People who suffer from regular headaches have been advised to see an emergency dentist, as the problem could be related to oral health.
The British Dental Health Foundation (BDHF) suggested that persistent headaches could be a result of temporo-mandibular joint (TMJ) disorder, which is caused by an imbalance when biting the jaws together.
Affecting one in seven people across the UK, the condition causes migraines due to increased pressure on nerves, muscles and blood vessels near the head.
Chief executive of the BDHF Dr Nigel Carter has urged individuals who are showing signs of the illness to seek attention from a dental expert.
He said: "Your dentist may be able to help you or may refer you to a specialist who deals with occlusal problems."
Colgate advises people living with TMJ disorder to eat a diet consisting of mainly soft foods, such as soup, scrambled eggs and fruit smoothies.
The organisation recommends that sufferers avoid yawning or singing often to prevent painful symptoms.
