Great question! It is very common to file teeth during Invisalign treatment to create spaces to move the teeth to the correct position.
However if the crowding is too severe, then the alternative will be to extract teeth. An assessment by the orthodontist will be able to determine if filing is necessary and the position for filing the teeth. For more information, do come down to our NDCS inaugural public forum “Smile Sparkle Shine- a public forum on Oral Health” on 24 March to find out more!
