Signs You Might Need a Periodontist: Gum Disease Explained for Markham Patients

Most people know that brushing and flossing protects their teeth. Far fewer realise that the same habits — or the absence of them — are what stand between them and one of the most common and most serious dental conditions in Canada: gum disease.

Approximately 80% of Canadians over the age of 45 have some form of periodontal disease, and roughly one in five of those people have no idea. Gum disease progresses silently in its early stages — and by the time most patients notice significant symptoms, it has already caused damage that cannot be fully reversed.

This guide explains what gum disease actually is, how to recognise the early warning signs, what the difference is between gingivitis and periodontitis, and when Markham patients should see a periodontist versus staying with their regular family dentist.

What Does a Periodontist Do?

A periodontist is a dental specialist who focuses exclusively on the prevention, diagnosis, and treatment of periodontal disease — more commonly known as gum disease — and on the placement of dental implants. After completing a standard four-year dental degree, a periodontist undertakes an additional two to three years of specialised postgraduate training focused entirely on the gum tissue, alveolar bone, and the structures that support the teeth.

In practical terms, a periodontist handles cases that go beyond what a general dentist can

treat effectively. Their scope of practice includes:

• Diagnosing and staging all forms of periodontal disease

• Non-surgical treatments including deep cleaning (scaling and root planing)

• Surgical procedures including flap surgery, pocket reduction, and guided tissue regeneration

• Gum grafting to treat significant recession

• Bone grafting to restore lost jawbone density

• Dental implant placement

• Treatment of gum problems related to systemic conditions such as diabetes

For Markham patients with mild gum concerns — early-stage gingivitis, occasional bleeding gums at routine visits — a family dentist or dental hygienist is the appropriate first point of contact. A periodontist becomes necessary when the disease has progressed beyond what routine care can manage, or when a general dentist determines that specialist-level intervention is needed.

At Hwy7 Family Dentistry, we monitor gum health at every routine visit. If we identify signs that require specialist-level periodontal care, we will coordinate the referral and work alongside the periodontist throughout your treatment.

Gingivitis vs Periodontitis: Understanding the Difference

Gum disease exists on a spectrum. Understanding where you are on that spectrum determines what treatment you need — and how urgently.

Gingivitis — The Reversible Stage

Gingivitis is the earliest stage of gum disease and the only stage that is fully reversible. It occurs when plaque — the soft, sticky bacterial film that forms on teeth within minutes of cleaning — is not removed consistently. As plaque builds up along and beneath the gumline, the bacteria within it release toxins that inflame the surrounding gum tissue.

At the gingivitis stage, the infection is confined entirely to the gum tissue. The bone and connective tissue supporting your teeth have not yet been affected. This is critically important: with professional cleaning and improved home care, gingivitis can be completely reversed, and your gums can return to full health.

Signs of gingivitis:

• Gums that bleed during brushing or flossing — even if only occasionally

• Gums that appear redder or more puffy than usual

• Mild persistent bad breath (halitosis)

• Gums that feel tender to the touch

The challenge with gingivitis is that many people normalise these signs. They assume that bleeding gums are simply a consequence of brushing too hard, or that bad breath is a diet issue. In reality, healthy gums do not bleed during routine brushing. Any consistent bleeding is a signal that the gum tissue is inflamed and that bacterial infection is present.

Periodontitis — When Gingivitis Is Left Untreated

If gingivitis is not addressed, the infection progresses beneath the gumline into the bone and connective tissue that anchor the teeth in the jaw. This is periodontitis — a more serious condition that, unlike gingivitis, cannot be fully reversed. It can be managed and controlled, but the bone and tissue loss it causes is permanent.

As periodontitis advances, the gums begin to pull away from the teeth, creating deepened spaces called periodontal pockets. These pockets trap bacteria and debris that ordinary brushing and flossing cannot reach, creating an environment that accelerates the disease process. Over time, the supporting bone deteriorates, the teeth become mobile, and — without treatment — tooth loss follows.

