Get a cleaning and exam before you get braces
Your dentist will examine your teeth to make sure you have no cavities. All cavities need to be filled before you get braces. Brackets or bands may cover surface of cavity so they will need to filled before the orthodontist can place your braces. You will need a good cleaning to remove plaque and tarter. It is harder to clean teeth once braces have been applied. You will also find that flossing will become more difficult.
I know this sounds crazy, but eating certain foods will be off limits. Hard crunchy things like hard pizza crust, popcorn, nuts and even carrots. Eat a few things before you are limited.
Stock up on supplies
You will go through tooth brushes more often because bristles break down more with brackets. You may want to look at a sonic toothbrush to help keep things healthy. You may want to look at flossing options for braces. Everyone likes different products. Get a few and experiment which one works for you. There are some rinses designed for braces. Fluoride rinses can be helpful. Very good oral care will help keep your teeth healthy during orthodontics.
Take a few photos
Teeth move quickly and it is nice to see where your teeth started and the results when you are finished. Promise me you will forget the beginning.
Get some soft foods
Teeth tend to be a little sore after placement. A few soft foods in the house will make it easier to eat and keep your nutrition up. You will be better in a couple of days. Adjustments do not make the teeth as sore as the placement appointment.
Remember it will all be worth it in the end! A beautiful smile it a great result.
