Gingivitis is a common mild inflammation of your gums. It is caused by the build-up of plaque on your teeth. It can usually be easily treated with brushing twice a day and flossing daily.
- Gingivitis is a common mild inflammation (redness and swelling) of your gums. It is a sign of poor oral hygiene.
- It is caused by the build-up of plaque on your teeth due to not brushing and flossing regularly enough.
- Symptoms include red and tender gums, and bleeding when brushing or flossing.
- You can usually treat gingivitis at home yourself through good oral hygiene, such as brushing your teeth twice a day and flossing them once each day.
- If left untreated, gingivitis may progress into more serious gum diseases, known as periodontitis, although this does not always happen.
What are the causes of gingivitis?
Gingivitis is a sign that there is excess plaque in your mouth, which your body is fighting back against through inflammation. As your gums get inflamed, they can become puffy and bleed when you brush.
This happens because your mouth is full of bacteria. These bacteria, along with mucus and other particles, constantly form a sticky ‘plaque’ on your teeth. If you don’t brush and floss regularly, the plaque can harden and form ‘tartar’ (also known as ‘calculus’). Calculus increases the rate at which plaque forms, as it provides a base for the bacteria. This causes inflammation of your gums, or gingivitis.
What are the symptoms of gingivitis?
It can be easy to overlook mild gingivitis. You may be unaware of it until your dentist or hygienist checks for it. Look out for the following symptoms:
- swollen red gums
- bleeding when brushing, flossing or eating
- tenderness or pain
- bad breath (halitosis)
- sensitivity to cold or hot foods and drinks.
Who is at risk of gingivitis?
Gingivitis can affect anybody but you are at increased risk of you:
- have poor brushing habits, which leads to plaque and tartar building up
- have diabetes (especially if poorly controlled)
- are obese
- have a weakened immune system
- have a dry mouth (saliva is protective) – this can be caused by some medications and aging
- have poorly fitting dentures
- brush your teeth too hard
- are pregnant
- have a diet lacking in vitamins and minerals.
What is the treatment for gingivitis?
In most cases, you can treat gingivitis at home by following good oral hygiene practices. These include:
- brushing your teeth twice a day (first thing in the morning and before bed) with a fluoride toothpaste
- using a soft or ultra-soft toothbrush – medium and hard toothbrushes can damage your gums and can be less effective at removing plaque
- flossing regularly to remove plaque from between your teeth – if you have larger gaps between your teeth a dental professional might recommend you use an interdental brush
- considering using an electric toothbrush rather than a manual one
- using mouthwash daily after brushing to further reduce bacteria in your mouth.
For acute gingivitis, use a mouth rinse such as Colgate Savacol for up to 2 weeks (longer-term use may stain your teeth). If your gingivitis is chronic, use any mouthwash daily. If your gingivitis persists, see a dentist.
You should also:
- visit your dentist routinely for a check-up and professional cleaning
- be smokefree and limit alcohol intake
- avoid cannabis use as this is associated with severe gingivitis and periodontitis
- avoid eating sugary foods between meals.
Can gingivitis progress to more serious conditions?
If left untreated, gingivitis may progress to more deep-seated inflammation and infections in the mouth, such as periodontitis (periodontal or gum disease), although this doesn’t always happen. Periodontal or gum disease can destroy the ligaments and bone holding your teeth securely in place so that they become loose and teeth may eventually fall out.
Gingivitis can also lead to acute necrotising ulcerative gingivitis, which is a condition that causes pain, tissue loss and foul breath.
How can I prevent gingivitis?
Prevention is the same as treatment. If you follow the steps outlined under treatment, you have much less risk of developing gingivitis.
Avoiding smoking is a key step in keeping your gums healthy. People who smoke have a higher risk of gum problems (and oral cancer), such as complications after tooth extractions and surgery in your mouth. You have lower resistance to infections and your healing is impaired.
Gum conditions in smokers are also often not noticed as smokers typically do not have bleeding gums as they have poor blood supply to the gums. If you are a smoker and you stop smoking, your gums are likely to start to bleed. This is because the blood supply is returning to your gums and they are starting to fight the plaque.