Signs of periodontitis:

• Visibly receding gumline — teeth appear longer than before

• Deep gum pockets around teeth (measured by your dentist with a small probe)

• Persistent bad breath that does not resolve with brushing

• Teeth sensitivity to temperature — particularly cold

• Loose or shifting teeth

• Changes in how your teeth fit together when biting

• Pus between the teeth and gums

• Pain when chewing

The Royal College of Dental Surgeons of Ontario (RCDSO) classifies periodontitis as an urgent dental condition that warrants same-visit assessment when symptoms are active. If you are experiencing any combination of the above symptoms in Markham, do not wait for your next scheduled routine appointment — call Hwy7 Family Dentistry at (905) 604-1995 to arrange an assessment.

7 Early Warning Signs You Should Never Ignore

The earlier gum disease is identified, the less invasive and more effective the treatment. Here are the seven signs that warrant a dental assessment — even if you feel no pain.

1. Bleeding Gums During Brushing or Flossing

This is the single most common early sign of gingivitis — and the most frequently dismissed. Healthy gum tissue does not bleed during routine oral hygiene. Occasional light bleeding after flossing an area you have neglected for a while may resolve with consistent daily flossing. Persistent or recurrent bleeding is different — it signals active bacterial infection in the gum tissue and should always be assessed professionally.

2. Persistent Bad Breath (Halitosis)

Bad breath that does not resolve after brushing, flossing, and tongue cleaning is one of the hallmark signs of gum disease. The sulphur compounds produced by the bacteria living in infected gum pockets and beneath the gumline create a distinctly unpleasant odour that no amount of mouthwash can permanently address. If you or those around you notice consistent bad breath, gum health should be the first thing your dentist evaluates.

3. Receding Gums

If your teeth appear to be getting longer — or if you can see or feel more of the tooth surface near the gumline than you used to — your gums may be receding. Gum recession exposes the softer root surface of the tooth, which is more vulnerable to decay and sensitivity. It is also a sign that the gum tissue is being destroyed by infection or — in some cases — by overly aggressive brushing technique. Either cause warrants professional assessment.

4. Swollen, Red, or Tender Gums

Healthy gums are firm, pale pink, and fit snugly against the teeth. Gums that are consistently puffy, dark red, or tender to touch — even without obvious bleeding — are inflamed. Inflammation is the body's immune response to bacterial infection. The swelling itself indicates active disease that should not be left untreated.

5. Teeth That Feel Loose or Are Shifting

If a tooth feels slightly mobile when you press it with your tongue or finger — or if you notice gaps appearing between teeth that were not there before — this is a sign of significant bone loss around the roots. Bone loss is a hallmark of periodontitis and represents an advanced stage of the disease. A dentist should assess this as a priority.

6. Tooth Sensitivity to Temperature

When gum recession exposes the root surface of the tooth, sensitivity to cold water, cold air, or hot beverages becomes common. While sensitivity has other causes, new or worsening temperature sensitivity — particularly concentrated around the gumline — should prompt a gum health assessment alongside any investigation of the tooth itself.

7. Gum Pockets Deeper Than 3mm

This sign is invisible to you at home but is something your dentist assesses at every routine visit using a small, thin instrument called a periodontal probe. In a healthy mouth, the sulcus (the space between the tooth and surrounding gum tissue) measures between 1 and 3 millimetres. Readings of 4mm or more indicate the early formation of periodontal pockets — areas where bacteria are accumulating below the gumline in a space that home care cannot reach. Readings of 5mm and above typically indicate established periodontitis requiring active treatment.

This is one of the most important reasons not to skip routine dental appointments. Your dentist is measuring things you cannot feel or see — and catching pockets at 4mm is far better than discovering them at 7mm.

Do I Need a Periodontist or a Dentist?

This is the most common question patients ask once gum disease has been identified — and the answer depends on the stage and severity of the disease.

