Have you noticed a little blood on your toothbrush recently? Or maybe your gums look puffier than usual, or you've been putting up with persistent bad breath you just can't shake? These are not things to brush off (pun intended); they could be the early signs of gingivitis, the most common and earliest form of gum disease.
The good news? Gingivitis is completely reversible when caught early. The not-so-good news? Most people in New Zealand don't realise they have it until it progresses into something more serious. In fact, 1 in 3 adults in New Zealand have some form of gum disease, and many don't know it.
At Auckland Family Dental, we see patients every week across our Milford, Parnell, Drury, New Lynn, and Southern Care Dental clinics who come in for a routine clean, and we spot gingivitis they had no idea was there. This guide will help you know exactly what to look for, what causes it, and when to book an appointment with a dentist in Auckland.
Key Fact : Gingivitis is reversible with professional treatment. Left untreated, it progresses into periodontitis, a serious form of gum disease that can cause permanent bone loss and tooth loss.
What Is Gingivitis? Understanding the Basics
Gingivitis is inflammation of the gums (gingiva) caused by a build-up of plaque, the soft, sticky film of bacteria that forms on your teeth and gumline every day. When plaque is not removed through regular brushing, flossing, and professional cleans, the bacteria in it irritate the gum tissue, causing it to become red, swollen, and prone to bleeding.
Gingivitis sits at the very start of the gum disease spectrum:
Healthy gums: Pink, firm, no bleeding
Gingivitis: Inflamed, red/purple gums that bleed when brushed. Reversible.
Periodontitis (mild to severe): Gum recession, bone loss, loose teeth requires specialist treatment
Because gingivitis is painless in its early stages, it is effortless to miss, which is exactly why knowing the warning signs is so important.
How to Spot Gingivitis: 8 Warning Signs to Watch For
Here are the most common signs that your gums may be affected by gingivitis. You can check many of these at home with just a mirror and good lighting:
1. Gums That Bleed When You Brush or Floss
This is the most common and recognisable sign of gingivitis. Healthy gums should NOT bleed during normal brushing or flossing. If you notice pink or red on your toothbrush, in the sink, or on floss, your gums are inflamed.
Many people assume bleeding gums are caused by brushing too hard, but in most cases, it is a sign of bacterial infection in the gum tissue. Don't stop brushing or flossing; that will make it worse. Do book a dental hygiene appointment.
2. Red or Purple-Coloured Gums
Healthy gum tissue is a consistent coral pink color. Gingivitis causes the gums to turn red, dark pink, or even purplish due to increased blood flow and inflammation. Check the gum line along your front teeth in a mirror; any color change is worth investigating.
3. Swollen or Puffy Gums
Inflamed gums often appear visibly swollen or 'puffed up' around the bases of the teeth. You may notice the gum line looks thicker than usual or that your gums feel tender to touch even without visible redness.
4. Persistent Bad Breath (Halitosis)
Chronic bad breath that doesn't improve with brushing, mouthwash, or mints can be a sign of gingivitis. The bacteria responsible for gum disease release sulphur compounds, creating a distinct unpleasant odor that originates from deep in the gumline, not just the surface of the teeth or tongue.
5. Gums That Have Pulled Away from the Teeth
Look closely at where your gum meets your tooth. If there appears to be a gap, or the tooth looks longer than it used to, your gums may be receding, a sign that gingivitis is progressing or has already advanced toward periodontitis.
6. Tender or Sensitive Gums
While early gingivitis is often painless, gum tenderness is a common symptom as it progresses. If your gums hurt when eating crunchy foods or feel sore to the touch along the gumline, don't ignore it.
7. Gums That Look Shiny or Appear to Have a Different Texture
Healthy gum tissue has a slightly dimpled, matte appearance (like orange peel). Inflamed gums may look shiny or smooth due to swelling. This is a subtle visual cue that is often overlooked but is a reliable indicator of early gum disease.
8. A Change in the Way Your Teeth Fit Together
If your bite feels different or if teeth that never used to touch are now making contact, this can be an indirect sign that your gum tissue or supporting bone is changing. This symptom is more commonly associated with advancing gum disease but is worth mentioning to your dentist.
How to Tell If You Have Gingivitis at Home
You can do a basic self-check at home in under 2 minutes. Here's what to do:
Stand in front of a mirror in good lighting.
Gently pull your lip back to expose the gumline of your upper and lower front teeth.
Look for any redness, swelling, or color changes in the gum tissue.
Brush your teeth normally and check your toothbrush and the sink afterwards for blood.
Floss between two teeth and check whether the floss is pink or red when removed.
Notice whether you have any sensitivity, bad taste, or persistent bad breath.
If you notice two or more of the signs above, there is a strong likelihood you have gingivitis, and it is time to book a professional dental hygiene check-up. At-home checks are helpful, but only a dentist or hygienist can properly examine your gum pockets, measure recession, and confirm a diagnosis.
Remember: gingivitis is painless in early stages, so the absence of pain is NOT a reliable sign that your gums are healthy.
What Causes Gingivitis? Common Risk Factors in New Zealand
Plaque is the primary cause of gingivitis, but several factors can make you more vulnerable:
Poor oral hygiene: Not brushing twice daily, skipping flossing, or using incorrect technique allows plaque to harden into tartar, which can only be removed by a dental professional.
Irregular dental check-ups: Without a professional scale and clean every 6 months, tartar accumulates below the gumline where no toothbrush or floss can reach.
