Key dental hygiene tips for seafarers

Safety June 2023

Published on 20 Jun 2023

As seafarers spend long periods of time onboard ships, they are unable to visit a doctor for check-ups when required. Dental care is a common issue that the crew faces while at sea. In a worst-case scenario, dental problems require urgent medical treatment or even the repatriation of seafarers.

When a dental issue arises, it usually affects seafarers’ work productivity and performance, while it also influences their concentration and leads to a safety risk.

What is really hiding behind dental problems?

The main causes of dental problems are:

  • Tendency to consume highly caffeinated, energy and sugary drinks due to the long working hours onboard
  • Unhealthy and untimely snacking
  • High levels of nicotine inhalation

Seafarers must pay attention to their dental health and take care of their teeth to avoid periodontal (gum) disease.

The pain relief medicines onboard are a temporary solution as they don’t fix the overall problem. A dental problem can worsen if its symptoms are not observed early.

Specifically, the symptoms include:

  • Persistent bad breath
  • Red or swollen gums
  • Bleeding or tender gums
  • Painful chewing
  • Loose or sensitive teeth

As the dental care systems vary from port to port, the quality of care may also differ from region to region.

Key practices for healthy teeth

Seafarers must consider the importance of maintaining a good oral hygiene and follow below-mentioned practices:

  • Take regular dental check-ups, especially before embarkation or long voyages
  • Brush teeth properly for approximately two minutes, at least twice a day
  • Make circular and gentle movements during brushing each tooth
  • Change toothbrush every three to four months, when bristles begin to fray
  • Properly rinse mouth after brushing
  • Floss teeth daily after a meal
  • Make sure that toothbrush’s bristles cover teeth as well as gums
  • Choose a brush as per individual needs. A soft-bristled brush to remove plaque and debris from teeth or a powered toothbrush for teeth cleaning
  • Brush tongue to remove bacteria and freshen breath
  • Use a mouthwash when required to control plaque bacteria and avoid bad breath

Always remember that personal hygiene can prevent possible toothaches, which can negatively affect your concentration, sleeping, eating etc.