See your general dentist first for:

• Gingivitis (early-stage gum disease with no bone loss)

• Mild bleeding gums or early recession without pocket depths exceeding 4mm

• Routine scaling and cleaning above and below the gumline

• Monitoring and maintenance once periodontitis has been treated by a specialist

• Any first assessment of gum symptoms — your dentist will measure pocket depths and determine whether a referral is necessary

You may need a periodontist if:

• Pocket depths consistently measure 5mm or more despite professional cleaning

• X-rays show significant bone loss around one or more teeth

• You have moderate to severe periodontitis that has not responded adequately to non-surgical treatment

• You require surgical procedures such as flap surgery, pocket reduction, guided tissue regeneration, or gum grafting

• You need dental implants in a jaw that has experienced significant bone loss

• Your gum disease is complicated by a systemic condition such as diabetes, an autoimmune disorder, or medications that affect gum tissue

• Your general dentist recommends a specialist referral — always follow this advice

It is important to understand that seeing a periodontist does not mean leaving your family dentist. Periodontal treatment and general dentistry work alongside each other. A periodontist manages the specialist-level intervention; your family dentist at Hwy7 Family Dentistry continues managing your overall dental care, monitoring gum health, and providing maintenance cleanings on the schedule your periodontist recommends — typically every three to four months rather than the standard six months following active periodontal treatment.

Why Gum Health Affects Your Whole Body

The connection between periodontal disease and systemic health is one of the most significant findings in modern dental research — and one that most patients in Markham are not fully aware of.

Research has consistently established associations between untreated gum disease and:

Heart disease: People with periodontitis have a significantly elevated risk of cardiovascular disease. The inflammatory bacteria present in gum infections can enter the bloodstream and contribute to arterial inflammation and the formation of arterial plaques.

Diabetes: The relationship between gum disease and diabetes is bidirectional. Uncontrolled diabetes increases the severity of gum disease; and conversely, untreated periodontitis makes blood sugar levels harder to control. Diabetic patients in Markham should inform their dentist of their diagnosis and ensure gum health is monitored with particular care.

Pregnancy complications: Research has established a link between severe periodontal disease and preterm birth and low birth weight. The Ontario Dental Association recommends that pregnant patients maintain regular dental check-ups throughout pregnancy, with gum health monitoring a priority. Routine cleanings are safe throughout pregnancy.

Respiratory conditions: Bacteria from infected gum pockets can be inhaled into the lungs, contributing to respiratory infections — a concern particularly for older patients or those with existing respiratory conditions.

This systemic connection is why gum health is not simply a cosmetic or comfort concern. It is a genuine contributor to your long-term overall health.

What Does Periodontal Treatment Involve?

Treatment depends entirely on the stage and severity of the disease.

Non-surgical treatment — scaling and root planing (deep cleaning) The first-line treatment for periodontitis is a procedure called scaling and root planing — sometimes referred to as a deep cleaning. Unlike a standard hygiene cleaning, this procedure extends below the gumline to remove tartar deposits from the root surfaces of the teeth and to smooth the root surface (root planing), which removes bacterial toxins and makes it harder for bacteria to re-attach. It is typically performed under local anaesthetic for comfort and is carried out over two or more appointments covering different sections of the mouth. For most patients with early to moderate periodontitis, scaling and root planing produces significant improvement in pocket depths and gum health.

Antibiotic therapy In some cases, your dentist or periodontist may place a localised antibiotic directly into the gum pocket following deep cleaning to address persistent bacterial infection. Systemic antibiotics may be prescribed in cases of acute infection.

Surgical treatment When non-surgical treatment does not achieve adequate reduction in pocket depths, surgical intervention may be required. Common periodontal surgical procedures include:

• Flap surgery (pocket reduction surgery): The gum tissue is temporarily folded back to allow direct access for thorough cleaning of the root surfaces and removal of diseased tissue, then sutured back into place snugly around the tooth.

• Gum grafting: When significant recession has exposed root surfaces, soft tissue taken from the palate (or processed donor tissue) is grafted onto the affected area to restore the gumline and protect the root.

• Bone grafting and guided tissue regeneration: When bone loss has occurred, grafting material can be placed to stimulate bone regrowth, and a membrane barrier is used to direct the regrowth of bone rather than gum tissue.

