Living by the beach may feel like a dream come true, but it has its downsides, particularly for your teeth. Many people don’t realise that the environment we live in can directly influence oral health. Much like the rest of our bodies, our teeth are affected by our environment.
Our experienced dentists in Bournemouth, who regularly treat patients exposed to coastal conditions, explain how beach living can accelerate dental problems and what you can do to protect your smile.
Ocean Breeze Feels Great on Skin, not so Much on Teeth
Sea air is one of the biggest perksof living in a coastal town like Bournemouth. It’s refreshing and comforting. The South Coast airgenerally tends to be less polluted than the air in more congested areas of England. However, despitemore cleanliness, sea air contains high concentrations of salt particles, which can affect your teeth more than the air in non-coastal environments.
Salt in the air doesn’t directly damage teeth. However, it can increase the risk of having a dry mouth, according to dentists in Bournemouth. A dry mouth has reduced saliva production, which is a bad thing, as salivais the most powerful natural defence against tooth decay.
Saliva flushes out bacteria and plaque in the mouth, whichis what leads totooth decay. But when your mouth is dry,the enamel is not protected as usual,making your teeth moreprone to decay and infections.
Dry mouth can be a particular concern for those who lovespending time by the beach swimming, surfing,joggingor dog walking. Certain beach-centred professionals, like lifeguards, can also suffer from dry mouth caused by salty air.
It’simportant to note thatthe level of exposure is important here. Just taking a walk on the beachwon’tlead to serious dry mouth. However, frequent exposure to seawater when you spend prolonged periods near the ocean can cause chronic dry mouth.
So, if you spendlong hours outdoors near the beach, make sure you are hydrating yourself properly.The risk for your enamel becoming vulnerable is higher in coastal areas. Therefore,it’sbestto book aroutine general dentistry check-up to avoid potential oral health problems in the future.
High Humidity Can Increase the Risk of Gum Irritation and Discomfort
Coastal regions have high humidity levels, whichdoesn’tgo unnoticed by your gums. Humidity increases the moisture in the atmosphere, which can encourage bacterial growth in the mouth, making your gums more prone to tenderness andpossibly inflammation.
There’s scientific evidence for high humidity, paired withlow temperatures, can worsen gum health.One study found that,when the air is more humid, it can change the way bacteria behave in the mouth andhowyourgum tissues respond tothem.In simple terms, the study shows that the climate around us can play a role in oral health,particularly if that climate is humid.
Partly, thebadeffecton gumsisexacerbatedby the dry mouth effect explained above. Dry mouth cancause bacteria to attack your gums just as your teeth. For most people, thisisn’ta problem with proper oral care. However, if plaque managementisn’tadequate,coastal humidity could increase your risk of gum disease. If you already have gum disease, living in a coastal town could increase your risk of developing periodontal disease (a worsened form of gum disease that can cause tooth loss)
There’s Solution! What Dentists in Bournemouth Recommend
You don’t have to give up living a cosy beach life to save your teeth and gums. The bad effects of coastal living on oral health can be successfully managed with preventive dentistry treatments.
As your dentist may have told you from childhood,the first-line protection against tooth problems anywhere is proper brushing and flossing on a daily basis. Here are several other tips from our dentists:
- Stay hydrated, especially after outdoor activities near the beach.
- Always use a fluoride-based toothpaste to brush.
- Occasionally use an alcohol-free mouthwash to protect gums.
- Don't brush right after eating.
- Try to limit consuming sugary food.
- Keep up with regular dental check-ups, even if you don't feel like your teeth are bad.
Routine checkups assess teeth and gum problems you may not otherwise notice when brushing and flossing.Visiting a dentist at least once every 6 months is one of the best ways to catch gum disease before it becomes difficult to manage.
