Gum health is one of the most important and most overlooked aspects of dental care. Most people know they should brush and floss, but far fewer understand what healthy gums actually look like, what the warning signs of gum disease are, or what happens if it goes untreated.
What do healthy gums look like?
Healthy gums are firm, pale pink, and fit snugly around each tooth. They do not bleed when you brush or floss, they do not feel tender or swollen, and they sit at a consistent level around the base of each tooth without pulling away. If your gums are red, puffy, or bleed regularly, that is a sign that something is off, even if it does not hurt.
Why do my gums bleed when I brush?
Bleeding gums are the most common early sign of gingivitis, which is the mildest and most reversible form of gum disease. The bleeding happens because the gum tissue is inflamed from bacterial buildup along the gumline. A common misconception is that bleeding means you are brushing too hard and should brush more gently. In most cases, the answer is actually to brush more thoroughly and to floss consistently. The bleeding typically resolves within a couple of weeks once the bacterial load is reduced. If it does not, come and see us.
Is it normal for gums to bleed occasionally?
Occasional bleeding if you have not flossed in a while is common and not necessarily alarming. Regular bleeding, meaning most days when you brush or every time you floss, is not normal and should be looked at. Bleeding gums that are left unaddressed tend to progress rather than resolve on their own.
What is the difference between gingivitis and periodontitis?
Gingivitis is inflammation of the gum tissue caused by bacterial buildup. It is confined to the gums themselves and is fully reversible with professional cleaning and improved home care. Periodontitis is what gingivitis becomes if it is not treated. The infection spreads below the gumline and begins to destroy the bone and connective tissue that hold teeth in place. Unlike gingivitis, the damage caused by periodontitis is not fully reversible, though treatment can stop it from progressing. This is why catching gum disease early matters so much.
Can I have gum disease without knowing it?
Yes, and this is one of the reasons it is so problematic. Gum disease is often painless in its early and middle stages. Patients are frequently surprised to learn they have significant periodontal disease because nothing has hurt. By the time pain develops, the disease is often advanced. Regular professional examinations are the only reliable way to catch gum disease before it becomes serious.
Causes and Risk Factors
What causes gum disease?
Gum disease is caused by bacterial plaque, the sticky film that forms on teeth throughout the day. When plaque is not consistently removed through brushing and flossing, it hardens into tartar, a calcified deposit that cannot be removed at home and that harbours harmful bacteria. Over time those bacteria cause the inflammation and infection that define gum disease. Other factors including smoking, diabetes, hormonal changes, certain medications, and genetics can significantly increase susceptibility.
Does smoking affect gum health?
Significantly. Smoking is one of the strongest risk factors for gum disease. It reduces blood flow to the gums, which masks the bleeding that would otherwise signal a problem, and it impairs the immune response that would normally fight infection. Smokers are far more likely to develop severe periodontal disease and far less likely to respond well to treatment. The masking of symptoms is particularly concerning because it means smokers can have advanced gum disease without the usual warning signs.
Can stress cause gum problems?
Stress does not directly cause gum disease but it creates conditions that make it more likely. Stress impairs immune function, making it harder for the body to fight bacterial infection. It also tends to be associated with poorer oral hygiene habits, increased alcohol consumption, smoking, and teeth grinding, all of which are risk factors for gum problems. Patients going through particularly stressful periods are worth watching more closely.
Do hormonal changes affect gum health?
Yes, quite significantly. Hormonal fluctuations during puberty, menstruation, pregnancy, and menopause all affect how gum tissue responds to bacteria. Pregnancy gingivitis is a well-documented condition where gums become more reactive and inflamed during pregnancy even with normal oral hygiene. Women on hormonal contraceptives can also experience increased gum sensitivity. This does not mean hormonal change causes gum disease, but it does mean the gums need extra attention during these periods.
Can my medication affect my gums?
Several common medications have gum-related side effects. Some antihypertensives, anti-seizure medications, and immunosuppressants can cause gum overgrowth, a condition called gingival hyperplasia where the gum tissue thickens and can partially cover the teeth. Many medications also cause dry mouth, which reduces the protective effect of saliva and increases the risk of both decay and gum disease. Always let us know what medications you are taking so we can factor them into your care.
Is gum disease genetic?
There is a genetic component to gum disease susceptibility. Some people are more prone to aggressive inflammatory responses to bacterial infection, meaning they can develop significant gum disease even with reasonably good oral hygiene. If a parent or sibling has had significant gum disease or tooth loss related to periodontitis, it is worth mentioning to us so we can monitor you more closely. Genetics loads the gun but oral hygiene and lifestyle pull the trigger.
Treatment and Management
How is gum disease treated?
Treatment depends on the stage. Early gum disease (gingivitis) typically responds to a thorough professional cleaning combined with improved home care. More advanced gum disease (periodontitis) requires a deeper cleaning procedure called scaling and root planing, where deposits are removed from below the gumline and the root surfaces are smoothed to make it harder for bacteria to reattach. In some cases, antibiotics or antimicrobial rinses are used alongside mechanical cleaning. Surgical treatment is occasionally needed for the most severe cases. Our gum disease treatment page covers this in more detail.
