Substance use disorders affect millions of people worldwide. They cut across every age group and background. Yet only one in eleven people globally who need support for substance use actually receive it. That gap is significant. It points to a real need to think differently about where these conversations can begin.

One answer may already be sitting in your local high street: the dental surgery.

The Dental Visit Most People Actually Keep

Almost 30 million Americans see a dentist each year but not a doctor. In the United Kingdom, most adults visit their dentist more frequently than their GP. More than a quarter have raised health concerns unrelated to their teeth during those appointments. This matters. Dental professionals have regular, face-to-face contact with people who might otherwise fall through the cracks of general healthcare.

Dentists observe the mouth closely, and the mouth reveals a great deal. Tobacco, alcohol, and other substances leave distinctive marks. Advanced tooth decay, gum disease, dry mouth, and oral infections are all common signs. In serious cases, oral cancer can develop. These are not incidental findings. A dentist often spots these warning signs before any other healthcare professional does, making dental screening for substance use a genuinely valuable first step.

Dental Screening for Substance Use: A Missed Opportunity

Despite this natural positioning, most dentists do not routinely screen for substance use. Research across North America, Europe, and the Middle East consistently shows that dentists feel underprepared to raise the subject. Many question whether it falls within their professional role. Others worry about disrupting the clinical relationship or making patients feel judged.

Stigma is part of the problem. Studies show that some dental providers hold subtle negative attitudes towards patients with substance use disorders. They sometimes view these conditions as a matter of personal failing rather than a health issue. Providers who think this way are far less likely to raise the subject with patients. That silence has real consequences.

Training is another significant gap. Screening, Brief Intervention and Referral to Treatment (SBIRT) is a well-established model that primary care settings use to identify and address substance use early. Dental education rarely includes it. Dental surgeries rarely apply it.

What Better Dental Screening Looks Like

Improving dental screening for substance use does not mean turning every appointment into a clinical interview. It starts with better training. Dentists who have prior knowledge of substance use issues are significantly more likely to screen patients. They are also more likely to see that screening as a natural part of their role.

Dental hygienists deserve a bigger part in this effort. They often see patients more regularly than dentists do. Brief conversations during routine preventive care visits are a natural fit for raising substance use concerns without disruption.

Stronger links between dental and medical services would also help. Integrated practice models with clear referral pathways make it far easier for a dentist to connect a patient with the right support quickly. Telehealth tools that allow dental and medical clinicians to share information can help too. When a dentist spots signs of a substance use disorder, the next step should not be complicated.

Anti-stigma work matters across all of this. When dental teams hear personal stories from people affected by substance use disorders, their attitudes shift in more meaningful ways than any lecture achieves. International campaigns that promote non-stigmatising language help build a culture of empathy across the profession.

The Financial Reality

Money matters here and we cannot ignore it. Most dentists say they would offer substance use screening if someone paid them fairly to do it. In many countries, dental insurers support the idea of medical screenings in principle. In practice, they resist paying for them. They raise concerns about billing code overuse and the cost impact on patients’ annual dental benefit.

In the United States, some insurers argue that oral cancer checks and smoking cessation advice are already standard care and need no separate reimbursement. That argument is circular. It credits dentists with doing work they are rarely trained or resourced to do, then refuses to fund the change that would make it happen.

The evidence directly linking dental screening for substance use to better health outcomes is still growing. More implementation research is needed. But the logic is clear. Patients with substance use disorders present more often to dental surgeries in distress. They have more advanced oral disease. They benefit from early connection to support. The dental setting offers something rare: a consistent point of contact with people who services often do not reach.

A Broader Role for Dental Professionals

The World Health Organisation calls for oral health to integrate into primary care and universal health coverage. That goal requires the dental profession to see itself as part of a wider healthcare team, not a specialist silo.

Dental screening for substance use disorders is one concrete expression of that shift. It is not about dentists becoming addiction counsellors. It is about recognising that a brief conversation in the dental chair, or a well-placed referral after spotting early warning signs, can change the course of someone’s life. Around 30 million people in the US alone already walk through the dentist’s door each year but skip the GP. The opportunity is there.

The patients are already coming through the door. The question is what happens next.
