Can a upper tooth extraction effect sinus?

Yes, an upper tooth extraction can affect the sinus. The maxillary sinuses are located just above the upper teeth, and the roots of the upper teeth can extend into the sinuses. If a tooth is extracted, it can create an opening between the mouth and the sinus, which can lead to a condition called sinusitis. Sinusitis can cause a variety of symptoms, including nasal congestion, facial pain, headache, and fever. In some cases, sinusitis can also lead to more serious complications, such as meningitis and brain abscess.

If you are considering having an upper tooth extracted, it is important to talk to your dentist about the risks and benefits of the procedure. Your dentist will be able to determine if you are at risk for developing sinusitis and will take steps to minimize the risk of complications.
