Being bothered about Billy’s oral health

David Shiers is a carer for his daughter with severe mental illness.

Gordon Johnston is a person with lived experience of severe mental illness.

We all know that the life expectancy of people with severe mental illness (SMI) is reduced by 15–20 years compared to the general population. The higher mortality rates are driven by physical health comorbidities including heart disease, obesity, and diabetes, worsened by lifestyle behaviours and metabolic side-effects of antipsychotic medication, as well as reduced access to adequate health care.1

Moreover, the mortality gap is widening the trend, mainly due to cardiovascular disease (CVD), now the single biggest cause of premature death in people with SMI.2 In her 2012 James Mackenzie Lecture to the Royal College of General Practitioners (RCGP) annual general meeting, the late Helen Lester encouraged GPs to make people with serious mental illness their core business by not just screening but also intervening.3

What is less well known is that people with SMI also experience serious inequalities in oral health, with high rates of tooth decay, gum disease, and tooth loss (see Box 1). This can affect daily life including with basic activities such as eating and speaking.

Poor dentition can impact on a person’s confidence and self-esteem; it can interfere with relationships or the ability to get and keep a job. This, in turn, impacts on mental health and a vicious cycle ensues. Poor oral health can also increase risks associated with other health conditions such as diabetes and heart disease (which are already increased in this population).4 This means that people experiencing SMI may be dealing with multiple health problems at the same time that are exacerbated by poor oral health.5

Box 1. Oral healthcare factors associated with people with severe mental illness compared to the general population
  1. More likely to have decayed, missing, and filled teeth.6
  2. More likely to experience gum and supporting bone problems.5
  3. Less likely to access dental services.7
  4. At risk of acute non-psychiatric hospital admission due to tooth decay.8

The Right to Smile

The Right to Smile consensus statement9 arose from the Oral Health and Primary Care special interest groups established by the Closing the Gap Network, a UK Research and Innovation-funded initiative to develop a mental health network exploring ways to reduce the health gap faced by people experiencing SMI.10

Our Oral Health special interest group comprises people with lived experience, carers, mental health practitioners, dental professionals, researchers, and policymakers. Our ambition is to reduce the inequalities in oral health faced by people experiencing SMI. The Right to Smile consensus believes that tackling this inequality is overdue and deserves urgent attention from services across primary, specialist, and social care, researchers, and policymakers.

The Right to Smile consensus statement has been endorsed by several important bodies including the Royal College of Psychiatrists, Psychosis Research Unit, Office of the Chief Dental Officer of England, World Dental Federation (FDI), a number of voluntary sector organisations, and supported by collaborating universities. We are hoping that the RCGP will endorse this important piece of work and encourage primary care to consider oral health in patients with SMI registered with their practices.

What is/should be the role of primary care?

We outline where opportunistic advice can be given to people with SMI, about oral health, in primary care (see Box 2). We can make a difference to this vulnerable group of patients — improving their quality of life and reducing health inequalities — the core business of general practice.

Box 2. Opportunities to discuss oral health in primary care
  1. As a critical opportunity for prevention, 70% of people will have been signposted to dental care and/or preventive dental advice6 within 6 months of first receiving a diagnosis and medication for a SMI.
  2. ‘Making every contact count’11 reminds us to consider oral health whenever we consult with our patients with SMI.
  3. In the annual physical health check in primary care,12 health promotion advice about healthy eating, tobacco, and substance use should also prompt discussion and support around oral health, including signposting to a dental service or online preventative advice for those not attending regular dental check-ups.
  4. Carers should be made aware of the importance of oral health for those they support, and given advice and information on how they can encourage good oral hygiene.
