Gingivitis is a common but mild form of gum disease, the first sign of which is often bleeding gums. Left untreated, it can progress to a more serious condition called periodontitis – this may result in loss of teeth and the bone supporting them.
Alarmingly, data from the WHO (World Health Organization) shows more than 75% of people aged between 35 and 45 and more than half of adolescents over the age of 15 are affected by some kind of gingival problem.
Gingivitis develops when dental plaque (a film of bacteria on the teeth) isn't cleaned away properly. Good oral hygiene will help stop it from recurring.
In this article you can read all about the different types of gum disease, what the symptoms are, and the best way to keep your mouth and gums healthy.

What is gingivitis?
Gingivitis is a form of gum disease accompanied by gum tenderness and bleeding. Fortunately, if caught in the early stages, gingivitis cures are very effective. 1 in 2 American adults over 30 years of age has gum disease.
For a brief overview of the condition you can view this short video:
There are three main stages of periodontal (gum) disease. Each displays different symptoms and requires a different type of treatment.
Gingivitis is the most mild form, where the gums are inflamed rather than infected. Catching it at this stage will help prevent irreversible oral damage.
The table below summarises the different phases of gum disease. Keep reading to find out more about causes, symptoms, treatment and prevention.
Red, swollen or bleeding gums; bad breath
Tartar (calculus) build-up; receding gums; loose teeth
Loose teeth; pain while eating
Mild inflammation of gum tissue
Infection of gum tissue
Severe infection of tissue and bone
Effects on oral health
No long-term effects if treated early
Irreversible damage to bone and tissue
Destruction of bone and tissue; possible tooth loss or misalignment
Scale and polish with a dental hygienist; better oral hygiene
Scaling, root planing or dental surgery to remove infection
Dental surgery, possibly bone grafts and tooth extraction
Good oral care and regular dental checkups
Maintain good oral hygiene and check for gingivitis symptoms regularly
Visit a dentist if you think you may have periodontal disease
What causes gum disease?
Bacteria are constantly present in our mouths from saliva. If you don't clean your teeth properly, bacteria get into the space between the teeth and gums causing inflammation and swelling. Pockets sometimes form in the gums, allowing food to lodge and more plaque to build up.
Bacteria feed on food left in our mouths after we eat. These bacteria form a sticky, colorless film on our teeth and gums called dental plaque. Have you ever tried to clean ‘furry' teeth with a fingernail? The substance you scraped off was plaque.
Plaque hardens over time, forming a hard yellowish-white residue called ‘tartar' or ‘calculus'. This hard calcareous layer acts as a further breeding ground for bacteria to attack gum tissue.
As periodontal disease becomes more advanced, teeth may become loose and eventually fall out. Dental probiotics can aid in helping good bacteria thrive in your mouth to stave off gum disease.
Although plaque is the main culprit, certain people are more susceptible to gum disease than others. Those particularly at risk include:
- Teenage girls and menopausal women: Hormonal changes make gums more sensitive and prone to disease. This can affect all women as they go through their monthly menstrual cycle, but hormones are particularly active during puberty and menopause.
- Postmenopausal women: A painful condition called desquamative gingivitis can affect postmenopausal women. The outer layer of the gum detaches from the teeth, leaving them loose and crooked. Nerve endings can then be exposed and cause extreme pain. Dental insurance can help lower the cost of any periodontal treatment you might need later in life. Read about the best dental insurance plans in the US.
- Pregnant women: A nine-month dose of hormones during pregnancy means many expectant mothers notice their gums bleeding. In addition, hormonal variations may lead to localized hypertrophic gingivitis (also known as pregnancy gingivitis). This can be identified by a bright red (benign) pseudo-tumor at the base of one or more teeth that can bleed profusely.
- People with diabetes: Studies have shown a vicious cycle here, with diabetes making periodontal disease worse, and vice versa.
- Smokers: Smoking is responsible for as many as 50% of gum disease cases, mainly because it increases plaque levels.
- People with vitamin deficiencies: Specifically vitamin C and vitamin B3 (niacin).
- People under severe stress: Acute necrotizing ulcerative gingivitis (ANUG) is identifiable by acutely painful, bleeding gums. It often occurs suddenly and as a result of severe stress or a significant traumatic event. Learn more about the connection between mental health and oral health.
There are other factors which may contribute to gum problems, including:
- Tooth fillings
- Poorly-fitting dental restorations including crowns and bridges
- Crooked teeth (which are harder to clean properly)
- Poor oral hygiene while wearing braces
- Certain medications, including birth control pills
If you are in any of these high-risk groups, particularly if you're pregnant or going through menopause, be sure to get regular dental checkups so your dentist can deal with any problems quickly.
Is gingivitis contagious?
It is generally understood that most people affected by gum disease have an underlying medical disease or are experiencing hormonal changes that make them more susceptible to bacteria.
But at the same time, these oral bacteria are spread through saliva. Technically, then, gingivitis can be spread by kissing or by sharing utensils and dental equipment. However, if you have healthy gums and maintain good oral health, you shouldn't be at risk of developing any kind of periodontal disease from contact with someone else.
Mild gingivitis is most commonly manifested by the following symptoms:
- Red, swollen gums
- Gummy smile (read more here)
- Purple-red patches at the gum line
- Receding gums
- Gums bleeding (especially during brushing, flossing or eating)
- Constant bad breath (halitosis)
- A bad taste in the mouth
- Teeth sensitive to hot and cold
Periodontal disease is generally completely painless up to a fairly advanced stage – unlike most dental problems. This, coupled with the fact that there may be no visible symptoms, can make it difficult to diagnose.
Because you probably won't experience any pain as a warning sign of gum problems, it's important to be familiar with and regularly check for the symptoms. Otherwise it could develop to advanced periodontitis before you realize something is wrong.
In the later stages of periodontal disease, or with specific types of gingivitis, other more worrying symptoms may develop. These include:
- A loose tooth or teeth
- Teeth shifting position (you may notice they feel different when you bite down)
- Pus oozing from the space between teeth and gums (an indication of infection or tooth abscess)
- Bright red gums
- Dozens of grey or yellow mouth ulcers appearing on the gums or insides of cheeks
What to do if you have painful or bleeding gums
Don't be tempted to assume that your gums are bleeding because you brushed a little too hard. Easing off on your brushing may solve the bleeding, but it will just aggravate the underlying cause of gingivitis, if that is what you have.
It's better to be safe than sorry, so book an appointment with your dentist and mention your bleeding gums.
Your dentist will use a small measuring device to check whether your gums have started to separate from your teeth. They will also look for any other indications as to the extent of the problem. If the infection has progressed, they may take dental x-rays to check for bone deterioration.
If you have painful or bleeding gums, or any other symptoms of gum disease, don't hesitate to see your dentist. The earlier they remove the source of the inflammation or infection, the less chance of it causing lasting damage. Read more about bleeding gums in our complete article here.
How to prevent periodontal disease
The key to preventing gum disease is simply maintaining good oral hygiene. This involves:
- Brushing teeth twice a day for at least two minutes using a fluoride toothpaste
- Flossing at least once a day
- Rinsing with antibacterial fluoride mouthwash
- Using a dental water jet to clean hard-to-reach places (especially if you are prone to gingivitis)
- Changing your toothbrush regularly
- Being extra careful with cleaning if you wear braces
- Not smoking
- Visiting your dentist and dental hygienist regularly, as advised
If you're unsure how to brush your teeth or floss properly, check out our guide on how to brush your teeth which has detailed instructions. Also, don't be embarrassed about asking your dentist or dental hygienist to show you. Dental professionals want to help you keep your teeth in the best condition possible, so it's better to ask for help than to just assume you're doing it right.
Your dentist can also advise you on the best type of toothbrush and toothpaste to use.

