This type of brace is used to encourage your jaw to grow back into the correct position. Twin blocks look bulky, but they are the fastest, most effective brace to correct the way your teeth and jaw meet together.
It will only take a couple of days to get used to wearing them and you will quickly adapt to speaking with your brace in place.
Twin blocks should be worn for a minimum of 22 hours per day, every day but may be removed for eating, cleaning and playing contact sports and swimming.
Treatment time is usually 6-12 months followed by a further 12-18 months treatment with fixed braces.
