The Sun and Your Smile:

How Summer Affects Oral Cancer Risk

Summer in Redondo Beach means long days outdoors, whether at the beach, hiking trails, or backyard barbecues. While sunscreen is a staple for skin protection, many people overlook how sun exposure impacts oral health. Understanding the risks and prevention strategies can help you enjoy the season safely.

UV Exposure and Lip Health

The lips are particularly vulnerable to sun damage because:

They lack melanin, which provides natural UV protection
The skin is thinner than on other parts of the body
Many people forget to apply SPF to their lips

Prolonged sun exposure without protection increases the risk of:

Dry, cracked lips
Cold sore flare-ups
Long-term damage, including precancerous changes

Choosing the Right Lip Protection

Not all lip balms offer sufficient defense. Look for:

Broad-Spectrum SPF 30 or Higher – Protects against UVA and UVB rays
Moisturizing Ingredients – Beeswax, shea butter, or coconut oil prevent chapping
Avoid Shiny or Glossy Balms – These can reflect and intensify UV rays

Reapply every two hours, especially after eating, drinking, or swimming.

Recognizing Early Warning Signs

Oral cancer can develop on the lips, tongue, cheeks, or throat. Early detection is critical, so be aware of:

Sores that don’t heal within two weeks
Red or white patches in the mouth
Unexplained numbness or pain
Difficulty swallowing or persistent hoarseness

The Importance of Oral Cancer Screenings

Routine dental checkups include oral cancer screenings, where dentists examine your mouth for abnormalities. Since early-stage oral cancer often has no pain or obvious symptoms, these screenings are vital for catching issues before they progress.

Sun-Smart Habits for Oral Health

Beyond lip balm, consider these protective measures:

Wear a wide-brimmed hat to shade your face
Seek shade during peak sun hours (10 AM – 4 PM)
Stay hydrated to prevent dry mouth, which increases vulnerability to irritation

Enjoying summer safely means protecting every part of your body—including your smile. By incorporating sun-safe habits and staying proactive with dental visits, you can reduce risks while making the most of the season. If it’s been a while since your last oral cancer screening, now is the perfect time to schedule an appointment.
