Am i allowed to eat smoothies/ ice cream? even though i just got my braces yesterday

Yes just brush after: Yes smoothies/ice cream are ok as long as you brush soon after. Also, many orthodontists now use "state of the art", heat-activated arch-wires. So it is advisable to rinse with very warm water as soon as possible after ingesting anything cold. This will re-activate the arch-wires and keep your teeth moving as efficiently as possible. The main foods you should avoid are hard or "sticky" foods.

Yes: You may have either of these treats the moment the braces are bonded to your teeth.
