Gingivitis and Periodontitis: Differences, Symptoms, and Prevention

Gingivitis and periodontitis are among the most common and underestimated oral diseases .
They begin with inflamed, swollen or bleeding gums , but if left untreated they can compromise the tissues supporting the teeth and, in the most severe cases, lead to tooth loss .
Recognizing its early symptoms is essential to intervene promptly and prevent complications.

What is gingivitis?

Gingivitis is a superficial inflammation of the gums , often due to the accumulation of bacterial plaque or tartar .
It is a reversible condition , but represents the first stage of periodontal disease: if neglected, it can evolve into periodontitis , a more serious and irreversible form of infection.

From a microbiological point of view, gingivitis arises from the accumulation of bacterial biofilm , a set of microorganisms that adhere to the surface of the teeth forming a sticky and resistant film.
When plaque is not removed with daily brushing, the minerals in saliva calcify it, turning it into tartar and promoting gum inflammation.

Symptoms of gingivitis

Healthy gums are firm , pink in color, and do not bleed when brushing.
Gingivitis, on the other hand, manifests itself with a series of typical symptoms:

• Swollen, red and sensitive gums .
  

• Bleeding gums , especially when brushing or flossing.
  

• Persistent bad breath (halitosis) .
  

• Pain or discomfort when eating hard or hot foods.
  

• Receding gums , exposing the root of the tooth.
  

• Strange taste in the mouth or a “pulsing” sensation at the gum edges.
  
  

Early signs: If you notice traces of blood while brushing your teeth or your gums feel sore, it's time to see your dentist.
Gingivitis is often painless, but that doesn't mean it isn't progressing.

Causes and risk factors

The main cause of gingivitis is bacterial plaque which accumulates along the gum line. However, several factors can promote its development or worsen its symptoms:

• Poor oral hygiene or incorrect use of the toothbrush.
  

• Smoking and excessive alcohol consumption.
  

• Diet rich in sugars or poor in vitamins (especially vitamin C).
  

• Hormonal changes , such as pregnancy, puberty, or menopause.
  

• Systemic diseases (diabetes, autoimmune diseases, Crohn's disease).
  

• Prolonged use of certain drugs (antiepileptics, cortisone, antidepressants).
  

• Chronic stress , which weakens the immune system.
  

• Dentures or orthodontic appliances that make cleaning more difficult.
  

Gingivitis is also common in children and adolescents , especially in the presence of fixed braces and irregular hygiene routines.

From gingivitis to periodontitis

If gingivitis is left untreated, the inflammation can spread to the deeper tissues of the periodontium—the gums, bone, and ligaments that support the tooth.
This stage is called periodontitis (or pyorrhea ), an irreversible condition that requires specific professional treatments.

Difference between gingivitis and periodontitis

Periodontitis is characterized by the formation of periodontal pockets , spaces that open between the gums and the teeth where plaque and bacteria accumulate.
Over time, these pockets deepen and cause bone loss and loose teeth .

How to treat gingivitis

The good news is that gingivitis is reversible if treated promptly.

Professional treatment

The first step is a dental examination to assess the extent of the inflammation.
The specialist performs a professional scaling or, in more advanced cases, a gingival curettage , to remove plaque and tartar above and below the gum line.

Home treatment

After cleaning, it is essential to maintain daily oral hygiene:

• Brush your teeth after every meal, using soft bristles.
  

• Use dental floss or interdental brushes.
  

• Clean your tongue to reduce bacterial load.
  

• Rinse with a chlorhexidine-based antiseptic mouthwash (only if recommended by your dentist).
  

If you experience severe pain or inflammation , your dentist may recommend an anti-inflammatory gum medication or a medicated mouthwash.

Natural remedies

Some natural ingredients can temporarily relieve symptoms:

• Aloe vera, sage and calendula , with soothing and antibacterial effects.

• Salt water (1 teaspoon in a glass of warm water) as a mild disinfectant.
  

Warning: Home remedies are never a substitute for professional cleaning or dental advice.

Prevention and daily oral hygiene

Prevention is the key to avoiding gingivitis and stopping the progression to periodontitis.

Ideal routine for healthy gums

1. Brush 2–3 times a day for at least two minutes, using an electric toothbrush and fluoride toothpaste.
   

2. Floss daily.
   

3. Apply an antibacterial mouthwash (alcohol-free).
   

4. Have professional scaling done every 6 months.
   

5. Quit smoking and limit sugar and alcohol.
   

6. Follow a balanced diet , rich in vitamin C, calcium and omega-3.
   

7. Managing stress and getting regular sleep also helps your immune system.
   

How to strengthen your gums

Gently massaging your gums with a soft toothbrush and improving local circulation helps keep them strong.
A diet rich in crunchy vegetables and citrus fruits contributes to healthy gum tissue.

What happens if you don't treat gingivitis?

If left untreated, gingivitis can turn into periodontitis , with progressive loss of supporting tissues.
In advanced cases, the bacteria can reach the bloodstream and contribute to systemic conditions such as:

• Cardiovascular diseases (chronic inflammation and atherosclerosis).
  

• Hyperglycemia in diabetic patients.

• Premature birth in pregnant women.
  

Did you know?

Taking care of your gum health not only protects your smile, but also your heart and immune system.
International studies (NCBI, 2024) show that treating gingivitis reduces systemic inflammatory markers.

When to see a dentist

It is advisable to book a dental visit if you notice:

• Frequent bleeding gums.
  

• Persistent pain or swelling.
  

• Gum abscess or pus between the gum and tooth.
  

• Receding gums or teeth that appear longer.
  

• Bad breath that doesn't go away despite daily cleaning.
  

Early screening allows us to stop the disease before it becomes irreversible.

Frequently Asked Questions

What is the difference between gingivitis and periodontitis?
Gingivitis is a superficial, reversible inflammation of the gums; periodontitis is a deep infection involving the bone and dental ligaments.

Is salt water good for inflamed gums?
It may temporarily relieve pain and swelling, but is not a substitute for professional therapy.

How long does gingivitis last?
With good hygiene and professional cleaning, it can regress in 7–14 days. If left untreated, it can become chronic or progress to periodontitis.

Can gingivitis be completely cured?
Yes, if diagnosed and treated early. Periodontitis, on the other hand, can only be controlled, not completely cured.

Dentist's advice

“The gums are the foundation of the smile.
Don't wait for pain to intervene: bleeding is already a warning sign.
Regular cleaning and a biannual check-up at the dentist are the best prevention.”
— Dr. Pietro Pastore, CleanOS dentist

Taking care of your gums is an investment in your health.
Proper daily hygiene and regular dental check-ups can prevent gingivitis, avoid periodontitis, and maintain a healthy smile for a long time.
