Mouth cancer is a major health problem in Scotland, a new campaign has warned.
The country has the highest incidence of the disease anywhere in the UK.
Now dental staff and students at Dundee University are raising awareness of the condition to alert more people to the early warning signs.
Smoking, drinking excessive amounts of alcohol, poor diet and oral hygiene can all put people at risk.
The British Dental Health Foundation estimates that over the next decade around 60,000 people in the UK will be diagnosed with mouth cancer and, without early detection, an estimated 30,000 will die.
In Scotland there are 11.9 cases of the disease per 100,000 people, compared with 8.1 cases per 100,000 in England and 9.4 cases per 100,000 in Wales. To coincide with Mouth Cancer Awareness Week, the Dundee staff and students will be giving the public oral health advice.
Dr Simon Shepherd, clinical lecturer at the university's dental school, said: "Early detection and treatment of the disease is vital. In addition, we need to be raising the awareness of the risk factors and what people can do to help prevent the disease.
"People can reduce the risk of mouth cancer by limiting the amount of alcohol they consume, adopting a healthier diet and not smoking. Smoking and alcohol are the two main risk factors for the disease, which is why it is so important to make young people aware of the risks.
"Mouth cancer can affect people of all ages. Historically, oral cancer mainly affected older age groups but now one in 10 cases is found in the under-45 age group."
Regular dental check-ups are said to be the best way of detecting the disease early. Symptoms of mouth cancer can include ulcers that do not heal within two weeks, red or white in the mouth, unusual lumps or swellings in the mouth and numbness of the tongue or other parts of the mouth.
