Can antibiotics cure periodontal infection?

Periodontal infection, also known as periodontal disease or gum disease, is a common oral health issue that affects millions of people worldwide. It occurs when the gums become infected and inflamed due to the buildup of bacteria on the surface of the teeth. If left untreated, periodontal infection can lead to severe tissue and tooth damage, making it important to seek proper treatment. One effective treatment option for periodontal infection is the use of antibiotics. In this blog post, we will explore how antibiotics can be used to treat periodontal infection, their effectiveness, potential side effects, and alternative treatment options.

Overview of Periodontal Infection

Periodontal infection is caused by the accumulation of bacteria and plaque on the teeth and gums. Poor oral hygiene practices, such as inadequate brushing and flossing, can contribute to the development of this condition. Additionally, certain risk factors, such as smoking, hormonal changes, diabetes, and genetic predisposition, can increase the likelihood of developing periodontal infection.

Symptoms of periodontal infection may include red, swollen, and tender gums, bleeding gums while brushing or flossing, persistent bad breath, receding gums, and loose teeth. If left untreated, periodontal infection can progress to more severe stages, leading to bone loss, tooth mobility, and eventually tooth loss.

Antibiotics for Periodontal Infection

Antibiotics are medications that can be used to treat bacterial infections, including periodontal infection. They work by killing or inhibiting the growth of bacteria responsible for the infection. When it comes to treating periodontal infection, antibiotics are often used in conjunction with other non-surgical treatments, such as scaling and root planing.

There are several commonly used antibiotics for periodontal infection, including:


Tetracycline is an antibiotic that effectively targets the bacteria associated with periodontal infection. It inhibits protein synthesis in bacteria, preventing their growth and spreading. Tetracycline can be administered either in the form of a topical gel or taken orally.


Metronidazole is another commonly prescribed antibiotic for periodontal infection. It has a bactericidal effect, meaning it kills the bacteria responsible for the infection. Metronidazole is typically used in combination with other antibiotics to provide broad-spectrum coverage.


Amoxicillin is a broad-spectrum antibiotic that is often used to treat various bacterial infections, including periodontal infection. It works by interfering with the formation of bacterial cell walls, leading to their destruction. Amoxicillin is generally well-tolerated and is available in tablet or capsule form.

Effectiveness of Antibiotics in Treating Periodontal Infection

Numerous research studies have demonstrated the effectiveness of antibiotics in treating periodontal infection. A study published in the Journal of Clinical Periodontology found that patients treated with a combination of antibiotics and non-surgical treatments experienced significant improvements in periodontal health compared to those who only received non-surgical treatments.

The success rates of antibiotic treatment for periodontal infection can vary depending on factors such as the severity of the infection, patient compliance with medication, and proper oral hygiene practices. Generally, antibiotics can help reduce inflammation and kill the bacteria responsible for periodontal infection, leading to improved gum health and prevention of further damage.

It is important to note that while antibiotics can be effective in treating periodontal infection, they are typically part of a comprehensive treatment plan that includes professional dental care, proper oral hygiene practices, and regular follow-up visits with a dentist or periodontist.

Combination Therapies

In some cases, antibiotics may be used in combination with non-surgical treatments for periodontal infection. Non-surgical treatments, such as scaling and root planing, involve the removal of plaque and tartar from the teeth and root surfaces. The addition of antibiotics can help target and eliminate any remaining bacteria, enhancing the effectiveness of the treatment.

Combining antibiotics with non-surgical treatments can provide several benefits. It can help reduce inflammation, control infection, promote healing, and prevent further damage to the gums and supporting structures. Additionally, the use of combination therapies can help improve treatment outcomes and reduce the need for more invasive procedures.

Potential Side Effects and Considerations

Like any medication, antibiotics can have potential side effects and considerations. Common side effects of antibiotic treatment may include nausea, diarrhea, stomach upset, and allergic reactions. It is important to follow the recommended dosage and duration of antibiotics to minimize the risk of side effects.

Another consideration is the development of antibiotic resistance. Over time, bacteria can become resistant to antibiotics, making them less effective in treating infections. To minimize the risk of antibiotic resistance, it is crucial to use antibiotics judiciously, follow the prescribed treatment plan, and only use antibiotics when necessary.

Precautions and Recommendations

When using antibiotics for periodontal infection, it is important to take certain precautions and follow recommendations for optimal results. Some of the key precautions and recommendations include:

Proper usage and dosage:

Follow the prescribed dosage and instructions provided by your dentist or healthcare professional. Take the antibiotics as directed and complete the full course of treatment.

Importance of follow-up care:

After completing the antibiotic treatment, it is crucial to schedule follow-up visits with your dentist or periodontist. Regular check-ups can help monitor the progress of the treatment, assess the healing process, and make any necessary adjustments to the treatment plan.

Maintenance of good oral hygiene:

Along with antibiotic treatment, maintaining good oral hygiene practices is vital. Brush your teeth at least twice a day, floss regularly, and use an antimicrobial mouthwash to help control bacterial growth.

Alternative Treatment Options

While antibiotics can be effective in treating periodontal infection, there are also alternative treatment options available. Non-antibiotic treatments for periodontal infection may include:

– Mechanical removal of plaque and tartar through scaling and root planing
– Laser therapy to remove infected tissue and promote healing
– The use of antimicrobial agents, such as antiseptic mouthwashes or gels, to help control bacterial growth

Additionally, there are natural remedies and adjunctive therapies that can help support periodontal health. These may include oil pulling, saltwater rinses, herbal remedies, and vitamins and supplements that support gum health. However, it is important to note that these alternative treatments should not be used as a substitute for professional dental care and antibiotic treatment when necessary.


Antibiotics can be an effective treatment option for periodontal infection. They help eliminate bacteria, reduce inflammation, and promote gum healing. However, it is essential to use antibiotics as part of a comprehensive treatment plan that includes professional dental care and proper oral hygiene practices. While antibiotics can provide significant benefits, it is also important to consider potential side effects, antibiotic resistance, and alternative treatment options. If you suspect that you have periodontal infection, it is crucial to seek professional dental care for an accurate diagnosis and suitable treatment. Proper treatment and maintenance can help preserve your oral health and prevent further damage caused by periodontal infection.
