A. To start with, I would strongly advise that you have orthodontic treatment first. This will move your teeth into a better position. Your dentist was right when she said that you can then have them filled to look better. If you want veneers at that time, this can also be done and the drilling of your natural tooth would be quite minimal. If you choose not to move your teeth into a better position first, then veneers may not be the best option. you will more than likely need crowns- and to prepare for the crowns will need more drilling- and may compromise the health of these teeth. This means that they may die and need root canal therapy. It IS an option- but perhaps not the best option. THis is just something for you to consider.
As for your daughter, there is no harm in getting an orthodontic opinion at the moment. She may not be able to start any treatment just yet, but it is always good to know. Hope this info has helped you.