Periodontal maintenance Following active treatment — whether surgical or non-surgical — periodic maintenance appointments every three to four months are essential. This is not the same as a routine cleaning. Periodontal maintenance involves re-probing pocket depths, monitoring bone levels, and thoroughly cleaning areas that are at ongoing risk. Dropping back to six-monthly appointments too soon after periodontal treatment significantly increases the risk of disease recurrence.

Gum Disease, Risk Factors and Prevention

Certain factors increase your risk of developing gum disease and warrant extra vigilance:

• Smoking or tobacco use — one of the strongest risk factors; tobacco impairs the immune response and masks early bleeding symptoms

• Diabetes — both increases susceptibility and severity of gum disease

• Hormonal changes — pregnancy, menopause, and puberty all alter gum tissue sensitivity

• Certain medications — some blood pressure medications, antidepressants, and antihistamines reduce saliva flow, increasing infection risk; some anticonvulsants and immunosuppressants cause gum tissue overgrowth

• Family history — genetic susceptibility to gum disease is well documented

• Stress — impairs immune function and increases the body's inflammatory response

• Poor nutrition — a diet low in vitamin C and antioxidants reduces gum tissue resilience

Prevention remains the most effective treatment. Brush twice daily with a fluoride toothpaste using gentle circular technique, floss or use interdental brushes daily, avoid tobacco entirely, attend routine dental check-ups every six months (or every three to four months if you have a history of gum disease), and disclose any systemic health conditions or medications to your dentist so gum monitoring can be appropriately scaled.

Frequently Asked Questions

What does a periodontist do? 

A periodontist is a dental specialist with two to three years of additional postgraduate training in the prevention, diagnosis, and treatment of gum disease and the placement of dental implants. They handle cases that require specialist-level care beyond routine dentistry — including deep cleaning under anaesthetic, surgical pocket reduction, gum grafting, bone grafting, and complex implant placement.

Do I need a periodontist or a dentist for gum disease? 

For early-stage gum disease (gingivitis) or mild periodontitis, your general dentist and dental hygienist can provide effective treatment through professional cleaning and scaling. A periodontist is needed when periodontitis is moderate to severe, when pocket depths exceed 4–5mm despite professional cleaning, when significant bone loss is present, or when surgical intervention is required. Your family dentist will advise you when a referral is appropriate.

Is gum disease reversible? 

Gingivitis — the earliest stage — is fully reversible with professional cleaning and consistent home care. Periodontitis, once it involves bone and connective tissue loss, is not fully reversible — but it can be effectively managed and controlled with appropriate treatment, stopping further progression.

What are the early signs of gum disease? 

The most common early signs are bleeding gums during brushing or flossing, persistent bad breath that doesn't resolve with brushing, red or swollen gum tissue, and gums that appear to be receding. In the earliest stages, gum disease is often painless — which is why routine dental assessments with pocket depth measurement are so important.

Can gum disease affect my overall health?  Yes — research has established strong associations between untreated gum disease and an elevated risk of heart disease, difficulty managing blood sugar levels in diabetic patients, pregnancy complications including preterm birth, and respiratory conditions. Treating gum disease is not just about your mouth — it is a meaningful contributor to overall health.

How is gum disease treated?  Treatment depends on severity. Early-stage disease is treated with professional cleaning and improved home care. Established periodontitis is treated with scaling and root planing (deep cleaning below the gumline under local anaesthetic). Advanced cases may require surgical intervention including flap surgery, gum grafting, or bone grafting. Following treatment, periodontal maintenance appointments every three to four months are essential to prevent recurrence.

How much does periodontal treatment cost in Ontario?  Costs vary significantly depending on the extent of treatment required. Basic scaling and root planing is covered in part by most extended health insurance plans. The Canadian Dental Care Plan (CDCP) covers eligible patients for some periodontal services. Ask about your coverage options when you call — our team at Hwy7 Family Dentistry can walk you through what to expect.
