Should You Brush The Teeth After Meals?

It may sound like a great idea to run off and brush your teeth as soon as you have eaten, but depending on what you have just consumed, it may be the worst thing for your pearlies!

Acids from citrus foods and drinks, vinegar, tomatoes and sodas for example cause a natural chemical erosion on your tooth surface. This also happens when you have something high in sugar. The plaque, or bacteria in your mouth, convert the sugars into acids to create further damage to your teeth.

The saliva helps to neutralise the pH in the mouth, but when this level drops to below a pH level of 5-5,2, minerals are drawn out of the tooth and you need to give the saliva about 30 minutes to help neutralise this and to stop the demineralisation process. If you brush over your teeth while they are being chemically attacked, you have a far greater chance of creating even more erosion. Think about pouring acid onto a counter top and leaving it for 2 minutes, or scrubbing in it for 2 minutes. Which do you think will cause even more damage? Now, the same goes for your poor teeth.

Try to limit your sugars and acids to meal times so that the teeth spend more time remineralising during the day, than demineralising. The biggest culprit is often the fruit salads at breakfast, and the orange juice. If you know you are going to have this and have to rush and brush your teeth and leave for the day, rather brush first and rinse with mouthwash afterwards. If you have no bacteria in the mouth before you eat, you have nothing there to make use of what you are taking in!

Snack on yoghurts, nuts, provitas and cheese for example between meals. Try not to sit and have coffee and sugar with biscuits from one meal to the next, or to eat oranges all day long, and sodas are a killer for your teeth, even if its just soda water. Try to limit the amount of soda you have to a can a day……and remember, it’s all about moderation!
