After biting down on something hard, my teeth, gums, and the area near my nose feel uncomfortable?

One day, after biting into something hard, I felt a strange sensation in my upper canine and first premolar, as well as in the gums above them extending towards the area near my nose.
It wasn't painful, but there was a feeling of pressure and fullness.
The dentist took X-rays and said there didn't seem to be any issues (these two teeth are also relatively far from the sinuses), and the ENT specialist also indicated that it didn't seem to be sinusitis.
What other possibilities could there be?

More Info

Experiencing discomfort after biting into hard foods can be a perplexing issue, especially when dental examinations and X-rays do not reveal any apparent problems. The sensation you describe—feeling a dull, swollen sensation around the upper canine and first premolar, extending towards the nasal area—could stem from several underlying dental or anatomical factors.

Firstly, it is essential to consider the possibility of microfractures in the teeth. Even if X-rays do not show any visible cracks, small fractures can occur in the enamel or dentin that may not be easily detectable. These microfractures can lead to sensitivity or discomfort when biting down, especially on hard foods. The pressure exerted during chewing can exacerbate these issues, causing a sensation of discomfort or pressure in the surrounding tissues.

Another potential cause could be related to the dental pulp or the nerves within the teeth. If the pulp is inflamed or irritated—possibly due to previous trauma or extensive dental work—it can lead to a sensation of pressure or discomfort that radiates to the surrounding areas, including the gums and even the sinus region. This is sometimes referred to as "referred pain," where the discomfort is felt in a different location than the actual source of the problem.

Additionally, the periodontal tissues surrounding the teeth could be a contributing factor. If there is any inflammation or irritation in the gums, it can lead to a feeling of pressure or discomfort. This could be exacerbated by food particles getting trapped between the teeth, leading to localized inflammation. Proper oral hygiene, including regular flossing and brushing, is crucial to prevent such issues.

Another consideration is the possibility of bruxism, or teeth grinding, which can occur unconsciously, especially during sleep. This condition can lead to wear on the teeth, increased sensitivity, and discomfort in the jaw and surrounding areas. If you have a history of grinding your teeth, it may be worth discussing this with your dentist, as they may recommend a night guard to protect your teeth.

Lastly, while you mentioned that an ENT specialist ruled out sinusitis, it is worth noting that dental issues can sometimes mimic sinus problems. The roots of the upper teeth, particularly the canine and premolars, are located close to the maxillary sinuses. In some cases, dental infections or issues can lead to referred pain that feels similar to sinus discomfort.

In conclusion, if the discomfort persists, it is advisable to seek further evaluation from your dentist. They may consider additional diagnostic tools, such as a cone beam CT scan, which provides a more detailed view of the dental and surrounding structures. Furthermore, discussing your symptoms in detail with your dentist can help them pinpoint the issue more accurately. Keeping track of when the discomfort occurs and any associated activities (like eating hard foods) can also provide valuable information for your dental care provider.
