Many people are born with crooked teeth and looking for a cost-effective way to straighten them. The cheapest way to align your teeth is to take the traditional route with metal braces.  Removable plates are not a true alternative to braces or aligners as they can only provide limited corrections. Along with this basic description you must also know why people generally need alignment of teeth. The most common dental problems relating to alignment include the following,

• Crossbite: when your upper teeth come together inside your lower teeth (posterior crossbite), or when your lower teeth come together inside your upper teeth (anterior crossbite).
• Open Bite: when your front teeth come together but your back teeth do not (posterior open bite), or your back teeth come together but your front teeth do not (anterior open bite).
• Deep bite: when the front teeth on your upper jaw cover your lower teeth too much.
• Crowding: when there’s not enough space for all of your teeth.
• Spacing: when there’s too much space between your teeth.
• Protrusion: when your front teeth stick out too far.
• Retrusion: When teeth are placed too lingually.