How to treat gingivitis
If you are already displaying some gingivitis symptoms or are worried you may have an oral infection, speak to your dentist. Although improved dental hygiene can be enough to reverse gingivitis in its early stages, it's best to get a professional opinion.
Your dentist may just give your teeth a good clean and send you away with some advice for better dental care. They may also provide you with special mouthwash or cleaning tools to prevent future bacterial growth.
In more severe cases, your dentist will conduct a tooth scaling. This is a thorough cleaning and removal of plaque and tartar from above and below the gum line. This treatment may be repeated every three to six months if you are particularly susceptible to plaque build-up.
If you have developed periodontitis, your dentist may need to perform a procedure called root planing as part of a deep cleaning or refer you to a periodontist who specializes in these gum procedures. This involves smoothing out the rough spots on the tooth root so there is less of a surface for plaque to cling to in future.
In advanced cases of gum disease, flap surgery may be necessary. A specialist called a periodontist makes an incision in the gums to access the infected parts of the gum. The infected area is thoroughly cleaned, then the flaps are stitched up so the gums can heal. Read more about how to fix receding gums in our full article. Laser gum surgery, also called LANAP gum surgery, is a low-impact alternative to traditional gum surgery.
The most chronic cases may require a bone graft to restore damaged bone. This is particularly important if a patient plans to have dental implants to replace lost teeth.
Don't be put off by thinking you might have to have surgery though; these procedures can be avoided by following a good oral hygiene program and seeking treatment as soon as symptoms appear.
Scaling and root planing are dental services intended to provide a healthy tissue environment that will allow tissues to re-adapt to normal tooth surfaces. Periodontal disease, also known as gum disease, is caused by a buildup of plaque, calculus, and stain on the crowns and root surfaces of the teeth.
While it can begin as localized gum inflammation, it can quickly progress to serious disease that can cause major damage to the soft tissue and bone supporting the teeth. Scaling and root planing can help treat the disease before it causes the tooth to fall out or have to be extracted.

Gingivitis treatment at home
You may be able to combat mild gum problems at home by just improving your dental health routine as discussed above. However, without visiting a dentist you can't be sure how far the infection has spread.
If you have tartar build-up below the gum line, for example, bacteria will continue to eat away at your gum tissue and bone. No amount of careful brushing can fix this, so it's best to get a checkup with a professional if you think you may have gingivitis.
Tartar can only be removed with dental scaling. If you can see a white deposit at the base of your teeth, don't try to remove it at home. Instead, visit a dental hygienist for professional scaling.
Is gingivitis treatment covered by Medicare or Medicaid?
Treatments for gingivitis and gum disease are generally not covered by Medicare. Medicaid coverage for low-income individuals is going to vary depending on which state you live in.
The cost of a basic consultation – including diagnosis, advice, and a scale and polish if necessary – can vary, ranging anywhere from $50 to upwards of $200. The costs of any other treatment relating to periodontitis can add hundreds of dollars.
