Whether you’re missing one or two teeth or an entire arch, it’s important to replace them as soon as you can as your situation is likely to worsen. As the remaining teeth take on extra work to compensate for the missing teeth, they start to wear out and this can lead to further tooth loss over time. Teeth adjacent to gaps also shift in an attempt to close the space, causing misalignments which make it more difficult to bite and chew and may also cause pain. Missing teeth and bone deterioration can also cause your face to sag, giving it an aged appearance.
