Why Do My Teeth Look Darker as I Age?

Have you ever looked in the mirror and wondered why your smile isn’t quite as bright as it used to be? You’re not alone—many people notice their teeth looking darker or more yellow over time. It’s a common question we hear at Kingston Beach Dental, so let’s explore the facts behind age-related tooth discolouration and what you can do about it.

What’s Happening?

As we get older, it’s perfectly normal for teeth to change colour. The outer layer of your teeth, called enamel, naturally wears down over time, revealing more of the yellowish dentine beneath. Everyday habits—like drinking coffee, tea, red wine, or eating certain foods—can also leave surface stains that add up year after year.

What Contributes to Darkening Teeth?

●      Thinning Enamel: With age, enamel gradually becomes thinner due to brushing, acidic foods, and normal wear, making teeth look more yellow or grey.

●      Stains from Foods and Drinks: Beverages like coffee, tea, and red wine, along with foods such as berries and sauces, can cause surface stains that accumulate over time.

●      Natural Dentine Exposure: As enamel thins, the dentine (the inner part of your tooth, which is naturally darker) becomes more visible.

●      Lifestyle Habits: Smoking or using tobacco or vaping products can significantly darken teeth.

●      Medications and Health Conditions: Some medications, childhood illnesses, or even trauma to the teeth can affect their colour.

●      Changes in Oral Care: As we age, gums may recede, exposing more tooth surface and making stains or discolouration more noticeable.

What Can Help?

●      Professional Cleaning: Regular dental cleans can remove surface stains and brighten your smile. We recommend 6-monthly checkups as part of your ongoing oral health care.

●      At-Home Whitening: Over-the-counter whitening products may help with mild staining, but always check with your dentist first.

●      Professional Whitening: For more noticeable results, talk to your dentist about safe, professional whitening options tailored to you.

●      Daily Oral Care: Brushing with fluoride toothpaste and flossing daily helps reduce stain build-up and keeps teeth healthy.
