Oral Health: White Bumps Near Wisdom Teeth Explained - Dentistry

Near the wisdom teeth?


Hello, doctor.
Recently, I've noticed small bumps (about 1mm in size) on the tissue behind the last tooth on both sides of my lower jaw.
I've been feeling them with my tongue and fingers for the past week or two.
When I shine a flashlight on them, they appear to be white.
Could you please tell me what these might be? I've also been dealing with a cold and a persistent cough that hasn't improved.
I had a sore throat a while back, but now I only have the cough.
Could this be related to inflammation?

The above situation may be due to the oral mucosa being affected by a virus or the immune system being disrupted due to excessive emotional stress or lack of sleep, leading to an inflammatory response.
If daily routines are normalized, the symptoms will gradually disappear as the cold slowly recovers.

The presence of white bumps or small white particles near your wisdom teeth can be concerning, and it's important to understand the potential causes and implications for your oral health. Based on your description, these white bumps could be attributed to several factors, including inflammation, infection, or even benign conditions.

One common cause of white bumps in the oral cavity, especially near the wisdom teeth, is the formation of oral mucosal lesions, which can occur due to irritation or trauma. This irritation might be caused by the wisdom teeth themselves, particularly if they are partially erupted or impacted. When teeth do not fully emerge, they can create pockets where food particles and bacteria accumulate, leading to inflammation and the formation of white lesions or bumps.

Another possibility is that these white bumps are related to a condition known as oral thrush, which is a fungal infection caused by an overgrowth of Candida yeast. This condition often presents as white patches or bumps in the mouth and can be associated with a weakened immune system, which might explain your recent cold and persistent cough. If your immune system is compromised, it can lead to an increased risk of infections, including oral thrush.

Additionally, the bumps could be a sign of a condition called leukoplakia, which is characterized by white patches on the mucous membranes of the mouth. While leukoplakia can be benign, it can also be a precursor to oral cancer, especially if the patches are persistent and cannot be easily wiped away. Therefore, it is crucial to have any new or unusual oral lesions evaluated by a dental professional.

Given your recent symptoms of a sore throat and persistent cough, it is also possible that the bumps are related to a viral infection that has caused inflammation in the oral cavity. Viral infections can lead to various oral manifestations, including lesions and bumps, especially if there is concurrent inflammation of the throat.

To address your concerns, it is advisable to schedule an appointment with a dentist or an oral health specialist. They can perform a thorough examination, possibly including imaging studies, to determine the exact nature of the white bumps and whether any treatment is necessary. In the meantime, maintaining good oral hygiene is essential. This includes brushing your teeth at least twice a day, flossing daily, and using an antiseptic mouthwash to help reduce bacteria in the mouth.

If you experience any pain, difficulty swallowing, or if the bumps change in appearance or persist for more than a couple of weeks, seek medical attention promptly. Additionally, if you have any underlying health conditions or are taking medications that may affect your immune system, be sure to inform your healthcare provider, as this information can be crucial in diagnosing and treating your condition effectively.

In summary, while the white bumps near your wisdom teeth could be due to various causes, including irritation, infection, or other oral health issues, it is essential to consult with a dental professional for an accurate diagnosis and appropriate treatment. Taking proactive steps in your oral care and addressing any underlying health concerns will help you maintain optimal oral health and prevent further complications.
