If you have toothache together with one-sided sinus pressure, bad taste, nasal symptoms or pain when chewing, you should book a dental assessment.<\/p>\n\n<p><strong>Dental sinusitis<\/strong>, also called odontogenic sinusitis, means that sinus symptoms are linked to a dental source. This can happen because the roots of the upper molars and premolars are close to the maxillary sinus. A tooth infection, deep decay, failed root canal treatment, gum infection, extraction complication or other dental problem can sometimes create symptoms that feel like ordinary sinusitis.<\/p>\n\n<p>At Gloss &amp; Floss Dental Care\u00ae in S\u00f6dermalm, Stockholm, we help patients understand whether sinus pressure may be connected to a tooth problem. We assess the teeth, gums, bite, symptoms and dental X-rays when needed, then guide you toward the right next step.<\/p>\n\n<p>If you already suspect dental sinusitis or sinus perforation after a dental procedure, visit our dedicated service page for <a href=\"https:\/\/www.gloss-floss.se\/en\/dental-sinusitis-and-sinus-perforation\/\" target=\"_blank\" rel=\"noopener\">dental sinusitis and sinus perforation treatment<\/a>.<\/p>\n<\/header>\n\n<div style=\"background: #111111; color: #ffffff; border-radius: 14px; padding: 22px; margin: 24px 0;\">\n<h2 style=\"margin-top: 0; color: #ffffff;\">Toothache plus sinus pressure?<\/h2>\n<p style=\"margin-bottom: 14px; color: #ffffff;\">Book a dental assessment if sinus pressure is one-sided, returns repeatedly, is combined with upper tooth pain, bad taste, swelling, pain when chewing, or symptoms that do not improve as expected.<\/p>\n<p style=\"margin-bottom: 0;\">\n<a href=\"https:\/\/www.gloss-floss.se\/en\/dental-consultation\/\" target=\"_blank\" rel=\"noopener\" style=\"display: inline-block; background: #c8a45d; color: #111111; padding: 12px 18px; border-radius: 8px; text-decoration: none; font-weight: bold;\">Book dental assessment<\/a>\n&nbsp;\n<a href=\"https:\/\/www.gloss-floss.se\/en\/emergency-dentalcare\/\" target=\"_blank\" rel=\"noopener\" style=\"display: inline-block; background: #ffffff; color: #111111; padding: 12px 18px; border-radius: 8px; text-decoration: none; font-weight: bold;\">Emergency dental care<\/a>\n<\/p>\n<\/div>\n\n<hr \/>\n\n<h2>Dental sinusitis \u2013 quick overview<\/h2>\n\n<div style=\"background: #f7f7f7; color: #111111; border-left: 4px solid #c8a45d; padding: 18px; margin: 22px 0;\">\n<ul>\n  <li><strong>Dental sinusitis can mimic ordinary sinusitis<\/strong>, but the source is dental.<\/li>\n  <li><strong>Upper molars and premolars are most relevant<\/strong> because they are close to the maxillary sinus.<\/li>\n  <li><strong>One-sided sinus pressure with toothache<\/strong> is an important clue.<\/li>\n  <li><strong>Antibiotics or nasal sprays alone may not solve the problem<\/strong> if the dental source remains untreated.<\/li>\n  <li><strong>Dental assessment, X-rays and panoramic X-ray when needed<\/strong> help identify whether a tooth is involved.<\/li>\n  <li><strong>Treatment may include root canal treatment, retreatment, extraction or oral surgery<\/strong>, depending on the diagnosis.<\/li>\n<\/ul>\n<\/div>\n\n<hr \/>\n\n<section>\n<h2>What is dental sinusitis?<\/h2>\n\n<p>Dental sinusitis is sinus inflammation caused or maintained by a dental problem. It is different from ordinary sinusitis that starts after a cold, allergy or upper respiratory infection.<\/p>\n\n<p>The maxillary sinuses sit above the upper back teeth. In some patients, the roots of these teeth are very close to the sinus floor. If infection develops around a root tip, deep cavity, gum pocket or previous dental treatment, the sinus may become irritated or infected.<\/p>\n\n<p>This is why some patients feel pressure in the cheek, nasal congestion or sinus pain when the real origin is a tooth. The reverse can also happen: ordinary sinus pressure can make upper teeth feel sore even when the teeth are not infected. Careful diagnosis is therefore important.<\/p>\n<\/section>\n\n<hr \/>\n\n<section>\n<h2>Is it sinus pain or tooth pain?<\/h2>\n\n<p>Sinus pain and tooth pain can overlap.

Infection around an upper molar or premolar can irritate the maxillary sinus and cause cheek pressure, nasal symptoms or pain that feels like sinusitis.<\/p>\n\n<h3>How do I know if sinus pain is coming from a tooth?<\/h3>\n<p>One-sided symptoms, upper tooth pain, pain when biting, bad taste, swelling near a tooth or symptoms that do not improve with ordinary sinus treatment may suggest a dental source.<\/p>\n\n<h3>Can ordinary sinusitis make my teeth hurt?<\/h3>\n<p>Yes. Sinus pressure can make several upper back teeth feel sore, especially during a cold or sinus infection. If pain becomes localised to one tooth or persists, dental assessment is recommended.<\/p>\n\n<h3>Does dental sinusitis go away with antibiotics?<\/h3>\n<p>Antibiotics may sometimes reduce symptoms temporarily, but if the dental source remains untreated, symptoms may persist or return. The underlying tooth or gum problem often needs treatment.<\/p>\n\n<h3>How is dental sinusitis diagnosed?<\/h3>\n<p>Diagnosis usually includes symptom review, dental examination, assessment of upper teeth and gums, and dental X-rays or panoramic X-ray when needed. Complex cases may require further imaging or ENT assessment elsewhere.<\/p>\n\n<h3>What treatment is needed for dental sinusitis?<\/h3>\n<p>Treatment depends on the cause. It may include root canal treatment, retreatment, extraction, management of sinus perforation, medication, oral surgery assessment or ENT collaboration.<\/p>\n\n<h3>What is sinus perforation after tooth extraction?<\/h3>\n<p>A sinus perforation means that a small opening has formed between the mouth and the maxillary sinus, often after extraction of an upper molar. It needs prompt dental assessment and specific aftercare.<\/p>\n\n<h3>Can I get an implant after dental sinusitis?<\/h3>\n<p>Often, implant planning is possible later, but infection and sinus conditions must first be stable. In some upper-jaw cases, sinus lift or bone assessment may be needed before implants.<\/p>\n\n<h3>When should I seek urgent care?<\/h3>\n<p>Seek urgent care if you have facial swelling, fever, severe pain, pus, difficulty opening your mouth, fluid or air passing between mouth and nose after extraction, or difficulty breathing or swallowing.<\/p>\n\n<h3>Can Gloss &amp; Floss diagnose dental sinusitis without CBCT?<\/h3>\n<p>We can perform clinical assessment and use dental X-rays or panoramic X-ray when needed.
