Why Do Gums Swell? Causes and Treatments

Saturday, May 09, 2026

SAEDNEWS: Food particles and dental plaque accumulate in narrow and deep grooves that are usually present on the occlusal (chewing) surfaces of posterior teeth. The buildup of these materials can lead to swelling or inflammation of the gums.

Why Do Gums Swell? Causes and Treatments

According to Saed News and Behdasht News:

Causes of Gum Swelling

Gum swelling and inflammation are usually caused by bacterial infection. If left untreated, this inflammation can lead to a condition called periodontitis. Gum swelling and periodontitis are among the main causes of tooth loss in adults.

If gum swelling is not treated, the gums may separate from the teeth, damaging the soft tissues and bone structure supporting the teeth. As a result, teeth may become loose, and if the infection progresses, tooth loss may occur.


Risk Factors for Gum Swelling

Risk factors include:

  • Smoking or chewing tobacco

  • Diabetes

  • Certain medications (oral contraceptives, steroids, anticonvulsants, calcium channel blockers, chemotherapy drugs)

  • Misaligned teeth

  • Improper dental appliances

  • Broken fillings

  • Pregnancy

  • Genetic factors

  • Weakened immune system (e.g., AIDS)


Symptoms of Gum Swelling

Common symptoms include:

  • Red and swollen gums

  • Bleeding during brushing or flossing

  • Gum recession (pulling away from teeth)

  • Loose teeth

  • Changes in bite alignment

  • Pus between teeth and gums

  • Pain while chewing

  • Tooth sensitivity

  • Bad breath


Diagnosis of Gum Swelling

During a dental examination, gums are checked using a small probe to detect inflammation, pockets, or gaps around the teeth. Dental X-rays may also be used to assess bone and tooth stability.


Treatment of Gum Swelling

Treatment focuses on improving oral hygiene and eliminating infection. Smoking cessation and diabetes control are also important.

Treatment options include:

1. Dental Cleaning Procedures

  • Scaling: Removal of plaque and tartar above and below the gum line

  • Root planing: Smoothing the root surfaces and removing tartar from tooth roots

  • Laser treatment: A less painful option with reduced bleeding

2. Medications

  • Antiseptic mouthwash containing chlorhexidine

  • Chlorhexidine gels after root planing

  • Antibiotics such as minocycline and doxycycline (oral or local use)

3. Surgery

  • Flap surgery: Temporarily lifting the gums to clean deep areas

  • Bone and tissue grafting: Used in severe damage to gums and jawbone


Home Remedies for Gum Swelling

  • Do not swallow

  • Spit out, rinse mouth, drink water, and brush teeth afterward


Summary

Gum swelling is a common but potentially serious condition. Early treatment, proper oral hygiene, and lifestyle changes can prevent complications such as periodontitis and tooth loss.