Does gum disease treatment hurt?
Deep cleaning (scaling and root planing) is performed with local anaesthetic so the procedure itself should not be painful. Some tenderness and sensitivity in the days following treatment is normal as the gum tissue heals. Over-the-counter pain relief is usually sufficient. Most patients are surprised by how manageable the recovery is relative to what they had imagined.
Can gum disease be cured?
Gingivitis is fully reversible and can be considered cured with appropriate treatment and home care. Periodontitis cannot be cured in the sense of restoring destroyed bone and tissue, but it can be controlled. Successfully treated periodontitis means the disease is arrested and no longer progressing. Maintenance appointments every three to four months rather than the standard six are typically recommended for patients with a history of periodontitis, because the bacterial colonies that drive the disease re-establish themselves more quickly in susceptible individuals.
Why do I need more frequent cleanings if I have had gum disease?
Once you have had periodontitis your gums are more vulnerable to recurrence. The pockets that form between teeth and gums during active disease, even after successful treatment, provide hiding places for bacteria that are harder to reach with home brushing and flossing. More frequent professional cleanings keep the bacterial load in those pockets at a level your immune system can manage. Think of it as maintenance for a system that needs more attention than average, not a punishment for past problems.
Can receding gums grow back?
Unfortunately not. Gum tissue that has receded does not regenerate on its own. In cases of significant recession, gum grafting procedures can restore coverage and protect exposed root surfaces. What we can do is stop the recession from progressing by treating the underlying cause, whether that is gum disease, aggressive brushing, or grinding. Catching recession early gives us the most options.
What can I do at home to improve my gum health?
Consistent, thorough brushing twice a day with a soft-bristled brush, daily flossing or interdental cleaning, and rinsing with an antibacterial mouthwash where appropriate are the foundations. Technique matters as much as frequency. A soft-bristled brush used gently at a 45-degree angle to the gumline is more effective and less damaging than a hard brush used with force. Electric toothbrushes consistently outperform manual brushing in clinical studies and are worth considering if you struggle with technique. And do not skip flossing. Brushing alone misses roughly 40% of each tooth surface.
Gum Health and the Rest of Your Body
Can gum disease affect my heart?
Research consistently shows a link between periodontal disease and cardiovascular disease. The bacteria associated with gum disease can enter the bloodstream through inflamed gum tissue and contribute to arterial inflammation and plaque buildup. People with gum disease have a significantly higher risk of heart attack and stroke than those without. We cover this connection in depth on our oral and systemic health page.
I have diabetes. Does that affect my gums?
Diabetes and gum disease have a two-way relationship. Elevated blood sugar creates conditions where harmful oral bacteria thrive, making diabetic patients more susceptible to gum disease. And active gum disease makes blood sugar harder to control by driving systemic inflammation that interferes with insulin function. Treating gum disease in diabetic patients has been shown to improve blood sugar control. If you have diabetes, regular dental care is an important part of managing your condition, not a separate concern.
Can gum disease affect pregnancy?
Yes. Untreated periodontal disease during pregnancy has been linked to increased risk of preterm birth and low birth weight. Pregnancy also increases susceptibility to gum inflammation due to hormonal changes. Dental care during pregnancy is safe and recommended. We cover this in more detail on our dental care during pregnancy page.
I have been told my bad breath is coming from my gums. Is that possible?
Absolutely. Persistent bad breath (halitosis) that does not resolve with brushing and mouthwash is often a sign of gum disease. The bacteria responsible for periodontal infection produce volatile sulphur compounds as a byproduct of their activity, and these are the primary source of the characteristic odour. Treating the gum disease addresses the source rather than masking the symptom. If bad breath is a persistent concern, a gum health assessment is a sensible starting point.
Practical Questions
How do I know if my gums are receding?
Common signs include teeth that look longer than they used to, increased sensitivity at the gumline, a notch you can feel at the base of a tooth, or a visible colour change where the root surface meets the enamel. Some recession is gradual enough that patients only notice it when it is pointed out during an examination, which is another reason regular check-ups matter.
What toothbrush is best for sensitive or receding gums?
A soft-bristled brush, either manual or electric, is the right choice for most people and especially for those with sensitive or receding gums. Medium and hard bristles cause more gum trauma and enamel wear than most people realise. If you are currently using a medium or hard brush, switching to soft is one of the simplest and most effective changes you can make for your gum health.
Is an electric toothbrush better for gum health?
The evidence suggests yes, on average. Electric toothbrushes, particularly oscillating-rotating types, consistently remove more plaque than manual brushing in clinical studies and cause less gum trauma when used correctly. They are particularly helpful for patients who tend to brush too hard or who struggle with the technique required to clean effectively along the gumline. That said, a manual brush used well beats an electric brush used poorly.
How often should I have my gums checked?
A gum assessment should be part of every routine dental examination. For most patients with healthy gums, this means twice a year. For patients with a history of gum disease, more frequent visits of every three to four months are typically recommended. If you have not had a proper periodontal assessment recently or cannot remember the last time your gum pockets were measured, it is worth scheduling one.
