What causes gum pain?

The main causes of gum pain are:

1. Poor oral hygiene

Poor oral hygiene habits, such as lack of brushing or brushing too hard, can cause gum bleeding, inflammation and infection, which can lead to gum pain.

What to do: It is essential to maintain good oral hygiene by brushing your teeth at least twice a day, especially after meals, and using dental floss and mouthwash. Furthermore, it is also important to brush your teeth without using too much force, preferably using a soft brush, to prevent gum damage.

2. Gingivitis

Gingivitis is characterized by gum inflammation due to the accumulation of bacterial plaque on the teeth. It causes gum pain between the teeth, bleeding, swelling and redness. Gingivitis usually happens due to poor oral hygiene, but it can also be due to other factors such as cracked or broken teeth, changes in hormones, cancer, alcohol, stress, poor diet, or insufficient saliva production.

What to do: It is important that to consult a dentist as soon as you notice symptoms of gingivitis so that treatment can be started immediately. Adequate measures can prevent the development of periodontitis. Typically, gingivitis is treated by performing a complete dental cleaning, although in some cases, antibiotics may be prescribed.

3. Use of braces and dentures

Braces and dentures can also cause gum pain, as the use of this equipment can lead to a greater risk for he accumulation of food debris and microorganisms. These can lead infection and, consequently, pain, swelling and bleeding in the gums. Furthermore, if these devices are poorly fitted, they can cause swelling, inflammation and pain in the jaw or teeth.

What to do: In these cases, it is especially important to maintain adequate oral hygiene to avoid the accumulation of food debris. It is also important to report ill-fitting dentures or braces to your dentist. You should follow-up with your dentist regularly for maintenance and reassessment.

5. Wisdom tooth rupture

The growth of wisdom teeth, which usually happens between the ages of 17 and 21, can also cause pain and immense discomfort in the gums at the back of the mouth.

During puberty and pregnancy, blood flow increases to the gums, making them more swollen, sensitive or painful. During menopause, hormone levels decrease, which can cause bleeding and pain in the gums, as well as changes to color.

What to do: You should consult a gynecologist to assess hormonal levels as well as any other possible symptoms. A complete and thorough assessment will help to guide treatment.
