The Role of Nutrition in Maintaining Optimal Oral Health
04.04.2025
Most patients have a pretty good grasp on how to care for their oral health at home. From a young age, we are taught that we need to brush our teeth twice a day, floss between our teeth, and visit the dentist regularly. While this is a great place to start, there is more you can be doing to help protect your teeth, and it has a lot to do with your diet.
You might think that it’s all about the foods that you avoid, but there are benefits to be found in increasing certain foods in your day-to-day diet. In this guide, we’re looking at the role nutrition plays in maintaining excellent oral health, and how your everyday choices can have a lasting impact on the health of your teeth and gums.
The link between nutrition and oral health
There are a few different ways that nutrition impacts your oral health. First and foremost, there are certain food choices that will have a negative impact on your teeth. Some of these are very obvious, but others are less so.
The second way that your oral health can be impacted by nutrition is in the presence of vitamins and minerals in your food. These can help to strengthen your teeth from the inside and set you up for a lifetime of healthy teeth and gums.
If you’re ready to start improving your oral health through nutrition, follow these simple tips for healthier teeth and a happier smile.
Limit your sugar intake
Most people know that sugar is bad for their teeth, but not a lot of people know why and how to limit the damage. Did you know it’s not just about how much sugar you have, but also about when you enjoy it. Knowing this information can help you to continue enjoying sugar in a healthy way without impacting your teeth.
Snacking on sugary snacks between meals is one of the worst nutrition mistakes you can make. Between meals, your mouth isn’t producing the same amount of saliva, so you’re much more likely to be left with sugar and food debris on your teeth.
To balance the impact of sugar, you can enjoy a small sweet treat after a main meal. Washing this down with water can also help to limit any damage.
Increase your calcium intake
Calcium is essential for bone strength and it is actually stored in your teeth. If you aren’t getting enough from your diet, your body will take it from the stores in your bones and your teeth, which can leave your teeth weakened and more likely to suffer from decay.
To prevent this, look for calcium-rich foods you can add to your diet. This could include things like dairy, leafy green vegetables and fortified bread and cereal.
Alongside your calcium intake, you should also prioritise vitamin D and vitamin C. These are essential for bone health, gum health and fast wound healing. A vitamin C deficiency, for example, could leave you vulnerable to gum disease.
Avoid staining food and drink
Your teeth might look solid, but they actually have tiny holes which allow staining particles from food and drink to enter. When these get trapped in the tooth, you might be left with dull and discoloured teeth.
The biggest culprits are things like spices (turmeric, paprika, curry powder), red wine, coffee and tea, sticky sauces (ketchup, barbecue sauce), and dark fizzy drinks (cola).
While staining isn’t necessarily bad for your oral health, it can damage your confidence and make you reluctant to smile. The only way to address dental staining is with professional teeth whitening, as brushing alone isn’t enough.
Fibre and the role of chewing
In order to maintain a healthy mouth environment, you need to make sure that you are eating a diet rich in fibre and that you are chewing your food well. Unfortunately, many dental problems can lead you to avoid certain foods that require lots of chewing, and this can compound the issues.
A diet that is high in fibre will require a lot of chewing at every meal time. Chewing is the mechanism that helps to stimulate saliva production, and saliva is essential for digestion and maintaining a healthy mouth. It helps to neutralise harmful acids, clear away food debris, and prevent dry mouth.
