- People with a learning disability are more likely to have gum disease, untreated decay and missing teeth. Mencap says the right support and adjustments can keep teeth healthy for a long time.
- Pain may not be put into words. A change in behaviour can be the only sign, so check the mouth and see a dentist.
- Mencap says dental practices have a legal duty to make reasonable adjustments, such as a longer or quieter appointment, a practice visit, easy read information or seeing the same dentist.
- If a general practice cannot help even with adjustments, ask about special care or community dental services. Some people need sedation or a general anaesthetic.
- Adults are presumed able to make their own decisions. If a person cannot decide about treatment, the NHS says the decision must be made in their best interests.
The NHS describes a learning disability as something that affects the way a person learns new things throughout their life, and says it is different for everyone. GOV.UK guidance notes it is not the same as a condition such as dyslexia. "Learning disability" is the UK term. Australian government sources say intellectual disability, and US sources say intellectual and developmental disabilities (the Medicaid and CHIP Payment and Access Commission, MACPAC) or developmental disabilities (the National Institute of Dental and Craniofacial Research, NIDCR). We follow each source's wording. See also caring for someone else's teeth and autism and dental care.
Why are mouth problems more common?
Public Health England guidance on GOV.UK (first published 2019) says research consistently shows more gum disease, plaque and missing teeth, and poorer access to dental care. Evidence on tooth decay is mixed, it says, but untreated decay is consistently higher, and decay is more likely to be treated by taking the tooth out than by filling it. NHS England says children and young people with a learning disability, autism or both have higher levels of untreated tooth decay. Mencap says this is one of the most common health problems for people with a learning disability, particularly people with Down syndrome.
Risk factors listed in the GOV.UK guidance include:
- frequent sugar
- medicines that reduce saliva or inflame the gums (see dry mouth and medicines that affect your mouth)
- gastro-oesophageal reflux (see acid reflux and teeth)
- difficulty holding a brush, sensitivity to touch, or not understanding why brushing matters
- relying on others for mouth care and dental visits
NIDCR adds that seizures can chip teeth and that crowded or unusually shaped teeth are harder to clean. The NDIS Quality and Safeguards Commission (Australia) says people on soft diets are at extra risk from food left in the mouth.
Why can problems be missed?
Mencap explains that poor oral hygiene can cause significant pain before any damage is visible, and some people struggle to say that something hurts, so treatment can come too late. The GOV.UK guidance says untreated pain often shows as behaviour described as challenging, and warns about diagnostic overshadowing: signs of ill health being put down to the person's disability instead of being investigated. In one case it describes, a young man's increased self-injury was caused by a dental abscess. The NDIS Commission says pain may show as irritation or distress. For other signs of pain, see caring for someone else's teeth.
Daily mouth care and support
Mencap says most people with a learning disability are likely to need some extra support. The NDIS Commission's practice alert asks support workers to:
- ask the person whether they want help, and make sure they have a toothbrush, fluoride toothpaste and any cleaning aids the dental team suggests
- support brushing with fluoride toothpaste twice a day, cleaning between the teeth, cleaning dentures, clearing food from the mouth after eating, drinking enough water and cutting down on sugar
- include mouth care in the person's support plan
- arrange check-ups at least every 12 months, and a dental visit sooner if gums bleed or become puffy, lumpy or inflamed, or the person shows mouth pain
It says an occupational therapist can help with handling a toothbrush, and a speech pathologist can help if someone has trouble chewing, swallowing or clearing food from the mouth.
Reasonable adjustments and preparing for visits
In the UK, Mencap says reasonable adjustments are a legal right under the Equality Act 2010. The GOV.UK guidance adds that services should plan them in advance. Examples Mencap gives:
- a longer appointment, or one at a quieter time of day
- things explained more slowly or clearly, or in easy read
- a practice visit beforehand to meet the staff
- someone coming into the room with you
- seeing the same dentist each time
Call ahead so the practice can prepare. The GOV.UK guidance also lists social stories, picture cards, the first appointment of the day, waiting outside until the dentist is ready, and desensitisation: gradually introducing the person, step by step, to what they fear. In Scotland, NHS inform suggests a hospital passport: a document saying how the person communicates, their sensory needs, and how to tell when they are in pain.
