What causes green plaque between teeth, and what should be done about it?
Under normal circumstances, green plaque between teeth may be caused by food debris, inadequate oral hygiene, dental calculus, dental plaque, or Pseudomonas aeruginosa infection. Symptoms can often be relieved through improved oral hygiene, proper brushing techniques, professional teeth cleaning, and medication. If abnormalities occur, it is advisable to seek medical attention promptly. Specific causes are analyzed as follows:
1. Food Debris
When food debris remains trapped between teeth, it provides nutrients for bacterial growth, which may lead to plaque formation. Pigments from certain foods may also cause the plaque to appear green. Maintaining good oral hygiene and regular toothbrushing is recommended.
2. Inadequate Oral Hygiene
Insufficient daily oral care—such as incorrect brushing technique or insufficient brushing time—may prevent effective removal of plaque from between teeth. Over time, this accumulation can result in green plaque. It is recommended to improve brushing methods, use proper brushing posture and pressure, and ensure thorough cleaning of each interdental space.
3. Dental Calculus
Dental calculus is a hardened deposit formed by the long-term mineralization of dental plaque, commonly found between teeth and along the gumline, and may appear green or yellowish-brown. Associated symptoms may include gum bleeding and gum recession. Treatment typically involves ultrasonic scaling or manual curettage to remove the calculus and restore gum health.
4. Dental Plaque
Dental plaque refers to a community of bacteria adhering to tooth surfaces, interdental spaces, or dental restorations. It may trigger tooth inflammation, leading to gum bleeding and swelling, and form greenish patches between teeth. Under medical guidance, antibacterial and anti-inflammatory medications such as minocycline hydrochloride capsules, ibuprofen tablets, and metronidazole tablets may be used for treatment.
5. Pseudomonas Aeruginosa Infection
Infection with Pseudomonas aeruginosa may result in green plaque in the mouth. Patients may also experience symptoms such as bad breath, swollen and painful gums. It is recommended to follow medical advice and use anti-infective medications such as fluconazole capsules, nystatin tablets, or cydiodine lozenges. Additionally, maintaining good oral hygiene and undergoing regular dental cleanings can help prevent recurrence.
In daily life, maintaining good oral hygiene habits and scheduling regular dental checkups and cleanings are essential for preventing plaque buildup between teeth and reducing the risk of oral diseases.
