In brief: None

None. Baby teeth fall out.
New teeth replace them. If you are still doing it after your permanent teeth come in, then you might have bigger problems to worry about than just your teeth.

Thumb sucking can cause a sticking out of the upper front teeth and distort the jaw shape. The back part of the upper jaw can become narrower. Growth of the lower jaw can be retarded and both cause bite problems. These problems will require orthopedic correction and braces at a later age. Failure to correct may be a factor in developing obstructive sleep apnea as an adult.

In brief: Bite problems

Thumb sucking puts unusual press pressure on the upper and lower front teeth causing in some cases poor growth patterns that cannot be corrected with braces later on, but might need surgical correction.

In brief: Open Bite...

Bony malformation or an open bite may be caused by prolonged thumb sucking.
.. This can result in mouth breathing. If at all possible, help your child to stop thumb sucking with a natural method. If necessary a dental appliance can be used to discourage thumb sucking.
