associations most consistently reported in research include:
Cardiovascular disease. Periodontal bacteria enter the bloodstream through inflamed gum tissue and have been identified in atherosclerotic plaques. Chronic periodontal inflammation is associated with elevated systemic inflammatory markers. PubMed hosts extensive peer-reviewed research confirming the association between periodontal disease and cardiovascular risk.
Diabetes. As noted above, the relationship is bidirectional — treating periodontal disease can improve glycaemic control in patients with type 2 diabetes.
Preterm birth and low birth weight. Several studies have identified an association between active periodontal disease during pregnancy and adverse pregnancy outcomes. Dental assessment and treatment of active gum disease during pregnancy is considered safe and appropriate.
These systemic associations do not mean periodontal disease causes cardiovascular disease or diabetes directly — but they do reinforce the clinical position that periodontal health is not a cosmetic or minor concern, but a genuine component of overall health management.
Periodontal maintenance: keeping gum disease from returning
Once periodontal disease has been treated, the maintenance phase is essential to prevent recurrence. Patients with a history of periodontitis are more susceptible to relapse than patients who have never had the disease — because the pocket architecture, even after successful treatment, remains slightly deeper than in periodontally healthy patients. Three- to four-monthly professional cleaning appointments are typically recommended for patients who have completed active periodontal treatment, rather than the standard six-monthly interval.
Home care remains critical — thorough brushing twice daily, daily interdental cleaning (floss or interdental brushes), and tongue cleaning to reduce the overall bacterial load in the mouth. Smoking cessation, where applicable, has a greater impact on long-term periodontal stability than almost any other single intervention.
Looking for periodontal treatment in Abu Dhabi?
At Al Safwa Medical Center in Bani Yas, Abu Dhabi, the periodontics team provides a full clinical assessment of gum and bone health before recommending treatment. The assessment determines whether professional cleaning alone is sufficient, whether deep cleaning is needed, or whether more advanced periodontal procedures are indicated. Treatment is staged appropriately — there is no clinical value in beginning cosmetic or implant work on a foundation of uncontrolled gum disease.

Frequently asked questions
Is gum disease reversible?
Gingivitis — early gum disease limited to inflammation of the gum tissue without bone loss — is fully reversible with professional cleaning and improved home care. Once bone loss has occurred (periodontitis), the destroyed bone does not fully regenerate through treatment alone. However, periodontitis can be effectively arrested and stabilised so that further bone loss does not occur. Early treatment is the key to the best long-term outcome.
How do I know if I have gum disease?
The most common early signs are bleeding gums during brushing or flossing, persistent bad breath, swollen or tender gum tissue, and visible gum recession. Many patients with established periodontitis have no pain until the disease is advanced. A clinical periodontal assessment including gum pocket measurements and radiographs is the only reliable way to diagnose and stage gum disease. If you have noticed any of the signs described, a dental examination is the appropriate next step.
What is deep cleaning and is it painful?
Deep cleaning (subgingival debridement or scaling and root planing) removes bacterial deposits from root surfaces within periodontal pockets, below the gumline. It is performed under local anaesthesia so the procedure itself is not painful. Some soreness and sensitivity are normal for a few days afterwards. Most patients find it significantly more comfortable than they anticipated. The detailed guide to deep cleaning in Abu Dhabi covers the procedure in full.
Can gum disease affect my overall health?
Yes. Active periodontal disease creates a chronic inflammatory and bacterial burden that is associated with increased risk of cardiovascular disease, contributes to difficulty controlling blood glucose in patients with diabetes, and is associated with adverse pregnancy outcomes. Treating and maintaining periodontal health is part of managing overall health, not simply oral health. Your general physician may be relevant to the discussion if you have systemic conditions that interact with gum disease.
Do I need healthy gums before getting dental implants?
Yes. Active gum disease is a contraindication for implant placement. The same bacteria that destroy the bone supporting natural teeth can attack the tissue around implant posts — a condition called peri-implantitis. Gum disease must be treated and stabilised before any implant placement begins. At Al Safwa, the periodontal assessment is a routine part of every implant planning process.
