A sinus toothache is the result of a sinus infection, according to the Mayo Clinic. If a person is experiencing a sinus toothache, the way to treat the tooth pain is to address the sinus infection. Eliminating the sinus infection will result in toothache relief. A sinus infection causes inflammation in the nasal cavity, placing pressure on the different parts of the body near the sinuses such as the upper teeth. A proper diagnosis is necessary by a dentist to confirm the toothache is the result of a sinus infection. If it is from sinusitis, the dentist will recommend the patient to see his primary care giver for the best treatment.
Over-the-counter pain relievers are used to address the pain associated with the toothache and sinus pressure pain, according to the Mayo Clinic. Non-steroid, anti-inflammatory drugs (NAIDs) are considered the most effective because they relieve pain and reduce inflammation at the same time. Because a sinus toothache is the result of inflamed sinuses, NAIDs help by alleviating pain and shrinking the sinus cavity. Before a person takes any medication, he should talk with his doctor.
Decongestants restrict blood flow to the sinus cavity, causing the sinuses to shrink to their normal size. The Mayo Clinic states that decongestants come in various forms and are only recommended for short-term use as they can result in the nasal congestion getting worse if used too much.
Medline Plus states that a person can self-treat a sinus toothache with natural approaches. A person can apply a warm washcloth to the face, directly over the nose and eyes a few times a day. Steam is used two to four times a day to help moisten the sinuses to reduce inflammation. Steam can be used by taking a hot shower or a person placing her head over a pot of boiling water. Saline is used in the form of a nasal spray or nasal wash, according to the Mayo Clinic. This helps to cleanse the sinus cavity and provide moister. The use of a humidifier can also help to moisten and calm the inflamed sinuses.
If the sinus toothache is the result of sinus pressure from chronic allergies, the person should avoid all known allergy triggers to reduce the amount of nasal reactions. The use of antihistamines is also used to prevent and treat sinus allergy symptoms that can lead to a sinus toothache. In rare cases, a doctor may recommend allergy shots for people suffering from severe allergies.
