In a Gaza survey, those reporting severe oral pain rose from 6.5% to 73.8%

A cross-sectional study published in BMC Oral Health on 27 July measured a corner of the Gaza health crisis that rarely appears in situation reports: what happened to people's teeth and gums, and to their ability to get dental care, during the 2023–2024 war [s1].

The finding is a steep, across-the-board deterioration. But the study's design shapes what that finding can and cannot support, and the design is worth stating plainly first.

What was done

The researchers surveyed 599 Gaza residents using a structured, self-developed 34-item online questionnaire [s1]. Participants reported their oral-health conditions and behaviours for two periods: before October 2023, and during the war [s1]. Because both sets of answers came from the same people at one sitting, the "before" figures are recalled rather than recorded at the time — a limitation the reader should carry through every number below.

The numbers

The study reports significant deterioration across all 12 assessed domains, with the change reaching statistical significance in every one — p below 0.001 for 11 of the variables and 0.013 for the remaining one [s1]. The most striking shifts:

• Severe oral pain: the proportion reporting it rose from 6.5% before the war to 73.8% during it, while those reporting no pain fell from 25.5% to 2.0% [s1].
• Self-rated dental status: favourable ratings (excellent or good) fell from 85.3% to 9.7%, and the share reporting healthy gums fell from 88.1% to 12.4% [s1].
• Hygiene behaviour: twice-daily tooth brushing fell from 77.5% to 9.5%, and complete cessation of brushing rose from 0.8% to 38.4% [s1].
• Access: unmet dental-care needs rose from 11.7% to 92.7%, with insecurity and the absence of dental services named as the main barriers [s1].

The authors also report that stress-related oral habits — such as clenching and grinding — increased markedly, that 86.0% of participants described dependence on canned foods, and that 95.5% perceived their oral health to have worsened since the war began [s1].

Those two findings are worth pausing on because they point to mechanisms beyond the obvious loss of dental services. A diet forced onto canned and shelf-stable food is typically higher in the sugars and refined carbohydrates that feed tooth decay, and lower in the fresh foods that do not — a dietary shift that damages teeth independently of whether anyone can brush. Chronic stress, meanwhile, drives clenching and grinding that crack and wear teeth. Layered on top of the collapse in brushing and the near-total loss of access to care, they describe several routes to the same deterioration operating at once, which is consistent with the finding that every measured domain moved together [s1].

What it means, and what it doesn't

Oral health is not a headline concern in a humanitarian emergency, and that is partly the study's point: it argues that dental care is a neglected dimension of crisis response that is easy to defer and hard to restore [s1]. Untreated dental infection is painful, interferes with eating, and can progress to serious systemic infection — consequences that compound the nutritional and infectious pressures documented elsewhere in Gaza.

The interpretation has to respect the method. This is self-report, collected online, from 599 people who had the connectivity and inclination to complete a questionnaire — not a clinical examination of a representative sample. Recall bias tends to sharpen a before-and-after contrast, and the magnitude of some shifts, such as brushing cessation rising from under 1% to nearly 40%, should be read as the direction and scale participants reported rather than a clinically measured rate. The authors analysed the paired responses with Bowker's and McNemar's tests, which are appropriate for this kind of before-and-after categorical data, but no statistical test corrects for the design's underlying reliance on memory [s1].

Why it is still worth reporting

Within those limits, the study does something the situation reports do not: it puts numbers on a form of suffering that is otherwise invisible in the aggregate casualty and disease figures. The consistency of the deterioration — every one of 12 domains moving the same way — is harder to attribute to noise than any single figure [s1]. The authors' conclusion is a service point rather than a political one: that essential dental care belongs in emergency health responses and in post-conflict reconstruction planning [s1].
