Oral issues


Doctor, why has the tissue next to my teeth been swelling easily lately? Also, the tissue behind my lower teeth is swollen and has a bit of bleeding.
Why is this happening?

Dr. Zeng Guanghui reply Dentistry


Hello, sir: Thank you for your inquiry.
I would like to address your question and provide the following advice: Swelling of the gums is most likely due to bacterial plaque infection, which causes an inflammatory response in the gums, making them sensitive and prone to bleeding.
It is recommended to thoroughly clean your teeth and interdental spaces to remove dental plaque, as this will naturally improve the inflammatory condition.
However, if the inflammation is severe, it is necessary to consult a dentist for mechanical cleaning.
Finally, I wish you peace and happiness!

Gum swelling and bleeding are common dental issues that can arise from various underlying causes. Understanding these causes is crucial for effective treatment and prevention.
Firstly, gum swelling, also known as gingival swelling, can occur due to inflammation of the gums, often a result of gingivitis. Gingivitis is typically caused by the accumulation of plaque—a sticky film of bacteria that forms on the teeth. When plaque is not removed through regular brushing and flossing, it can irritate the gum tissue, leading to swelling, redness, and bleeding, particularly when brushing or flossing. This condition is usually reversible with good oral hygiene practices, including regular brushing, flossing, and professional dental cleanings.

In your case, the swelling and bleeding around your teeth could indicate the presence of gingivitis or even more advanced periodontal disease, known as periodontitis. Periodontitis occurs when gingivitis is left untreated, leading to the destruction of the supporting structures of the teeth, including the bone. This can result in deeper pockets forming between the teeth and gums, which can harbor more bacteria and exacerbate the condition.

Another potential cause of gum swelling and bleeding is the presence of dental abscesses. An abscess is a localized infection that can occur at the root of a tooth or in the surrounding gum tissue. This can happen due to untreated cavities, gum disease, or trauma to the tooth. Symptoms of an abscess may include swelling, pain, and sometimes a discharge of pus. If you notice a persistent swelling that does not improve, it is essential to seek dental care promptly, as abscesses can lead to more severe complications if left untreated.

Additionally, hormonal changes, such as those occurring during pregnancy or menstruation, can make gums more sensitive and prone to swelling and bleeding. Certain medical conditions, such as diabetes or blood disorders, can also affect gum health and increase the risk of periodontal disease. Medications that cause dry mouth can further exacerbate gum issues, as saliva plays a crucial role in neutralizing acids and washing away food particles and bacteria.

To address your concerns, it is essential to maintain a consistent oral hygiene routine. This includes brushing your teeth at least twice a day with fluoride toothpaste, flossing daily to remove plaque between teeth, and visiting your dentist regularly for check-ups and cleanings. If you are experiencing persistent swelling and bleeding, it is advisable to schedule an appointment with a dentist or a periodontist. They can perform a thorough examination, possibly including X-rays, to determine the underlying cause of your symptoms and recommend appropriate treatment.

In summary, gum swelling and bleeding can result from various factors, including plaque accumulation, periodontal disease, dental abscesses, hormonal changes, and certain medical conditions. Maintaining good oral hygiene and seeking professional dental care are vital steps in managing and preventing these issues. If you have any further questions or concerns, do not hesitate to reach out to your dental care provider for personalized advice and treatment options.
