Feeling under the weather is bad enough, but when your teeth start aching during illness, it can make you wonder why do my teeth hurt when i’m sick? This common experience affects millions of people, and understanding the connection between illness and dental pain can help you manage symptoms more effectively.
The Connection Between Sickness and Tooth Pain
When you’re battling a cold, flu, or sinus infection, your body undergoes various changes that can directly impact your teeth and gums. The why do my teeth hurt when i’m sick phenomenon occurs due to several interconnected factors that create perfect conditions for dental discomfort.
Primary Causes of Tooth Pain During Illness
Sinus Pressure and Congestion
One of the main reasons why do my teeth hurt when i’m sick relates to sinus congestion. Your upper teeth sit very close to your maxillary sinuses, and when these air-filled cavities become inflamed and blocked, they create pressure that radiates to nearby teeth.
| Sinus Location | Affected Teeth | Pain Type |
|---|---|---|
| Maxillary Sinuses | Upper molars and premolars | Dull, throbbing ache |
| Frontal Sinuses | Upper front teeth | Sharp, stabbing pain |
| Ethmoid Sinuses | Multiple upper teeth | Generalized discomfort |
Dehydration Effects
Illness often leads to dehydration, which reduces saliva production. This dry mouth condition creates an environment where bacteria thrive, potentially causing tooth sensitivity and pain.
How Inflammation Affects Your Teeth
Systemic Inflammation Response
When your body fights infection, it produces inflammatory compounds that travel throughout your system. These substances can reach your gums and tooth structures, explaining why do my teeth hurt when i’m sick even when the original infection isn’t dental-related.
Blood Flow Changes
Fever and illness alter blood circulation patterns, potentially increasing sensitivity in dental nerves and causing previously unnoticed dental issues to become painful.
Specific Illnesses and Tooth Pain

Sinus Infections
Sinusitis is perhaps the most common cause when people ask why do my teeth hurt when i’m sick. The infected sinuses press directly against tooth roots, creating referred pain that feels like a toothache.
