A: Having crooked teeth can often lead to a bad bite, which means your teeth don’t fit together properly so they are wearing unevenly. Without treatment, excessive wear can cause cracked teeth and lead to more dental work. Orthodontic treatment can improve function, creating teeth that last longer, work more efficiently, and usually look better. Because properly brushing and flossing your teeth is more difficult with crooked teeth, having a straighter smile will promote proper oral hygiene and keep teeth healthy for the rest of your life.
