Which food strengthens our dental health? 

When we think of healthy eating, most of us probably have the goal of supporting our cardiovascular system, avoiding being overweight or underweight and strengthening our gut. But did you know that a healthy diet can also help to keep our teeth and gums healthy? By making the right food choices, for example, you can reduce your risk of gingivitis and periodontitis or provide your teeth with calcium and phosphate in a targeted manner - which strengthens tooth enamel. And you can also keep caries bacteria at bay very effectively with the right diet. 

Let's take a look together at how all this works, which foods your teeth love - and which you'd be better off staying away from. 

These foods are good for gums and teeth

We all know what is permanently damaging to our teeth: sugar and acids. You'll find out more about this later.  But which foods are good for them? Here you will find an overview of tooth-friendly foods that you can enjoy without worrying: 

Foods containing calcium

Did you know that almost 100 per cent of the calcium in our body is contained in bones and teeth? There is a reason for this: calcium builds bones and teeth and keeps them stable. It is therefore important that we supply our body with calcium accordingly. This works wonderfully with certain foods. These include milk and dairy products such as cheese and yoghurt: 

  • Green vegetables such as broccoli, kale and rocket
  • Mineral water
  • some nuts such as hazelnuts and Brazil nuts
  • Phosphorus-containing foods

Speaking of calcium, we need the mineral phosphorus to be able to absorb it in our bodies and thus strengthen our bones and teeth. It is found in meat, fish, eggs, milk, wholemeal products and protein-rich foods, for example. When you eat these foods, you are therefore always consuming a portion of phosphorus. 

Fluoride-containing foods

Fluoride protects against tooth decay and strengthens tooth enamel. With fluoride toothpastes, we can achieve a localised protective effect directly at the site of action - i.e. the tooth. However, we can also strengthen our body from the outside. We can do this with the following foods:

  • Iodised table salt
  • Sea fish (sardines)
  • Black tea
  • Cereals
  • Meat 
  • Mineral and drinking water 

Good to know: 

With Enzycal 1450 ppm Fluoride toothpaste, you provide your teeth with optimum fluoride and thus protect them against tooth decay. Three natural enzymes additionally stimulate saliva production, which is also essential for protection against tooth decay. 

Wholemeal

Fancy a natural "toothbrush"? Then try wholemeal products more often! The rough surface of coarsely ground grains actually has a toothbrush effect. As you chew, the healthy grains automatically remove soft plaque from your teeth. Speaking of chewing: Wholemeal clearly requires more effort from our jaws than white flour products. And this intensive chewing ensures a greater flow of saliva, which in turn helps to clean our teeth. Our saliva also has a protective effect: it can reduce our risk of tooth decay by neutralising harmful acids in our mouth. 

Raw food

Raw food has the same positive effect on our teeth. Just nibbling on a crunchy carrot or a piece of kohlrabi helps to remove plaque. And because we also need a little more strength to crunch raw food in our mouths, more saliva is formed, which helps to neutralise caries bacteria. By the way, there's another little bonus: chewing raw food is like a massage for our gums. They are better supplied with blood. 

Green tea 

Drinking green tea protects your teeth from tooth decay. This is because it contains caries-inhibiting polyphenols. And so-called catechins! These help to kill bacteria. There are also active plant substances that neutralise the bacteria that cause bad breath. By the way: Black tea also has a similar effect - but green tea tops it!

Good to know: 

Of course, we should brush our teeth even after the healthiest meals. But of course we don't always have a toothbrush to hand. Black is White chewing gum is a tooth-healthy alternative for on the go. It reliably removes plaque from the teeth and also provides gentle whitening. 

Which vitamins benefit our teeth? 

Vitamins are good for the whole body, but some of them are especially good for our teeth and gums. Here you can find out which ones they are and what they are made of: 

Vitamin A

This vitamin helps us to have healthy oral mucosa. It is found, for example, in orange-coloured fruit and vegetables such as pumpkin, carrots and peppers, as well as spinach and tomatoes. 

Vitamin C

We all know vitamin C as an immune system booster. And this also indirectly helps us to maintain good oral health. Because if we are better able to fight off bacteria, gum disease is less likely to develop. At the same time, vitamin C is a building block of the dentin. It strengthens collagen formation in the gums. You can consume vitamin C by including citrus fruits, peppers, redcurrants, potatoes, spinach or parsley in your diet, for example. 

Vitamin D

Fatty fish, eggs, mushrooms and wholemeal cereals contain vitamin D. It plays an important role in bone and tooth formation. However, it is important to know that the majority of vitamin D is produced through the skin. We therefore need a certain amount of sunlight. In summer, ten minutes of sunshine is enough for people with light skin pigmentation. People with darker skin pigmentation should spend 20 to 60 minutes in the sun, as recommended by the Swiss Federal Office of Public Health FOPH. However, it is advisable to spend more time in the sun in the morning or afternoon and to avoid the strong rays at midday so as not to increase the risk of skin cancer. 

