Throat Irritation And Cough
As discharge from your sinuses drains down the back of your throat, it can cause irritation, especially over a long period of time. This can lead to a persistent and annoying cough, which can be worse when lying down to sleep or first thing in the morning after getting up from bed.
It can also make sleeping difficult. Sleeping upright or with your head elevated can help reduce the frequency and intensity of your coughing.

A sinus infection can create pressure and pain in the mouth and cause a sinus tooth pain. Specifically, this is due to pressure and pain in the maxillary sinuses located behind the cheekbones. Sinus tooth pain is often confused with other causes of tooth pain, including gum disease, tooth decay, or an impacted wisdom tooth.
What Causes Sinus Infections?
A sinus infection occurs when bacteria from the nose enter the sinuses. To help you assess whether you have a sinus tooth pain or a toothache caused by something else, take note of symptoms that occur in addition to pain around the upper teeth, eyes, or cheekbones.

What Is The Function Of The Sinuses
The human skull contains four major pairs of hollow air-filled cavities called sinuses. These are connected to the space between the nostrils and the nasal passage . Sinuses help insulate the skull, reduce its weight, and allow the voice to resonate within it. The four major pairs of sinuses are:
The sinuses contain defenses against viruses and bacteria . The sinuses are covered with a mucous layer and cells that contain tiny hairs on their surface that help trap and propel bacteria and pollutants outward.
Acute sinusitis typically lasts less than eight weeks or occurs no more than three times per year with each episode lasting no longer than 10 days. Medications are generally effective against acute sinusitis. Successful treatment counteracts damage done to the mucous lining of the sinuses and surrounding bone of the skull.
Chronic or recurring sinusitis lasts longer than eight weeks or occurs more than four times per year, with symptoms usually lasting more than 20 days.
Sore Throat And Hoarse Voice
Postnasal drip can leave you with a raw and aching throat. Although it may start as an annoying tickle, it can get worse.
If your infection lasts for a few weeks or more, mucus can irritate and inflame your throat as it drips, resulting in a painful sore throat and hoarse voice. Frequent coughing and throat clearing can make a hoarse voice worse.

Pain Or Pressure In Your Sinuses
Facial pain is a common symptom of sinusitis. You have several different sinuses above and below your eyes, as well as behind your nose. Any of these air-filled cavities can hurt when you have a sinus infection.
Inflammation and swelling can cause your sinuses to ache with dull pressure. This is because inflammation may alter the typical path of mucus from the nose to the back of the throat.
You may feel pain in:
- your forehead
- on either side of your nose
- in your upper jaws and teeth
- between your eyes
This may lead to a headache. Headaches caused by sinus infections can occur where the sinuses are or in other places.
What Causes Sinus Infections And Sinusitis
Causes of Acute Sinus Infections
- Acute sinusitis usually follows a viral infection in the upper respiratory tract, but allergy-causing substances or pollutants may also trigger acute sinusitis. A Viral infection damages the cells of the sinus lining, leading to inflammation. The lining thickens, obstructing the nasal passage. This passage connects to the sinuses. The obstruction disrupts the process that removes bacteria normally present in the nasal passages, and the bacteria begin to multiply and invade the lining of the sinus. This causes the symptoms of sinus infection. Allergens and pollutants produce a similar effect.
- Bacteria that normally cause acute sinusitis are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. These microorganisms, along with Staphylococcus aureus and some anaerobes , are involved in chronic sinusitis.
Causes of Chronic Sinus Infections
- Chronic sinus infections are caused by viruses, bacteria, allergens, pollutants, and fungal infections, especially people with diseases that weaken the immune system, for example, HIV/AIDS, leukemia and other cancers, and diabetes.
- Medications that are designed to modify the immune system may increase the risk of developing sinus infections.
- Ongoing bad breath unrelated to dental problems
People who have facial pain, headaches, and fever may indicate a sinus infection.

- Avoid contracting upper respiratory tract infections. Maintain strict hand washing habits and avoid people who are suffering from a cold or the flu.
- Obtaining the flu vaccination yearly will help to prevent the flu and subsequent infection of the upper respiratory tract.
- In some studies, zinc carbonate lozenges have been shown to reduce the duration of many cold symptoms.
- Stress reduction and a diet rich in antioxidants, especially fresh, dark-colored fruits and vegetables, may help strengthen the immune system.
- Plan for seasonal allergy attacks.
- If a sinus infection is caused by seasonal or environmental allergies, avoiding allergens is very important. If avoidance is not an option, either OTC or prescription medication may be helpful. OTC antihistamines or decongestant nasal sprays can be used for an acute attack.
- People who have seasonal allergies may benefit from nonsedating prescription antihistamines during allergy-season.
- Avoid spending long periods outdoors during allergy season. Close the windows to the house and use air conditioning to filter out allergens when possible. Humidifiers may also be helpful.
- Allergy shots, also called “immunotherapy,” may be effective in reducing or eliminating sinusitis due to allergies. An allergist administers shots regularly for 3 to 5 years, which often produces a reduction or complete remission of allergy symptoms for years.