In Australia, the NDIS Commission suggests social stories, asking for a longer appointment, bringing a list of medical conditions and medicines, and helping the person use their preferred way of communicating. See also dental anxiety.
Special care and community dental services
UK
- The NHS says people with additional needs should be able to get NHS care from a general dental practice, and may be referred to Special Care Dentistry for specialised treatment.
- The GOV.UK guidance describes community dental services in England for people who find high-street practices difficult, including people with learning disabilities. A referral from a medical or dental professional is often needed, criteria vary locally, and NHS charges apply there too unless the person is exempt. See dental costs and help.
Australia
- The Australian Dental Association says specialists in special needs dentistry treat people with intellectual disability. The NDIS Commission says a referral may be needed if other strategies do not work.
- In Victoria, people registered with disability services who have a letter from their case manager or a special developmental school get priority access to public dental care.
- In Western Australia, the government Special Needs Dental Clinic sees people aged 16 and over with a disability who are unlikely to tolerate mainstream treatment (among other criteria), free of charge, under general anaesthetic if needed.
United States
NIDCR says most people with mild or moderate developmental disabilities can be treated in a general dental practice. MACPAC says adult Medicaid dental coverage varies by state, from comprehensive to emergency-only to none, and some states cover extra services for adults with intellectual and developmental disabilities.
Sedation and general anaesthetic
Mencap says some people cannot cope even with adjustments, and the dentist may suggest sedation or a general anaesthetic. The GOV.UK guidance says other tests, such as blood tests, can sometimes be done during the same general anaesthetic. See dental sedation.
Consent and capacity
The NHS explains that all adults are presumed able to decide about their own treatment unless there is significant evidence otherwise. Capacity means being able to understand, remember and use the information, and communicate a decision by any means. It is assessed when a decision is needed, and a person may be able to make some decisions but not others. If someone lacks capacity and has not appointed anyone to decide for them, professionals decide in their best interests, involving the person as much as possible. If there is no suitable family member or friend, an independent mental capacity advocate must be consulted.
Good explanation matters. The GOV.UK guidance describes a man a dentist felt lacked capacity; at another hospital a dental surgeon took time to explain, and he was judged able to consent to treatment in small steps under local anaesthetic. The NDIS Commission encourages supported decision-making.
Annual health checks
- England: the NHS says anyone aged 14 or over on their GP's learning disability register can have a free annual health check, and you can ask to join the register. The NHS list of what happens at the check does not mention teeth, so raise any mouth worries.
- Scotland: NHS inform says checks are for people aged 16 and over, and your information may be shared with your dentist.
- Australia: Medicare supports a yearly health assessment for people with intellectual disability. Medicare rules say it must include checking dental health, where relevant.
- Gums that bleed or look puffy, lumpy or inflamed, or signs of mouth pain (NDIS Commission).
- New or increased distress, irritation or self-injury, which may be a sign of pain (GOV.UK guidance, NDIS Commission).
- It has been more than a year since the last check-up (NDIS Commission).
- A swollen face or jaw, severe toothache or a high temperature may be a dental abscess. In the UK, the NHS says to ask for an urgent dental appointment or contact NHS 111.
- Call 999 or go to A&E (or your local emergency number) if the person is finding it hard to breathe, speak or swallow, or has a lot of swelling in the mouth (NHS).
Frequently asked questions
Can I ask the dentist for a longer appointment?
Yes. Mencap and the GOV.UK guidance both list it as a reasonable adjustment. Ask when you book.
What if the person will not let anyone look in their mouth?
Tell the practice what is difficult. MACPAC says desensitisation often takes place over several visits. If that does not work, ask about referral to special care or community services.
Does the person have to go to a special service?
No. The NHS says people with additional needs should be able to get care from a general practice.
