As a parent you are concerned with a number of issues involving your child's health, not least involving their teeth. One of the most common is the thumb-sucking. While then thumb-sucking is a cause for concern, it is quite normal and is not regarded as dangerous in infants and children are very young.

Soon after their primary teeth begin to erupt, swallowing pattern changes and they begin to relax the tongue on the roof of the mouth just behind the front teeth during swallowing. For most children thumb sucking begins to fade as swallowing change their patterns.
Some children, though, continue to old habits even their permanent teeth begin to come in. When they suck their thumbs tongue continues to rest between the front teeth, which over time can interfere with how they are progressing.
This can lead to "open bite" in which the upper and lower teeth do not meet properly, a problem that typically require orthodontic treatment to correct it.
For this reason, the dentist usually recommends encouraging children to stop mother-sucking at the age of 3 (18-24 months to stop using pacifiers). The best approach is positive reinforcement – rewarding appropriate from time to time to the appropriate behavior: for example, praise them as the son of "big" or women when they have gone a long period of time without sucking her thumb or pacifier.