Sensitive teeth due to vitamin deficiency - can this happen? 

Yes, if we don't take enough of the vitamins mentioned above, our gums and teeth can suffer. Here we explain the connection: 

 

Vitamin D deficiency

Insufficient vitamin D significantly increases the risk of tooth decay, even in children during the growth phase. This also applies to adults with a long-term deficiency. This is because too little vitamin D disrupts the mineralisation of the teeth - they are then less stable and more susceptible to damaging acids. This can also lead to yellow discolouration of the teeth. 

 

Vitamin A deficiency

If our body gets too little vitamin A, our mouth can become too dry. And this in turn is unfortunately the best basis for caries bacteria to multiply. Vitamin A is also said to strengthen the immune system, which has the positive effect of reducing or eliminating gum inflammation. 

 

Vitamin C deficiency

Vitamin C is a precious commodity for our body. We can only absorb it through food and it cannot be stored. If we have too little of it in our body, this can also have an effect on our teeth and make itself felt through bleeding gums, for example. A lack of vitamin C can also be the cause of periodontitis.

These foods are harmful to our teeth

It's actually relatively simple: foods that are not good for our overall health are generally also bad for our teeth. Products that contain short-chain, fermentable carbohydrates such as sugar are at the forefront of this. We all know that sugar is one of the biggest enemies of our dental health. Here is an overview of foods that you should avoid or only rarely include in your diet. 

Pasta and sweets

All the treats at the bakery or in the confectionery section of the supermarket look incredibly tempting. But they contain carbohydrates - starch and sugar to be precise - which are really bad for our teeth. Unfortunately, this also includes everyday foods such as bread and pasta. Do you want to give them up completely? That's probably difficult for most of us! But if you reach for the wholemeal varieties more often, you can do a lot for your teeth and gums. As you've already read above, chewing more intensively with these products helps to stimulate your saliva flow, which has a very positive effect on your tooth enamel and keeps caries bacteria at bay. And when you get a sweet tooth? Then you may not always be able to hold out, as everyone will understand. But then it's better not to indulge your "sweet tooth" all day long, but to reach for your favourite chocolate just once a day and enjoy a big bite. This way, there is only a one-off contact between the sugar and your teeth and not a permanent one. 

Salty snacks 

No chocolate? No ice cream? No candy floss? Okay, then bring on the pretzel sticks and crisps! It would be nice if it were that easy. But unfortunately, these snacks also contain short-chain carbohydrates, which promote the formation of tooth decay. Crisps even have another disadvantage: they stick to the chewing surfaces and can do their job perfectly. Namely cause tooth decay. After eating crisps, it is therefore even more important to brush your teeth thoroughly afterwards!

After eating crisps, it is therefore even more important to brush your teeth thoroughly afterwards! 

Good to know: 

Not only do crisps and the like stick wonderfully firmly to our chewing surfaces - they also cheat their way unnoticed into the spaces between our teeth. A place that is difficult to reach with a toothbrush. However, interdental brushes are ideal for keeping them clean. You should integrate them into your dental hygiene routine once a day to prevent tooth decay. 

Sugary drinks

When it comes to drinks, the more colourful they are, the less healthy they are. Lemonades as well as orange and apple juices contain sugar and acids that are very harmful to our tooth enamel. Not so bad, you swallow them quickly? Unfortunately, this calculation doesn't add up. Every sip causes contact with the teeth and can, for example, gradually erode our enamel (tooth erosion). However, if you don't want to give up sodas and spritzers completely, you should at least not reach for them all the time in order to minimise tooth contact. It is better to have the sweet drink when there is a meal on the table anyway. If you want to make it even better, drink the soft drink from a straw - this protects the teeth a little more. For optimum dental health, however, it is advisable to avoid soda altogether and opt for water. 

Hidden foods that are harmful to teeth

And beware: anyone who thinks they are on the safe side with light drinks such as Diet Coke is unfortunately in for a disappointment. Even if such drinks are sugar-free, they contain ingredients such as citric acid or phosphoric acid, which attack the tooth enamel and thus favour tooth decay. 

 

Smoothies

While we probably all know that we are not doing our teeth any good with cola, sweets and the like, it is not always quite so obvious with some other foods that the industry wants to make palatable. This applies, for example, to the "healthy" smoothies that are often available in the chiller cabinet and promise a good portion of fruit. However, they also contain (too) much sugar - in fact, many products contain about the same amount as a lemonade or cola. It is better to make your own smoothie from fresh fruit at home. And don't just use fruit, but also vegetables such as cucumber or spinach leaves. 