Smoking or vaping: Tobacco products reduce blood flow to the gums, masking inflammation and making gum disease harder to detect AND harder to treat.
Hormonal changes: Pregnancy, puberty, and menopause all cause hormonal fluctuations that make gum tissue more sensitive and reactive to plaque. Pregnancy gingivitis is very common in New Zealand.
Diabetes: People with poorly controlled diabetes are significantly more likely to develop gum disease, and gum disease in turn can make blood sugar harder to control, a two-way relationship.
Certain medications: Some blood pressure medications, anticonvulsants, and immunosuppressants can cause gum overgrowth or dry mouth, increasing gingivitis risk.
Dry mouth (xerostomia): Saliva is a natural defender against bacteria. Less saliva means more bacterial growth and a higher risk of gum inflammation.
Stress: Chronic stress weakens the immune system, making it harder for your body to fight off gum infections.
Nutritional deficiencies: A lack of vitamin C in particular has been linked to gum inflammation. A diet high in sugar also feeds the bacteria responsible for gingivitis.
How Is Gingivitis Treated? What to Expect at Auckland Family Dental
The wonderful news about gingivitis is that with the right professional treatment and improved home care, it can be completely reversed. Here's what treatment looks like:
Professional Scale and Clean
Our dental hygienists perform a thorough scale and clean (also called a prophylaxis) to remove all plaque and tartar from above and below the gumline. This is the single most effective treatment for gingivitis and cannot be replicated at home. Most patients notice their gums look and feel healthier within a few days of a professional clean.
Ultrasonic Cleaning
For stubborn tartar build-up, we use ultrasonic scalers that use high-frequency vibrations to break down deposits gently and effectively, particularly useful for patients with sensitive teeth or gum pockets.
Personalised Home Care Plan
Our hygienists won't just clean your teeth and send you on your way. We'll show you the correct brushing technique, advise on the best flossing tools for your teeth, and recommend specific products (such as a chlorhexidine mouthwash or an electric toothbrush) if needed.
Follow-Up Appointments
For more established gingivitis, we may recommend follow-up hygiene appointments every 3–4 months initially to monitor healing and ensure the gums are responding to treatment.
How to Prevent Gingivitis: Your Daily Gum Health Checklist
Prevention is always better than treatment. Follow this daily checklist to keep your gums healthy between dental visits:
Brush your teeth twice daily for a minimum of 2 minutes using a soft-bristled toothbrush
Use fluoride toothpaste; it strengthens enamel AND helps reduce bacterial load
Floss or use interdental brushes once a day; plaque between teeth causes up to 35% of gum disease
Use an antibacterial or fluoride mouthwash as an additional layer of protection
Stay well-hydrated; dry mouth increases bacterial growth significantly
Limit sugary and acidic foods and drinks, which feed the bacteria that cause plaque
Quit smoking. Smokers are up to 7x more likely to develop gum disease
Book a professional dental hygiene appointment every 6 months at Auckland Family Dental
Tell your dentist about any medications, health changes, or hormonal shifts (e.g., pregnancy)

Frequently Asked Questions - Gingivitis & Gum Disease in Auckland
How do I know if I have gingivitis or something more serious?
Gingivitis causes red, swollen gums that bleed easily but don't involve bone or tooth loss. If you are also experiencing gum recession, loose teeth, deep gum pockets, or persistent pain, it may have progressed to periodontitis. A professional examination at Auckland Family Dental is the only way to get an accurate diagnosis.
Can gingivitis go away on its own without treatment?
Gingivitis will not resolve itself without intervention. While improved brushing and flossing can slow its progression, the tartar that causes the majority of gum inflammation can only be removed by a dental professional. Without treatment, gingivitis consistently progresses to more serious gum disease over time.
Is gingivitis contagious?
The bacteria that cause gingivitis can be passed between people through saliva, for example, through kissing or sharing utensils. However, developing gingivitis depends heavily on your own oral hygiene habits and immune health. It is not considered 'contagious' in the traditional sense, but shared bacteria can increase risk.
How long does it take to reverse gingivitis?
With a professional scale and clean combined with an improved home care routine, most patients see significant improvement in gum health within 2 to 4 weeks. More established gingivitis may require 2 to 3 professional hygiene appointments spaced over a few months.
Why do my gums bleed when I floss - should I stop flossing?
No. Stopping flossing will make things worse, not better. Bleeding gums when flossing is a sign of gum inflammation caused by plaque build-up between the teeth. Regular gentle flossing removes this plaque and, combined with a professional clean, should stop the bleeding within 1 to 2 weeks.
Can children get gingivitis?
Yes. Gingivitis can affect people of all ages, including children and teenagers. Hormonal changes during puberty can make young people especially susceptible. Auckland Family Dental offers dental care for children and teens, including free teen dentistry for eligible patients.
Does gingivitis cause pain?
In its early stages, gingivitis is typically painless, which is why so many people miss it. As inflammation progresses, gums can become tender to touch or sensitive to hot and cold. If you are experiencing noticeable pain, the disease may have advanced beyond gingivitis.
How much does a dental hygiene clean cost in Auckland?
The cost of a professional scale and clean at Auckland Family Dental varies depending on the amount of buildup and the length of the appointment. We recommend calling your nearest clinic for a current price guide. We also offer flexible payment plans to help with the cost of dental care.
