Understanding The Connection Between Tooth Pain and Illness

Experiencing tooth pain during an illness is a common occurrence that can be both bothersome and uncomfortable. Despite its seemingly unrelated nature, there are various reasons why tooth pain accompanies sickness. This article delves into the phenomenon of tooth pain during illness, exploring potential causes and symptoms. Additionally, we’ll discuss preventive measures to alleviate and address tooth pain while you’re unwell.

Possible causes of teeth pain during illness:


It is a condition that occurs when the nasal passages become inflamed and clogged with mucus. This can cause pressure to build up in the sinuses. The upper molars on both sides of the mouth are seated directly underneath the maxillary sinuses. When the sinuses are full and causing pressure, this will often cause the upper molars on one or both sides of the mouth to be painful. To relieve the pressure you can place a damp towel around your nose. If the pain is lasting or consistent, it is important to manage it through nasal decongestants, antibiotics, and other treatment options as prescribed by a doctor.

Tooth infection/ Tooth abscess 

Tooth infections or abscesses may arise when bacteria invade a tooth through a cavity. This invasion can result in severe discomfort and increased sensitivity in the affected tooth, as well as the surrounding teeth and gums. Maintaining a diligent oral hygiene routine, including regular brushing and flossing, is essential in preventing these infections. Furthermore, scheduling regular dental check-ups is vital for preserving excellent oral health and preventing the development of tooth infections or abscesses.

It is a condition characterized by teeth grinding and clenching due to stress and anxiety, often during sleep (sleep-related movement disorder). This can cause damage to the teeth, as well as pain in the jaw and surrounding muscles. To prevent teeth pain caused by bruxism, it is important to manage the underlying condition through the use of mouth guards, relaxation techniques, and stress management

Temporomandibular joint disorder (TMJ)

It is a condition that occurs when there is dysfunction in the joint that connects the jawbone to the skull. This can cause pain in the jaw joint and in the muscles that control jaw movement. Mostly, the pain is temporary and can be relieved with self-management such as through the use of pain medication, physical therapy, and other treatment options as prescribed by a doctor.

Dry Mouth

Saliva plays an important role in lubrication of the mouth which is essential for normal swallowing and speaking. It also neutralizes the acid produced by bacteria in the mouth. When your mouth is dry, your teeth become more vulnerable to decay. In addition, a lack of saliva can also cause discomfort and pain. To prevent a dry mouth from hurting your teeth, it’s necessary to drink plenty of water and avoid alcohol and caffeine. You can also consult your dentist about other treatments, such as saliva substitutes, to help keep your mouth hydrated.

2. Avoid stress because it can exacerbate many conditions such as bruxism and TMJ. Plus, it is important to practice stress-reducing techniques, such as meditation.

3. Consult your dentist If tooth pain persists or worsens. This can help identify the underlying cause and allow for prompt treatment to prevent further discomfort.


In a nutshell, tooth pain during illness can be a bothersome experience, but with proper preventative measures and consultation, it can be alleviated. By maintaining good oral hygiene, avoiding stress, and seeking medical attention early, individuals can prevent tooth pain caused by various illnesses and conditions.
