It is important to get into a regular habit of good oral hygiene. In particular, regular teeth brushing and cleaning between teeth.
Brush your teeth at least twice a day. Use a soft-tufted brush and a toothpaste that contains fluoride. The head of the brush should be small enough to get into all the areas of the mouth. Spend at least two minutes brushing, covering all areas (the inside, outside, and biting areas of each tooth). Pay particular attention to where the teeth meet the gum. Get a new toothbrush every 3-4 months. Studies suggest that powered toothbrushes with a rotation-oscillation action (where the brush rapidly changes direction of rotation) remove plaque and debris better than manual brushes. Ideally, brush your teeth either just before eating, or at least an hour after eating. The reason for this is to help prevent tooth erosion. Many foods contain acids. In particular, fizzy drinks (including fizzy water) and fruit juices. After your teeth are exposed to acid, the enamel is a little softened. But, the action of calcium and other mineral salts in the saliva can help to counteract and reverse this softening. Therefore, do not brush teeth immediately after eating when the enamel tends to be at its softest. In particular, after eating or drinking acid foods and drinks. It is best to wait at least an hour after eating or drinking anything before brushing.
Cleaning between teeth
Clean between your teeth after brushing once a day, but ideally twice a day. This is to remove plaque from between teeth. Dental floss is commonly used to do this. However, some studies suggest that small interdental brushes may do a better job than floss. The aim is to clean the sides of the teeth where a toothbrush cannot get to, and clear the spaces between teeth (the interdental spaces) of debris. Some people who have not cleaned between their teeth before are surprised as to how much extra debris and food particles can be removed by doing this in addition to brushing. If you are not sure how to clean between your teeth, then ask your dentist or dental hygienist. Briefly: normal floss looks a bit like cotton thread. Cut off about 40 cm. Wind the ends round your middle fingers of each hand. Then grab the floss between the thumbs and first finger to obtain a tight 3-4 cm section which you can pull between teeth. Gently scrape the floss against the sides of each tooth from the gum outwards. Use a fresh piece of floss each time.
Some people prefer floss tape which slides between teeth more easily than normal floss. Also, some people use disposable plastic forks with a small length of floss between the two prongs. These may be easier to hold and manipulate. However, they are expensive. Some people use sticks, or small interdental brushes to clean the space between the teeth. The gums may bleed a little when you first begin to clean between your teeth. This should settle in a few days. If it persists then see a dentist, as regular bleeding may indicate gum disease.
Food and drink
Sugars and sugary foods in the mouth are the main foods that bacteria thrive on to make acid which can contribute to tooth decay. Acid foods and drinks are also a main factor in tooth erosion. So, some tips:
- Limit the amount of sugary foods and drinks that you have. In particular, don’t snack on sugary foods.
- Try to reduce the amount of acid in contact with your teeth. So, limit fizzy drinks (including fizzy water) and fruit juices as these tend to be acidic. Perhaps just limit yourself to one fizzy or fruit juice drink a day. Otherwise, choose drinks that are much less acidic, such as still water, and milk, tea, or coffee (without sugar).
- Drink any acid drinks, such as fizzy drinks and fruit juices, quickly – don’t swish them around your mouth or hold them in your mouth for any period of time.
- Brush your teeth at least an hour after eating or drinking anything – especially acidic foods and drinks. (See above for reasons.)
Likewise, do not brush your teeth within an hour of vomiting (as stomach acid will be part of the vomit). If you are taking care with these tips, you will have a bigger chance to prevent tooth erosion. which affects the entire surface of the tooth.
