What to eat (and avoid) for a healthier smile
Maintaining good oral health isn’t just about brushing and seeing your dentist – it also comes down to what you eat every day. The food and drink we consume plays a significant role in the health of our teeth and gums.
In this guide, we’ll explain the best food for better teeth, highlight food good for teeth, and flag up the most common bad food for teeth. You’ll also learn how your diet can help prevent common dental problems such as decay, gum disease, and enamel erosion.
At Hakimi Dental Clinic in Oldbury, our experienced team combines expert care with practical advice to help patients of all ages maintain strong, healthy smiles. Whether you’re coming in for a routine check-up or a visit to the dental hygienist, our focus is always on prevention first — and nutrition is part of that picture.
Why diet matters for oral health
Your teeth and gums need certain nutrients to stay strong and fight off problems like decay and infection. Just as poor diet can harm your general health, it can also lead to tooth erosion, cavities, or inflammation in the mouth.
A balanced diet filled with food that is healthy for your teeth can support enamel strength, saliva production, and healthy gum tissue — all of which are essential for keeping your smile in top shape.
The Oral Health Foundation states that some foods and drinks have surprising benefits for teeth, beyond just avoiding sugar.
Best food for better teeth
Here are some of the top choices when it comes to food good for teeth:
1. Cheese and dairy products
Cheese, milk, and plain yoghurt are rich in calcium and phosphates. These minerals help strengthen tooth enamel and may even help repair damage in its early stages. Cheese also helps balance the pH in your mouth, reducing the risk of decay.
2. Leafy greens and vegetables
Spinach, kale, broccoli and other leafy greens are full of calcium, folic acid and other vitamins that support healthy teeth and gums. Crunchy veg like carrots and celery also stimulate saliva and help clean the teeth naturally.
3. Apples and pears
Although apples contain sugar, they also contain fibre and water, and chewing them increases saliva production. This helps rinse away food particles and bacteria, making them a smart snack when brushing isn’t an option.
4. Nuts and seeds
Almonds, sesame seeds, and brazil nuts are good sources of calcium, magnesium and phosphorous – all crucial for enamel strength.
5. Sugar-free gum
Not a food, technically – but chewing sugar-free gum (especially with xylitol) helps increase saliva flow and neutralise acid in the mouth after meals.

Bad food for teeth to limit or avoid
Just as there are foods that protect your teeth, there are plenty that can do real damage. Here’s a list of bad food for teeth you’ll want to limit as much as possible:
1. Sugary snacks and sweets
Sweets, biscuits, cakes, and chocolate feed the bacteria that cause tooth decay. Sticky or chewy sweets are the worst offenders, as they cling to teeth for longer.
2. Fizzy drinks
Even sugar-free fizzy drinks contain acids that can wear away enamel over time. Regular consumption of soft drinks is one of the leading causes of enamel erosion.
3. Fruit juices and smoothies
While fruit is healthy, concentrated juices are acidic and high in sugar, which can harm teeth. If you do drink them, use a straw and rinse with water afterwards.
4. Crisps and starchy snacks
Foods like crisps break down into sugars and can get stuck in your teeth, especially in the back molars, where they may not be brushed away easily.
5. Alcohol
Alcohol, especially when consumed in excess, can dry out the mouth, reduce saliva flow, and lead to gum issues over time.

Food that is healthy for your teeth: daily tips
Building a tooth-friendly diet doesn’t have to be difficult. Here are some simple ways to include food that is healthy for your teeth in your daily routine:
- Start your day with dairy or oats: Greek yoghurt or porridge with seeds can give your teeth a calcium and fibre boost.
- Snack smart: Choose carrots, cucumber, celery or a handful of nuts.
- Drink plenty of water: It helps rinse away acids and bacteria.
- Eat cheese after meals: It can help reduce the acid impact of other foods.
- Limit snacking: Frequent eating increases the time your teeth are exposed to acids.
These changes, combined with regular dental check-ups and professional cleanings by our Oldbury dental hygienist, can help keep your mouth in excellent condition.
