\u2013 Sinus Perforation &amp; Tooth-Related Sinus Pain<\/h1>\n\n<p>If you need <strong>dental sinusitis treatment in Stockholm<\/strong>, the cause may be an infected upper tooth, a failed root canal, gum infection around an upper molar, or a small opening between the mouth and the sinus after extraction. These conditions can create one-sided sinus pressure, toothache, bad taste, nasal symptoms, or fluid passing between the mouth and nose.<\/p>\n\n<p>At Gloss &amp; Floss Dental Care\u00ae in S\u00f6dermalm, we assess tooth-related sinus problems with a structured dental and oral-surgery approach. The aim is to identify the dental source, reduce infection risk, protect the maxillary sinus, and support predictable healing. When needed, we coordinate further assessment with medical or ENT care.<\/p>\n\n<p>This page explains <strong>dental sinusitis<\/strong>, <strong>sinus perforation<\/strong>, <strong>oral-antral communication<\/strong>, treatment options, aftercare, and when to seek urgent dental help.<\/p>\n\n<p style=\"font-size:0.95em; color:#ffffff;\"><strong>Reviewed by:<\/strong> Gloss &amp; Floss Dental Care. <strong>Last updated:<\/strong> May 2026.<\/p>\n\n<div style=\"border:1.5px solid #d6a622; background:#fffaf0; color:#111111; padding:20px; border-radius:10px; margin:28px 0;\">\n<h2 style=\"margin-top:0; color:#c99a13;\">Quick answer \u2013 dental sinusitis vs sinus perforation<\/h2>\n<ul>\n<li><strong>Dental sinusitis:<\/strong> sinus inflammation caused by a dental source, often an infected upper molar or premolar.<\/li>\n<li><strong>Sinus perforation:<\/strong> a small opening between the mouth and the maxillary sinus, often after extraction of an upper back tooth.<\/li>\n<li><strong>Oral-antral communication, OAC:<\/strong> the clinical term for an opening between the mouth and sinus.<\/li>\n<li><strong>Oroantral fistula, OAF:<\/strong> a persistent opening that has not closed and may need surgical management.<\/li>\n<li><strong>Urgent warning signs:<\/strong> fluid passing from mouth to nose, worsening facial swelling, fever, foul taste, or one-sided sinus symptoms after dental treatment.<\/li>\n<\/ul>\n<p style=\"margin-bottom:0;\"><strong>Best next step:<\/strong> book a dental assessment if symptoms are connected to an upper tooth, previous root canal treatment, or recent extraction.<\/p>\n<\/div>\n\n<hr style=\"border:0; border-top:1px solid rgba(255,255,255,0.25); margin:30px 0;\" \/>\n\n<h2>What is dental sinusitis?<\/h2>\n\n<p><strong>Dental sinusitis<\/strong>, also called <strong>odontogenic sinusitis<\/strong> or <strong>tooth-related sinusitis<\/strong>, occurs when infection or inflammation from an upper tooth affects the maxillary sinus. The roots of upper premolars and molars can sit very close to the sinus floor. This means that a dental infection may feel like sinus pressure, cheek pain, nasal blockage, or upper jaw discomfort.<\/p>\n\n<p>Dental sinusitis is often one-sided. It may be linked to deep decay, an infected tooth nerve, a failed or leaking root canal, periodontal disease around upper teeth, or complications after dental surgery.<\/p>\n\n<p>Because ordinary sinusitis and dental sinusitis can feel similar, a focused dental assessment is important. Treating only the sinus symptoms without addressing the dental source may lead to repeated symptoms.<\/p>\n\n<hr style=\"border:0; border-top:1px solid rgba(255,255,255,0.25); margin:30px 0;\" \/>\n\n<h2>What is a sinus perforation after tooth extraction?<\/h2>\n\n<p>A <strong>sinus perforation<\/strong> can occur when an upper premolar or molar is removed and a small communication forms between the mouth and the maxillary sinus. This is called an <strong>oral-antral communication<\/strong> or <strong>OAC<\/strong>.<\/p>\n\n<p>Small openings can sometimes close with protective measures and careful follow-up. Larger openings, infected openings, or openings that persist may require surgical closure to prevent an <strong>oroantral fistula<\/strong>.<\/p>\n\n<p>If you notice air, fluid, or pressure moving between your mouth and nose after an extraction, do not test the area by forcing air through the nose. Contact a dentist for assessment.<\/p>\n\n<hr style=\"border:0; border-top:1px solid rgba(255,255,255,0.25); margin:30px 0;\" \/>\n\n<h2>Dental sinusitis treatment Stockholm \u2013 symptoms to watch for<\/h2>\n\n<p>Symptoms may be dental, sinus-related, or both.

