Summer Smiles and Sun Safety
Jul 02 , 2025
When we think of summer sun safety, our minds often go straight to sunscreen and skin care—but what about your mouth? The lips and oral tissues are just as vulnerable to UV damage as your skin, yet they’re often overlooked. July is UV Safety Month, making it the perfect time to shed light on this important but under-discussed area of oral health.
The Overlooked Risk of Lip Sunburn
Your lips, particularly the lower lip, are regularly exposed to sunlight and lack the melanin that protects other parts of your skin. As a result, they are especially prone to sunburn and long-term UV damage. Repeated exposure without protection increases the risk of developing actinic cheilitis, a condition that can lead to lip cancer.
Quick tip: Always use a lip balm with an SPF of 30 or higher. Reapply it every two hours, especially after eating or drinking.
Oral Cancer and Sun Exposure
UV radiation is a known risk factor for lip and oral cancers. According to the Canadian Cancer Society, lip cancer falls under the broader category of oral cancer, which is increasingly diagnosed in people over the age of 45—but sun exposure from earlier years may contribute to its development. Lesions on the lips or inside the mouth that don’t heal within two weeks should be examined by a dentist immediately.
Signs of Sun Damage in the Mouth
It’s not just the skin or lips. Sun damage can affect the soft tissues inside your mouth as well. During your routine dental exams, we check for early signs of abnormal changes such as:
Persistent sores or ulcers
White or red patches on the soft tissues
Lumps or swelling in the gums or cheek lining
If caught early, these symptoms can be treated more effectively.
Hydration and Oral Health Go Hand in Hand
Dehydration is a common issue in hot summer months, especially when people spend more time outdoors. Reduced water intake and increased sweating can lead to dry mouth, which affects saliva production. Saliva is crucial for neutralizing acids, washing away food particles, and protecting teeth from decay.
Stay hydrated with water throughout the day. Skip sugary sodas or citrusy drinks that can wear down enamel, and opt for a refillable water bottle when you're on the go.
Protecting Your Smile All Summer Long
A few small changes to your summer routine can go a long way in protecting your oral health:
Use a wide-brimmed hat to shield your face and lips from the sun.
Keep sugar-free gum handy to stimulate saliva flow when your mouth feels dry.
Schedule a summer dental cleaning and oral cancer screening to stay proactive.
Pack SPF lip balm with your beach bag, hiking gear, or picnic supplies.
