Q What is a crossbite?
A A crossbite is when the teeth come together but
either inside or totally outside their correct positions. The most
common crossbite occurs when the top back teeth are inside the lowers
usually on one side only.
Q How can a crossbite be rectified?
A In the most common occurring crossbite, the upper
tooth arch can be widened.
Q What is a Rapid Maxillary Expander?
A A Rapid Maxillary Expander is a brace which is fixed
to the upper teeth. It has a screw in the middle of the palate.
Q How does the Rapid Maxillary Expander
A The screw in the middle of the brace is turned twice
daily for two weeks. This very quickly expands the upper jaw.
Q Will it hurt?
A There is some discomfort for the first two or three
days. This can be controlled with paracetamol or your preferred pain
Q How long will the Rapid Maxillary Expander need to be in
A The Rapid Maxillary Expander will need to be worn for
a minimum of three months.
Q Will there be any permanent damage?
A The fixed brace expander is not in place long enough
to cause any damage. It will be replaced with a removable retainer after
Poor cleaning and too many fizzy drinks, however, can cause permanent
decay marks around the fixings. The importance of thorough brushing and
the use of a fluoride mouthwash cannot be emphasised enough.
Q Is the treatment permanent, or will I
need additional future treatment?
A The correct use of the removable retainer for 12
months after the Rapid Maxillary Expander has been replaced will usually
ensure the improvement is permanent.
