Foods That Help (or Hurt) Your Teeth: A Guide to Smile-Friendly Eating

What you eat doesn’t just affect your overall health—it plays a significant role in your oral health too. At Bay House Dental in Cardiff, we’re passionate about helping you maintain a healthy smile, and diet is a key factor. Knowing which foods are good for your teeth—and which ones to limit—can make all the difference in preserving your oral health.
 

Smile-Friendly Foods: What to Include in Your Diet

Some foods actively contribute to stronger, healthier teeth. Incorporating these into your diet can help protect your smile:
  • Dairy Products: Milk, cheese, and yoghurt are rich in calcium and phosphorus, essential for strengthening tooth enamel and supporting healthy bones. Cheese also increases saliva production, which helps neutralise acid in the mouth.
  • Crunchy Fruits and Vegetables: Apples, carrots, and celery are nature’s toothbrushes! Their crunchy texture stimulates gums, increases saliva, and helps scrub away plaque.
  • Leafy Greens: Spinach, kale, and other leafy greens are packed with vitamins and minerals like calcium and folic acid, promoting healthy teeth and gums.
  • Nuts and Seeds: Almonds, walnuts, and sesame seeds are not only low in sugar but also high in essential nutrients like calcium and phosphorus.
  • Green Tea: Rich in antioxidants, green tea helps reduce inflammation and fights bacteria in the mouth, contributing to better gum health.
   

Foods That Can Hurt Your Teeth

While some foods are beneficial, others can harm your teeth if consumed frequently or without proper care. Be mindful of the following:
  • Sugary Snacks and Drinks: Sweets, fizzy drinks, and fruit juices are loaded with sugar, which feeds bacteria in the mouth and leads to tooth decay.
  • Sticky Foods: Dried fruits, toffees, and caramels tend to stick to teeth, making it harder to clean them and increasing the risk of cavities.
  • Acidic Foods and Drinks: Citrus fruits, vinegar-based dressings, and fizzy drinks (even sugar-free ones) can erode enamel over time, making teeth more susceptible to decay.
  • Starchy Foods: White bread, crisps, and other starchy snacks can break down into sugar, contributing to plaque build-up.
  • Alcohol: Excessive alcohol consumption can dry out your mouth, reducing saliva production and increasing the risk of cavities and gum disease.
   

Keeping Your Teeth Healthy
Enjoying your favourite foods in moderation, combined with good dental hygiene practices, can help minimise their impact on your oral health. After consuming sugary or acidic foods, rinse your mouth with water and wait 60 minutes before brushing to avoid damaging softened enamel.
