How much damage do acidic foods actually cause?
Teeth are directly damaged from the consumption of acidic foods. When a person eats acidic foods, tooth enamel becomes damaged, leading to erosion. When combined with sugar, this can also lead to decay.
The over-consumption of acidic foods is becoming quite an epidemic, with as many as 60% of children showing evidence of tooth erosion, according to the British Dental Association.
The process of erosion
The reason why acidic foods are so harmful is their pH level, which causes tooth enamel to wear away. As a result, affected teeth begin to discolour, teeth begin to weaken, and tooth sensitivity becomes a real issue over time. Demineralisation will also occur – which can eventually lead to tooth decay.
The process of acid erosion is as follows:
- Tooth enamel becomes weakened
- Teeth become visibly thinner
- Eventually, teeth can appear transparent
- Discolouration begins as the yellow dentine layer becomes more visible
- Teeth begin to look dull
- Further risk of tooth decay and tooth sensitivity
Harmful food and drink
Some acidic foods, such as citrus fruits, are more obvious than others. But did you know that coffee and alcohol was acidic too? Other harmful foods and drinks with a high acidity level include:
- Lemon juice
- Orange juice
- Sports drinks
- Carbonated soft drinks (including diet ones)
- Dried fruit
- Tonic water
- Plums
- Berries
- Pickles
- Vinegar
- Salad Dressing
- Tomatoes
Reducing the impact of acidic foods
Ultimately, it’s a good idea to avoid acidic foods where possible, but this isn’t always an option. Plus, some acidic foods offer many health benefits – so eat them in moderation rather than cut them completely out of your diet.
In cases where you’re consuming acidic foods, team them with alkaline foods or lower pH foods to tone down the acidity of a meal and neutralise the acid on and around your teeth. Higher pH foods that are more alkaline include:
- Nuts
- Cheese
- Fish
- Vegetables
- Oatmeal
- Bananas
- Eggs
- Whole grains
Popular combinations include fruit and nuts, juice and yoghurt, and wine and cheese. These perfect pairings neutralise acidity and promote remineralisation of tooth enamel.
After eating or drinking acidic foods or drinks, enamel becomes softened. While it’s a good idea to brush your teeth after a meal, brushing too soon will only speed up the process of acid attack as you brush and damage your acid-coated teeth. Instead, have plenty of water to drink after your meal and consider chewing sugar-free gum. Both of these activities will produce saliva, which will cleanse your mouth. Thirty or so minutes after a meal you can think about brushing your teeth.