Regular sinusitis usually starts in the sinus or upper airway. Dental sinusitis starts from a tooth or dental infection and often affects one side. Treating the dental source is important for lasting improvement.<\/p>\n\n<h3>Can a tooth infection cause sinus pain without toothache?<\/h3>\n<p>Yes. Some patients mainly feel one-sided sinus pressure, bad taste, or nasal symptoms and do not have strong tooth pain. Dental imaging and tooth testing can help identify the source.<\/p>\n\n<h3>Can a failed root canal cause sinus problems?<\/h3>\n<p>Yes. A re-infected or poorly sealed root canal in an upper tooth can irritate the maxillary sinus. Treatment may involve root canal retreatment, apical surgery, or extraction depending on the tooth prognosis.<\/p>\n\n<h3>How do I know if I have a sinus perforation after extraction?<\/h3>\n<p>Possible signs include air or liquid passing between the mouth and nose, whistling when speaking, fluid leaking from the nose when drinking, or persistent bad taste after extraction. Contact the clinic if this happens.<\/p>\n\n<h3>Is sinus perforation dangerous?<\/h3>\n<p>A small perforation can sometimes heal with protective measures, but it must be monitored. Larger or persistent openings can lead to an oroantral fistula or sinus infection and may need surgical closure.<\/p>\n\n<h3>Do all sinus perforations need surgery?<\/h3>\n<p>No. Very small openings may close with careful suturing, sinus precautions, and follow-up. Larger openings, infected openings, or openings that persist are more likely to need surgical closure.<\/p>\n\n<h3>What should I avoid after a sinus perforation?<\/h3>\n<p>Avoid nose blowing, sneezing with a closed mouth, drinking through straws, smoking, heavy lifting, and testing the opening by forcing air through the nose. Follow the clinic\u2019s aftercare instructions.<\/p>\n\n<h3>Can I fly after a sinus perforation or sinus-related dental surgery?<\/h3>\n<p>You should ask the treating dentist before flying. Pressure changes may disturb healing in some cases, especially if there is an open communication or recent surgical closure.<\/p>\n\n<h3>Should I see a dentist or an ENT specialist?<\/h3>\n<p>Start with a dentist if symptoms are linked to upper teeth, root canal treatment, extraction, or dental surgery. ENT care may be needed if sinus disease persists or if the symptoms suggest a non-dental sinus condition.<\/p>\n\n<h3>Can I get dental implants after dental sinusitis or sinus perforation?<\/h3>\n<p>Often yes, but only after infection has resolved and healing is stable. If bone height is limited, a sinus lift may be considered before implant placement.<\/p>\n\n<h3>When should I seek urgent help?<\/h3>\n<p>Seek urgent help if you have fever, spreading swelling, severe pain, fluid passing between mouth and nose, foul drainage, or worsening symptoms after extraction or dental surgery.<\/p>\n\n<\/div>\n\n<hr style=\"border:0; border-top:1px solid rgba(255,255,255,0.25); margin:30px 0;\" \/>\n\n<h2>Book dental sinusitis treatment in Stockholm<\/h2>\n\n<p>If you have one-sided sinus pressure, upper tooth pain, symptoms after an upper molar extraction, or signs of a sinus perforation, book an assessment at Gloss &amp; Floss Dental Care\u00ae in S\u00f6dermalm.