 

Fruit yoghurts

Also bad for our teeth: fruit yoghurts. Here, too, some people may be fooled. After all, yoghurt is generally considered to be healthy and - as you can read above - also good for our teeth due to its calcium content. However, if we opt for the fruit variety instead of natural yoghurt, it's like eating a sweet for our teeth. This is because fruit yoghurts contain a lot of sugar. Some of them even cover almost half of the recommended daily sugar intake for adults. The good news for all fruit yoghurt fans: just make it yourself! Not only does it taste delicious, it's also good for your teeth. Because fruit, as healthy as it is, damages our teeth with its fructose and acids - but if we mix it in natural yoghurt, it is gentler to consume. 

 

Ready-made salad dressings

Another hidden sugar trap is ready-made salad dressings, which you can often find in pretty bottles in the supermarket chiller cabinet. They usually look very healthy, but are often full of sugar. And the acidic vinegar they usually contain also attacks the tooth enamel, which jeopardises the stability of the teeth and can lead to hypersensitive tooth necks. 

 

Ready-made pizza

Don't be fooled by savoury pizzas from the frozen food aisle. Even if they don't taste of sugar at all, ready-made pizzas still contain it in not inconsiderable quantities. Of course, you can still enjoy them from time to time if you don't have time to cook - but the same applies here: Don't forget to brush your teeth afterwards.

Tooth discolouration due to food?

Unfortunately, there are foods that taste delicious but leave unsightly marks on our teeth - namely by staining them yellow or greyish. Here are some of these culprits. You don't have to avoid them completely, but you should pay close attention to your oral hygiene after eating them. 

  • Cola (also Cola Light)
  • Soya sauce
  • Iced tea
  • Curry spice
  • Balsamic vinegar
  • Saffron
  • Blueberries
  • White wine
  • Rosehip tea
  • Sour cherries
  • Herbal teas
  • Grape juice

Good to know: 

Did you know? An incorrect tooth brushing technique can also cause yellow teeth, because too much pressure can "scrub away" the enamel and the yellowish dentin then shines through. You can find out how to brush your teeth properly and what you need to bear in mind here: 

Instructions: Brush your teeth properly

Can dental problems be remedied with home remedies? 

What should you do if a poor diet has already caused damage to the oral cavity and led to gum inflammation, loss of tooth enamel or hypersensitivity? Then the clear motto is: off to the dentist! For all complaints relating to teeth and gums, you should seek medical advice first and not put it off for too long. 

Once the dentist has made a diagnosis and, ideally, found the cause of your problems, you should follow the treatment he or she suggests carefully. You can also try one or two home remedies to support the healing process. However, bear in mind that there is often no scientifically proven effect of such home remedies. Here we present three popular home remedies. 

Tea tree oil

Many people swear by tea tree oil for all kinds of germs - including toothache caused by infections. The oil is said to have a pain-relieving and anti-inflammatory effect. It is either applied directly to the painful area - but you can also mix it with lukewarm water and rinse your mouth with it. Bear in mind, however, that tea tree oil is not authorised as a medicine and has therefore not been tested for its effectiveness and health risks. And there are indeed said to be risks: The terpenes in the oil can be harmful to health when undiluted and highly concentrated. It may even cause drowsiness and impaired consciousness. So it's better to try tea tree oil slowly and see how it works for you. 

Camomile tea

Chamomile tea has an antibacterial, analgesic and anti-inflammatory effect. You can rinse your mouth with it - for example, if you have an ulcer in your mouth or your gums are inflamed. It is recommended to boil the tea fresh, then leave it to cool and rinse with it several times in succession. Incidentally, sage, thyme and myrrh are also said to have a similar effect. 

Sea salt

Sea salt is one of the established household remedies for toothache. It has a disinfectant effect and is perceived as pain-relieving. To use it, you can dissolve the salt in warm water. Once the water has cooled down, it is recommended that you rinse with it for a maximum of two minutes and then spit the water out again.

Conclusion: The right diet helps to achieve healthy teeth

Eating a healthy diet is not that difficult. Basically, it corresponds to the nutritional recommendations that apply to our general health. In other words: low sugar and carbohydrates, few convenience products and lots of vegetables! Only when it comes to fruit should people who pay particular attention to their teeth take a closer look. This is because fructose and acids damage the teeth. However, there is no need to avoid this healthy snack between meals. It's just that you should take dental hygiene particularly seriously. This means brushing your teeth sufficiently and using interdental brushes for the spaces between your teeth. Despite a healthy diet, it is often not possible to completely protect yourself from a more aesthetic problem: Tooth discolouration. Even the healthiest foods such as green tea, beetroot or spices can cause an unsightly yellow tinge. We explain how to get beautiful, white teeth here in our article: "What to do about yellow teeth?"
