Avoid marks on your teeth
You must avoid all fizzy and sports drinks (Coke, Club Orange, Lucozade etc.) even the diet varieties. If taking fruit juice or smoothies, they should only be taken once a day at mealtimes. Diluting orange, even the ‘no added sugar’ variety should only be taken at mealtimes. The only safe drinks to be taken between meals are water, milk, tea or coffee with no sugar.
Marks will occur on your teeth unless you follow the above instructions, especially avoiding fizzy drinks. You must also brush your teeth well and use fluoride mouthwash for the complete duration of your orthodontic treatment. You will not know that you have marks on your teeth until the brace is removed. By that time, it is too late to reverse these marks. In most cases, the marks are permanent and will ruin the appearance of your newly straightened teeth.
